Karamık Gölü (Afyonkarahisar)'deki Cyprinus carpio Linnaeus, 1758 (Sazan)'nun metazoon parazitleri üzerinde anatomik, morfolojik ve ekolojik bir araştırma

13 Mart 2004 ile 28 Mayıs 2005 tarihleri arasında yapılan bu araştırmada, Karamık Gölü (Afyonkarahisar)’nden yakalanan 71 Cyprinus carpio Linnaeus, 1758 (sazan)’nun metazoon parazitleri üzerinde incelemeler yapılmıştır. Konak balıkta üç parazit türü tanımlanmıştır: Gyrodactylus elegans, Nordmann, 1832; Dactylogyrus extensus Mueller ve Van Cleave, 1932 (Monogenoidea, Plathelmintes); Bothriocephalus acheilognathi, Yamaguti, 1934 (Cestoidea, Plathelmintes). Bu türlerden G. elegans 16 balığın yüzgeçlerinde (% 22,5; 7,6 parazit/balık) ve 2 balığın solungaçlarında (% 2,8; 5,0 parazit/balık), D. extensus 65 balığın solungaçlarında (% 91,5; 22,1 parazit/balık), B. acheilognathi ise 10 balığın bağırsaklarında (% 14,0; 10,8 parazit/balık) görülmüştür. Konak balıktaki dominant parazit türü D. extensus’tur. İlgili parazite ait en yüksek enfeksiyon oranına ve parazit sayısına kış aylarında, en düşük değerlere ise ilkbahar ve yaz aylarında rastlanılmıştır. D. extensus ile enfekte olma oranı küçük boylu sazanlarda büyüklere göre daha fazladır. G. elegans, orta boylu sazanların yüzgeçlerinde ilkbaharda, solungaçlarında ise kış aylarında kaydedilmiştir. Küçük ve orta boylu sazanlarda görülen B. acheilognathi enfeksiyonu kış aylarında yüksek, ilkbahar ve yaz aylarında ise düşük bulunmuştur.

An investigation on anatomy, morphology and ecology of metazoan parasites Cyprinus carpio Linnaeus, 1758 (common carp) from Lake Karamık (Afyonkarahisar)

An investigation on anatomy, morphology and ecology of metazoan parasites of Cyprinus carpio Linnaeus, 1758 (common carp) from Lake Karamık (Afyonkarahisar). In this study, the presence of metazoan parasites on 71 Cyprinus carpio Linnaeus, 1758 (common carp) was investigated in Lake Karamık, Afyonkarahisar, Turkey between 13th March 2004 and 28th May 2005. Three parasite species were identified in the host fish species: Gyrodactylus elegans, Nordmann, 1832; Dactylogyrus extensus Mueller ve Van Cleave, 1932 (Monogenoidea, Plathelminthes); Bothriocephalus acheilognathi, Yamaguti, 1934 (Cestoidea, Plathelminthes). From these species, G. elegans was found on the gills of 2 fish (% 2.8, 5.0 parasite/fish) and on the fins of 16 fish (% 22.5, 7.6 parasite/fish). D. extensus was found on the gills of 65 fish (% 91.5, 22.1 parasite/fish). B. acheilognathi was found in the intestine of 10 host fish (% 14.0, 10.8 parasite/fish). D. extensus was the dominant species found on the host fish. The highest infection rate and mean parasite was in winter and minimum value was in summer and spring. The smaller common carp have more infection rate than larger common carp specimens by D. extensus. G. elegans was found on middle size fish’s fins in spring, on the gills in winter. The infection rate occurred by B. acheilognathi was more common in small and middle size host fish species in winter than in spring and summer.
