Abstract

African catfish (Clarias gariepinus) is widely cultured freshwater species in Indonesia as well as in Jemirahan, Sidoarjo. Two major problems of catfish culture in this area is low survival rate and low margin due to high cost in feed utilization. The purpose of this activity was to evaluate the application of probiotic and alternative feed in catfish culture. Fish fry of 7-9 cm in size was cultivated for 90 days in rearing activity. All tanks were treated by probiotic during one cycle of culture. Probiotic was directly given to the water and administered by feed. The results showed that survival rates obtained during cultured periods was 92%. Meanwhile, feed conversion ratio value was 1.5. It can be concluded that probiotic application was able to improve the survival rate and the use of alternative feed was able to replace commercial feed.

Abstract

Edwardsielliosis is a disease that commonly infects freshwater fish including catfish (Clarias sp). Edwardsielliosis is caused by Edwardsiella tarda infection and causes mass mortality in catfish farming. Overcoming diseases in freshwater fish can use drugs or antibiotics that are classified as safe and their use is in accordance with government regulations. This study aims to determine the appropriate dosage of Oxytetracycline in catfish infected by E. tarda bacteria through histological analysis. The study design used Completely Randomized Design with 3 treatments, 1 control and 3 replications in each treatment. Catfish used were ± 25 cm in size and the dose of oxytetracycline used were 15, 30, and 45 ppm. The results showed tissue damage edema, vacuolization, necrosis, and haemorhage in fish infected with Edwardsiella tarda bacteria with the lowest damage at 45 ppm of oxytetracycline treatment. The results indicate that oxytetracycline has an effect on muscle histology and recovery of fish health.
