Opis: The outcomes confirmed that the medical signs of catfish infected by vibriosis have been redness lesions/ulcers on the body floor, hemorrhagic, fluid inside abdomen, and fin eroded with redness wound. Bacterial identification through biochemical check revealed the causative agent of catfish disease at brackish pond space have been micro organism of the genus Vibrio , Vibrio vulnificus . Frontal method was used to acquire larvae from mirror and scaly carp species. Hydro-chemical and hydro-biological studies of water bodies, institution ... The fry carp rising ponds make up 1,39% of the entire fish pond surfaces, the yung carp ponds 19.92%, and the ponds with consumption fish 77,76%. The whole quantity within the carp ponds with consumption fish 77,76%. Fish ponds are fertilized and fish are additionally fed instantly with oil cake, lupin seeds, and grain husks. In addition, this fish is also cultured as a result of it has a rapid development rate. A high demand of this commodity initiates farmers to do intensive efforts (Elpawati et al., 2015). Whereas for measuring ammonia and nitrate in every pond that's totally different feed, it takes 1 time for 2 weeks. The results of this study indicate that the Study of Water Quality of Sangkuriang Catfish (Clarias sp.) Cultivation of Biona System Feeded by Fementation and Non Fermentation . It could be concluded that the measurement of fine water quality parameters is a pond given fermented feed, as a end result of the water quality meets the Indonesian National Standard of catfish cultivation on an enlargement scale. Quality feed with the best nutrient content material can accelerate the method of fish growth in order that the need for a very large feed operating prices between 60-70% could be anticipated. This research goals to determine the effect of commercial, natural and artificial feed on absolutely the development of weight and survival rate of Sangkuriang catfish . The research was performed for jenis ikan budidaya air tawar forty nine days with 20 catfish seedlings in 12 containers of forty x 20 cm jars with four liters of water volume capacity. The progress of catfish is comparatively fast in order that required a large and high quality feed. Engineering enchancment of feed composition could be via the development of fermented formulation with Effective Microorganisms four with completely different time period to be obtained optimization of protein composition. This analysis used full randomized design 4 remedy three ... The genotypic diversity showed by the hybrid crossbreed of transgenic Mutiara with non-transgenic catfish excessive sufficient in the first offspring. The goals of the research had been to detect genotypic variety from Sangkuriang catfish, transgenic Mutiara, non-transgenic Mutiara and first offspring with RAPD marker using 2 major varieties (OPA-03 and OPA-06).
