Abstract :This study was performed in order to assessment of the turbot insert ignore into journalissuearticles values(Scophthalmus maximus); Stock from Southeastern Black Sea during April-September 1990 and September-October 1991. From the length-age data for both sexes, the following population parameters were estimated: Length-Weight relationship, W=0.0085*L3.18; v. Bertalanffy growth constants, L?insert ignore into journalissuearticles values(mm); = 825.7, Kinsert ignore into journalissuearticles values(year-1);=0.17, to insert ignore into journalissuearticles values(year);=-0.93, W?insert ignore into journalissuearticles values(g); = 10590.43; total mortality and its components, Z=0.48, M=0.30 and F=0.18. Standing biomass of the turbot between 0 and 100 m depth range in September-October 1991 was found to be 407.6 tonnes and also there was an under exploitation rate on this stock as a rate of E=0.37.
