Abstract

The authors investigated the growth of straminipiles fungi on the alevins of Nile tilapia (Oreochromis niloticus niloticus L.) in water from eight limnologically and trophically different water bodies. Twenty-seven species were recorded. The largest number of species occurred on alevins in water from the Biala River and Fosa Pond (more biogenic), and the fewest in water from Dojlidy Pond and Lake Blizno (poor in biogenesis). The most commonly encountered species on Nile tilapia alevins were Saprolegnia parasitica, Saprolegnia ferax, Achlya polyandra, Achlya  oligocantha, Achlya prolifera, Leptomitus lacteus, and Pythium diclinum. Amino acid, carbohydrate, and urease tests were used.

 

Key words: Oreochromis niloticus, alevins, straminipiles infections, hydrochemistry.
