Abstract

Length-weight relationships (LWR) were described for fourteen demersal and pelagic fish species; whiting ( Merlangius merlangus ), red mullet ( Mullus barbatus ), picarel ( Spicara maena ), scorpion fish ( Scorpaena porcus ), anchovy ( Engraulis encrasicolus ), sprat ( Sprattus sprattus ), horse mackerel ( Trachurus mediterraneus ), bluefish ( Pomatomus saltatrix ), turbot ( Scophthalmus maximus ), thornback ray ( Raja clavata ), shore rockling ( Gaidropsarus mediterraneus ) round goby ( Neogobius melanostomus ), black goby ( Gobius niger ) and stargazer ( Uranoscopus scaber ) caught with bottom trawl (12 mm mesh size) from the Eastern Black Sea. Samples were caught in depths from 10 m up to 60 m between April 2017 and March 2018 at monthly intervals. The 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) of samples, and statistical analyses of the relationship were determined. Estimates for parameter b of the length–weight relationship ranged between 2.44 and 3.54.
