Abstract
Catfish (Clarias sp.) is one of the fresh water fish commodities widely cultivated and very popular in community for being simple in breeding and fast in growth. The demand of people for catfish has led to the increase of production in meeting the demand. This study aimed to analyze the values of SR, RPS, MT and MTD of catfish using the challenge test with bacterium A. hydrophila and given the fatty acid compounds of A. planci. The results of this study showed that the highest average value of SR was found in the treatment with 0.7 mg/kg BBI (26-76%), the highest average of RPS was found in the treatment with 0,7 mg/kg BBI (65%), the lowest average values of MR was found in the treatment with 0,7 mg/kg BBI (23,33%), and the average values of MTD were in the range of 94,24 to 142,67%. Meanwhile, the water quality parameter in the range of the optimum value of DO on day 1 was in the range of 5 to 6,8, on day 7 it was in the range of 5,2 to 6,8, and on day 15, it was in the range of 5,5 to 6. The level of oxygen was at 4 ppm and the water temperature was in the range of 26 to 28°C. The results of the identification towards the fatty acid compounds with GS-MS showed two fatty acid compounds; those are Hexadecanoic acid and 13-Octadecenoic acid. From this study, it can be concluded that there was an effect of giving the injection doses of A. planci compound on the analyses of SR, RPS, MR and MTD in the challenge test with the bacterium Aeromonas hydrophila in comparison to the fish not given with fatty acid compounds of A. planci.
