This research was aimed to know the effect of different fermented organic feed on the growth performance of Oithona sp. in semi-mass culture condition. The Oithona sp. cultures were fed with mixed organic fermentation of pulp, bran and fish meal by using probiotic microbes and phytoplankton cells. There were 4 treatments and 4 replicates. Treatment A was the Oithona sp. cultured with added Chaetoceros calcitrans cells without fermented organic feed (0 g ∙ L–1 of medium culture). While B, C, and D were added with the same numbers of that C. calcitrans cells of 2x106 cells ∙ mL–1 and 0.5 g ∙ L–1, 1.0 g ∙ L–1, 1.5 g ∙ L–1 of fermented organic feed, respectively. The results showed that the dosage of fermented organic feed had significantly different effect (P < 0.05) on the growth performance of Oithona sp. culture. The best growth performance of Oithona sp. showed by adding 0.5 g ∙ L–1 of fermented organic feed, with total density of 7.09 ± 0.11 ind ∙ mL–1, population growth rate of 0.116 ± 0.002 ind ∙ d–1 and eggs production of 7.88 ± 0.93 eggs ∙ ind–1 of adult.

The white spot syndrome virus (WSSV), the causative agent of White Spot Syndrome Disease (WSSD), is a major shrimp pathogen in Indonesia. Dendronereis spp. is a ubiquitous Polychaetes and natural food of shrimp raised in brackishwater pond in Indonesia. The objective of this research is to determine the occurrence of WSSV and the viral load in Dendronereis spp. obtained from the shrimp pond. Dendronereis spp. was obtained with PVC (10 cm in diameter) from a traditional shrimp pond in Semarang vicinity. As a comparison, healthy looking Penaeus monodon was also obtained from the same pond. The occurrence of WSSV in Dendronereis spp. was determined with 1-step and nested PCR using primer for WSSV major envelope protein, VP 28. The viral load was counted with 1-step Real Time PCR. The WSSV was detected in Dendronereis spp. with 1-step and nested PCR. The point prevalence of WSSV infection in Dendronereis spp. is 90 %. The viral load ranged from 0 to 1.9 x 104 copy of DNA/µg total DNA. The viral load in Dendronereis is comparable with that of naturally infected and at carrier state P.monodon from the same pond. This is the first report of WSSV load in naturally infected Dendronereis spp.

The Effect of enrichment culture media through the combination of fermented tofu waste, rice bran, chicken manure to increase the production and quality of silk worm, Tubifex sp. was studied in this research. The experiment method was employed in this research by using complitely randomized design pattern with four treatments and three replicates, respectively. Those treatments were the combinations of 0% tofu waste, 0% rice bran, and 100% chicken manure (A), 35% tofu waste, 15% rice bran, and 50% chicken manure (B), 25% tofu waste, 25% rice bran, and 50% chicken manure (C), and 15% tofu waste, 35% rice bran, and 50% chicken manure as D treatment. The results shown that the enrichment culture media through the combination of tofu waste, rice bran, and chicken manure were siqnificantly effect (p<.05) on the total biomass production and protein content, but no siqnificantly effect on the total length growth of silk worm, Tubifex sp. However, the combination of 35% tofu waste, 15 rice bran, and 50% chicken manure was the best production and quality of silk worm, Tubifex sp.Key word : Tubifex sp., agriculture organic wastes, fermentation, quality, and culture production

Dumbo catfish (Clarias gariepinus) Sangkuriang strain is the consumption of freshwater fish that is much favored by many people, because its high nutrition and low price. The high price of feed and the low efficiency of feed utilization are an obstacle in the development of African catfish cultivation. The purpose of this study was to determine the use of agricultural product wastes such as corn flour, wheat, soybean meal, curry and chicken eggs that have been made as pellet feed containing 32.58% protein, with the addition of probiotics (A) and without the addition of probiotics (B) on the efficiency of feed utilization, growth and survival of African catfish (C. gariepinus).This study used an experimental method by designed through a completely randomized design (CRD) with two treatments and each of three replications, respectively. The test fish seed used was African catfish (C. gariepinus) with an average weight of 2.04 ± 0.05 g and an initial density of 350 tails / m2 of pond area with a culture period during 60 days. The results of this study that self-made feed with material from agricultural wastes were sufficient to provide the results of the value of feed utilization efficiency (FUE) of 84.10 ± 1.83%, feed conversion ratio (FCR) of 1.03 ± 0.02, and survival rate (SR)of 95.79 ± 0.16%. The addition of probiotics to self-made feed with raw materials from agricultural wastes had a significant effect (p <0.05) to produce feed utilization efficiency (FUE)of 99.56 ± 5.64%, feed conversion ratio (FCR)of 0, 88 ± 0.04, relative growth rate (RGR) of 14.77 ± 0.66% / day, and the survival rate (SR) of 98.92 ± 0.29%, which has a higher value than feeding without probiotics.

The experiment to determine the best salinity on media for the efficiency of use of Catfish (Clarias gariepinus) strain Sangkuriang’sfeed and growth. Laboratory experimental was used with various salinity variable were: 0 ‰ (as control), 1 ‰, 2 ‰, 3 ‰, 4 ‰ and 5 ‰ with 3 repetitions for each. 3% for fish weight feeding on twice a day at 8.00 am and 6.00 pm. The result of this research showed that cultured at plastic pond media with different salinity do not have an effects (p > 0,05) to feeding efficiency and daily growth rate of Sangkuriang’s strain of lele dumbo (Clarias gariepinus var.), but it has a significant effect (p<0,01) to absolute biomassa growth, feeding conversion and survival rate. Cultured Sangkuriang’s lele dumbo in plastic pond could be efficiently conducted at media’s salinity up to 5 ‰, but by significant notice at frequency, type and nutritional composition of feeding and also controlling the water quality. The most appropriate optimal salinity value, based from growth of compensation for the rearing of consumption size, is 4 ppm. The water quality showed on supporting life of lele dumbo lele’s cultured in plastic pond.Keyword: Feed, Growth, Sangkuriang’s catfish, salinity, Plastic pond

Asian seabass (Lates calcarifer) is an economically important euryhaline fish. Feed absorbs 60–70% of the total production costs; therefore, regulating feeding frequency is necessary to increase feed utilization efficiency. Feeding frequency is the amount of feed given to fish daily. This study aimed to examine the effects of feeding frequency on the utilization of a phytase enzyme in the feed of Asian seabass fingerlings. The experimental fish used were Asian seabass fingerlings (7.57±0.28 cm in length and 5.31±0.15 g in weight) with a stocking density of one fish/L. This research used an experimental method with a completely randomized design (CRD), which consisted of four treatments and three replicates. The treatments were feeding frequencies of 1 (A), 2 (B), 3 (C), and 4 (D) times a day with the addition of 0.1 g/kg feed of the phytase enzyme. The feeding method used was the relative feeding rate, and the feed dose was 6% of the fish biomass. The results showed that feeding frequency significantly affected total feed consumption (TFC), feed conversion ratio (FCR), feed utilization efficiency (FUE), protein efficiency ratio (PER), and relative growth rate (RGR). However, they had no significant effect on the survival rate (SR) of Asian seabass fingerlings. Treatment C (3 times a day) showed the highest TFC, FCR, FUE, PER, and RGR, which were 251.85±1.61 g, 1.45±0.03, 69.08±1.50%, 1.51±0.03, and 3.90±0.11%/day, respectively. The water quality in the study area was suitable for Asian seabass cultivation. This study concluded that feeding three times a day resulted in the best FUE and RGR of Asian seabass fingerlings.
