Abstract

Glaucostegus cemiculus individuals were collected from two different areas, the estuary of the Gediz River, Izmir Bay (Aegean Sea) on the west and Karataş, Iskenderun Bay on the northeastern coasts of the eastern Mediterranean. Total of 383 individuals (190 male, 193 female) were examined. Individuals ranged between 30-148 cm TL and 81-12010 g. The length-weight relationships were estimated for each area, each sex and combined data, and for Izmir Bay, Iskenderun Bay and combine data were all positive allometry and was as W=0.0021L3.13, W=0.0015L3.15, and W=0.0018L3.12, respectively.

Keywords: Glaucostegus cemiculus, length-weight relationships, eastern Mediterranean, Izmir Bay, Iskenderun Bay
