Length–Weight Relations of 34 Fish Species Caught by Small-Scale Fishery in Korinthiakos Gulf (Central Greece)

Abstract

Length–weight (L–W) relations are presented for 34 fish species covering a full annual fishing period (231 fishing days) of professional small-scale fishery in Korinthiakos Gulf during 2008–2009. These were the typical fish species caught by Greek small-scale fishery. Mean annual values of b ranged from 2.751 to 3.704. The L–W relations were positively allometric for 12 species, negatively allometric for seven species and isometric for 15 species. Twenty-two out of 66 species-season combinations showed that the intercept a and/or slope b values differed significantly among seasons. For Greek waters no information regarding the L–W relations existed for three of the 34 recorded species (i.e., Dentex macrophthalmus, Trachinotus ovatus, and Scyliorhinus canicula).
