Length-Weight Relationships of Fishes from Gökova Bay, Turkey (Aegean Sea)

Length-weight relationships (LWRs) are presented for 17 fish species caught from Gökova Bay (southeastern Aegean Sea) during the 2006 fishing season. Fish samples were collected from small-scale trammel nets and longline fisheries. The values of b ranged from 2.086 (±0.152) for Sphyraena sphyraena to 3.499 (±0.058) for Scomber japonicus. The median value of b was 3.055 (±0.081). The r2 values ranged from 0.712 for Sphyraena chrysotaenia to 0.996 for Scomber japonicus and all relationships were highly significant (P < 0.001). Estimated LWR parameters of 4 species, Dicentrarchus labrax, Seriola dumerili, Siganus luridus and Sphyraena sphyraena, for Turkish waters are presented for the first time.
