Abstract

The aims of this study was to get local raw material of feed fish  able to improve growth anddevelopment of gonads  and composition of the artificial feed and feed supplement that can improvethe reproductive performance of gouramy fish. The method used is the method of completelyrandomized. The research was used completly randomized design with four  treatments and fourrepetition. The treatmens tested were four kinds, pellet commercial (60%) additional sprouts mungbean (Phaseolus radiatus L), fruit peel papaya (Carica papaya) and cabbage (Brassica oleracea L) by40%, and a pelleted commercial (100%) as control. Absolute growth ranges from 6-425 g, the relativegrowth of 3.7 to 22.1%, the growth day 1-7,1 g / day, feed efficiency from 7.8 to 29.33%, GSI 0.1 to1.1% and HSI 0.8 to 1.7%. Temperatures ranging from 23- 31,5⁰C, pH 6.6 to 7.5, Oxygen 5.0 - 6.2ppm , ammonia  0 - 0.25 ppm. Supplemental feed mixture (40%) and commercial pellets (60%) canimprove the growth and reproductive performance brood gouramy. Results of measurement oftemperature, pH and ammonia still qualify live gouramy.Keywords : alternative fish feeds, brood, Osphronemus gouramy

Abstract

The main problem caused by African catfish farmers is the input production inefficiency, namely the use of feed. The productivity and profit margins it produces are very low. Another problem with feed inefficiency that arises is the remaining feed at the bottom of the pond and can eventually cause toxins and even death in fish and production failure. One effort that needs to be done is to engineer biofloc technology. Biofloc technology in catfish farming is very important to be transferred to the fish farmers community. The purpose of this activity is to improve the knowledge, skills, and income of fish farmers. The method used is technology transfer, plot demonstration, and implementation of science and technology. The results show that the farming community is enthusiastic and trained in mastering biofloc technology. Its productivity reaches 568 Kg with high density and FCR reaches 0.7 and net profit reaches Rp. 2,850,000.

Abstract

This study aims to determine the effect of differences in fish density and media volume on the growth and survival of tilapia (Oreochromis niloticus) and to determine the effective density in aquaponic culture using bed media techniques. In this study, parameters were measured including the specific growth rate of fish, feed conversion ratio, water quality and survival rate. The experimental design used in this study was a completely randomized design (CRD) with 4 treatments (1 fish stocking ratio/L media bed; 2 fish/L media bed; 3 fish/L media bed; and 4 fish/L media bed). ) and was repeated three times in this study. The results showed that the average length of the final fish was between 6.5 – 9.5 cm, and the average weight of the final fish was in the range of 5 – 17 grams. The optimum density value and the best fish productivity from this study were at P4 with a stocking density of 20 fish per liter of water with significant results.
