THE EXPERIENCE OF ARTIFICIAL CULTIVATION OF FRY OF THE ARAL BARBEL (LUCIOBARBUS BRACHYCEPHALUS)

This article presents the results of research to assess the growth of fingerlings of the rare and endangered Aral barbel (Luciobarbus brachycephalus) in fish farms in the Kyzylorda region. The research cover in detail the work on the cultivation of larvae in pond conditions obtained from individuals of barbel caught in the Syrdarya River in the territory of the Kyzylorda region. For research purposes, the characteristics of the pond and the water source in it are given, as well as a description of the tools for conducting control catches. The results of control catches of barbel larvae from the moment they were planted in the pond were analyzed to determine the growth rates of their main biological indicators. The deadlines and intervals of control work are also described in detail. In the conditions of the pond, the obtained results of analyses of indicators of the Fulton fatness index of barbel fry in comparison with representatives of barbel in their natural habitat are presented. During the results of growing barbel fingerlings, it was shown that the average weight of fry in the 2nd decade of September reached 15.1 g, and this indicator gives full opportunity to harvest fish planting material in the conditions of fish farms in the region.
