Abstract

This study was conducted to determine growth parameters and Mortality of sharp nose mullet (Cheloc saliens). A total of 442 specimens collected using small beach siene in Gorgan bay from June to October two successive years of 2016 and 2017. The samples included 210 males and 232 females. Growth parameters calculated using Gulland and Holt method, and the length frequency analysis done using ELEFAN and Shepherd methods in FISAT software. Observed length-weight relationship was W=0. 0084L 3. 018 for males and W=0. 010L 2. 954 for females. After fitting the regression using least squares method, the non-linear relationships were W=0. 009L 2. 977 and W=0. 013L 2. 855 for males and females, respectively. The results showed that there are two cohorts (with mean values of TL 7. 34 and 17. 06 cm) in males and three cohorts (with mean value of TL 6. 84, 15. 28, 20. 76 cm) for females. Fitted K and L∞ of VBGF were 0. 270 year-1 and 32 cm for males, and 0. 235 year-1 and 34 cm for females. Total Mortality rate which calculated using linear catch equation, was 1. 39 and 1. 07 year-1 for males and females respectively. In general, this species inhabiting the Gorgan bay has population dynamics characteristics similar to those of the r-selection strategy.
