Biology and fishery of horsehair crab Erimacrus isenbeckii in the eastern Okhotsk Sea
Abstract
The horsehair crab Erimacrus isenbeckii fishery develops actively in the eastern Okhotsk Sea since 2017. The main commercial aggregations of this species are located around the 40 m isobath in the Kamchatka-Kuril fishing subzone. Significant fluctuations in its abundance and distribution density are noted. The maximum density of the crab aggregations up to 4,300 ind./km² was observed in 2024, when the stock was assessed in 3.8 . 106 ind. The fishery is regulated taking into account seasonal dynamics of molting and distribution of functional groups. The results of the study allow to optimize the resource management strategy and to provide sustainable exploitation of the horsehair crab population at southeastern Kamchatka.
