[The unique nature of the formation of parasitic fish fauna in the reservoirs of the Daugava River].
The formation of parasite fauna of fishes from water reservoirs of the Daugava differs from that of plain type water reservoirs of the moderate zone. Instead of expected flourishing of limnophilic elements an intense, increasing with years impoverishment of the specific composition of nearly all systematic groups of fish parasites is observed in the studied reservoirs. The impoverishment of the parasite fauna in the water reservoirs is associated first of all with their relatively small sizes, frequent and strong fluctuations of the water level and repeated dryings of large bottom areas. The investigations show that such a picture of fish parasite fauna genesis is observed in all relatively small water reservoirs with frequent and strong fluctuations of water level.
