Divers ask to take part in Easter Egg Hunt with a twist!
Stuck for ideas on what to do over the Easter Holidays? Want to get outside and do something fun to work off all that chocolate? Want to get closer to nature? The Shark Trust has an Easter Egg Hunt with a difference for you to try. Take part in the Great Eggcase Hunt and get involved with a big citizen science project that helps shark and skate conservation.
2023 marks the 20th anniversary since the Great Eggcase Hunt began. To celebrate this monumental milestone, the Shark Trust has launched a new app that features the Great Eggcase Hunt along with four other citizen science projects to take part in. Through these projects, anyone with an interest in sharks, skates and rays can contribute to valuable research by submitting your eggcase finds or shark sightings – while unlocking collectable shark cards as you build your logbook of finds.
Senior Conservation Officer Cat Gordon says “We’re really excited to be celebrating the Great Eggcase Hunt’s 20th anniversary this year! The project has evolved so much since it first began back in 2003. We’re now well on our way to receiving half a million eggcase records!”
New finds from around the world are regularly being added to an ever-growing database. The project now has an impressive 446,000 eggcases recorded from a total of 49 species documented from 30 countries.
Cat goes on to add “One eggcase find may not seem that significant on its own, but when all of this information is brought together it can help us better understand species presence and diversity. It’s also a great way to get involved in shark conservation, and of course, it’s fun – and not to mention competitive!”
Last year saw over 51,600 eggcases recorded in total, and 2023 has got off to a flying start with 22,400 eggcases already recorded since January! It looks set to be a bumper year. During last year’s two-week Easter holidays, we had 7,560 eggcases recorded – this Easter we’re on a mission to keep up momentum and beat the number of submissions! The Shark Trust are hoping that divers will increase the number of in-water sightings in the database this year too.
So, what actually is an eggcase? Some sharks, and all true skates, reproduce by laying eggs. These are surrounded by a tough leathery capsule that protects the embryo as it develops inside. Small slits in the eggcase allow fresh oxygenated seawater in, and let waste out, while a yolk sac provides plenty of nutrition. After several months (although this will vary depending on species) they are ready to hatch. The top of the eggcase will open and a fully formed shark or skate will emerge and be completely independent, having to fend for itself. Once empty, the eggcases (or mermaid’s purses) often wash up on the beach.
You don’t need to be part of an organised event to join in with an eggcase hunt (although check with your local marine centre or aquarium to see if there is one running near you!). All you need to do is head to your nearest beach, or go diving, and take a look around to see what you can find. The best places to search are in the strandline where seaweed and debris washes up, and in sand dunes at the back of the beach as they often get trapped in the grass. Underwater look closely in the seaweed.
The eggcases of different species vary. So, once you’ve found an eggcase, look at the size, shape, and features to identify which species it belongs to – we’ve developed identification resources to help you figure it out! Once you’ve got your answer, head over to the Shark Trust’s Recording Hub or use the new citizen science app to submit your finds.
The Shark Trust is continuing to add to the project’s resources by developing regional identification materials, collaborating with additional partners, and will soon be releasing a series of videos to help those who want to take part in the project and become Eggcase Champions – so watch this space for further developments.
Paul Cox, Shark Trust MD, said “The Great Eggcase Hunt makes for a fantastic family day out at the beach. Once you spot your first one, you’ll find it hard to stop! So get involved with shark conservation and have fun too!“

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
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.
