Scotland’s seas are amazing, and they matter to us all. Many people will be spending time on Scotland’s coasts this summer – rain or shine. Even just a day trip to the beach can feel like a little holiday, refreshing and replenishing us.
That’s not all, of course. As anyone who watched the ocean episode of David Attenborough’s Wild Isles series will know, our seas are home to the most fantastic array of wildlife, much of which is hidden deep beneath the waves. They’re of huge importance for the climate too, as ocean ecosystems can store even more carbon than those on land.
Our seas are a vital resource, central to the lives of communities that rely on marine industries like fishing and wildlife tourism. And they are a source of food.
We all want Scotland’s seas to be healthy and teeming with life. But the threats facing our seas are immense, and we need to act fast to help them recover.
Why do we need to restore our seas to health?
The scientific evidence makes it clear that Scotland’s marine species and habitats are in serious decline. Most of our seabed is in poor condition, with some habitats, like seagrass and flame shell beds, covering just a tiny fraction of their former areas.
Five million seabirds breed around our coastline every year, but many species are in steep decline due to climate change, unsustainable fisheries, disease, pollution and the impact of invasive non-native species.
Recent bird flu outbreaks have made things worse. It’s estimated that up to 90% of some great skua breeding populations may have been lost in Shetland’s Hermaness Nature Reserve, for example. Great skuas – or ‘bonxies’ as they are also known – are top predators, and this level of loss will have a dramatic impact on vulnerable marine ecosystems.
The effects of climate change are also making themselves felt. Scotland’s seas have experienced extreme and unprecedented heatwaves this summer, with water temperatures up to 4°C above normal in some places. Marine heatwaves pose a serious threat to wildlife, risking high levels of mortality and loss of breeding grounds. They have led to concern for industries such as salmon farming that rely on healthy seas.

Ocean recovery zones
So what can we do to protect our seas and help them recover?
Tackling climate change is part of the answer. But caring for our seas and managing them well will also require a number of carefully planned and interlinked measures. Experience worldwide shows that strictly protecting certain defined and limited areas from damaging industrial activity is a key piece of the jigsaw.
Strictly protected areas provide dedicated havens for vulnerable and depleted marine life to recover. They become, in effect, ocean recovery zones. As marine animals and plants are able to grow larger and live longer, they reproduce more, and their increasing populations can overflow into surrounding waters. This helps marine life recover both within and beyond the strictly protected area. And these ecological benefits in turn support marine industries, including fishing and tourism.
Internationally agreed standards, including the EU Biodiversity Strategy 2030, call for at least 10% of the ocean to be strictly protected to enable large-scale ecosystem recovery. Currently, less than 1% of Scotland’s seas are strictly protected from damaging human activities.
Scottish Government proposals
The severe threats facing our ocean, and the overwhelming evidence of the benefits of strictly protected areas, led the Scottish Government to release proposals earlier this year to create ‘Highly Protected Marine Areas’ (HPMAs) in 10% of Scotland’s seas. These areas would have been given the strongest possible form of protection.
The proposals didn’t include any suggested sites for HPMAs. In part due to the uncertainty involved, HPMAs became a controversial topic, with many members of Scotland’s coastal and island communities in particular expressing concern that restrictions on fishing would damage the sustainability of areas dependent on the industry.
In June, the Scottish Government announced, ‘the proposal as consulted on will not be progressed. That means that we will no longer seek to implement HPMAs across 10 per cent of Scotland’s seas by 2026.’ However, Cabinet Secretary Mairi McAllan confirmed that the Scottish Government remains ‘firmly committed’ to ‘enhancing marine protection’, recognising the EU target of strictly protecting at least 10% of its seas by 2030. She also stated her commitment to ensuring that ‘communities across Scotland are central to the process’, and emphasised the role of coastal and island communities in shaping future policy on Scotland’s seas.

