Argulus foliaceus is a common parasite of freshwater fish and may occur even on amphibians as well. It often causes severe mortality of fish in fish farms and sometimes in natural waters. This long-term study aimed to determine the distribution of fish louse Argulus foliaceus in open waters and aquaculture systems in Macedonia.
Fish material from 230 specimens of Prespa roach (Rutilus prespensis), Prespa barbel (Barbus prespensis), Prespa nase (Chondrostoma prespense), Prespa bleak (Alburnus belvica), European perch (Perca fluviatilis) and common carp (Cyprinus carpio) sampled from Lake Prespa, reservoir Strezhevo and fish farm Zhabeni were examined for parasitological investigations. This study was carried out for ten years (2010 - 2020). Only fresh fish were subjected to routine identification, dissection, and observation. Cleaned parasites were separated, put in appropriate fixatives, and prepared for determination using determination techniques of staining and clearing (Vasiljkov, 1983). The parasite specimens were identified using the reference key of Bauer (1985). Classical epidemiological variables (prevalence and mean intensity) were calculated according to Bush et al. (1997).
This crustacean was found in six species of fish from three different water systems in Macedonia, namely in Rutilus prespensis, Barbus prespensis, Chondrostoma prespense, and Alburnus belvica from Lake Prespa; Perca fluviatilis from reservoir Strezhevo, and Cyprinus carpio from fish farm Zhabeni.
The records of Argulus foliaceus in Barbus prespensis and Chondrostoma prespense from Lake Prespa, as well as Perca fluviatilis from reservoir Strezhevo, are considered the first records for the fauna of parasites of fish from Macedonian waters.
In the course of our long-term investigations, one specimen of the parasite was found in each of the mentioned species of fish, so it did not cause significant problems, but the spread of the parasite must be monitored because of the consequences for the health of the fish.
