LIFE HISTORY TRAITS OF HOPLOSTETHUS MEDITERRANEUS (PISCES: BERYCIFORMES) FROM THE NORTH-WESTERN IONIAN SEA (MEDITERRANEAN SEA)

摘要

The fish Hoplostethus mediterraneus is a bycatch of the deep-water trawling in the north- western Ionian Sea. Data on its life history traits were collected during twelve trawl surveys carried out at two month intervals, between August 1993 and July 1995. A vertical distribution according to size was observed for this species. The year's young were recruited mainly during the spring-summer period. Sex-ratio changed by size with females larger than males. Mature specimens were found mainly between May and November with a reproductive peak during late summer.
