Sustainability in Scotland's Seas

Brown crab

Populations of brown crab are distributed all around Scotland’s coasts. Night-time foragers, Brown crabs are caught by creels and are one of the big mainstays of our inshore fisheries. Crabs can grow to over six kilos in weight and live to around 25-30 years. About one third of the weight of a crab is edible and the white and brown meat is variously used in soups, pates and delicious simply dressed.

Amazingly the Scottish fleet catches more brown crab by weight than fish species like hake or whiting, averaging around 11,000 tonnes per year. The vast majority is landed to Scotland, with big catches going to harbours such as Brora, Gardenstown, Scrabster and Ullapool. Orkney sustains the country’s biggest Brown crab fishery with sizeable landings at Holm, Stromness and Kirkwall.

One of the good things about the crab fishery, is that unlike much of the rest of our seafood, it is landed all around the mainland and islands and is not concentrated to big ports. Much is caught using passive fishing gear by small-scale fishermen who are integral within their local economy and rural communities. Recently, a large amount of brown crab was exported abroad, with a big market in China, but the impacts of trade restrictions and Covid-19 may yet force the fishery to adapt its approach.

In terms of sustainability, the fishery is currently not optimally managed because there are no overall limits on the amount anyone can catch. There are few effort restrictions and unfortunately stock assessments estimate that brown crab has been overfished in recent years. If you’re picking yourself a crab, make sure it meets Minimum Landing Size restrictions – generally 150mm carapace width. The MCS Good Fish Guide rates them between 2-3 for Scottish fisheries.

Mackerel

Nearly a third of Scotland’s fish landings (by value) are mackerel. However, there remain massive issues about where this benefit lands, given the majority of mackerel quota is currently controlled by a few individuals, that roughly half of the mackerel caught by Scottish boats is landed directly abroad and that commercial interests have resisted attempts to encourage them to land more in Scotland. Hopefully this will not continue through the COVID-19 crisis.

They are delicious, and whether you eat them fresh, smoked or even as sushi, they are extremely good for you. In fact, Scottish dietary guidelines say you should be aiming for one portion of oily fish (like mackerel or herring) each week.

We haven’t mapped the landings to foreign ports (although you can view the overall Scottish mackerel landings by value from 2015 here) but below you can see that, whilst the main ports dominate the landings – 56,000 tonnes to Peterhead, 14,000 tonnes to Lerwick – each year a couple of tonnes land to Scrabster, Eyemouth, Ullapool, some of the small port towns on the north Aberdeenshire coast like Portsoy and Rosehearty, even to Pittenweem on the Fife coast. This happens especially during the summer when shoals of mackerel head in to the coasts. Much of this has typically been used for baiting creels (shellfish pots) for crabs, lobsters and langoustine.

The Good Fish Guide has it rated green and green/amber throughout our seas – and, though there are some issues to do with overfishing in the big pelagic fishery, hand-lining is all green rated.

Saithe (Coley)

Saithe, otherwise known as Coley, is one of our favourites. Saithe is a gadoid, in the same family as cod, but it’s generally smaller, less meaty and a bit bonier. Because of this it’s never been as popular but don’t let that put you off; it’s great, especially when fresh.

Most saithe/coley is caught by the demersal trawl fleet, often the same boats catching your cod or haddock. We’re just coming out of the breeding time so aim for bigger fish – minimum size is 35cm, but anything above 60cm is mature so had chance to spawn.

Despite there being some concerns about trawling causing damage to the seafloor and other species being accidentally bycaught and discarded in this fishery, all the coley fisheries around Scotland are rated green or green/amber by the MCS Good Fish Guide

Here’s where they’re caught and where they are landed. There is a concentration of landings to the big ports of Peterhead, Lerwick and Kinlochbervie but Scrabster, Ullapool and Mallaig all have several tonnes worth of fish landing there each year. The fishing grounds are concentrated in the north North Sea and along the ‘Hebridean Shelf’, a steep underwater cliff edge to the North of Lewis.

Report highlights illegal discarding in scampi industry

We have published a ‘Discard Dossier’ in collaboration with Our Fish providing evidence that illegal discarding continues in the Scottish prawn (scampi) fishery and is threatening the recovery of our already collapsed fish stocks.

