ABSTRAK

Infeksi protozoa pada ikan sidat (Anguilla spp.) asal Danau Lindu memengaruhi berat ikan dan kesehatan ikan. Pemeriksaan parasit pada ikan sidat, yaitu koleksi ikan sidat, pemeriksaan ikan, observasi, pengukuran, identifikasi parasit, dan pewarnaan protozoa menggunakan giemsa. Keragaman protozoa parasitik adalah Myxidium sp., Myxobolus sp., Chilodonella sp., Ceratomyxa sp., Balantidium sp., Henneguya sp., dan Glugea sp. Prevalensi tertinggi, yaitu Myxidium sp. sebesar 77% pada ikan sidat dan tidak ada protozoa yang mendominasi di antara parasit lain. Berdasarkan uji chi-square protozoa memiliki perbedaan tingkat kesukaan pada organ ikan sidat.

ABSTRACT

Infection protozoan parasitic on eels (Anguilla spp.) from Lindu Lake was affected weight eels and health eels. The protozoan parasitic examinations were collection of eels, inspection eels, observation, measurement, identification of parasites, and staining protozoan used giemsa stained, trematode used semichons’s acetocarmine stained and nematode used clove oil and KOH. The diversity of parasitic protozoan found such as: Myxidium sp., Myxobolus sp., Chilodonella sp., Ceratomyxa sp., Balantidium sp., Henneguya sp., and Glugea sp. The highest prevalence Myxidium sp. in eels was 77% and no protozoan dominated between other parasites. Based on chi-square test, protozoan parasitic had a different preference to organs of eels.

Keywords: dominance index, eels, level of preference organs, Lindu Lake, prevalence, protozoan parasitic
