Length–weight relationships of forty-nine fish species from shallow waters of Gökçeada Island, northern Aegean Sea

Length–weight relationships (LWRs) of fishes provide important information for many studies in a given geographic region, such as comparing the condition, fatness, estimation of weight-at-age from total reported catch weight, and length–frequency distributions (Tesch, 1968), as well as for interregional life-history comparisons (Petrakis and Stergiou, 1995). The relationships may change temporarily and/or spatially, and for this reason should be regularly updated (Ismen et al., 2007). The northern Aegean Sea is an important region for fisheries; fish stocks are heavily exploited by artisanal and industrial fishermen. Although length–weight relationships of many fish species have already been determined fro
