The paper summarizes knowledge on changes of ecological situation in Nevskaya Bay (the eastern part of the Gulf of Finland) during the last several decades which had caused considerable decrease of local smelt population. Among the negative factors, which affected the collapse of the smelt, several reasons should be mentioned especially: reduction of the fish supply in the sea, the influence of the dam (of the protective constructions complex against the flood of the city), intensification of the hydro-technical works in the Nevskaya Bay, illegal fishery, not-correct estimation of the TAC. The range of the concrete measurements is suggested to improve the modern situation with Nevskaya smelt population
