Harvest optimization for population, when environment conditions limiting population growth change cyclically

In this article problem of optimal harvest is solved. We assume that population dynamics is governed by Ricker's equation. Environmental conditions limiting the population growth are assumed to change cyclically with cycle length two and three. It is shown, that for these populations the optimal harvest, and optimal culling percentages are determined by the intensity оf changes of the limiting environmental conditions.

Keywords: dynamics of size population, model of Ricker, harvest optimization, limitation of size population, cyclic change of environmental conditions
