The aim of the research activity was to make the inventory of the biodiversity of the marine fish fauna of the State Nature Reserve “Utrish”. The object of the investigation was the fish fauna of the State Nature Reserve “Utrish” within the various type of the genesis and salinity – marine area and the brackish lakes near the coastline. According to the field observations and ichthyoplankton researchthefish species list of the currently dwelling fish species of the reserved water areawas made. In the warm season in the marine area of the reserve the 64 fish species from the 46 genera, from 36 families and 14 orders were reliable confirmed. Near the 60 % of the biodiversity was composed by representatives from the 10 families.Generally, the fish fauna is strongly marked as “marine”; the marine fish are prevailing and amount more than 87 % of the biodiversity. Non- and little migratoryfish amount more than 65 % fish species. The ecological structure of fish fauna according to the type of feeding is represented by the eight ecological groups, predominantly by the benthos feeders. The fish communities’ structure according to the using of the spawning substratum is represented by six ecological groups, predominantly by the pelagophilic fish. Among the fishspecies, registered as a result of our research, one species is listed to The Red Book of the Russian Federation, rour species have protected status in The Red Book of the Krasnodar region; according to the IUCN Red List two species are critically endangered, two species are vulnerable and four species are near threatened.

We consider the results of monitoring of the reproductive populations of 80 species of birds and their mulmtiparametrnaya assessment Guba-Altiaghac areas for 2013-2016. Of these Lip portion 63 has, on a portion 75 Altiaghac species. The reasons lischeniya of repro-induction 19 species of birds in these areas over the past 50 years. The status of all reproductive (S + N) of birds estimated multiparametrnym method. The elimination of the birds over the last 3 years was the focus of the authors.
