This study was performed in order to assess turbot (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(?)(mm) = 825.7, K(year-1)=0.17, t(o) (year)=-0.93, W(?)(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.
