Abstract

Utilization of swamp area as a fish culture location will cause a decrease in water quality. Therefore, it is necessary to improve the water quality with environmental friendly of biological treatment, one of addition is microbes as probiotics in media culture. The purpose of this research was to determine the combination of microbes from swamps that can improve the water quality of media culture and production of swamp fish culture. The research used Completely Randomized Design (CRD) factorial with two factors consisting of the first factor with two treatments and the second factor with five treatments and three replications. The first factor is without the addition of nitrification bacteria (PROBAC) (N1) and the addition of nitrification bacteria (PROBAC) 5×106 CFU.mL-1 (N2). The second factor is without the addition of swamp microbes (P1), addition of Chlorophyta (3.43×107 sel.L-1) and Bacillus sp. (105 CFU.mL-1) (P2), addition of Chlorophyta (3.43×107 sel.L-1) and Streptomyces sp. (105 CFU.mL-1) (P3), addition of Chlorophyta (3.43×107 sel.L-1), Bacillus sp. (105 CFU.mL-1) and Streptomyces sp. (105 CFU.mL-1) (P4). The result showed that the addition microbes from swamps with combination of N1P4 able to improve the water quality value better than treatment without the addition of mikrobes (N1P1) and only the addition of nitrification bacteria (N1P2). Combination of N1P4 produces the best survival rate of 63.94%, feed efficiency of 59.65%, absolute weight growth of 2.32 g and absolute length growth of 2.27 cm.
