Abstract

Nile tilapia, whether cultivated or living in the wild, is susceptible to various parasite infection. Parasitology investigation was conducted to identify parasites of Nile tilapia fish in Lakes and from aquaculture facilities. The fish examined from aquaculture facility in Bantaeng has a total length of 15 to 20 cm (n= 30) and the hybrid-tilapia from a mini hatchery consist of three groups of fish size. Fish from Towuti Lake range from 7.0 to 21.8 cm in total length (n= 35), and the fish from Tempe Lake range from 10 to 16 cm in total length (n= 40). Parasite found from Nile tilapia in Tempe Lake was monogenean: Cichlidogyrus spp and Scutogyrus longicornis, and Crustacea- Argulus indicus. Parasites found from Aquaculture facility in Bantaeng were Trichodina sp, Gyrodactylus cichlidarum, Cichlidogyrus spp. and Scutogyrus longicornis. Trichodinids fround from Nile tilapia in Towuti consists of Trichodina centrostigeata, Paratrichodina sp, Trichodina sp., Trichodinella sp., and Tripartiella sp. Parasites found from red hybrid tilapia were Trichodina spp, Cichlidogyrus spp and G. cichlidarum. The prevalence and mean intensity of the parasite^s infection were discussed. In this study, we present for the first time the presence of some genera of Trichodinids in Nile tilapia in Towuti Lake.
