Abstract:   (156 Views)

In this study population dynamic of Acipenser persicus with age structure model by Monte Carlo and Bootstrap approach was studied. Length frequency data a total of 4376 specimens collected from beach seine, fixed gill net and conservation force in coastal Guilan province during 2002 to 2012. Data imported to FiSAT II for length frequency analyze by ELEFAN 1. K, L and t0 estimated 203, 0.08 and -0.94 respectively. Total and natural mortality estimated 0.26 and 0.14 year-1 respectively. The exploitation rate (E) was computed 0.61. Confidence limit of Z was obtained 0.195-0.327 year-1 by Bootstrap method. At Monte Carlo simulation method, confidence limit of Z was calculated 0.169-0.289 year-1 with considering sampling error. Result of the present paper demonstrating that considering the uncertainty of population parameters of selected species could be useful for increasing the accuracy at stock assessment models.
