CONTROL OF FISH FUNGAL PATHOGEN SAPROLEGNIA PARASITICA USING ROTIFER BRACHIONUS PLICATILIS AND SODIUM CHLORIDE

El-Kassas H. Yassin Abdel Aziz N. El-Said.

Abstract
This investigation was designed to compare between the inhibiting effect of sodium chloride and the rotifer Brachionus plicatilis on the growth of a fish pathogen, Saprolegnia parasitica as safe remediation techniques in aquacultures. The results showed that the addition of 100 cells of B. plicatilis, caused decrease in spores count of S. parasitica, by 34% after 2 hours, and 79% after 6 hours, respectively. Increasing the number of B. plicatilis to 150 cells decreased the spores count of S. parasitica by 80.00%. The two way analysis of variance showed that the tested rotifer species exhibited a great efficiency in grazing fungal zoospores (P<0.001). On the other hand, NaCl so¬lution reported stronger effect on the growth of the tested fish pathogen as compared to that occurred by the rotifer species. After 14 days of incubation, S. parasitica was markedly suppressed (P<0.001) at different concentrations of NaCl so¬lution.

Key words: Saprolegnia parasitica, Sodium chloride, Brachionus plicatilis, Pathogenic inhibitors, Lake Edku
