Fish by-catch species from coastal small-scale shrimp trammel net fishery in the Aegean Sea (Izmir Bay, Turkey)

Fish by-catch from coastal small-scale shrimp trammel net fishery was estimated from fishery-dependent surveys in Izmir Bay (Aegean Sea), Turkey, during the 2004 and 2005 fishing seasons. Sampling data were obtained from 170 observations onboard 18 commercial fishing vessels. Fifty-two species belonging to 31 families of fish, including cephalopods, constituted the by-catch. Diplodus annularis was the most abundant by-catch species followed by Loligo vulgaris > Sepia officinalis > Mullus barbatus > Boops boops > and Solea vulgaris. The estimated total ratio of fish by-catch to shrimp was 1 : 1.09 kg.
