Description
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. 1758) from fish cage system on Tikvesh reservoir (Macedonia). A total of 206 specimens of common carp from this fish cage system were examined for parasitological investigations. Infestation with parasite was determined in 121 specimens (58.74 %).
In common carp from this reservoir, the presence of 5 parasite species was established: Trichodina sp., Dactylogyrus extensus, Eudiplozoon nipponicum, Bothriocephalus opsariichthydis and Ergasilus sieboldi.
In confined conditions such as cages where the stocking density is very high and the resultant stress might act as conductive factor for pathogens to cause diseases. High stocking densities coupled with fluctuations in environmental conditions and/or stress can favor parasite proliferation leading to significant mortalities in net-cage-reared fishes.
