Isolation and recognition Saprolegnia species from fungal infected eggs of the rainbow trout in Mazandaran province farms
Fungal infection in the eggs of freshwater fish is well known as a problematic disease. That isolation and recognition Saprolegnia fungi from fungal infected eggs of the rainbow trout in Mazandaran province was the aim of this research. For this purpose fungal infected eggs were examined from six fish farm in the fall and winter 2005-2006. The eggs with fungi were inoculated on SDA, CMA, GPagar and hemp seed and sesame seed cultures in sterile tap water at room temperature (18-24°C). In this study recognized three genera and six species Saprolegniaceae members, based on morphological characteristics which contain: Saprolegnia, Achlya, Brevilegnia. Four species were identified in the genus Saprolegnia; S.mixta, S.parasitica, S.moniliphera, S.lapponica and one species was identified in the genus Achlya; A.oblongata. S.parasitica was isolated from almost all the farms. In addition, another nine genera and species were identified; Penicillium, Aspergillus, Paeciliomyces, Acremonium, Fusarium oxysporum, F.solani , Alternaria, Helminthosporium, Mucor.
