MORPHOBIOLOGICAL CHARACTERISTICS OF THE BALKHASH MARINKA SCHIZOTHORAX ARGENTATUS FROM THE TOKYRAUYN RIVER (BALKHASH BASIN)

Abstract

Marinka (Schizothorax Heckel, 1838) together with the Ottomans and the Ottomans-nagortsy form a subfamily of white-bellied cyprinids (Schizothoracini), relative to Nikolsky G. V. (1980) to the Nagorno-Asian freshwater faunal complex. Balkhash Marinka Schizothorax argentatus in the reservoirs of Kazakhstan has always been relatively small. Within Kazakhstan inhabits the basins of the Balkhash-Alakol basin. Before the acclimatization of the common carp in the Balkhash basin, the Marinka was a background view of the lake and the rivers flowing into it. It was used fresh, mostly smoked. Currently, the population of the Balkhash marinka Schizothorax argentatus has critically decreased. Lost its commercial significance. In this regard, the Balkhash marinka listed in the Red List of Threatened Species of the International Union for Conservation of Nature (IUCN) as vulnerable (VU) is an endemic species. This paper examines the current state and morphological and biological characteristics of the endemic marinka species from the Tokyrauyn River (Balkhash basin). The results of the analysis of morphobiological indicators are presented. A description of the appearance of the marinka is given.
