Abstract
In this study, some of biological indices of crooker fish (Otholithesruber) were investigated in Khozestan coasts. Sampling was done each month, from March- 2014 to February- 2015 by near bottom trawl net with 24milimeter mesh size in commercial fishing. After fishing the samples transported to the lab and were biometry. The result of study 307 number of crooker fish showed that the total weight mean was 220.56±9.1 geram and total standard length was 23.59±0.24 centimeter. Length and weight parameter relationship was measured, too. Length and weight equation was calculated as a regression equation, y=0.0172X2.826 and R2=0.8247. In this equation, a and b Parameters were calculated as 0.0172 and 2.826, respectively. The variation of some biological indices such as intensity of feeding index, hepatosomatic index and gonadosomatic index were studied too. The results of biological indices showed that hepatosomatic index was related positively to intensity of feeding and gonadosomatic indices.