Here’s the executive summary:

In 2013 the ‘discard ban’ or Landing Obligation was agreed to reduce and record the amount of fish killed as ‘unwanted catches’ in our fisheries, specifically to end seafood waste at-sea and reduce the amount of unintended fish mortality caused to populations of fish caught as bycatch.

On the West Coast of Scotland, these populations include cod, whiting and haddock, all of which are at depleted levels in this area. Cod stocks have essentially collapsed.

The discard ban was phased in between 2015 and 2019 to allow fisheries and businesses time to adapt. However, a 2018 House of Lords investigation found “no evidence that fishers have been complying with it”, and further that “little attempt appears to have been made to enforce the landing obligation’s requirements thus far”.

Due to the depletion of fish stocks and consolidation of quota, the west coast fisheries now [Read more…]

Transparency is a fundamental tool for deterring illegal fishing

Earlier this week, the Herald ran a front page story ‘Justice in secret for skippers that flout laws at sea’. 

The news article focussed on concerns raised after the Scottish Government declined to disclose the identity of vessels given fines for suspected illegal trawling inside Loch Gairloch, an area of inshore seabed known to hold vital habitat for spring spawning herring. 

This is an issue we have been following for some time. Reports of illegal fishing in protected areas of Scotland’s seas are sadly all-too-frequent and despite increasing awareness of the problem, it’s still happening. This is in part due to the under-resourcing of fisheries enforcement in Scotland, but also because the legislative regime itself does not effectively deal with – and deter – illegal fishing. Sustainable fishermen, and our environment, are now paying the price:  illegal dredging or trawling can entail huge collateral damage to marine wildlife and also compromise the sea’s productivity for other fisheries. Back in 2018, we collaborated with local divers to investigate the seabed after reports of illegal trawling in Loch Gairloch. In July this year, the Scottish Government confirmed that two vessels were issued ‘Fixed Penalty Notices’, each for £2,000 for illegally fishing inside the Gairloch closed area. [Read more…]

A lesson from Loch Carron

What happened in Loch Carron is a window into the bright future that could exist along our coastline and a lifeboat moment for sustainable fishing in Scotland. It shows what can be achieved with popular will, local support and political leadership – that the guardianship of our seabed for future generations is possible, and is a good thing for coastal communities.

On Friday 17th May, a diverse group including local fishermen, divers, marine scientists, school children, campaigners, and a local politician, gathered in Plockton to celebrate Loch Carron becoming a permanent Marine Protected Area. Some literally gathered in Loch Carron itself, snorkelling and diving to see first-hand what lies below the waves.

Dredging in the dark

The success of Scotland’s seafood sector relies upon a reputation of high-quality, sustainable and traceable fish, and yet the Scottish Government is continuing to sit on its hands in the wake of repeated instances of illegal scallop dredging. We document a recent incident of suspicious fishing activity in the Sound of Mull, and explain how inaction by the Scottish Government is undermining the recovery of our marine environment – and why vessel tracking could help solve the problem.

Ram-raiding MPAs

In recent weeks, community organisations, fishermen and environmental groups have spoken with one voice to highlight the systemic failure by Marine Scotland to effectively manage Scotland’s inshore fisheries and protect and enforce fishing rules in Marine Protected Areas (MPAs). A series of incidents of both damaging and illegal scallop dredging prompted 42 organisations – including our own – to sign a joint letter to First Minister Nicola Sturgeon calling for the Scottish Government to enforce fishing laws in MPAs and rethink the lack of management, which currently leaves 95% of Scotland’s inshore waters open to scallop dredging.

Our view is that without improved management, the productive potential of our seabed will continue to be eroded by poorly regulated dredging. This means coastal communities, businesses and our broader inshore fishing sector are being disadvantaged by a degraded marine environment. [Read more…]

Open Seas statement on illegal and damaging dredging in Gairloch

Scallop dredging pulverises our seabed, and yet it is permitted through about 95% of our coastal seas. What we have seen in Gairloch are the actions of a few greedy fishermen, for whom 95% of it is not enough. These scallopers have decided to decimate one of the few small areas protected from this damaging form of fishing.

