BACTERIOLOGICAL AND PARASITOLOGICAL STUDY OF CULTURED COMMON CARP (CYPRINUS CARPIO, L. 1758) FROM CYPRINID FISH FARM IN PELAGONIA REGION (BITOLA, MACEDONIA)
The common carp (Cyprinus carpio, L. 1758) is apparently the most widely geographically distributed fish species in the world. Regarding its adaptation to a wide range of climatic and geographical conditions, a substantial number of almost all major taxa of parasites have been found in wild and domestic carp. Freshly harvested aquaculture products, particularly those from aquaculture, may contain pathogenic bacteria which are part of natural micro-flora of fish farms. Parasitic infestation and bacterial contamination of cultured fish represents a serious problem for aquaculture due to severe economic losses either as directly or indirectly. Specimens of common carp from cyprinid fish farm in Pelagonia region (Bitola, Macedonia) were examined for bacteriological and parasitological investigations. In common carp from this fish farm, the presence of 1 parasite species, Dactylogyrus extensus was established, as well as, following bacteria on fish skin have been recorded: Escherichia coli, Enterococcus sp., Serratia sp., Staphylococcus aureus and Staphylococcus saprophyticus. Moreover, it is necessary for the fish farms to improve fish farming management, as well as, environmental sanitation and monitoring for quality fish yield
