Identifikasi dan Prevalensi Parasit pada Insang dan Saluran Pencernaan Ikan Gurami (Osphronemus gouramy) di Desa Lantasan Lama Kecamatan Patumbak Sumatera Utara

Abstract

Each fish farming activity has obstacles that can cause a reduction in production. The main causes of failure in farming fish’s production are disease and parasites in fish. The research based on identification and prevalence of parasites on the gills and digestive tract (gut) of giant gouramy (Osphronemus gouramy) was done in Balai Karantina Ikan, Pengendalian Mutu, dan Keamanan Hasil Perikanan Kelas I Medan I bagian Parasitologi Desa Aras Kabu, Kecamatan Beringin, Deli Serdang, Sumatera Utara. The research started in july 2014 through the month of September 2014. The research aims to look at the type of parasites that found in gills and digestive tract of giant gouramy (Osphronemus gouramy) by identifying and calculating the rate of prevalence of parasites that were found. The research was conducted by taking 10 samples of giant gouramy (Osphronemus gouramy) that was initiated by decerebrospinal at the head of the fish, then gills organs and the digestive tract (gut) were taken for the identification process. Organ gills and digestive tract (gut) were placed into petridish containing physiological saline 0,85% and identificated by using a microscope. The result shown that in the organs of giant gouramy gills (Osphronemus gouramy) were found parasites Dactylogyrus sp. and with prevalence of 10% in gills organs classified as often category and in the organs of the digestive tract (gut) were found parasites Camallanus sp. of 30% with the prevalence classified as commonly.
