Abstract

One of main problems in freshwater aquaculture development in Indonesia, especially in Java, is unavailability of developing zone. It is important to find an underutilized area that meets for industrial scale freshwater aquaculture, i.e. sufficient water supply, wide area, and located in one area or zone. The abandoned mining (sand, tin, etc.) pools distributed along the country might be the potential area for freshwater aquaculture business. For example, there are at least 13 water pools with total surface area of 250 ha at 15 km side of Citarum River in Karawang District (West Java Province). This study was conducted to obtain preliminary data about the prospect and potency of fish culture (tilapia, clariid catfish, and ‘patin’ catfish) in abandoned sand-mining pools in Karawang District. Mini floating net cages of 1 x 1 x 1.5 m3 size were used for culturing fish, i.e. patin catfish (Pangasianodon hypophthalmus), nile tilapia (Oreochromis niloticus), and clariid catfish (Clarias gariepinus), separately. Patin catfish were stocked at a size of 2 g with a density of 300 fish per cage, tilapia were stocked at a size of 6 g with a density of 400 fish per cage, while  the clariid catfish were stocked at a size of 1.4 g with a density of 980 fish per cage. A floating commercial feed (30%—32% protein, 3%—5% fat) was used at a daily rate of 9% biomass weight at the beginning and reduced gradually to 3% at the final culture period. Observed data showed that patin catfish grew from the initial size of 2.08 g to the final size 299.59 g in 5 months, nile tilapia grew from individual initial size of 5.92 g to the final size of 247.12 g in 14 weeks, and clariid catfish grew from initial size of 1.39 g to the final size of 73.10 g in 8 weeks. These three species were technically prospective for aquaculture development in the abandoned sand-mining pools.

Abstract

Organic and inorganic pollutants such as N, P, and heavy metals are a serious problem in water bodies (lake, reservoir, river, and stream) and have deleterious effects to pond productivity and human health. These pollutants produced from anthropogenic activities (i.e. industrial, agricultural, and settlement) are released into the water bodies and causing poor water quality. Constructed wetland (CW) is one of the technologies that have the capability to solve such problems. The purpose of this experiment was to examine the efficiency of constructed wetland in terms of reducing pollutants from the stream as a water resource for aquaculture area and increasing fish production. Two kinds of treatments were set up: one fish pond culture with constructed wetland and the other one without constructed wetland (control). Each treatment consisted of three replications. The result showed that water quality in the fish pond with CW was better than the control. Constructed wetland were able to reduce ammonia (NH3-N), nitrite (NO2-N), nitrate (NO3-N), TN, phosphate (PO4-P), TP, Cu, Pb, and As concentrations to 15.00%-88.27%, 9.52%-72.73%, 11.11%-57.14%, 20%-66.67%, 24.44%-80.77%, 12.04%-77.95%, 50.00%-100%, 56.25%-100%, and 46.83%-100%, respectively. Nile tilapia cultured in pond using CW was higher than the control in terms of total length, body weight, and survival rate. The t test revealed that nile tilapia (Oreochromis niloticus) cultured in pond with CW and the control has significant difference (P<0.01) in terms of total length, body weight, and survival rate. This is the evidence that constructed wetland technology is very useful on improving water quality and increasing pond productivity of nile tilapia cultured in the freshwaterpond.
