In 2005, the University Marine Biological Station Millport began an in-depth study of Basking Sharks in the Firth of Clyde and adjacent areas in SW Scotland.
The aim of the project is to get a better estimate of the number of Basking Sharks using the area and to gain a more complete knowledge of their annual movement and behaviour.
To do this, we need your help by reporting any sighting of Basking Sharks.
Information on visual sightings of sharks will be invaluable in helping us assess the status of our Basking Shark population.
We would also welcome sightings of dolphins, porpoises and whales within the same area.
A progress report on Project Basking Shark and the Clyde Cetacean Monitoring Programme in 2006 is available.
Key Facts on Basking Sharks
- Found in temperate coastal waters
- Filter feed on zooplankton
- 10-11m long and 5-7 tonnes
- 2nd largest fish globally after whale sharks
- Live up to 50 years
- Only give birth every 4 years after a 1-3 year pregnancy
- Vulnerable to exploitation
- Targeted for their fins
- Listed by IUCN Red List as Endangered in Scotland
Fin identification
One of the best ways to recognise individual Basking Sharks is by comparing photos of the sharks, their fins in particular.
Nicks and scars can characterise individuals.
If you have a good photo of a Basking Shark fin, we might be able to match it up and identify the shark.
Have you seen one?
The project follows the sharks throughout the year. Any information on sightings of sharks will be invaluable in helping us with this work.
If you see a basking shark, dolphin, porpoise or whale, please note down the following:
- date
- time
- location
- estimated length
- swimming direction
