Abstract :
Growingpopulation and the need to protein requirement forhuman societiesdevelop different systems for livestock, poultry and aquaculture provides. Caspian salmon (Salmo trutta caspius) is a species of native and migratory sea is also very important and nutritional and economic value is of particular interest. Aim this research is identifies and isolates pathogenic fungi from the skin of salmon fish farm sector of the Caspian Sea in Mazandaran (Savadkoh, Lafor - Ghazal Farm).Samples were taken from the skin of four fish weighing on the average 1300 gr in the spring 2011. Samples were transferred to Saborod Dextrose Agar, Glucose Peptone Agar and distilled water with hemp-seed in the room temperature.In this study Saprolegnia parasitica, Achlya (20.83%), Aspergillus(16.66%), Penicillium(12.5%), Acremonium (9.72%), Fusarium(8.33%), Sepedonium(8.33%), Alternaria(5.55%), Rhizopus(4.16%)Cladosporium (1.38%), Helminthosporium(4.16%), Drechslera(1.38%), were isolated from the skin of fish. Pathogenicfungus spores are everywhere and fish may be infected. So the problems in the fish treatment, lack of access to necessary medical advances of fish and high cost of drugs needed to treat, breeders must regardonbreeding and growth of fish.
