Abstract :Length-weight relationships insert ignore into journalissuearticles values(LWR); were described for fourteen demersal and pelagic fish species; whiting insert ignore into journalissuearticles values( Merlangius merlangus );, red mullet insert ignore into journalissuearticles values( Mullus barbatus );, picarel insert ignore into journalissuearticles values( Spicara maena );, scorpion fish insert ignore into journalissuearticles values( Scorpaena porcus );, anchovy insert ignore into journalissuearticles values( Engraulis encrasicolus );, sprat insert ignore into journalissuearticles values( Sprattus sprattus );, horse mackerel insert ignore into journalissuearticles values( Trachurus mediterraneus );, bluefish insert ignore into journalissuearticles values( Pomatomus saltatrix );, turbot insert ignore into journalissuearticles values( Scophthalmus maximus );, thornback ray insert ignore into journalissuearticles values( Raja clavata );, shore rockling insert ignore into journalissuearticles values( Gaidropsarus mediterraneus ); round goby insert ignore into journalissuearticles values( Neogobius melanostomus );, black goby insert ignore into journalissuearticles values( Gobius niger ); and stargazer insert ignore into journalissuearticles values( Uranoscopus scaber ); caught with bottom trawl insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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.
