New report takes stock of jellyfish in UK seas

Published

on

A new report by the Marine Conservation Society (MCS) and the University of Exeter takes stock of where and when UK jellyfish occur in UK seas for the first time in over 40 years.

The report, published in the Journal of the Marine Biological Association, details over 5000 reports of jellyfish sightings of eight different species sent to MCS by the British beach going public between 2003 and 2011 for their MCS National Jellyfish Survey.

The survey is the largest of its kind in the UK and has been attracting a growing number of jellyfish sightings, with 2013 proving a record year when 1,133 reports were received. This year is also turning out to be good for jellyfish, with over 500 reports already received by mid-July, only halfway through summer months when most records are received.

Our survey puts jellyfish on the map in the UK. In this latest paper we show where and when these species now occur throughout UK coastal waters,” said Dr Peter Richardson, Biodiversity Programme Manager for the MCS, The last time the national picture was described was well over four decades ago, so this study provides a very timely update.

Prof. Brendan Godley of the University of Exeter said, “By taking stock of our jellyfish in this way, we provide an important baseline of information which will help us understand how jellyfish species react to environmental changes that influence our coastal seas, including climate change.”

The top five jellyfish species described in the report are summarised below.

Jellyfish species

Percentage of records

Distribution

Season (when most reports received)

Moon

29%

All around the UK

May to September

Compass

19%

Southern distribution (Merseyside to Norfolk)

June to October

Lion’s mane

18%

Northerly distribution (North Wales to Sunderland)

May to October

Blue

15%

SW England and Wales, NE England and Scotland

May to September

Barrel

10%

Hotspots in Welsh and Scottish waters

Reported throughout the year

The survey depends on the generous support of an army of over 3,500 jelly-spotting volunteers, who have been diligently sending in their sightings throughout the year every year since 2003. Dr Richardson says “Our paper shows that publicly driven, collective citizen-science can help us understand our environment on a scale that would otherwise be unaffordable.”The other species are the mauve stinger, Portuguese Man of War (close relative of jellyfish) and the by the wind sailor (also a close relative of jellyfish), which together make up approximately 10% of survey records and are not recorded every year.

This year MCS has so far received reports of seven of the eight species, including barrel, moon, blue, compass, lion’s mane, mauve stingers and by the wind sailors from around the UK. As the summer progresses we can expect to see many more jellyfish reported to the MCS survey, and so far barrel jellyfish have made up the majority of reports, with most of these reported from South West England and Wales.

“The remarkable number of barrel jellyfish reported from South West England this year is quite unusual, and at odds with what our report describes, previous years have seen hotspots for this species in West Welsh and Scottish waters,” said Prof. Godley, “We’re not sure why, but the very mild winter probably meant more adults survived at depth, which will have returned to the surface in spring as waters warmed up. This year’s strange barrel jellyfish results highlight the importance of running the survey year in and year out to track these unusual events and discover if they turn into trends”.

Dr Richardson said, “We still know relatively little about jellyfish, but given the economic impacts that large numbers of jellyfish can have on tourism, fishing, aquaculture and even power generation, we can’t afford to ignore them.”

Taking part in the jellyfish survey is fun and easy. The full-colour MCS jellyfish photo-ID guide can be downloaded from www.mcsuk.org, where jellyfish encounters can also be reported in detail online. Survey participants should always remember to look carefully at jellyfish before reporting them, but should not touch them as some species have a powerful sting.

Paul Watson Released as Denmark Blocks Japan’s Extradition Bid

Renowned anti-whaling activist Paul Watson has been released from custody in Greenland after spending five months in detention. Denmark’s Justice Ministry rejected Japan’s request for his extradition, citing insufficient guarantees that his time already served in custody would be credited against any potential sentence.

The 74-year-old Canadian-American was arrested on July 21 in Nuuk, Greenland’s capital, when his ship docked to refuel. His arrest was based on a 2012 Japanese warrant related to a 2010 encounter in Antarctic waters. Japan alleged Watson obstructed operations and caused damage to a whaling research ship during efforts to disrupt illegal whaling. Watson has consistently denied these claims, maintaining his commitment to marine conservation.

Denmark, which oversees extradition matters for Greenland, concluded that while the legal conditions for extradition were met, the lack of assurances from Japan regarding time-served credit made extradition untenable.

In a video shared by his foundation, Watson expressed gratitude and relief, saying, “After five months, it’s good to be out… and good to know they’re not sending me to Japan.” He added that the most difficult part of his time in custody was being separated from his two young sons.

Watson is a pioneering figure in marine conservation, known for founding the Captain Paul Watson Foundation in 2022 after decades of activism with the Sea Shepherd Conservation Society. His bold efforts to defend marine life have earned him widespread support, including from celebrities and conservationists. His work has also been featured in the acclaimed reality TV series Whale Wars.

Watson’s lawyer, Jonas Christoffersen, praised the decision, stating, “We are happy and relieved that Paul Watson is now free.” He added that Watson is eager to reunite with his family and continue his vital work.

