Abstract

Channa striata is the one of the local comodity in West Kalimantan Province which has important economic value. The demand for Channa striata comes mostly from urban communities, while urban areas only have narrow land / yard. One of the techniques of fish cultivation in narrow land is the aquaponics system. Thus, Channa striata cultivation with the aquaponics system can increase the productivity of cork fish in urban areas. The purpose of this study was to obtain the optimal amount of stocking density in Channa striata culture with an aquaponics system with indicators of success namely survival and growth rate. This study lasted for 75 days, taking place at the Pontianak City Fish Agribusiness Farm. The study design used a Completely Randomized Design (CRD) with 4 treatments and 3 repetitions, The stocking solid treatment used in this study is A: 40, B: 60, C: 70, and D: 50 tails / m2. The results showed that treatment A had a significant effect on the absolute growth rate of 12.85 gr followed by perlkuan D: 12.46 gr, B: 8.87 gr, C: 7.9 gr, while the best specific growth rate was needed at time A: 3.50%, D: 3.44%, B: 3.05%, C: 2.91%. The observation of life survival also has the same trend, namely the best treatment in treatment A: 95%, D: 90%, B: 70%, C: 49%. From the results of these studies it can be concluded that the higher the stocking density in aquaponics fish farming systems will have an impact on the growth rate and the survival rate of Channa striata with the best treatment, namely with stocking density of 40 fish / m2.

Abstract

The most important factor in speeding up fish depends on the food given. The feed given was in the form of artificial feed (pellets) because of the practicality of its availability. However, commercially made feed was of course more expensive, and can pollute the air compared to natural feed which was easy and can be in the surrounding environment. For this reason, it was necessary to look for natural feed as an effective and efficient alternative feed to ripen the gonads of male and female swordtail. The research used a completely randomized design with 4 treatments and 3 repetitions and arranged randomly. Treatment by giving different natural food to the broodstock swordtail: treatment A (commercial pellets), B (Daphnia/Moina), C (blood worms) and D (mosquito larvae feed). Each broodstock treatment used was 27 females and 9 males (ratio 1: 3). The results of water quality measurements of all treatments with an average DO 4 mg/L, temperature 26 to 27oC, pH 7-8 and 30 mg/L hardness, thus showing the water quality during the research, the water condition was suitable for the maintenance of broodstock of swordtail, so that it supported growth. and breed of swordtail to produce tillers. The results showed that the highest average birth rate of swordtail broodstock produced in treatment D were 141 fish followed by treatment B 125 fish, then treatment C of 117 fish. and the lowest was in treatment A with a birth rate of 102 fish.
