Abstract

The study investigated the growth of hydromycoflora on the eggs of common carp (Cyprinus carpio L.) in five water bodies of different eutrophication levels. Thirty-three (33) species of mycotal organisms, including 28 species belonging to Peronosporomycota, 2 to anamorphic fungi and 1 each to Ascomycota, Blastocladiomycota and Zygomycota were identified on the eggs. The water from River Biala and Pond Fosa, which are more biogenic, had the largest number of mycotal species (20 and 19, respectively) on the eggs of common carp. The smallest number of those species was found on the eggs of common carp in water from Spring Cypisek, Pond Komosa and River Suprasl, which are low in biogenes (12, 11 and 11, respectively). Achlya diffusa, Aphanomyces laevis, Saprolegnia ferax, Saprolegnia parasitica and Pythium ultimum belong to the species that were most frequently found on C. carpio eggs. The following rare mycotal species were also found: Allomyces arbuscula, Aphanomyces frigidophilus, Candida albicans, Fusarium aquaeductum, F. culmorum and Zoopage phanera. Amino acid, carbohydrate and urease tests were used. Of the C. carpio eggs that were investigated, 12.7% were found to be infected with mycotal species.
