This study provides the length-weight relationships of 12 fish species that belong to ten families from the Köyceğiz Lagoon, Turkey; Dicentrarchus labrax (Linnaeus, 1758); Diplodus annularis (Linnaeus, 1758); Diplodus sargus (Linnaeus, 1758); Dussumieria elopsoides Bleeker, 1849; Engraulis encrasicolus (Linnaeus, 1758); Oreochromis niloticus (Linnaeus, 1758); Gobius niger Linnaeus, 1758; Mullus barbatus barbatus Linnaeus, 1758; Sparus aurata Linnaeus, 1758; Siganus rivulatus Forsskål & Niebuhr, 1775; Solea solea (Linnaeus, 1758); Trachinotus ovatus (Linnaeus, 1758). A total of 720 fish samples were collected with fish barrier, trammel net, beach seine and cast-net. The growth type of D. annularis (b=3.148), D. elopsoides (b=3.089), G. niger (b=3.154), S. solea (b=3.124) was determined as positive allometry and E. encrasicolus (b=2.814), D. labrax (b=2.764), T. ovatus (b=2.901) was determined as negative allometry whereas D. sargus (b=2.995), M. barbatus barbatus (b=3.003), O. niloticus (b=3.088), S. aurata (b=3.009) and S. rivulatus (b=3.079) showed isometry. The results of this investigation will contribute to further fishery studies in the Köyceğiz Lagoon.
