The authors investigated the growth of microfungi- like organisms on the eggs of pink salmon (Oncorhynchus gorbuscha) from Małki hatchery on Bystraja River, Kamchatka, Russia. Twenty two straminipilous organisms (fungus- like organisms) were found on eggs of females of pink salmon. The most commonly encountered species on the pink salmon eggs were Saprolegnia parasitica, S. salmonis, S. ferax, S. diclina, S. hypogyna, Aphanomyces frigidophilus, and Dictyuchus monosporus. However, such species as Scoliolegnia asterophora, Leptomitus lacteus, Pythium diclinum and P. monospermum are rare to salmonid fish.
