The potential of mariculture and artificial reproduction of the red king crab Paralithodes camtschaticus for the stabilization of biological resources

Abstract

Based on the assessment of the natural population of the red king crab, the work on the biotechnology of artificial reproduction of this valuable commercial species is especially important. The paper presents the results of a study of the effect of stocking density and water temperature on the survival of red king crab fry at early stages of development (less than one year). Studies were conducted to assess the survival of yearlings and the rate of weight growth depending on the temperature conditions of maintenance. Three temperature ranges were tested: 1 - between sublethal 15 ° C and lethal 24 ° C; 2 - between sublethal 15 ° C and optimal 8-10 ° C; 3 - optimal from 8 to 10 ° C.
