This study reports length-weight relationships (LWRs) of the 11 fish species in the Central Black Sea. The values of b ranged from 2.523 (+/- 0.62) for Liza aurata to 3.445 (+/- 0.56) for Sarda sarda. The median value of b was 2.933. The information about the length-weight relationships of fish species in the Black Sea is still very scarce and incomplete. The LWR for Sparus aurata was not recorded before for the Black Sea. Consequently, this paper contributes the LWR of some Black Sea fishes, especially with S. aurata and Diplodus annularis, which are given for the first time.
