Abstract

ABSTRACT Productions and utilizations of organic fertilizers originating from solid waste of super intensive shrimp farms to reduce the amount of wastewater released to the surrounding areas and its environmental impacts, are recommended to support both aquaculture and agriculture industries. This study was aimed to evaluate growth of natural feed (plankton and lablab) fertilized by organic fertilizer originating from super intensive shrimp farm and other different fertilizers. Completely randomized design was applied in this study with four treatments and three replications. The following treatments were urea + SP-36 + organic fertilizers originating from intensive shrimp farm + isolated shrimp ponds bacteria ISO (A), urea + SP-36 + commercial organic fertilizer (B), Urea + SP-36 + chicken manure fertilizer (C) and control, (urea + SP-36) (D). The dosages of fertilizers were: urea 200 kg/ha, SP-36 100 kg/ha, and organic fertilizers (solid waste originating from super intensive shrimp farm, commercial organic fertilizer and chicken manure fertilizer) 2000 kg/ha. The measured variables were species composition and abundance of phytoplankton, biomass of lablab, and water quality. The results of this study indicated that treatments A and B resulted high in number of plankton genera, which was 19 genera, whereas treatments C and D only 10 genera. The highest mean abundance of plankter was found in Treatment A, which was 14,571 ind/L, followed by Treatment B, 9,489 ind/L; Treatment C was 8,717 ind/L and the lowest was found in Treatment D, 5,066 ind/L. The dominant phytoplankton observed in this study was Oscillatoria sp. whereas the most observed zooplankton was Branchionus sp. The mean biomass of lablab produced from solid waste originating from super intensive shrimp farm was 4.35 g/100 cm2 which was not significantly different (p>0.05) from Treatments B and C, yet significantly different (p<0,05) from the control. The water quality variables measured during this study was within the acceptance values for natural feed productions.
