COMPOSITION AND STRUCTURE OF NECTONIC ASSOCIATION IN MESOPELAGIC ZONE OF SEA OF OKHOTSK

The species composition of the fishs and calamaries in the mesopelagic zone of Sea of Okhotsk has been made accurate. The characteristic signs on the quantitative composition of the mesopelagic zone necton have been studied firstly, the connection of the special features in the composition of the nectonic association with hydrology peculiarity of the Sea of Okhotsk has been shown, the special features in quantitative distribution of the basic species of the mesopelagic zone necton in the Sea of Okhotsk have been revealed, the spatial heterogeneity of its association has been considered. The average weight composition of the rations for mass species of the mesopelagic zone necton in the given region has been determined firstly, the species specifics of their feeding has been investigated. The values on the annual consumption of the zooplankton and necton by the mesopelagic zone necton in different years have been evaluated, the trophic connections of the necton in the mesopelagic zone of the Sea of Okhotsk have been determinedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
