The genetic polymorphism of the pike perch Sander lucioperca, sampled on the territory of the Republic of Kazakhstan (Lake Balkhash, Urals River, Syrdarya River and Shardara water reservoir, North Aral Sea) and in the Volga River, and the bersh Sandler volgensis (Lake Balkhash, Volga River) populations was examined at six microsatellite loci and the mitochondrial DNA cytochrome b gene. All examined loci were successfully amplified in both species and produced quite different allele profiles, which allows them to be used for accurate species identification of pike perch and bersh. At the same time, neither nuclear nor mitochondrial markers revealed statistically significant differentiation between the examined pike perch samples, excluding some isolation of the population from Volga River. © 2014 Pleiades Publishing, Inc.

The sturgeon fish (namely the sturgeon species Acipenser) have an important commercial value, it was originally called as red fish for its especial value. The studies targeted changes in the values of length and mass as well as production potential of various size and weight groups of Russian sturgeon 3 year olds when hatching them in the ponds of carp fish farms in a polyculture with herbivorous fish. The main results of researches, it is possible to note that the highest fish capacity when hatching in ponds is observed at 3 year of age Russian sturgeon in big size and weight group. The highest values of absolute and average daily gain during hatching in ponds are observed in 3 year of age Russian sturgeon of big size and weight group. When hatching the middle and small size and weight groups of 3 year of age the absolute and average daily gain are mainly determined by the original level of ponds' fish capacity for Russian sturgeon. © Medwell Journals, 2015.

The genetic differentiation of two populations of Balkhash perch Perca schrenki Kessler, 1874 was examined. The study included (1) the population of Lake Balkhash and the Ili River delta, where this species is protected and it is prohibited to catch them, and (2) the population of Alakol Lake system, where it is the main commercial species and forms two morphotypes, pelagic and coastal. Analysis of the mitochondrial DNA COI gene and six microsatellite loci revealed genetic differentiation at the population level, while no statistically significant differences were found at the morphotype level. The results of this study make it possible with high probability to determine the belonging of caught fish to either the commercial (Alakol Lake system) or protected (Lake Balkhash) population. © 2015, Pleiades Publishing, Inc.
