The potential of mixed epibiotic (binahong leaves, anrederacordifolia, and garlic, allium sativum, extracts) as a feed additive to combat aeromonashydrophilainfection on catfish (clariasgariepinus)

Abstract

Catfish are one of the most commercially important fish cultured and consumed in Indonesia. Catfish (Clarias garipienus) is one of the most commercially important freshwater fish cultured and consumed in Indonesia. However, Motile Aeromonas Septicemia (MAS) disease was caused by Aeromonas hydrophila is one of the obstacles which are often to be found during the culture. This study aimed was to determine the epibiotic extracts of binahong leaves (BLE) and garlic (GE) as a feed additive on the growth performance and survival rate of catfish against Aeromonas hydrophila infection. This research was conducted with Completely Randomized Design (6 treatments and 3 replications)in the aquaculture department laboratory, Fisheries and Marine Science Faculty of Diponegoro University. The treatments were various dosages of the mixture of epibiotic extracts, namely A (2.500 ppm BLE+0 ppm GE), B (1.875 ppm BLE+250 ppm GE), C (1.250 ppm BLE+500 ppm GE), D(625 ppm BLE+750 ppm GE), E (0 ppm BLE+1.000 ppm GE) and K (0 ppm BLE+ 0 ppm GE). The result of the research indicated that a mixture of epibiotic was able to increase the survival rate but not in the growth rate. This treatment also was affected by the blood profile of cat fish ie. Erythrocyte, leucocyte, and hemoglobin These results showed that the best dosage of a mixture of epibiotic extracts (1.250 BLE+500 ppm GE) resulted in 86,67% of survival rate.
