The behaviour of Norway lobster towards baited creels and size selectivity of creels and trawl

摘要

The behaviour of Norway lobster (Nephrops norvegicus L.) towards baited creels was studied byunderwater television at three different localities. A typical nocturnal activity pattern wasobserved. Most of the individuals approached the creel up current. The general behaviour in thevicinity of creels and lobster burrows is shortly described. The creels were found to have a fairly lowcatch rate, being less than ten per cent of the observed individuals. Catches of Norway lobster bycreels and trawl have distinctly different length distributions. The possible reasons for this are discussed.
