Abstract

The cultivation of super-intensive shrimp with high density has consequences on the burden in the form of waste as the aquaculture activities product affecting the habitat feasibility for the aquatic organisms and the environment of fisheries. Super intensive shrimp in the form of solid waste has the potency to use as the raw material of organic fertilizer. Hence, this research is subject to assess the growth response of live feed and milkfish nursery, which are given super intensive pond solid waste through organic fertilizer compared to commercial organic fertilizers. The research used a completely randomized design (CRD) by three times of treatment and repetitions, respectively. The treatment applied in the experimental group was Urea plus SP-36 plus organic fertilizer originated as of best quality concentrated pond solid waste (A), Urea plus SP-36 plus commercial fertilizer (B), Urea plus SP-36 plus chicken farm waste organic fertilizer (C), and the controls group was Urea plus SP-36) (D). The Urea fertilizer dosage was 200 kg/ha, SP-36 as much as 100 kg/ha, and organic fertilizer each as much as 2,000 kg/ha. The parameters observed were components and a large quantity of plankton, the growth and survival rate of the juvenile milkfish, and the quality of water. The results of this research showed that the number of plankton species obtained during nursery of milkfish was 43 genera consisting of 27 genera of phytoplankton and 16 genera of zooplankton. The most dominant plankton found was from the classes Bacillariophyceae as much as 41.86%. The abundance of plankton obtained ranges of 1.330-1.915 ind/L. The super-intensive shrimp pond solid waste was applied as organic fertilizer along with inorganic fertilizer produced abandon plankton along with growth and survival juvenile milkfish produced by the application of commercial organic fertilizer was better than the components in the control group. This research also found that water quality measurement results during the experiment were suitable for the growth of live feed and milkfish.
