St Helena National Trust launch Whale Shark ID App

Published

on

Whale sharks are found in tropical oceans all over the world. In St Helena’s Island’s Marine Protected Area, (nearly the size of France), the Whale sharks – locally known as Bone sharks, are the only known population where an almost equal number of both mature male and female sharks come to feed and recuperate.

As part of the St Helena National Trust’s annual bone shark research, the Marine Team documents and observes behavioural encounters of individual bone sharks throughout the season. The data collected over time, together with historical island data, creates a clearer picture of how many sharks migrate to the island every year, when and where they visit, and just maybe… to discover if they come here to breed.

Over the years, it has increasingly became evident that one of the island’s premium tourism attractions is the Bone Shark, and Trust Marine Team has been progressing a number of initiatives which are focused on promoting the Island as the No.1 destination for both research and visitor experience in relation to these “gentle giants”.

“With St Helena’s Fibre Optic Cable Project advancing, new technology being introduced and the majority of the population owning a mobile phone, our island has started a new digital age and because of this, we are so proud to be able to launch our brand new, ‘St Helena Whale shark ID App’” says Marine Research Coordinator, Kenickie Andrews.

In collaboration with app designers, CRITTER, (funded by Blue Marine Foundation and Enterprise, St Helena), the Trust Marine Team has been working this mobile app for over a year. Found both on Apple App store and Google Play store, the new, free app allows anyone to submit their bone shark sightings and encounters to the Trust, contributing to an important effort to further understand these secretive and endangered marine species.

“Our app enables not just the Marine Team, but, also our local citizen scientists, enthusiasts, visiting tourist and members of the public to contribute to local bone shark encounter data, track individual sightings, and learn more about our Islands unique marine megafauna in the palm of their hand”, continues Kenickie.

“For environmental projects such as this, high quality on going field research is an incredibly important tool and the data collected, helps local researchers such as our team to maintain an understanding of the current demographics of our bone sharks, who and where have the sharks been and how long are they here for. When we can understand why these sharks come to the Island, their behaviours and what they do here, we can do more to better protect them and help identify management objectives to ensure that the world biggest fish remains safe”.

The app allows the user to also keep up with all recent shark encounters found, learn more about the individuals that the user has submitted via their own user portal and or others that have been found, displays of an island map to discover the teams research and sighting hotspots of the season, document behaviour observers and injuries and using their uploaded ID photo of the sharks, help to identify any sharks, possibly new to science or those that have returned back to the Island.

Through this input, the Marine team can review and monitor all encounter data submitted via the main app portal to help inform the research conducted and directly support the well-being of our visiting shark population.

Do you have a moment to help protect our oceans?

We’re on a mission and have partnered with DIVE PROJECT CORNWALL to help protect our oceans for future generations to cherish and enjoy.

DIVE PROJECT CORNWALL is a unique EDUCATION and EXPERIENCE initiative, reaching over 3,000 schools with their Ocean Education Programme, inspiring the next generation to protect our oceans for everyone to cherish and enjoy.

At the heart of the project is a competition for 400 lucky teenagers to win the EXPERIENCE of a lifetime. They will take the learning from the classroom straight to the shores of Porthkerris on a 6-day, life changing trip where they will learn to scuba dive and be taught the importance of marine conservation. They will become ‘Ocean Influencers’ for the future.

DIVE PROJECT CORNWALL needs our help.

Can you join us with a gift to DIVE PROJECT CORNWALL?

Whether it’s £5 or £50, a gift from you to the DIVE PROJECT CORNWALL Crowdfunder Project will help their vision of protecting our oceans through the innovative experience designed for school children.

Will you join us and pledge to support 400 lucky teenagers learn from and EXPERIENCE the ocean like never before and give them an EDUCATION they can use to inspire others, not forgetting the memories that will last a lifetime?

For more information, you can read the DIVE PROJECT CORNWALL story HERE.

Help us create the next generation of Ocean Influencers with a donation to DIVE PROJECT CORNWALL and ensure our oceans (and planet) are protected for the future.

Spring jellyfish blooms bring turtles to UK shores

Marine Conservation Society’s wildlife sightings project asks beachgoers to share their discoveries and contribute to research

The Marine Conservation Society’s long-running wildlife sightings project focuses on two key species which arrive on UK shores: jellyfish and, as a result, turtles. Both species are vital in supporting ocean biodiversity and are indicators of climate change while being at risk from its impacts.

The charity is asking beach and seagoers to share when they spot either of these marine animals to support ongoing research.

During spring and summer, jellyfish arrive in the UK’s warming waters to feed on plankton blooms or, in fact, anything small enough to get caught. To that extent, jellyfish feed not only on plankton, but also the array of eggs and larvae of fish, crustaceans, starfish and molluscs which rely on plankton as a stage of reproduction.

With healthy fish stocks and rich biodiversity, jellyfish quickly become part of an effective food chain. Everything from tuna to turtles will feed on jellyfish of various sizes, so the population is well controlled. Supported by a rich and diverse ocean ecosystem, jellyfish link the microscopic world of plankton to larger marine animals and the ocean around them.

Jellyfish are especially appealing for marine turtles. Six of the world’s seven marine turtle species have been spotted in UK seas as a result of jellyfish blooms in spring and summer.

The largest sea turtle, and the most common in UK seas, is the leatherback which has a ‘vulnerable’ conservation status. Reporting sightings of these incredible creatures will support the Marine Conservation Society and others in understanding their movements, potential threats and how to better protect them.

Amy Pilsbury, Citizen Science Project Lead at the Marine Conservation Society, said:“For more than 17 years, beachgoers across the UK have been contributing to scientific research by sharing their wildlife sightings with us. It’s a key part of our work and plays a vital role in better understanding and protecting our ocean.”

In 2014, with partners from the University of Exeter, the Marine Conservation Society published the first paper from the survey data, confirming key information about UK jellyfish and including the first distribution maps of the surveyed species.

Since the 2014 paper, the wildlife sightings project has recorded notable events such as massive and extensive annual blooms of barrel jellyfish and several summers of Portuguese Man o’ War mass strandings.

The charity continues to run its wildlife sightings project to see what happens to the distribution and frequency of mass jellyfish blooms over time. The data will help to explore any links jellyfish blooms have with big-picture factors such as climate change.

Jellyfish can be spotted year-round in UK seas, but larger blooms are more likely to appear in spring, lasting through until autumn. Jellyfish sighting records from 2021 suggest that compass jellyfish are the most common around UK shores, making up 36% of reported sightings.

Jellyfish species Percentage of sightings reported
Compass jellyfish 36%
Moon jellyfish 17%
Lion’s mane jellyfish 15%
Barrel jellyfish 14%
Blue jellyfish 9%
Portuguese Man o’ War 6%
Mauve stinger 2%
By the wind sailor 1%
