This study was conducted to analyze the production of freshwater Spirulina sp. cultured with photoperiod manipulation treatment. In this study, photoperiod manipulation treatment performed on cultured spirulina using fiber tanks (100 L). Spirulina was grown with different photoperiod (bright/T and dark/G) that are six hours per day (6T-18G), 12 hours per day (12T-12G), 18 hours per day (18T-6G), and 24 hours per day (24L-0G). The parameters were observed include dry biomass, population density (N), specific growth rate (SGR), doubling time (G), proximate analysis, and water quality. The results of this study showed that the optimum population density was achieved on day-3 days of cultured, and manipulation photoperiod showed no significant effect to the dry biomass harvest and population density, but significantly affect the specific growth rate and doubling time. Treatment of lighting 12, 18 and 24 hours per day to produce the maximum specific growth rate (0,345 to 0,366 per day) and a maximum doubling time (1,89 to 2,01 days) were not significantly different, whereas the old treatment six hours per day lighting showed the lowest maximum growth rate (0,323 per day) and highest doubling time (2,15 days). At treatment of lighting 12 hours per day, relatively higher protein content (39,73%) than others. In conclusion, the lighting 12 hours per day resulted in optimum production efficiency than other treatments.Keywords: Spirulina sp., photoperiod, density, biomass, growth, nutrition value.

ABSTRACT A series of experiments was performed to analyze protein digestibility, ammonia excretion, and also heterothropic bacteria and phytoplankton dynamics in the catfish Clarias gariepinus culture. In the digestibility experiment, catfish with an individual initial size of 43.67±0.83 g were stocked into 120 L conical fiberglass tanks at a density of 20 fish per tank. Fish were fed on with commercial diet supplemented with Cr2O3 indicator at a concentration of 1%. In the ammonia excretion experiment, catfish with an individual size of 111.6±9.5 and 40.6±3.4 g, respectively, were placed into a 10 L chamber filled with 8 L of water. Total ammonia nitrogen (TAN) in the chambers were monitored every hour for six consecutive hours. In the bacteria and phytoplankton dynamics experiment, catfish were stocked in the 25 m2 concrete tanks which was divided into two compartments (catfish 10 m2, and heterotrof compartments 15 m2). Catfish with individual size of 42,5±0 g were stocked into the tanks at a density of 100 fish per tank. Water was recirculated from catfish compartments to heterotrophic compartments. Fish were fed with floating feed. Molasses as carbon source for heterotrophic bacteria was applied daily. The experiment was conducted for six weeks. The results showed that the protein digestibility was 61.97±7.24%. Larger fish (size of 111.6 g) excreted ammonia at a rate of 0.008±0.003 mg TAN/g fish-weight/hour, which was lower than that of the smaller catfish (size of 40.6 g), i.e. 0.012±0.004 mg TAN/g fish-weight/hour.

ABSTRACTGiant gourami Osphronemus goramy Lac. is one of the most important fresh water fish commodities with increasing production level every year. Water quality management through a proper water exchange both in quantity and quality can be one of the alternatives to support the elevating production. This research was conducted from July to August 2010 at the Aquaculture Production Technology and Management Laboratory, Department of Aquaculture, Faculty of Fisheries and Marine Science, Bogor Agricultural University. The juvenile used was 0.84±0.011 cm in length and 0.017±0.001 cm in weight which reared in nine units of aquaria with a size of 60×29×33 cm3. Silk worm was used as the feed and provided daily at satiation. Water exchange was performed twice a day at a level depending on the treatment, namely 75% (50% at morning and 25% at evening), 100% (50% at morning and evening) and 125% (75% at morning and 50% at evening) of total water volume. Water exchange at 75%, 100%, and 125%/day resulted in survival rates of 94.11±0.63%; 91.89±2.02%; and 93.89±0.75%; specific growth rates of 7.43±0.15%, 8.58±0.24%, and 9.97±0.18%. Growth rate in length of 1.06±0.06 cm, 1.33±0.04 cm, and 1.55±0.01 cm; coefficient of variation in length of 11.31±1.43%, 9.35±1.46%, and 6.90±2.30%; feed efficiency of 12.47±0.30%, 14.32±1.05%, and 19.67±0.54%. The financial benefits resulted of the process were worth of IDR.351,903.00; IDR.402,302.00; and IDR.464,715.00; whereas R/C ratio of 1.71; 1.80; dan 1.90; BEP of 1,845 unit, 1,645 unit, and 1,517 unit; payback period (PP) of 0.97 years, 0.85 years, and 0.74 years; and the cost production as much as IDR.79.90; IDR.82.70; and IDR.82.90/individual, respectively. The treatments were significantly different on several parameters, such as specific growth rate, length of growth rate, feed efficiency at p<0.05. The results of this experiment showed that 125% daily water exchange improved the production performance of giant gourami juvenile cultured at a density of 20 fish/L. For production purpose, rearing giant gourami fish 2 cm in size at a density of 20 fish/L was found as the optimum condition through 125%/day water exchange.Keywords: water exchange, survival rate, growth, gourami fishABSTRAKIkan gurami Osphronemus goramy Lac. merupakan salah satu komoditas penting ikan air tawar dengan produksi yang cenderung meningkat dari tahun ke tahun.

The highest density of sludge worm, i.e. 421,145 ind/m2 with total biomass of 1,497.80 g/m2, was obtained on the treatment of C/N ratio at 20 (P <0.05). Keywords: Oligochaetes, C/N ratio, tapioca starch, recirculation system ABSTRAK Penelitian ini bertujuan untuk meningkatkan produktivitas cacing sutra (Oligochaeta) pada sistem budidaya dengan memperbaiki kualitas substrat cacing menggunakan penambahan tepung tapioka sehingga mencapai rasio C/N 10, 20, dan 30. Substrat yang digunakan yaitu campuran lumpur tanah dan kotoran ayam dengan perbandingan 1:1 pada wadah budidaya berukuran 100×12×15 cm3. Sistem budidaya yang digunakan yaitu sistem resirkulasi. Cacing dibudidayakan pada padat penebaran 150 g/m2. Hasil menunjukkan puncak populasi dan biomassa cacing sutra terjadi pada hari kesepuluh. Kepadatan cacing tertinggi, yaitu 421.145 ind/m2 dengan biomassa 1.497,80 g/m2, diperoleh pada perlakuan penambahan tepung tapioka dengan C/N rasio 20 (P<0,05). Kata kunci: cacing sutra, rasio C/N, tepung tapioka, sistem resirkulasi
