NEW STRAINS OF FUNGUS SAPROLEGNIA PARASITICA IN COMMON CARP (CYPRINUS CARPIO L.) FROM CYPRINID FISH BREEDING FACILITIES IN MACEDONIA

Saprolegniosis is an infectious fungal disease that is widespread in all stages of the life cycle of fish. The aim of this study was to determine the presence of mycoses in common carp (Cyprinus carpio) from eight larger and more significant cyprinid fish breeding facilities in Macedonia, by seasons and localities. For Saprolegnia isolation methodology of Njilloughbdz & Pickering (1977) was used. Identification of fungi was performed by direct microscopic method, according to the classification of Bergey (1994). We determined representatives of the genus Saprolegnia in an average 12.65 % in a total of 1134 examined fish.The identified fungus was determined as Saprolegnia parasitica, strain 111 and strain 222, which are first published findings in Macedonia.
