  • 摘要:Koi fish (Cyprinus carpio) is an ornamental fish that is very popular in national and international markets. However, in the cultivation process to produce the best quality, many obstacles occur, one of which is the parasite Myxobolus sp. which are commonly found in Koi Fish (Cyprinus carpio) aquaculture ponds. Myxobolus sp. can cause mass deaths in a short time. Myxobolus sp. also attack organs in tissues that can cause various damage. Many ways have been achieved by cultivators in preventing the spread of these parasites, one of which is the use of probiotics. This study aims to determine the effect of giving probiotics as an effort to manage air quality and determine the effect on histopathological organs in fish as a form of preventing infection with the parasite Myxobolus sp. The method used is a method using control fish, treatment control, and experimental treatment of probiotics with doses of 0.6 ml, 1.2 ml, 1.6 ml in healthy fish and sick fish as treatment 1,2,3,4, 5.6. Sampling of air quality using a DO meter and pH meter while for fish surgery using a sectio set, as well as making microscopic histopathological observations. The results of air temperature quality obtained an average of 25.5oC, an average pH of 8.17, an average of 6.7 mg/l DO. The results of macroscopic and microscopic observations stated that the bacterial isolates in the probiotic Petrofish were species of Bacillus pumilus, Lactobacillus plantarum and Nitrosomonas sp. The results showed that there were changes and tissue damage in Koi Fish (Cyprinus carpio) infected with Myxobolus sp. The conclusion of this study is that the administration of probiotics can affect the air quality in the culture media and affect the histopathological changes of Koi Fish (Cyprinus carpio) tissue.
