Abstract

Catfish have become an important contributor to fish production in Indonesia. Catfish consumption in Indonesia always increases every year. To meet the demand for catfish consumption, it was carried out with an intensive aquaculture system. However, the high cost of feed has been identified as a significant constraint in catfish farming. Efforts to increase catfish growth are needed to reduce feed costs, one of the efforts is by probiotic supplementation through the feed. This study was carried out to determine the best dose of probiotic rabal dried addition to increasing catfish growth. The experiment used four treatments and three replications. Probiotic rabal dried doses: 0% of feed (A)/feed (control), 5% of feed (B), 10% of feed (C), and (D) 15% of were used as treatment. The feed was given ad-satiation with a frequency of feeding three times a day. Observations were made for 45 days. The results indicated that the B treatment of 5% of feed gave the best absolute weight growth and feed conversion ratio. While catfish fish survival rate was not significantly different on all treatments.

Abstract

Catfish is one of the important fish commodities in Indonesia. There is some problem that becomes trouble in catfish culture, and the most trouble which cause losses in catfish culture is a disease, especially motile aeromonads septicemia (MAS). The purpose of the study was to analyze the effectiveness of giving dry rabal probiotics for the prevention of motile Aeromonas septicemia (MAS) in catfish (Clarias sp.). This experiment consisted of four treatments, namely catfish farming with the addition of dry rabal probiotics with concentrations of 0%, 5%, 10% and 15%. Catfish (6.03±0.38 g) were reared in a rearing tank with a volume (41x50x57 cm) with a density of 15 fish/aquarium for 50 days. Probiotic bacteria were given daily through feed, while the pathogenic bacteria A. hydrophila was infected on day 51. The results showed that the treatment of giving dry rabal probiotics through feed was effective in improving the immune, and increasing the survival of African catfish. The 10% (C) rabal probiotic treatment gave the best results with the highest survival rate of 75.56 ± 3.85%.
