Ectoparasite inventorisation of nilem fish (Osteochilus hasselti) fingerlings cultured on ponds in Sukabumi, West Java, Indonesia

Abstract

Nilem fish (Osteochilus hasseltii) is a type of freshwater fish native to Indonesia that is included in the Cyprinid family and has the potential to be developed as a superior product of aquaculture in Indonesia. This study aims to inventorisation the level of ectoparasite in nilem fishfingerlingscultured on the ponds in Sukabumi, West Java, Indonesia. Ectoparasites examination was carried out by taking mucus from the skin surface and gill of nilem fish. Sample preparations that have been made are observed using a stereomicroscope. Prevalence and intensity levels were analyzed by descriptive analysis. The observation of the sample showed the presence of ectoparasites such as Trichodina sp. (P: 86.67%; MI: 7.69 ind/fish) and Dactylogyrus sp. (P: 6.67%; MI: 1 ind/fish). In summary, the level of prevalence and intensity produced are included in the medium category infestation and the two parasites found cannot pose a zoonotic risk.
