Abstract

Motile Aeromonas Septicemia (MAS) is one of the bacterial diseases that attacks and causes mass death of nile tilapia. Disease control in fish farming using synthetic antibiotics has caused problems in aquaculture, such as bacterial resistance to antibiotics, drug residues in fish, and water pollution. Therefore, alternative measures to control MAS that are safe and environmentally friendly, such as the application of immonostimulant that use organic ingredients, are needed. This research aims to determine potency of immunostimulation of nile tilapia trough feeding of synbiotic feed namely prebiotic Eleutherine bulbosa powder (Ebp) and probiotic containing Lactobacillus casei and Saccharomyces cerevisiae as for prevention MAS disease. The fish were reared for 21 days, in reared for the first 14 days, the fish were given synbiotic feed then for the next 7 days they were given feed without synbiotics. The fish were challenged with Aeromonas hydrophila on day 15th. Experimental design used was completely randomized design with four treatments: 0 g Ebp and 0 ml probiotics in 1 kg of feed (synbiotic free feed), 7.5 g, 10 g, and 12.5 g Ebp each with 15 ml probiotics in 1 kg of feed. The results showed that feeding the fish with synbiotic feed, especially the treatment Ebp12.5, give significantly different results on parameters prevalence, fish recovery, survival rate of the fish test. This research concluded that treatment of Ebp 12.5 was the best dosage of immunostimulant to prevent MAS disease in nile tilapia.

Abstract

Aeromonas hydrophila is a pathogenic bacterium that frequently attacks, causes death, and harms catfish farmers. The continuous use of antibiotics for disease control has been shown to have negative impacts on pathogenic bacterial resistance, antibiotic residues in fish, aquatic environmental pollution, food safety, and causes allergies in human consumers. The use of phytopharmaceuticals is known to be more environmentally friendly and sustainable because they contain active compounds that are more easily degraded, thus leaving no synthetic antibiotic residues in fish tissues and water. This research aimed to determine the effect of black turmeric (Curcuma aeruginosa Roxb) rhizome ethanol extract on treating A. hydrophila infection in catfish. Fish were raised for 14 days. For the first seven days, they were kept under normal conditions. On day 7, the fish were infected with A. hydrophila. On day 8, the diseased fish were immersed in black turmeric rhizome ethanol extract. The experiment used group randomized design with treatment of control or without black turmeric extract (BT0), 35 mg/L, 40 mg/L and 45 mg/L black turmeric extract (BT35, BT40, and BT45). The result showed that treatments were not significantly different (P>0,05) on recovery rate, survival rate, and WBC, but significantly different in hematocrit percentage (P<0,05). The highest of fish recovery rate and survival rate (100%) were obtained in BT40. This research concluded that immersion dosage of 40 mg/L black turmeric rhizome ethanol extract could treating catfish infected with A. hydrophila.
