Length-weight relationships of marine species caught by five gears from the Black Sea

Abstract

The length-weight (L-W) relationships of 19 fish species, 4 molluscs and 2 crustacean species, caught during January 2009 and November 2011, are presented. The mean value of 'parameter b' was 2.881±0.399, ranging from 1.758 to 3.616. The L-W relationships for all studied species were significant (P<0.01), whereas they were isometric only for three species (i.e. Scorpaena porcus, Pomatomus saltatrix and Neogobius melanostomus).
