The research has shown the domination of fluctuative trends in the biomass dynamics for a majority of the caught fish species and decrease in the stocks of littoral phytophil fish. The main reason of the fishery breakdown of the pike perch in Łebsko and perch in Sarbsko was exploitation at a too big scale. The resources of the mentioned fish populations were drastically violated in the first decade of the 47 years of exploitation, that is in the years: 1952-1999. However, the highest fishing level of most of the fish species in annual cycles was achieved notoriously at spawning periods during the whole 47 years. It just goes to show a complete ignorance of valid periods and the protective dimensions in the fishery practice. In the consecutive decades and for all the 47 years, the position and the degree of mass dominance for separate species of fish in fishing have been established. Pairs of superdominants and eudominants with the greatest quantitative participation in fishing have been distinguished for each of the lake. For the regeneration of the pike’s, the tench’ and the crucian carp’ population fishing of those species should be banned for the time of their generation. Reduction to small Cyprynidae species should be conducted by intensive stock in Łebsko with the pike and in Sarbsko with the pike-perch.

Key words: catchment area, mass dominance, estuary lakes
