THE MACROZOOBENTHOS OF THE ARALSKY SEA NORTH PART COASTAL WATERS UNDER THE UP TO-DATE POLYGALINN CONDITIONS

By Andrey Alexandrovich Filippov

Abstract

The object of investigation: the macrozoobenthos, bottom organisms. The purpose of the work: the determination of species composition, number and biomass of the bottom invertebrates in the coastal zone of the Aralsky sea, and evaluation of effect on the structural characteristics of the macrozoobenthos of the sea salting and its level fall. For the first time, a detailed picture of the spatial distribution of the bottom invertebrates of the Aralsky sea has been presented, and revealed have been the factors of the medium, determining the character of its vertical distribution. The upper boundaries of the potential salt-bearing tolerant ranges of the bottom invertebrates have been determined. The received data by the character of distribution of the bottom invertebrates and by the limits of its salt-bearing tolerance, allow to evaluate the possible consequences of further sea salting and the fall of its level. The results of the work can be used for prognosing the changes of the food base of the fishery. The field of application: the hydrobiology, protection of nature, the common ecologyAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
