In order to prevent outbreaks of fungal infections in reservoirs with crayfish we recommend to (1) performa bioassay on the disease of crayfish with aphanomycosis (crayfish plague); (2) determine the incidence of crayfish with signs of mycosis called burn-spot disease (BSD); (3) check for contamination of coarse grains with agents of mucoriosis; (4) oppose the ingress into the reservoir of waste water from cultivated fields carrying agents of fusariosis; (5) prevent over consolidation of crayfish population. These measures are taking into account the ability of pathogenic oomycetes to quickly infect crayfish with mobile zoospores, long-term viability of chlamydospores (gemmae) of Saprolegniaparasitica and oogoniaof Aphanomyces astaci. These factors support the infection in the reservoir and prevent the recovery of crayfish populations after outbreaks of mycoses.
