A method to estimate the mortality rate of fish in Lake Khanka

Abstract
A new methodic approach is proposed that allows to formalize and refine the expert assessments of the basic parameters of fish population dynamics obtained by indirect methods, such as reproduction and mortality rates, and to compensate partially gaps in fishery statistics. It is based on well-known results of Tyurin [1972], Richter and Yefanov [1977], and Zykov and Slepokurov [1982] concerning the total mortality rate dependence on fishing pressure in exploited fish populations. The mortality rate can be used as a criterion for effectiveness of fishery regulation measures.
