Title

IDENTIFICATION AND INCIDENCE COMPARISON OF ISOLATED FUNGI FROM CASPIAN KUTUM (RUTILUS FRISII KUTUM) EGGS IN MAZANDARAN PROVINCE

Pages

  79-90

Abstract

 Fungal infections in the fish hatchery are well known as problematic diseases. The aim of the present study was to isolate and identify FUNGI which caused Caspian kutum EGGS mortality and evaluation the effects of water physical and chemical factors on their prevalence. Kutum EGGS with fungal hyphea and water samples were collected from hatcheries three times in propagation seasons from 2004 to 2007. Finally 1350 EGGS and 45 water samples were examined (totally 4050 infected EGGS and 135 water samples). The soluble oxygen, temperature, pH, NO2-1, NO3-1 and NH4-1 were measured as water physical and chemical factors. The EGGS were inoculated in culture media (YGC agar and SD agar) and incubated at same hatchery temperature. The results showed Saprolegina species were only aquatic FUNGI isolated from kutum EGGS in examination time, whereas the most important saprophytic FUNGI species based on incidence were Fusarium sp., Penicillum sp., Aspergillus sp., Moucor sp., Pscilomyces sp. and Alternaria sp. respectively. The most and the least incidence percent of Saprolegnia sp. were observed in 2005 and 2007 respectively. However, incidence percent of saprophytic FUNGI completely showed the opposite results. The results of water physical and chemical factors were shown that temperature, soluble oxygen, pH, NO2-1, NO3-1 and NH4-1 had a significant difference between 2005 and another two years. It is clear from the present study there may be straight relations are between water physical and chemical factors and incidence of aquatic and saprophytic FUNGI.
