Today marks Endangered Species Day and we thought we'd introduce you to some of animals that we are working to safeguard. Meet Juan, or the Juan Fernandez Mackerel as he's known officially! He is one of many hundreds of species of fish that live in the Western Indian Ocean, a region that is heavily impacted by human activities including overfishing, pollution and habitat degradation.

Rob, our IUCN Red List Officer has been collecting data and working with experts to assess the fishes of this ocean. What is important about Juan was that him and his species were assessed as VULNERABLE meaning that they are facing a high risk of extinction.

By identifying this, Rob and other experts have taken the first steps towards changing the future for this species. This is what the IUCN Red List of Threatened Species is all about and we proud to be working with them to make a real difference.

Our partnership with IUCN has proven so effective and popular, other zoos and aquariums across the world also joined forces with the IUCN in 2018. They are all now doing their bit to save species from extinction too. As part of his role, our Red List Officer helps to train, guide and support these new partnerships, growing an international team of Red List Officers all contributing to the important work of the #RedList.

Over 300 guests from the process, renewable, engineering and energy industries attended the CATCH / YCF Annual Awards Dinner last night. This was the first event that the two organisations have held together, since their merger in 2018, and in a new category the Humber Waste Alliance won CATCH / YCF Best Partnership Award.

This special award celebrates a new initiative presently involving 35 organisations including The Deep. The Humber Waste Alliance aim to reduce waste to prevent marine little polluting the Humber. The group has a strong desire to improve individual credentials and aspire to lead the region as an area of excellence.

Current initiatives the group are promoting include replacing products with eco-friendly alternatives, being advocates for changing practices in organisations and working with environmental groups to understand new threats to our water ways to name but a few. The group has over 35 members and growing regularly all with a strong objective to reduce waste amongst their businesses and have over the last 11 months, grown momentum to protect the Humber for the future.

Tina Raleigh, ABP and current chair says “It’s fantastic that the Humber Waste Alliance have received this award. All of our members are dedicated in working to improve the environment on the Humber, so to receive an accolade like this really proves that collaboration is the key to success.”

Further initiatives are planned this year including a recycle sculpture promoting the group to be displayed in the shopping centres over the summer and waste conference in November.

At the end of 2018, Deep Aquarist Shoshana helped to rehabilitate cold stunned sea turtles at the New England Aquarium Rescue Centre. Located on the East Coast of the United States, in Boston Massachusetts, the centre took in over 400 cold stunned turtles during November and December.

While Shoshana’s involvement may be done for this season, the centre is still very busy caring for the turtles to get them ready for release in the coming months. One of these is number 266, dubbed Munchkin by the rescue staff, it is the largest loggerhead to come through the centre, weighing 300 pounds (136kg). 

Connie Merigo, Rescue Department Manager at the New England Aquarium has told us that 266 has regained enough weight to fill out and now physically looks like an adult Loggerhead. Following the completion of a few more tests, we keep our fingers crossed that she will be released later in the year.

Staff from the New England Aquarium Rehabilitation Centre will also be departing soon for the warmer waters of Florida. Travelling in a climate controlled SUV they will be transporting at least one Loggerhead and ten Kemp’s Ridley turtles to release them into the ocean on the 22nd April - marking the moment for World Earth Day.

With many still under care at sites across the US, the final numbers for release this year are yet to be confirmed. Committed to continuing our support for this project, we will continue to follow up with Connie and her team over the coming months, with a final summary of the season’s success revealed later this summer.

Behind the scenes our Aquarists not only work to conserve the large animals, but the smaller, lesser known creatures too. These little killifish are an endangered species. Isolated to the remote lakes in Madagascar, they can be found nowhere else on the planet. 

A pink-tinged, rounder tummy is a sign that a female is gravid (has eggs) and is ready to mate, so our team have created separate nursery habitats to offer a safe and robust spawning site. They have developed small floating blocks, complete with with thick cotton tendrils that trail deep into the water column to act as artifical spawning site. These replicate the root systems of floating plants – a preferred egg laying spot for this species. When ready, a male is introduced for spawning to take place.

After a couple of days, the female is removed and the eggs left to incubate. With continued monitoring and water care, the eggs will hatch after just a few weeks. Despite only being millimetres in size, they are fully independent.These habitats will act as a nursery until the juveniles are big enough to move into the main display.

The Deep is working with ZSL London Zoo to raise more awareness around the importance of killifish to their natural range, with an aim to help safeguard them for the future.

The Deep has donated £750 towards a new children's book by our friends at Galapagos Conservation Trust.

The book follows Marti the Hammerhead shark as she embarks on her migration between Galapagos and Cocos island, Costa Rica. During her journey, Marti has to navigate the dangers posed to marine life, meeting friends along the way as well as the scientists that are working to protect her migration route.

The book has been made possible through a crowdfunding campaign and after reaching the target amount of £7,500, the charity will be able to fulfil their goal of distributing the books into every school in Galapagos. This, alongside community events for local families, will help to engage young children with marine conservation, which is so vital for the unique islands they call home.

The Scalloped hammerhead shark, along with many other shark species native to the islands, is classed as Endangered on the IUCN Red List. They are increasingly targeted by commercial and illegal fisheries for their fins as these are highly valued in the Asian market for shark fin soup. They are also very vulnerable to being caught as by-catch by trawls, purse-seine nets, gillnets and longlines. By raising awareness and using tagging technology, the hope is to create a protected swimway for the hammerheads so their migration route is safe from these threats.

The Deep has been working with Galapagos Conservation Trust since 2014 when they became the first recipients of funds from Project Penguin, an inititive by The Deep to contribute to worldwide penguin conservation. To this date the Deep has donated £25,000 to GCT who are working to conserve the Galapagos penguin, the rarest penguin species in the world.

You can get your fins on a copy of 'Marti the Hammerhead Shark' from The Deep’s gift shop when the first edition is printed in the summer.

You can follow the project here.
