Parasite Fauna In Common Carp (Cyprinus Carpio L., 1758) From Cage Culture System On Tikvesh Reservoir (Macedonia), Dijana Blazhekovikj Dimovska, Stojmir Stojanovski

UBT International Conference

Parasites found in freshwater fishes are primarly protozoans, myxozoans, helminth (platyhelminths, nematodes and acanthocephalans), hirudineans and crustaceans. Although both ectoparasites and endoparasites are common in fishes, internal parasites are able to cause much greater damage to their hosts than external parasites.

Over the years, cage culture has become one of the economically viable methods of large-scale production of high-value food fishes. Although, cage farming has many economic advantages, diseases are one of the major limiting factors to the successful production.

The aim of this study was to determine the presence of parasite fauna in common carp (Cyprinus carpio L. …
