The study focuses on some reproductive and behavioural aspects of N. norvegicus in the northern Tyrrhenian Sea. Berried females were very abundant in autumn-winter; these specimens increase their burrowing behaviour in this period. This means a shift of the sex ratio towards males in the trawl catches. The size at first maturity for females was 27,1 mm carapace length.

Abstract
The study focuses on some reproductive and behavioural aspects of N. norvegicus in the northern Tyrrhenian Sea. Berried females were very abundant in autumn-winter; these specimens increase their burrowing behaviour in this period. This means a shift of the sex ratio towards males in the trawl catches. The size at first maturity for females was 27,1 mm carapace length.File in questo prodotto:
