Abstract
The purpose of this project was to investigate the distribution and possible pathogenic role of ecto-and endoparasites of freshwater fishes in some areas of Central Anatolia. Totally 999 fishes from different areas of Central Anatolia were collected and examined between the years of 1981-1984. The fish samples were talken mainly from Gölbaşı-.Eymir lakes and Çifteler Sakaryabaşı Fish Breeding and Research Station. With a few exceptions fish samples were taken monthly from these two places mentioned above, during the first two years of project. In. addition to these places, fishes were also obtained from three dam lakes (Kurtboğazı-Hirfanlı-Sarıyer), two streams • (Kızılcahamam-Nallıhan) and one pond (Çankırı, Günerdiğin). Fishes were caught by nets and transferred to the laboratory in the plastic bags filled with equal volumes of water and oxygen. As a result most of the fishes were alive before examination. Both farmed and feral fishes (Cyprinus carpio, Tinca tinca. Salma gairdneri, Alburnus sp. , Silurus glanis, Esox lucius, Barbus. sp .. Varicorhinus sp., Chondrostoma sp., Blicca bjoerkna, Aspius aspius) were caught. Immediately after killing, fishes were controlled for• ecto- and endoparasites. This control comprised ıbody surface, gill, body cavity, blood and heart. swimming bladder, liver, kidney, digestive tract and muscles. Species and number of examined fishes from each places. local and general distribution and percentage of their parasites were recorded. The following parasites were found. I) Ectoparasites a) Protozoa : Trichodina sp. (T.domerguei, T.nigra), . Trichodinella sp., Ichtyophthirius multifilüs, ;Apiosoma sp., ,Chilodonella cyprini, Costia necatrix, Cryptobia branchialis. b) Crustacea : Argulus foliaceus (Carp louse), Ergasilus sp . Lernaea cyprinacea (Anothor worm). c) Monogenea : Dactylogyrus sp., Gyrodactylus sp. d) Metacercariae : Clinostomum complanatum (from Alburnus) and other. e) Nematode larvae Unidentifled f) Mucophilus cysts II) Endoparaısites a) Protozoa : Trypanosoma sp., Trypanoplasma sp., Coccidia (Eimeria sp.), Myxozoa (Myxosoma, Myxdbolus, Myxidium. Spherıospora), Hexamita sp. b) Digenea : Sanguinicola sp. {eggs), Asymphylodora tincae and unidentified m:etacercariae. c) Cestodes : Ligula intestinalis plerocercoids, Proteocephalus osculatus, Caryophylleus laticeps. l'arval Cylophyllidean cestodes. d) Nematoda : Philometra intestinalis e) Acanthocephala : Pomphorhynchus laevis, Neoechinor hynchus rutili The rate of infection with one or more parasites varied with different species of both fish and parazites, sampling origin and season of the year. Of the 999 fishes examined 597(59.7%) were found to harbour parasites.
Özet
1981-1984 yılları arasında İç Anadolu bölgesinde değişik yörelerinden 999 tatlısu balığının paraziter yönden kontrolü yapılmıştır. Balık örnekleri Çifteler Sakaryabaşı Balık Üretim ve Araştırma istasyonu ile Gölbaşı-Eymir göllerinden projenin ilk iki senesi her ay alınmış, ayrıca değişik zamanlarda 3 baraj gölünden (Kurtboğazı, Hirfanlı, Sarıyer), 2 dereden (Kızılcahamam- Nallıhan) ve 1 göletten (Çankırı, Günerdiğin) yakalanan balıklarda kontrol edilmiştir. Hem kültür hem de yaban balıklarının (cyprinus carpio (Sazan), Tinca tinca (Kadife), Salmo gairdneri( Alabalık), Alburnus sp. (Gümüş-İnci), Silurus glanis (Yayın), Esox lucius (Turna), Barbus sp. Varicorhinus sp. Chondrostoma sp. , Blicca bjoerkna ,Aspius aspius)kontrolleri yapılmıştır. Ağla yakalanan balıklar, yarıyarıya su ve oksijen içeren naylon torbalar içinde canlı olarak laboratuvara getirilmiş ve muayene öncesi öldürülerek ekto- ve endoparazitler yönünden kontrol edilmiştir. Kontroller vücut yüzeyi, solungaçlar, vücut boşluğu, kan ve kalp, yüzme kesesi, karaciğer, böbrek, sindirim sistemi ve kasları kapsamıştır. Kontrol edilen balıkların türleri, alındığı yer, taşıdıkları parazitler kaydedilmiş olup, kontrol edilen 999 balıktan 597'sinin (%59.7) bir veya daha fazla parazit türü ile enfekte olduğu saptanmıştır.
