Length-weight relationships of demersal fish species caught by bottom trawl from Eastern Black Sea (Turkey)

Abstract

Length-weight relationships were estimated for ten demersal fish species caught with bottom trawl: black goby (Gobius niger), knout goby (Mesogobius batrachocephalus), round goby (Neogobius melanostomus), whiting (Merlangius merlangus), red mullet (Mullus barbatus), turbot (Psetta maxima), scorpion fish (Scorpaena porcus), picarel (Spicara smaris), thornback ray (Raja clavata) and stargazer (Uranoscopus scaber) from the Eastern Black Sea coast. The samples sizes, minimum and maximum lengths and weights, length-weight relationships, parameters of a and b, +/- 95% CI of b, r(2), growth type (isometric or allometric), and statistical analyses of the relationship were determined.
