Fisheries statistics as indicator of stock assessment of marine invertebrates
2017
Buyanovsky, A.I. | Alekseev, D.O.
This paper discusses applicability of fisheries statistics for marine invertebrates stock assessment. Advantages, disadvantages, limitations and possible sources of uncertainties of fisheries statistics are analyzed. The different methods of CPUE standardization are proposed for different stocks of marine invertebrates. The minimum significant number of CPUE queries from the Data Base should be not less than 10. Together with traditional methods of spatial and temporal divisions of annual data, the new method for definition of seasons based on pairwise comparison of catches in neighbor months is proposed. Effect of “vessel factor” on integral estimation of CPUE and involving this factor in analysis of catches dynamics by GLM (general linear models) method is discussed
