Resilient shoots – catches triggerfish
The white fish trawler Resilient (LK 195) had an oddity among its catch during a recent fishing trip off Fetlar.
The vessel, skippered by Arthur Polson, trawled up a grey triggerfish, normally a denison of warmer seas including tropical and sub-tropical waters off west Africa and the Mediterranean.
Grey triggerfish (Balistes capriscus) are being recorded around Britain in increasing numbers, especially around the south and west, but there have been only six caught in Shetland waters in the last 20 years.
North Atlantic Fisheries College took custody of the unusual visitor which normally lives on rocky sea-bed in relatively shallow water less than 100m deep, and also around floating objects, and are not strong swimmers.
Their main food is hard-shelled prey, such as crabs, molluscs, sea urchins, and starfish.