Communities at the heart of ocean recovery
Community involvement will indeed be key. While healthy seas are vitally important for all of us, they play a particularly central role in the lives of Scotland’s coastal and island communities.
It’s crucial that measures to protect our seas, including strictly protected ocean recovery zones, are designed collaboratively, with these communities engaged at the heart of the process. Our best chance of restoring our seas to health will come from communities, environmental organisations, fishers and other marine industries working together with government.
That’s why in March we and other organisations wrote to the Scottish Government calling for improved stakeholder participation along with independent scientific scrutiny of its proposals for marine protection.
One of the only parts of Scotland’s sea that already has strict protection, in north Lamlash Bay off the isle of Arran, has protected status brought about through pressure and organising by local people, showing the importance of community involvement. Since the Lamlash Bay ‘no take zone’ was established, the area has seen dramatic ecological improvement. We need to see this success replicated around Scotland’s coast.
Everyone in Scotland wants to see our seas in a better condition, and creating ocean recovery zones will be a crucial step to restoring our ocean biodiversity.
Scottish Environment LINK members are calling on the Scottish Government to honour its commitment to set Scotland’s seas on the path to recovery by 2030, and create strictly protected ocean recovery zones in 10% of Scotland’s seas.
The Scottish Government is expected to develop new proposals this autumn for enhancing our marine environment, and we’re looking forward to contributing to this urgent work. Now is the time to work together to find transformative ways to help restore our amazing seas to health.

There is a very strong global evidence base showing that Highly Protected Marine Areas (HPMAs) have a positive impact ecologically and can support the fishing industry. HPMAs, also known as marine reserves or no take zones, act as nurseries and refuges and as such benefit marine species and habitats both within the protected area and outside them.
Evidence from across the world shows that, on average, twice as much total fish biomass and fish density is found in the protected area than outside. These benefits can happen quickly, within a few years of protection, and can have a ‘spillover’ effect into surrounding waters.
To maximise both conservation and socio-economic benefits, HPMAs should be bordered by buffer zones to benefit low impact fishers. With such zones HPMAs can benefit sustainable fishing, and those engaged in it, while at the same time helping build up fish and other marine species populations across the wider sea and for future generations.
However, success will depend upon a collaborative approach with all stakeholders, including local communities, fully involved and engaged with support, access to advice and scientific evidence and independent scrutiny. The Scottish Government’s Just Transition outcomes are key in delivering success for coastal and island communities as well as Scotland’s marine biodiversity.
Background
The marine environment is one of Scotland’s greatest assets and a vital resource for communities who rely on marine activities like fishing and wildlife tourism. However, evidence shows a continuing decline of our marine ecosystems, impairing their ability to provide the life-sustaining benefits we all depend on.
In the Bute House Agreement, the Scottish Government committed to designate at least 10% of our seas as “Highly Protected Marine Areas” (HPMAs). HPMAs are areas of the sea that are placed under strict protection to support ecosystem recovery and protect against climate change. This is in line with internationally agreed standards for nature recovery and resilience (e.g. Global Biodiversity Framework Target 3), and follows the EU’s own 10% target for strict protection.
The effects of strict protection at sea have been widely documented globally, and growing evidence highlights the ecological and socioeconomic benefits of these marine reserves or no-take zones. The following briefing provides a non-exhaustive summary of the science available regarding HPMAs in the world.
Ecological benefits within HPMAs
Various HPMAs can be found worldwide, and research demonstrates their benefits on marine life within and outside their boundaries. The MPA guide helpfully provides a map of 226 MPAs, 114 of which are equivalent to the proposed Scottish HPMAs.1 HPMAs are equivalent to “marine reserves”or “no take zones” and have been abundantly studied across the world, in both tropical and temperate waters. Hundreds of surveys, often summarised in global or regional studies, show that protecting the marine environment from damaging activities leads to a sharp increase in abundance, average body size and biomass of marine species.2
A 2019 synthesis of current scientific evidence shows that HPMAs can provide greater benefits than lighter forms of protection. Placing areas of the sea under strict protection allows marine species to recover, by providing them a refuge to grow, age and reproduce. In their analysis of 24 no-take zones in the highly pressurised Mediterranean Sea, Giakoumi et al. (2017), demonstrated that high levels of protection have significant ecological benefits for fish biomass and equally positive effects for fisheries’ target species.3 The total fish biomass and density were on average twice as much in fully protected areas than outside. The study also highlighted that there was no difference in total fish biomass between partially protected and unprotected areas.
