The reason for undertaking this work was the low production rate of fish in many lakes and reservoirs, limited by the poor food supply, chiefly low biomass and production of benthos. Introduction of invertebrates was carried out from 1947 to 1968 in 57 reservoirs and over 100 fresh- and brackish water lakes situated over an enormous area from the Baltic Sea on the north-east to the Caucasus Mountains in the south and the Obi basin in the east. In 70% of the cases introduction proved completely successful. The organisms transferred acclimatized themselves to new conditions, increasing biomass and production of biological communities forming the food of the fish. There has been a consequent increase in fish production in many lakes and reservoirs, the economic effects of which have greatly exceeded the cost of introducing invertebrates into these waters.About 50 species of invertebrates were used in such introductions, primarily Crustacea — Amphipoda, Mysidacea and Cumacea and in addition Mollusca and Polychaeta. Nearly 75% of the species introduced came from the Ponto-Caspian estuarine faunistic complex, while the remaining 25% consisted of postglacial relicts, Baikal relicts and representatives of Far East fauna (Table V). The successful results of acclimatization of many species of invertebrates in the waters of the Soviet Union form an inductement to consider the possibility and need of introducing water invertebrates into waters in Poland. The purpose of such operations would be not only to improve fishery management, but also to reconstruct the fauna of waters subject to strong anthropogenic influence, e.g. heated water discharges from electric and atomic power-stations, salination by discharge of mine water etc. Since however the introduction of alien faunistic elements may also induce a many-sided and possibly also unfavourable effect on existing biocenoses, it is essential to undertake detailed studies on these problems.}, title={Introdukcje bezkręgowców do wód śródlądowych i ich perspektywy w Polsce}, type={Text}, URL={http://www.rcin.org.pl/Content/153773/PDF/WA058_107840_P3259-22_Eko-Pol-B.pdf}, volume={22}, number={1}, journal={Wiadomości Ekologiczne}, publisher={Państwowe Wydawnictwo Naukowe}, keywords={introduced freshwater organisms, biological productivity, productivity, biological, aquatic ecology, aquatic habitats, freshwater biology, invertebrates, Invertebrata}, }
