Mathematical modelling of population dynamics of Baikal omul under commercial catch

Abstract

Despite the imposed restrictions to conserve the abundance of Baikal omul, the problem of reducing biomass is still urgent. Over the past ten years, the total biomass of Baikal omul has shown a three-fold decrease. The decline of omul stock required to impose another restriction of fishing activity in the water area of Lake Baikal. The order of Ministry of Agriculture of the Russian Federation of 29 August 2017 No. 450 amended the fishing rules for the Baikal fisheries basin, banning the commercial catch of Baikal omul and restricting amateur and sports fishing as well as traditional fishing for indigenous small-numbered peoples, starting from 1st October 2017.