Ecological benefits can be observed within no-take zones only a few years after their creation, with increase in populations within two to five years.4 The impressive case of the Cabo Pulmo protected areas, in the Gulf of California, showed an almost five-fold increase of the fish biomass only a decade after its creation. Closer to home, research carried out in the small no take zone in north Lamlash Bay since 2010 shows a dramatic improvement – measured biodiversity has increased by 50%, while the populations of commercially important species are 2-3 times higher within the no take zone. King Scallop, (Pecten Maximus) populations have increased almost four-fold, with the scallops being older and producing more eggs. Surveys undertaken between 2012 and 2018 highlight similar effects on European lobsters. The experience in Lamlash Bay clearly demonstrates the potential spillover benefits to Scottish fishers from even small areas of strict protection.
Another great example of a successfully implemented HPMA is the French Marine Park of la Cote Bleue, created in 1982. The no-take zone of Carry-le-Rouet was created in 1983 and a second no-take zone, the reserve of La Couronne was created in 1996. Local fishermen played a key role in the creation of La Couronne HPMA, and the management of the two no-take zones: continuous dialogue between local authorities and fishermen led to management measures beyond the Carry-le-Rouet HPMA boundaries. In their study of six no-take zones in the Mediterranean Sea, Harmelin-Vivien et al (2008)5 confirmed an increase in the abundance, biomass and size of fishes inside marine reserves. They observed that the average biomass within the marine reserve of Carry was 16.3kg, compared to 2.4 kg outside the area.
Ecological and socioeconomic benefits beyond HPMA boundaries
Research worldwide6 demonstrates that, if implemented and managed well, HPMAs can have positive effects beyond their boundaries, supporting marine activities such as fisheries or tourism. As populations within the HPMAs increase in size, and individuals grow larger and live longer, they can reproduce more. This enhanced reproductive potential can then lead to the replenishment of populations adjacent to the no take areas – a “spillover” effect to fished areas.7 The spillover effect arises firstly, through the export of eggs and larvae outside the marine reserve, and secondly from the movement of juvenile or adult animals from the no take zone to adjacent waters. Studies in the Mediterranean confirmed the role of marine reserves in sustaining local fisheries for commercial species such as the spiny lobster, Palinurus elephas. Harmelin-viven et al (2007), observed a spill over effect in all the reserves they studied, thus demonstrating the long-lasting effects of strict levels of protection.
Spillover of fish was measured at up to 1959m from one of the reserve boundaries, and averaged over 500m across all the sites (Harmelin-Vivien et al, 2008). Evidence shows that the extent of the spillover effect depends on the pressure in the adjacent waters. Indeed, the spillover effect is predicted to be “smaller” in areas where adjacent waters are highly pressured.
However, HPMAs cannot be considered in isolation of other marine policies and management processes. Pauly et al. 2002 states that: “Marine protected areas (MPAs), with no-take reserves at their core, combined with a strongly limited effort in the remaining fishable areas, have been shown to have positive effects in helping to rebuild depleted stocks.”8
In order to maximise the conservation and economic benefits of HPMAs, LINK recommends that no take zones should be buffered by low impact fisheries zones, prioritising sustainable fishers who can benefit from the immediate spillover effect. Creating buffer zones would help protect low impact fisheries from displacement by giving them preferential access to waters. This would be part of meeting the Scottish Government’s Just Transition outcomes, underpinned by the 5 principles for a Just Transition, as set out by the Just Transition Commission in 2022. A collaborative approach with all stakeholders is essential to achieving conservation objectives, and to build support among stakeholders and wider society. LINK believes that successful engagement must include improved stakeholder participation with clear expectations, wider strategy and support mechanisms for affected activities, use of best available science and independent scientific scrutiny of proposals.

