Abstract
Ecological and genetic consequences of optimal equilibrium harvest with constant quota in uniform and two-aged populations have been considered in this work. It has been shown analytically that maximum of equilibrium harvest income is unreachable when both age groups are harvested simultaneously. The optimal strategy of harvest is the catch of fixed portion from single age group. In addition, optimal harvest may result not only in a change in the dynamic mode of the system, but also in a considerable change in the genetic composition of the population.
Dynamics of Genetic Structure of Population with Age Structure during Optimal Harvest with Constant Quota
Ecological and genetic consequences of optimal equilibrium harvest with constant quota in uniform and two-aged populations have been considered in this work. It has been shown analytically that maximum of equilibrium harvest income is unreachable when both age groups are harvested simultaneously. The optimal strategy of harvest is the catch of fixed portion from single age group. In addition, optimal harvest may result not only in a change in the dynamic mode of the system, but also in a considerable change in the genetic composition of the population.
