Abstract

Variations in the parameters of the life cycle in freshwater prawns of thegenus Macrobrachium Bate and some populations of the species Macrobrachiumnipponense (De Haan) were analyzed comparatively. Using factor analysis, these parameters were systematized and expressed through two factors. The first factor is related to the parameters of larval development and the dimensions of an egg, and the second, to the length of adults and their fecundity. The greatest differences in the values of intrageneric and intraspecificvariation of parameters are noted for the dimensions of larval stages. It is assumed that the formation of a species proceeds primarily through the appearance of adaptations at larval stages.
