The article presents the integral diagnostics of sea water quality via biological testing on the example of the Tyulenii site. It is based on the guidelines of the Russian Register of Hydraulic Structures and the State Water Cadastre of the Ministry of Natural Resources of Russia, as well as marine toxicological biotests from the perennial experimental studies of the All-Russia Research Institute of Fisheries and Oceanography (VNIRO) on the problem of water pollution and other data that made it possible to identify the characteristics of hydrobionts’ reaction to toxic impurities. The experimental part of the research was carried out on the culture of the marine unicellular algae Phaeodactylum tricornutum Bohlin on the plankton crustaceans Artemia salina L. Comparative analysis of research in 2001–2006 shows no acute toxic effect on the test object of zooplankton and phytoplankton. Over the course of the study period, we managed to isolate the spring of 2002, when the average level of water toxicity was recorded as the lowest during the five years of research. From the results it follows that the average values of waters toxicity do not undergo significant changes and are at the same level.
