An investigation on metazoan parasite fauna of squalius recurvirostris from Düzağaç-Akdeğirmen dam lake (Sincanli, Afyonkarahisar)

In this study, the parasite presences of parasites on 66 Squalius recurvirostris from Düzağaç-Akdeğirmen Dam Lake were investigated between February 2012 and March 2013. Three parasite species were determined in the host fishes: Gyrodactylus scardiniensis (%10.6, 2.6±1.7) was found on fins of the host fish specimens; Dactylogyrus naviculoides (%89.4, 24.1±27.1) and Dactylogyrus vistulae (%63.6, 4.5±29.3) were found on gill branches of the host fish specimens; Caryophyllaeides fennica (%24.2, 2.3±1.4) was found in intestine; Paradilepis scoleciana (%43.9, 10.2±7.6) was found of mesentery of body cavity; Dilepis unilateralis (%25.8, 4.7±5.1) was found of gall bladder of the host fish specimens. Among these species, Dilepis unilateralis is a new record for parasite fauna of Turkey, and the other two species are new records for the present study area. In addition, minimum-maximum and mean intensity of parasites and infection prevalence were determined using seasonal data, size and sex distribution of the host fish. 2013, viii + 43 pages Key Words: Caryophyllaeides, Dactylogyrus, Dilepis, Gyrodactylus, Paradilepis, Squalius recurvirostris