Highly Protected Marine Areas are areas of the sea that are placed under strict protection to support ecosystem recovery and protect against climate change.
The Scottish Government has committed to giving a small proportion – just 10% – of our seas this strict protection. This is in line with international recommendations for nature recovery and resilience and follows the EU’s own 10% target for strict protection.
HPMAs are well-established globally and proven to have ecological benefits, which in turn can benefit fishers. The success of the ‘no-take zone’ (an area where no fishing is allowed, equivalent to an HPMA) of Carry-le-Rouet in the French Mediterranean, created in 1983, led to the fishing industry playing a key role in the establishment of a second HPMA nearby, the reserve of La Couronne.
Why do we need HPMAs in Scottish seas?
We are facing a twin nature and climate crisis, and nature’s recovery must be central to government priorities and policies. In its latest report, the Intergovernmental Panel on Climate Change (IPCC) warned that the impact of climate change was increasingly irreversible and called for every country and sector to take drastic action on all fronts to tackle the climate crisis. Last year, the UN Secretary General declared an “Ocean Emergency” and called for collective and urgent action to restore marine life.
In Scotland, the health of our seas is vital for communities who rely on marine activities like fishing and wildlife tourism. However, evidence shows a continuing deterioration of marine ecosystems, and some of our living seabed habitats, such as seagrass, have suffered from catastrophic decline. UK administrations have collectively failed to achieve 11 out of 15 of the ‘Good Environmental Status’ targets set by the UK Marine Strategy, with seabird populations in particular continuing to decline.
Scotland’s Marine Assessment 2020 identified climate change and fishing activities that drag heavy nets across the seabed or through the water as the key pressures facing marine biodiversity.
If implemented alongside other sustainable management measures, HPMAs would provide Scotland with core zones for ecosystem recovery, helping us address the climate and nature crises and increasing our seas’ resilience to climate change. For thriving seas with healthy fish populations, we need an effective marine planning system that protects key areas, including HPMAs, so that Scotland’s seas can support species, habitats and communities.
How do HPMAs work?
HPMAs provide strong levels of protection to the marine environment by prohibiting all impacting or damaging activities in a small number of designated sites. Activities that remove or damage natural resources or that dump materials and pollutants in the sea are banned. The specific rules for Scotland’s HPMAs will be determined by the Scottish Government.
The recently published globalMPA Guide provides a helpful summary of what activities are or are not compatible with fully and highly protected areas.
HPMAs provide dedicated havens for vulnerable and depleted marine life to recover. Allowing fish, shellfish and other species to flourish in a fully protected area also benefits the many people and activities that rely upon healthy seas. The benefits from these areas overflow into surrounding waters, increasing the abundance and resilience of sea life, benefitting low impact fishing.
Analysis of the 24 no-take zones in the Mediterranean sea demonstrated that high levels of protection have significant ecological benefits for fish biomass and equally positive effects for fisheries’ target species. The total fish biomass and density were on average twice greater in fully protected areas than outside.
The community-led no take zone in Lamlash Bay off the Isle of Arran is Scotland’s only strictly protected area equivalent to a HPMA (as proposed in the recent Scottish Government consultation) and demonstrates on a small scale their potential for success. Biodiversity in the bay has increased by 50% since 2010, and the king scallop population more than trebled between 2013 and 2019. This has increased opportunities for low impact fishing and for scallop hand diving, benefitting the local economy.
Where will HPMAs be placed?
The Scottish Government is responsible for designating Scotland’s HPMA sites. Proposals will be informed and assessed by Scottish Government conservation advisors, NatureScot and the Joint Nature Conservation Committee, who will suggest whether they meet the criteria to be designated as HPMAs. Proposals from organisations and members of the public will also be invited (‘third party proposals’), which will be assessed in the same way.
