P. 510-518The aquatic fungi cultured from eggs, alevins and broodfish of brown trout Salmo trutta
belonged to the genus Saprolegnia and were identified as S. diclina, S. australis, S. ferax,
S. furcata, S. hypogyna, S. unispora and S. parasitica. The species obtained from infected eggs and
alevins were different to those from infected fish. Several Saprolegnia species were isolated from
eggs and alevins, whereas all the isolates obtained from broodfish were the pathogenic
S. parasitica.S
