Summary Length–weight relationships for 47 coastal fish species from Gökceada Island in the northern Aegean Sea, Turkey are presented. Samples were caught in depths of <30 m by gill and trammel nets between March 2004 and February 2005. The most abundant families were Sparidae (30%), Centracanthidae (19.9%), Serranidae (7.14%), Scorpaenidae (6.59%) and Labridae (6.09%). Estimates for parameter b of the length–weight relationship ( W = aL b ) ranged between 2.08 and 3.73. The mean b ‐value 3.03 ± 0.052 (SE) was not significantly different from 3. Significant differences between b ‐values were found between sexes for Boops boops , Diplodus annularis , Mullus surmuletus , Pagellus acarne , Sarpa salpa , Spicara maena and Spicara smaris and between seasons for Diplodus annularis , Mullus surmuletus and Spicara maena .