It is our view as members of Scottish Environment LINK that coastal, island and fishing communities should be closely involved in the process of designation as equal partners. An effective HPMA network should be spread across both inshore and offshore waters, in areas that have been degraded or that have the potential to recover to a more natural state, and should be designed to support both ecological and social sustainability.
Can HPMAs exist alongside a viable fishing industry?
Yes – HPMAs can support a sustainable fishing industry. Where there are designated ocean recovery zones, fish stocks will increase with spillover effects in neighbouring areas. The example of French fishermen working towards additional HPMAs after experiencing the benefits of no-take zones shows that this approach can bring significant benefits to industry itself.
Where else has HPMAs?
HPMAs are a key tool to enable the protection and recovery of marine ecosystems. Globally, the number and coverage of HPMAs are increasing. TheEU Biodiversity Strategy for 2030 sets a target of ‘strict protection’ of 10% of the EU’s seas by 2030.
Various HPMAs can be found worldwide, and research demonstrates their benefits on marine life within and outside their boundaries. The MPA guide helpfully providesa map of 226 MPAs, 126 of which are under high levels of protection.
People in Scotland believe sewage and chemical pollution pose the biggest threat to the health of our seas, according to new research.
The opinion poll, conducted by Survation on behalf of the environmental coalition Scottish Environment LINK, also found high levels of public concern over litter and the impact of climate change on our seas.
9 in 10 Scots say that it is important to them personally that Scotland’s seas are in a healthy state, according to the poll. But sea health is being damaged by a range of factors, including plastic, chemical and sewage pollution.
One factor concerning environmental charities is the lack of monitoring of sewage releases in Scotland – with the public left in the dark over the scale of the problem.
Sanitary waste such as wet wipes and cotton bud sticks can end up in our seas when sewers overflow due to heavy rainfall or insufficient capacity in the network.
These storm overflows, which release untreated sewage into rivers and coastal waters, are intended to operate during extreme weather events – but the Marine Conservation Society has raised concerns that storm overflows may be being used on a more regular basis.
Evidence from Marine Conservation Society volunteer Beachwatch litter surveys suggest a higher level of sewage related debris on Scottish beaches than in England and Wales, where monitoring rules are stricter.
Scottish Water monitor only 9% of storm overflows, and are required to monitor only 3%. In comparison, over 80% of overflows in England and Wales are monitored, with a commitment for 100% to be monitored by the end of 2023.
Scottish Water reported 10,763 spills in 2021 – however, this only covers the 3% of overflows they are required to monitor, suggesting a much more widespread problem. Environmental charities have called on the Scottish Government to install electronic monitoring on all sewer overflows by 2024.
Calum Duncan, Convener of the Scottish Environment LINK Marine Group and Head of Conservation for Scotland at the Marine Conservation Society, said:
“Scotland’s beaches are beautiful – but anybody who has visited one in recent years will have noticed pollution being washed up on our shores.
“Our ocean is fundamental to life on earth, and inextricably linked to all our health and wellbeing.
“But our seas are being used as a dumping ground for sewage, plastic rubbish and ‘forever chemicals’, all of which continue to build up over time, wreaking havoc on our planet.
“We need much stronger monitoring on our sewer overflows to help target improvements and reduce the sewage and debris entering Scotland’s seas, and a ban on all non-essential ‘forever chemicals’.”
Clare Cavers, Senior Projects Manager at Fidra said:
“Evidence of pollution in our rivers and seas from invisible chemicals and tiny plastic particles is growing all the time, and a lot is known to come from sewage.
“There needs to be an urgent increase in monitoring sewage from storm overflows in Scotland, so that we can understand exactly what is coming through the sewers and where it is coming from.
