As a result of long term studying of the physiological and biochemical status of roach populations in modern environmental conditions of Volga-Caspian region it was revealed that breeders has a significant shortage of lipids and protein during pre-wintering and spawning periods, determined the level of sexual products development, the success of spawning migration and, respectively, the commercial catches. The minimal level of fat, limiting its spawn migration, was determined as a result of studying of physiological status of breeders. The way of new data integration to the method of evaluation of total legal catch with aim of its further improvement by the specialists of catch’s statistics was offered
