Stock depletion level is an important concept in the assessment and management of exploited fish stocks because it is often used in conjunction with reference points to infer stock status. Both the depletion level and reference points can be highly d

A quasi-cyclicity associated with variability of environmental conditions is detected for the regression residuals of the stock-recruitment model for chum salmon Oncorhynchus keta in the Okhotsk district, described by Ricker’s equation. The main fa

The number of salmon offspring depends both on the number of parents and on the conditions of reproduction. In case of random deviations of reproduction conditions from the average long-term values, classical «stock–recruitment» models are usuall

Patchiness, defined as spatial heterogeneity in distribution of organisms, is a common phenomenon in zooplankton including ichtyoplankton. In heterogeneous landscapes, depending on the scale of prey and predatory distributions, individuals in patches

Choosing of mathematical model for describing of the pacific salmon progeny dependence on the parents abundance is discussed. Results of different approximations are interpreted. The analysis could be useful for forecasting of the pacific salmon stoc

Dependence of chum salmon Oncorhynchus keta recruitment (number of mature adults) in Okhotsky district located on the Okhotsk Sea coast on a number of spawners is analyzed for the spawning years of 1983–2014. During this period, the progeny abundan