The arrest occurred while Watson’s vessel, the M/Y John Paul DeJoria, was en route to the North Pacific with a team of 26 volunteers to intercept a Japanese whaling ship. His foundation described the arrest as politically motivated and emphasized that Watson’s actions were focused on ending illegal whaling practices.

Japan resumed commercial whaling in 2019 after leaving the International Whaling Commission, asserting that whale meat is a cultural tradition. Conservationists, however, continue to challenge these practices, highlighting their impact on marine ecosystems.

Despite the challenges, Watson remains steadfast in his mission to protect marine life and bring attention to whaling practices. His dedication to ocean conservation has made him a globally respected advocate for the environment.

12 Days of Zero-Waste Fish-mas

Published

marine conservation society

This holiday period, the Marine Conservation Society, the UK’s leading ocean membership charity, invites you to make some simple changes to eating fish this Christmas to help our seas.

Dr Kenneth Bodles, Head of Fisheries and Aquaculture at the Marine Conservation Society, said, “During the festive season, our consumption increases, but so does waste. Sustainability isn’t just about where food comes from – it’s also about how you use it. By reducing waste and making the most out of your seafood, you’re not only taking steps to be more ocean-friendly, but can also help to cut costs during what is often one of the most expensive times of the year”.

The Marine Conservation Society has compiled twelve tips on how to consume seafood sustainably with zero-waste this Christmas:

Buy whole fish instead of fillets

Instead of fillets, consider buying whole fish such as salmon, hake, or lemon sole. By adopting a “nose to tail” approach with cooking, whole-baked fish not only feeds a crowd, but also helps to minimise waste and maximise sustainability by using up every part of the animal, including bones, skin, and fat.

Make fish stock

Leftover fish bones or shells can be put to good use by boiling them to make a nourishing fish stock or bisque. This can be frozen and preserved for later use and makes for a flavourful base in a soup.

Make your own fish pâté

Avoid waste by turning leftover fish, such as smoked mackerel or salmon, into a delicious pâté by blending with cream cheese and lemon. Perfect when paired with crackers.

The sustainability of salmon and mackerel varies depending on where and how it is caught or farmed. For more information on green-rated options, check the charity’s Good Fish Guide.

Buy frozen

By purchasing seafood that is frozen or vacuum-packed, this helps to reduce waste by extending the shelf life of your food.

Fish pie

If you’re wondering what to do with leftover cooked fish, why not opt for a classic fish pie with mashed potatoes, leeks, and a cheesy sauce? A sure crowd pleaser on Boxing Day.

Use the head

Don’t forget the fish head! The meat is incredibly tender and flavourful. The charity recommends a cod’s head curry or recreating Fallow’s renowned cod’s head in siracha butter.

By stretching your ingredients further, not only is this a more sustainable way to enjoy seafood, but also cost-effective by repurposing leftovers and cooking creatively.

Boxing Day brunch

Mix leftover kippers or smoked salmon with scrambled eggs for a tasty, zero-waste, Boxing Day brunch.

For best choice, make sure you buy kippers, or herring, from the North Sea and the North Irish Sea.

Zero-waste storage

A top tip from the Marine Conservation Society to avoid waste is freezing fish offcuts to save for future use.

Crisp up the skin

Even leftover fish skin can be turned into a quick savoury snack by crisping it up in an air fryer with a little olive oil and salt.

Anchovies two ways

Leftover anchovies can either be blended with butter to make a delicious anchovy butter or tossed into pasta for a hit of umami flavour.

The charity recommends opting for anchovies caught in the Bay of Biscay for best choice.

Fishcakes

For an easy, zero-waste meal, leftover seafood trimmings can be mixed with mash and fried in breadcrumbs to make fishcakes.

Pickled mussels

Try pickling mussels in 1:1 vinegar and water, with a dash of sugar for a sustainable, zero-waste snack that can be enjoyed well beyond the festive season.

Mussels farmed in the UK are a seafood superhero. Grown using low-impact methods and harvested by hand, they get all the food they need from the sea around them. This makes them one of the most sustainable, ocean-friendly, and cost-effective seafood options.

Players of People’s Postcode Lottery have raised £6.6M towards the Marine Conservation Society’s vital work in making seafood more sustainable.

Laura Chow, Head of Charities at People’s Postcode Lottery, said: “Fish is a festive favourite for many, but making sustainable choices when it comes to how we buy and eat seafood makes all the difference for our ocean. Support from players of People’s Postcode Lottery has helped the Marine Conservation Society further its sustainable seafood work, so that we can all enjoy healthier, better protected seas.”

The Marine Conservation Society encourages you to make sustainable seafood choices a year-round habit, not just for Christmas. To check how sustainable the seafood on your plate is, you can visit the charity’s Good Fish Guide. The Guide helps consumers and businesses identify the most sustainable seafood using a simple traffic light system, based on where and how species are caught or farmed. Green is the best choice, amber means improvements are needed, and red indicates fish to avoid buying.

Zero-waste gift idea

Why not embrace a zero-waste Christmas by gifting a membership to support marine conservation? It’s a meaningful, low-waste gift that helps protect our ocean for generations to come. Memberships start from as little as £5 a month – the price of a sandwich and drink from your local coffee shop.
