Microtagging cultured lobsters, Homarus gammarus (L.), for stock enhancement trials

Abstract. The adaptation of proprietary fish-tagging equipment for tagging small lobsters, Homarus gammarus (L.) (9–15mm carapace length), with internal microware tags is described. Tag retention was 85–100% as the animals grew through up to 22–29 moults (90–102mm carapace length) in captivity. Claw loss during handling was reduced from 4% lo less than 1% at a tagging rate of 240 lobsters per has experience was gained.
