title: [Insemination of the salmon spawn by Micromycetes at the fish-rearing farm "Pushcha-Voditsa"].
abstract: Fungi of 21 species attributed to 11 genera of three classes--oomycetes, zygomycetes, deuteromycetes--have been isolated from the surface of the Salmo gairdneri Rich. spawn and from water samples of incubation apparatuses of the fish-rearing farm "Pushcha-Voditsa" (the Kiev Region). Among the revealed micromycetes only Saprolegnia parasitica C o k e r is a fish parasite. Most of isolates are imperfect fungi; they dominate among the hyphal forms in the mycobiota of fish and water and in natural water bodies. Fusarium sporotrichiella. B i l a i, one of the isolates, is slightly toxicogenic. It affects the fish spawn viability and biochemical indices: the joint incubation of spawn and fungi induces changes in the level of water-soluble protein, amylolytic and phosphatase activity. The disturbance of the spawn envelope integrity has been observed in the experiment.
