Abstract

Bream (ABRAMIS BRAMA ORIENTALIS) is one of the most commercial valuable fish species of the CASPIAN SEA. Total catch of this species was 17 tons in 2000 -2001 fishing season, which constitute 0.10 % of the all commercial catch of fish species in Iranian coastal water. The mean fork length, weight and age of this species was 21.7±3.3 cm, 191±99.9 gr and 2.72±0.91 year (X±S.D) respectively. Length - Weight relationship was expressed as W = 0.2312 L 2.90 (R 2= 83.34 %, r = 0.91, N=160). Length growth parameters of bream based on Von Bertalanffys can be written as: Lt = 45 [ 1 -exp -0125(t+2.768)] The instantaneous rate of total (Z) , Natural (M) and fishing (F) mortality coefficients were 0.92 year -1, 0.28 year -1 and 0.64 year -1 respectively .The exploitation ratio (E) was calculated as 0.7 . Based on cohort analysis, the biomass of this species was calculated as 46.362 tones and according of this amount of biomass, the MSY was estimated as 14.99 tones which is less than the catch of this species.