“Then we can work with manufacturers, retailers and government to turn off the pollution tap and protect Scotland’s stunning seas for the next generation to enjoy.”
The UK’s fishing industry has long been a fundamental part of vibrant coastal communities, providing livelihoods to many and food to feed us, from Cullen Skink on a cold winter’s evening, to whole grilled mackerel with lemon and garlic, or scampi and chips by the sea.
However, our seas, wildlife and the fishers whose livelihoods are dependent upon healthy marine ecosystems, are suffering. International marine biodiversity targets have not been met and the UK, as a whole, has failed to meet 11 out of the 15 indicators for achieving Good Environmental Status. Commercial fishing continues to be the most widespread pressure on the marine environment but it also has real opportunity to provide solutions and help recover our seas if done sustainably.
Meanwhile, for fishers, uncertainties regarding market access and the increase in fuel prices have resulted in unemployment and family upheavals; with some fishers tying up their boats for good and having to relocate their families in search of alternative employment. It is a turbulent time for the fishing industry and they need to be given certainty.
The Discard Ban
For many years one of the key concerns over the impacts of fishing on biodiversity was the wasteful nature of many fisheries in which significant amounts of unwanted fish were dumped back into the sea, a process known as discarding.
A discard ban was introduced with the hope that it would incentivise more selective fishing and less discarding. The rule made sense, but it was poorly managed and enforced with little evidence of widespread uptake. The fact that such a policy which required fishers to significantly change the way they operated, was not accompanied by robust monitoring to ensure a level playing field, gave it little chance of success from the outset; and many saw this coming.
How do you catch a haddock without catching a cod?
In the North Sea a lot of the fish we catch are part of mixed fisheries – fish like haddock and cod tend to swim together (unlike mackerel, which swims higher up in the water column as a more exclusive and fast-moving shoal).
The problem for fishers who target these mixed fisheries is that the quota for one fish (e.g. cod), might be very low or even set to zero, while the quota for another (e.g. haddock) might be much higher. So how do you catch a haddock without catching a cod?
We are constantly learning new things about the UK’s marine life. If you chase a haddock, for example, it will likely swim up towards the surface. If you chase a cod, it will swim down to the safety of the seabed.
If you have a fishing net with larger ‘escape panels’ in the roof of the net – then you’ll not catch many haddock, but you will catch cod. Other fish can take advantage of their shape, e.g. sole, which will squeeze through fish nets with horizontal slits. Using highly selective fishing gear (that is designed taking into account fish behaviour, preferences, shape etc.) can help catch the fish you want and avoid the ones you don’t.
However, an obstacle to investing in highly selective fishing gear is that it comes at a cost. The cost of the gear itself which can run into the tens of thousands and the cost of some marketable fish that pass through the ‘selective’ gear. With very little monitoring at sea, the impact of the discard ban was not clear. While some complied and invested in new gear, others continued to operate with business as usual. Without the level playing field, which would have been achieved with robust monitoring, it created a competitive advantage for those that continued to discard.
A game-changing technology is ready for roll-out
The good news is there is a tried and tested solution that’s a win-win-win for wildlife, fishers and you: Remote Electronic Monitoring (REM) with cameras.
REM is a powerful and cost-effective tool that answers three fundamental questions: where boats are fishing, when and how they are fishing and most importantly, what is being removed from the water – target and non-target species. With a much clearer picture we can improve fisheries management, help prevent overfishing and ensure fishing is sustainable for future generations.

People are increasingly concerned with the provenance of their seafood, and the impact it has on marine wildlife. The best tool to help de-risk fisheries and give green light for access to more retailers is REM with cameras. This technology enables fishers to demonstrate to the public and retailers that they are operating in a sustainable way, using best practice and highest levels of selectivity.
