The Price of Fish – A Video Interview with Wildlife Pathologist Vic Simpson

Published

on

Intro by Jeff Goodman:

For me, one of the pleasures of diving is the journey to the dive site. Watching out for dolphins that may come to look at the boat, or the sea birds purposefully heading along the coast to some secret fishing ground. Watching gannets streamline their bodies as they plummet out of the sky into the water or the miniature auks duck-diving to safety as the boat approaches. The cormorants and shags that glide gracefully across the water with a small fish in the beak. Then, on very rare occasions, one of these magnificent birds will pass by you underwater ensuring the topic of your conversation when getting back to the surface.

Hundreds of thousands of sea birds die each year in fishing gear. These are staggering figures and are probably a huge under-estimation so it seems a marvel that any survive at all when you also consider the loss of breeding habitat and an increasing shortage of food. The issue of ‘accidental’ bird mortality is a global issue but happens throughout the world at local levels. A recent case was near my home in Cornwall where 26 cormorants, shags and guillemots, were washed up on the shore in Falmouth after what is now surmised as being caught and drowned in local fishing nets. For any air breathing animal, drowning and struggling for life while being held underwater must be a true horror. It is something we all fear and yet we willingly and constantly subject other species to this painful death in the name of our dietary desires.

The birds were taken for autopsy to Vic Simpson, one of the world’s leading wildlife pathologists. This short video clip shows Vic working with scientific rigour as he highlights some of the processes that will determine the cause of death. But even such an experienced scientist as Vic feels the frustration and despair of providing the information needed to help understand our wildlife and the inability of people to implement this into more wildlife friendly methods of fishing.

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%
