Protozoan Parasitic in Eels (Anguilla spp.) from Lindu Lake, Central Sulawesi

Abstract

ABSTRAKInfeksi 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.Kata kunci: Danau Lindu, indeks dominansi, prevalensi, protozoa parasitik, sidat, tingkat kesukaan organ 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 chisquare test, protozoan parasitic had a different preference to organs of eels.

Article Review: Identifications and Geographic Distribution of Six Anisakis Species (Nematoda: Anisakidae) in Indonesia

“…The results showed that fish from Kupang, Indonesia could cross to Australia but no adult fish moved from Australia to Kupang. The article by Amir et al (2016) and Jabal et al (2020) provides interesting fact regarding the spread of A. simplex. The Anisakiosis case reported by Amir et al (2016) is intriguing since the patient disclosed a history of consuming Empurau fish (Tor tambroides) sushi at one of the Japanese restaurants in Kuala Lumpur two days before to a clinical presentation.…”

“…It was determined to be an A. simplex using COX2 mtDNA PCR scanning, provided more evidence of A. simplex presence in Malaysia. Does this suggest that anadromous fish can spread Anisakis to fish in fresh waters and what is the process of its transmission, considering the fact that of research Jabal et al (2020) found that eels (Anguilla spp.) in the Lake Lindu were infected with Anisakis.…”