REM would also empower fishers by putting them at the heart of the data collection process, bridging the gap between them and fisheries managers. Fishers spend a significant amount of their lives at sea and claims that catch quotas are out of touch with what they are seeing in their nets need to be addressed. The ‘fish-counting’ cameras provide fishers with an opportunity to document what they are seeing and feed into the science of quota setting. In the Netherlands, smart cameras have been taught to differentiate between different fish species. With ongoing developments in technology, we envisage a day where scientific data will be accessed by fisheries, managers and fishers alike, in real-time, after each haul.
REM has been tried and tested for more than 20 years and is in use across many fisheries globally. In Denmark, following successful trials, REM is being rolled out across their fishing fleet which is very similar to that of the UK. Across the food sector, it has become standard practice to safeguard work places through the use of cameras. Cameras are mandatory in slaughterhouses in the UK, with recordings processed in line with data protection requirements to address privacy issues. Fisheries should be no different.
UK governments must seize the opportunity
Following Britain’s departure from the EU, UK governments are developing new ‘catching’ policies which if done right, could both improve the health of our seas and make livelihoods more secure.
Accountability and confidence will be central principles of these new policies, however, without equipping vessels with the tools they need to provide the required levels of at-sea monitoring these policies will fall short of their objectives.
Last month, one of the UK Government’s own statutory bodies, Natural England, released a report with the key message that Remote Electronic Monitoring (REM) with cameras is vital to achieving Good Environmental Status (GES) and recommended the immediate roll-out of this technology to the ‘highest risk’ fleets such as demersal trawls to: 1) help promote compliance; 2) collect data for data-poor fisheries; 3) protect sensitive species; and 4) contribute to achieving GES.
It was disappointing that UK governments did not take the opportunity to commit to rolling out REM across the UK fishing fleet when they produced the draft Joint Fisheries Statement – a document that sets out how fisheries will be managed across the UK now that we have left the EU.
There is still an opportunity, however, as the final version of the JFS has yet to make an appearance. We believe there is still an opportunity for all four government administrations to provide a unified voice in support of REM with cameras being a key element of fishing in UK waters. UK governments are still to develop their individual plans or ‘catching policies’ which should require REM as a key means of helping delivery and providing support.
The Scottish Government is to be credited for taking forward REM with consultations for roll-out to the scallop dredge and pelagic fleets, however, the concern is that plans to roll-out REM are not prioritising the vessels which need it the most.
We know that gillnets and longlines carry some of the highest risk of seabird bycatch while whales are often accidentally killed in creel lines and other cetaceans like porpoises become entangled in gillnets and dolphins are caught in trawl nets. We are yet to achieve good environmental status for whales and dolphins, and the situation for seabirds is getting worse instead of better1 We also know that demersal trawls have the highest risk of shark and skate bycatch and discarding. REM can help to monitor bycatch rates and the use of mitigation measures.
Whatever changes are implemented in the new catching policies, we believe that the degree to which they are underpinned by robust at-sea monitoring with cameras will be a defining factor in achieving sustainable fisheries in the UK.
The question is… when will the UK governments step up and roll-out REM to the fleets that highest-risk fleets and embrace the benefits that REM brings for wildlife, fishers and the consumer?
Current levels of wildlife protection in Scotland’s seas are too weak, according to an opinion poll gauging the views of Scots on the health of the marine environment. Only around half of respondents felt that Scotland’s seas are in good condition, with 46% stating that the quality of Scotland’s seas have worsened in the last 10 years. Pollution, the effects of climate change and industrial fishing are cited as the greatest perceived threat to our seas.
Meeting commitments to protect at least 30% of Scottish seas for ecosystem recovery by 2030
Evidence is growing to show that the health of Scotland’s seas has been in decline for some time. Seabed habitats are a shadow of what they once were, fish stocks have dwindled, and coastlines are changing due to the impacts of climate change. By law our seas should have been in ‘Good Environmental Status’ by 2020 (seas are healthy and productive and resources are being used at sustainable levels), but unfortunately all governments across the UK failed to achieve this for 11 out of 15 indicators. And that’s not to mention the bigger picture that this is a worldwide trend, with the earth now widely recognised as being simultaneously in the midst of a climate emergency and nature crisis – a de facto ocean emergency. Arguably we now need to go further than GES. (more…)
The coastal waters of Scotland are home to several marine mammal species like bottlenose dolphins, harbour porpoise and seals. It’s more common than you think to encounter them and, working for WDC on our Shorewatch project, I am fortunate enough to record numerous sightings of whales, dolphins and porpoises around the Scottish coastline. As a keen paddleboarder I have also had several encounters with dolphins, porpoise and seals while on the water.

