Abstract

This study aims to identify ectoparasites and determine the incidence of parasites in Toman fish that are kept in wooden cages in Muara Dua Village, Seruyan Hilir District, Seruyan Regency. The method of this research is the sampling of Toman fish (Channa micropeltes) as many as 60 fish taken from three cages where fish are kept using the survey method. Each fish was observed on the fins, skin and gills and compared the results with the identification key book. From the results of research on Toman fish originating from Muara Dua Village, it was found that 4 types of ectoparites that infested Toman fish were as follows: Ticodina sp, Dactylogrus sp, Oodinium sp, and Ichtyoptirius multifilis and predilection or sites of attack of ectoprasites including fins, skin, and gills with a level value of The incidence of ectoprasites ranges from 42-68%, including in the common and frequent categories.

Analisis Prevalensi Dan Intensitas Ektoparasit Ikan Karapu Tikus (Cromileptes altevalis) Di Keramba Jaring Apung Perairan Teluk Kayeli Kabupaten Buru

Summary

Penelitian ini dilaksanakan di Laboratorium

Bahan yang digunakan sampel ikan Toman (Channa micropeltes ), Akuades, Alkohol 50%. Selanjutnya, pengamatan ektoparasit dilakukan Laboratorium Jurusan Budidaya Perairan, Universitas Darwan Ali. Pemeriksaan jenis ektoprasit yang menginfeksi ikan toman dan menentukan insidensi tiap jenis ektoprasit, maka dilakukan pemerikasan ektoprasit dengan prosedur (Hoffman dan Peralta, 1999) dalam Mulyana (2015) : (1) lendir di kerik dari permukaan tubuh, insang , sisik dan sirip mengunakan scalpel,lalu pisahkan dan letakan di atas preparat, (2) tambahkan setetes akuadest keatas kaca objek berisi lendir, (3) campurkan lendir dengan akuades secara merata, lalu tutup mengunakan cover glass dan (4) preparat ulas basah diletakan dibawah mikroskop. Analisis Data Insidensi ektoparasit yang di temukan pada ikan sampel di hitung menurut rumus Tumbol et al (2011), dan data hasil perhitungan akan di analisis secara deskriptif Sugiyono (2011).
