[Effect of warm waters of the Konakovskaia hydro-electric power plant on the infectibility of the young of the roach with Myxosporidia].
Data are given on the effect of warm waters of the Kanakovskaya hydro-electric power station on the infection level of the roach young with myxosporidians. 1641 one-year old specimens of roach were examined. 11 species of myxosporidians are reported from the zone of warm waters influence while in the control gulf beyond the warming zone--only 7 species. Within the larval period only two species, Chloromyxum legeri and Zschokkella costata, were recorded. Their developmental cycle was retraced. Under the influence of warm waters the developmental period from plasmodium to spore in Ch. legeri is accelerated: from 20 days to "cold" waters to 15 days in "warm" ones. In winter period in warm water zone a sporeformation of many species of myxosporidians takes place. At the same time the infection with plasmodial stages keeps on a high level that indicates to a continuous active feeding of the young even in winter.