Watching whales and dolphins wild and free is an incredible experience and provides wonderful memories that will stay with you for years. It can even shape a young person’s life. I still remember my first cetacean sighting at 14 years old, from the Isle of Skye – it was a minke whale – and that day I decided I wanted to be involved in marine conservation.
Each year more and more people are recognising that our marine environment is a place to be celebrated and enjoyed, but this also leads to marine wildlife having to share their homes with more people, which sometimes can lead to negative impacts on the creatures we love.

Disturbance to whales, dolphins, porpoise, and seals from watercrafts is a serious threat to their survival. Only this year a common dolphin was killed after a boat strike, while hundreds of seals have undergone harmful injuries after being driven from their resting sites. As several of our marine species live in coastal waters, there is a high likelihood that we may encounter them when out on the water. Without the right education it can be too easy to cause a disturbance. Disturbance does not always result in death or physical injury, it can alter natural behaviours like communication, resting, feeding, breeding and soliciting, and can drive marine wildlife away from important areas used as feeding grounds or nurseries. Whales, dolphins, and porpoises need to feed, rest, socialise and reproduce to stay healthy and to keep their populations strong. If we get too close, we can disrupt their natural behaviours and unwittingly cause changes to an individual’s breathing, hamper their ability to feed, or stop them getting the rest that they need. Mothers with calves are particularly vulnerable.
You might think it’s just noisy boats and jet skis that are a problem, but kayakers and paddle-boarders can disturb dolphins too, and it’s important that we all know how to behave around marine wildlife, so we can ensure their and our safety. That’s why WDC launched our #RudeToIntrude campaign to raise awareness of marine mammal disturbance, what it looks like, and how to avoid causing a disturbance and how to report any illegal activities.
We all need our personal space – so do whale and dolphins.
Following this advice will help you to remain within the law and reduce the risk of you disturbing whales and dolphins.
Keep your distance. Avoid getting too close, especially if calves are present.
Approach carefully from behind and to the side, make sure you are aware of best practice.
Three is a crowd – there should never be more than two watercrafts within the 300 metre ‘caution zone’
Don’t overstay your welcome – 15 minutes is enough.
Avoid repeated disturbance; consider staying away if the wildlife has already spent a prolonged period with vessels nearby.

It’s #RudeToIntrude. To avoid disturbing wildlife,DO NOT:
Make sudden changes to speed and direction
Approach from directly in front or behind
Drive between or scatter groups, especially mothers and calves
Chase or repeatedly approach individuals
Box them in – take care not to trap individuals between your vessel and other vessels or the shore
Swim with them or try to touch or feed them.
Disturbance of whales and dolphins is an offence, whether it is intentional or not.Reporting reckless or intentional disturbance will help protect whales and dolphins, enabling everyone to enjoy our waters.
If you see someone disturbing dolphins, porpoises or whales, do not approach them yourself. Do report them to the police by calling 101.
Tell the operator that you are reporting a wildlife crime and ask for an incident number to ensure that reports can be tracked.
Report the incident, letting them know:
the date, time and location of the disturbance
the behaviour of any vessels and of the whales and dolphins before, during and after the event
if possible, the species involved
the duration of the interaction
any identifying features of the people or vessel involved, such as the boat name and the clothes worn.
If possible, take photographic or video evidence of the disturbance. Photos and video of behaviour before and after the disturbance or from different angles can also be very helpful!
