Trigger fish tagging programme

trigger fishThe grey triggerfish which has long been considered a seasonal visitor to the British coast but in the Western Atlantic it is found from Bermuda to Nova Scotia.

This has led researchers to start asking the question “is it possible triggerfish are seasonal migrants not just visitors?”

There is precedent for this: Until recently it was thought that occasional leatherback turtles seen around the west coast of Britain were lost but recent research has shown they conduct visits to feast on the abundance of jellyfish around our west coast in summer.

A second question is “is it possible triggerfish have started breeding in our coastal waters?”

To answer these questions, researchers have started a volunteer triggerfish monitoring programme. Triggerfish are caught by local anglers and tagged with a T-bar tag on the main dorsal fin (not the fin with the trigger). If these fish are re-caught the tag number and location where they are caught can be reported by clicking on the Reporting Form link in the side bar or here

How can you help? Currently there is very little information regarding Triggerfish in British coastal waters any information about their movements is valuable so the researchers would like reports of any sightings of triggerfish to be reported via the Reporting Form here.
