Abstract
In this study 288 length-weight relationships of some fish species from the Turkish coasts of Black Sea were gathered from 138 studies, which were conducted by several researchers between 1989 and 2021. For all species, the “b” values ranged from 2.49 for Trachurus trachurus to 3.75 for Alosa caspia. The expected range of 2.5<b<3.5 is confirmed for fish. It is thought that the high b value (3.75) given for A. caspia may be due to the size composition of the samples. Within species, a plot of log (a) vs b was used to detect outliers in weight–length relationships. In study, two outliers were determined for Mullus barbatus while, one outlier was determined for Belone belone, Alosa immaculata, Merlangius merlangus and Neogobius melanostomus.
