ABSTRACT

Periods of rise and decrease of activity of hydrolases and content of protein and lysozyme are observed from the moment of fertilization of spawn of Donaldson's trout until the appearance of larvae. The dynamics of proteolytic and lipase activities in healthy embryos and those infected by saprolegnia fungi (Saprolegniomycota) reveal reverse correlation. As for amylolytic and phosphatase activities, correlation coefficients are not significant, and a positive correlation was found for the content of lysozyme. The data obtained testify to negative influence of saprolegnia fungi on the development of trout during embryogenesis.
