Preliminary biological data on pomadasys incisus (osteichthyes: Haemulidae) in the aegean sea, Greece

Abstract

The present paper gives, for the first time, some biological data concerning Pomadasys incisus in the Argolikos Gulf (C. Aegean Sea). The bastard grunt (Pomadasys incisus) is a thermophilic species well adapted in the above area, but the status of fishery suggests an overexploitation. The sex ratio was in favour of males. The length frequency distribution did not differ between the sexes. Growth in weight was estimated by means of the length-weight relationship. Reproduction seemed to take place in summer. Certain morphometric characters appeared to be useful while comparing populations among the different populations in the Mediterranean.
