| چکیده [English] | ||
| This paper has been prepared by the analysis of the fish stock assessment models to present a better understanding of this science in Iran, Therefore, at the begining the basics of analysis have been taken into consideration on biologic - ecologic and mathematical bases, and then the structures of stock assessment were studied on these two bases, by use of the recent sources.The success to criticise the mathematicaf aspects of this science was pined by confirming some of the important equations of this field. Then the incertainty of this science was studied and one of the essential solutions to overcome this problem, has been recognized to b the use of more efficient mathematical basics, such as chronological series, simulation, and conditional probabilities. err this regard, the 61 year information's (1927 - 1987) about Acipenser stellatus was used and the fishing forecast was done for the years 1988 to 1992 by applying mathematical methods such as fitting, interpolation. detrend, mob... | ||
