Invesrigating growth and mortality parameters of Mudskipper Boleophthalmus dussumieri Valenciennes, 1837 in mongrove forests in Khamir port in Hormozgan province

The growth parameters of B. dussumieri, Valenciennes, 1837 were studied using length frequency data related to 281 specimens of this species that were collected by hand and dip net from mangrove forest in Khamir port in Hormozgan province during september 2015 to June 2016. Using FiSAT II program, growth parameers were calculated. Also growth was was estimated by the Von Bertalanfy growth model. The results showed that growth parameters for B. dussumieri were: Lt=22.1{1-exp [-0.51(t-0.347)]} for male and Lt=21{1-exp[-0.51(t- 0.35)]} for female. The meane lenght of B. dussumieri specimens caught in the study area 14.54±3.42 cm for males and 14.88±3.35 for females. The means of weight for males and females were 21.52±11.72 gr and 24.28±13.37, respectively. The numerical amount for b was found to be 2.56 and 2.63 for male and female respectively. The natural mortality coefficient were 1.23 and 1.21 in female and male. Accordinf to the diagrams and equations, females grew to a greater asymptotic length (L∞). The length-weight relationship for males and female were W=0.020 L2.56 (r2=0.968) and W=0.017L2.634 (r2=0.958), respectively.