We need to get this fishery out of our sensitive and vulnerable coastal sea, unless in areas where the fishery can itself prove it is sustainable for it to be there. We also need to establish a proper means of tracking the boats so that illegal fishing like this is stamped out for good.

The blame in this instance lands firmly with Scottish Ministers. The current regulation of scallop dredging is pitifully inadequate. This Government is failing to protect our natural heritage by allowing one of the only places where herring are still spawning to be destroyed in this way. Unless they take action soon, they will be turning their back on not only our marine environment, but the future of our fisheries and the rural economy in places like Wester Ross. Real stewardship of our seabed would be to the long-term benefit of Scotland.

In just four years, scallop landings in Scotland have declined by roughly 30% (2013-2017). There is an underlying problem that needs to be addressed urgently.

For more information and background to this issue, read ‘Probe into alleged scallop dredging in protected area‘.

We will continue to update our own news page with more detail.

Scallop dredging: eco-label the problems away

Open Seas statement on scallop dredging ecolabel decision

Yesterday (20th June 2018) the Marine Stewardship Council (MSC) rejected our objection to the re-certification of the Shetland scallop dredge fishery. As a result, the MSC will now permit the fishery to sell dredged scallops using its blue tick label, despite the dredge fishery continuing inside Marine Protected Areas (MPA) and on other areas of sensitive habitat.

We think the decision, and the way the MSC have gone about making it, highlights a systemic failure in the MSC’s certification processes, and not only undermines the recovering health of our marine environment, but also shows that what MSC consider to be ‘sustainable’ is out of step with what the Scottish [Read more…]

Grey fish: Scotland’s seafood traceability problem

The recent incident of illegal dredging in a Scottish MPA has exposed a serious problem for producers and consumers of Scottish seafood, highlighting that we don’t know, with any geographical accuracy, where much our seafood comes from. Our follow up investigations suggest that legally and illegally caught fish and shellfish is being sold alongside one another, with buyers unable to distinguish legal catches from illicit ones. With increasing consumer demand for sustainable food with assured provenance and traceability, this article explores how improved vessel monitoring can solve the pressing problem of “grey fish” – fish of no proven origin – in our supply chains.

On Friday 25th January, two scallop fishermen – Davy Stinson and Steve Barlow –  hand-diving for King scallops off Scotland’s west coast, encountered evidence of damage to the seabed consistent with scallop dredging. The divers saw the tracks of scallop dredges on the seabed and a trail of broken scallop shells. The shells were cracked open, containing the scallop flesh, or ‘meat’, still inside, indicating that the damage had been inflicted recently (seabed scavengers, like crabs and lobsters had not yet moved in to eat the dying shellfish). Dredge damage is unfortunately not an unusual sight, but this damage was witnessed inside a Marine Protected Area – and also a Special Area of Conservation, designated under EU law – where scallop dredging has been banned since 2007.

Open Seas Evidence Behind Scallop Dredge Certification Concerns

We recently voiced our concerns about a seafood eco-labelling process for a scallop dredge fishery and have been publicly criticised for doing so. Polarised debate is clearly not in anyone’s interests, but we take accusations about our use of evidence and accuracy very seriously, and so here lay out our evidence and the reasons why our concerns remain accurate and valid. [Read more…]

Eco-labelling concerns for dredged scallops

Open Seas’ mission is to promote more sustainable fishing in Scotland. It is with some regret that we are now challenging the proposed re-certification of the scallop dredge fishery in Shetland.  Unfortunately the possible re-certification of scallop dredging here, under its current management regime, risks green-washing an important certification standard that should represent a benchmark for sustainability.

Scallop dredging is one of the UK’s most damaging forms of fishing. Dredge boats tow heavy rakes with metal teeth several inches long that dig into the seabed, dredging out the scallops. In April of 2017 the severity of damage caused by scallop dredging was revealed when a vessel towed through a well-known flame shell reef in Loch Carron. The killing of species other than scallops and the flattening of seabed habitats, means dredging has and continues to have a profoundly negative impact on the health of our seas. However, it does not have to be this way. Dredging in some [Read more…]
