Tri-hooked monogenean parasite (Heteronchocleidus buschkieli; Ancyrocephalidae: Heteronchocleidinae) isolated from ornamental fish (colisa lalia) imported into Iran

Cüce gurami balık ile taşınan parazitler hem endemik balık populasyonlarına hem de akuakültür endüstrisine risk oluşturabilirler. Heteronchocleidus buschkieli Bychowsky, 1957 önemli bir Anabantidae balık parazitidir. Çok sayıda yurt dışından taşınan anabantid balık Güneybatı Asya ülkelerinden köken alır. Bu çalışmanın amacı İran’a Güneybatı Asya’dan ithal edilen cüce gurami balıkta monogenean parazit enfeksiyonunun mevcudiyetini araştırmaktır. Bu çalışmada, İran’a Güneybatı Asya’dan ithal edilen balıkları içeren akvaryumdan rastgele toplam 400 adet cüce gurami seçildi. Ötenaziyi takiben solungaçlar uzaklaştırıldı ve yüzgeçler ile deri monogean parazit için mikroskopta incelendi. Heteronchocleidus buschkieli (Monogenea: Ancyrocephalidae) ithal edilen balıklardan 400’ünden 120’sinde tespit edilen tek monogean parazitti. Enfekte balıklar halsiz olup hiperemik solungaçlara ve küçük deri lezyonlarına sahipti. Dört yıl için enfeksiyonun prevalans, çokluk ve ortalama yoğunluğu sırasıyla 0,3, 30 ve 30±1,96 idi. Yazarların bilgisi kapsamında bu çalışma İran’da H. buschkieli ile enfekte cüce guraminin varlığını ortaya koyan ilk rapordur. İthal edilen balıklardan bu parazitik patojenin oluşumunu engellemek amacıyla bizler ithal edilen balıkların yurt içine yayılmadan ve karantina uygulanmadan önce bu balıkların kontrol ve tedavi edilmeleri gerektiğini tavsiye ederiz.

İran’a yurt dışından getirilen süs balıklarından (colisa lalia) izole edilen üç-kancalı monogenean parazit (Heteronchocleidus buschkieli; Ancyrocephalidae: Heteronchocleidinae)

Parasites imported with dwarf gourami fish may present risks, both to native fish populations and to the aquaculture industry. Heteronchocleidus buschkieli Bychowsky, 1957 is an important Anabantidae fishes parasite. A large number of imported anabantid fish originate from Southeast Asian countries. The objective of this study was to investigate the occurrence of infection with monogenean parasite in dwarf gourami fish imported from Southeast Asia into Iran. In this study, a total of 400 dwarf gouramies were randomly selected from aquaria containing this fish imported from Southeast Asia into Iran. After euthanizing, the gills were removed and arches and skin were examined microscopically for monogenean parasites. Heteronchocleidus buschkieli (Monogenea: Ancyrocephalidae) was the only monogenean parasite identified morphologically in 120 of 400 (30%) imported fish. The infected fish were lethargic and had hyperemic gills with small skin lesions. Prevalence, abundance and mean intensity of infection for four years were 0.3, 30 and 30±1.96, respectively. To the author’s knowledge, this is the first report of dwarf gourami infection with H. buschkieli in Iran. In order to prevent the introduction of this parasitic pathogen from imported fishes, we recommend imported fishes should be examined and treated before domestic distribution and quarantine practices should be implemented.
