Length-weight relationships for 47 coastal fish species from Gokceada 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.
