Removing eggs from red nila female during spawning period were observed to know an appropriate time of removal and its effect on inter-spawning period of female broodstock. Spawning experiment was conducted with three replicates in the hapa. The female that cared fertilized eggs were cathed on 7th day, 21th, 28th day, and 35th day after stocking. Other spawning experiment with three relications were cared out to test the effect of removing eggs. On 7th day after spawning produced the highest number of spawned female reduced yhe inter-spawning interval, but there was no effect of male stocking on re-spawning rate of female. The low number of eggs per spawner together with asynchronus spawning would be problems faced on mass production of red nila seed.

The objectives of the research were to know the production of hatchery, survival rate and growth rate of fry. Floating nets were made for plastics hapa (2 mm mesh size) with 3 different size (5 m2, 10 m2, and 15 m2). The larvae were stocked in different hapa nursery size ( 1 m3, 2 m3, 3 m3) at the rate of 1000 larvae/m3 of water. The fry produced from the first nursery were subsequently reared in waring (mesh size 0,04 cm) at density of 600 fry/m3 of water. The spawning were conducted for 6 months, while larvae rearing were 2 months for each period respectively. The result showed that the hatchery of 15 m2 scale were technically and biologically feasible. During 6 months period it produced 11,870 fingerling of 40 gram, 3,028 fry of 4 gram and 4,290 of larvae. The survival rate and growth rate of fry water not significantly affected by different hapa size either in the first and second nursery. The survival rate of the first nursery was 64.70-72.63% of 5.0-6.8 cm fry, while the second nursery was 97.29-98.30% of 11.5-12.4 cm fry.

Artificial incubations of red tilapia eggs and fry were conducted in the effort to increase fish seed production and its quality. These experiments were done to determine suitable water temperature for egg incubation and larvae rearing. Four different water temperatures, 24, 27, 30, and 33oC with variance 1oC and ambient temperature were tested in triplicates. One liter of plastic incubators made from soft drink bottles were set to water re-circulation system and provided with filter means.The fertilized eggs were stocked at 150 eggs. The hatching rate of egg increased as the increase of water temperature. The increase of water temperature decreased the incubation time of eggs, but increased hatching rate and the growth of larvae. The optimum water temperature was 29,87oC.

Plankton monitoring were conducted in hatchery and rearing hapas of red tilapia (Oreochromis sp.) to know plankton abundance and its utilization by fish during 98 days. Be-weekly plankton samples and fry fish guts were taken from fish hapa rearing, meanwhile brood fish gut were taken monthly. Be-weekly plankton and water monitoring were also applied in fish rearing without feed, water outside of hapas and river. Two units of bamboo frame, 6 x 6 m2 divided into 4 blocks respectively, were used for fixing 2 x 3 x 1 m3 hatchery hapa, and 1 x 2 x 1 m3 rearing hapa. Commercial feed was given daily to brood stock at the rate of 2% of the total fish weight and fry at the rate of 40%. Plankton density and composition in hatchery and rearing hapas were higher density than water reservoir and river. All size of red tilapia consumed selected plankton species, about 31.34-38.89% of existing species. Dominant plankton in hapa water were: Navicula, Closteriopsis, Sphaerocystis, Surirella dan Arthrodesmus and among them were prefered by red tilapia as natural food, namely Navicula, Surirella, Closteriopsis dan Sphaerocystis. Water quality parameters were still suitable for fish growth and breeding, but dissolved oxygen tended to low due to high plankton abundance.

The aim of this research was to find out the effect of waste collection in red tilapia culture using floating net cage to the quantity of the waste and degradation rate, on survival and growth rate of fish. A completely randomized design was performed in the experiment consist of two waste collections; namely: with and without collection, and three fish stocking weights of 2.5 kg, 5 kg and 7.5 kg fish/cage, with two replicates each. Floating net cages with the size of wide, length and height of 1 x 1 x 1.2 m were used in the experiment. To collect fish waste, inverted cone-shape plastic collector was attached to the cage and hanged 15 cm below the cage. Fingerling size ranged from 50 – 70 gram/fish were divided into two groups and stocked in the different replication. The fish were cultured for 84 days and fed daily with commercial feed (25-27% protein content) at the rate of 3% fish body weight. Waste sample were collected and incubated in different temperature of 20, 25 and 30 oC with deviation of 1 oC and 3 replicate each. Parameter of total dissolved solid (TDS), total suspended solid (TSS), DO, BOD, CO2 and NH3 were checked every 5 days for 20 days, and total N and total P were check at the beginning and the end. Data were analyzed statistically using confidence level of 95%. Total waste collected were ranged 0.109-0.117 kg dry weight/cage and waste lossing due to fixing collector 15 cm under the cage was about 14.44%. The addition of waste collection in fish culture tended to make lower survival and growth rate, meanwhile more stocking weight may increase fish harvest. Fish waste decomposed faster in higher temperature, indicate that the waste decomposition could decrease water quality and increase concentration of N and P nutrients.

The aim of this study was to determine the preference for plankton as natural feed by giant gourami, walking catfish, and red nile on intensive aquaculture system. The study was designed using Completely Randomized Design (RAL), with two replications. Each fish was kept in six concrete tanks with dimension 2x2x1 m³ and 60 cm water level. Water source were from wells. Commercial pellet feed was given in three times daily ad libitum. Water samples were filtered and two individual fish were collected for plankton samples from pond water and alimentary canal, respectively, every two week, simultaneously with water quality measurements. Plankton samples were preserved using 5% formaldehyde and was observed under a compound light microscope with 100x magnification. The amount of plankton in the alimentary canal was converted to volume. Data were analyzed descriptively. The result showed that the volume contents proportion of plankton in the alimentary canal was less than 1%. The volume of plankton proportion in the alimentary canal of red nile were found the most than other fish. Each fish had the same preference of plankton of Lepocinclis and Scenedesmus, but different from other species of plankton. The plankton that utilized by giant gouramy were Crucigenia, Diadesmis and Navicula, whereas walking catfish was Pediastrum, and red nile was Microcystis. The plankton that preferred by giant gouramy were Crucigenia, Oscillatoria, Splirullina, and Synedra, walking catfish was Navicula, while red nile were Chrysamoeba and Tintinnidium.

Survival rate and immunity of white leg shrimp ((Litopenaeus vannamei) postlarvae against acute salinity stress were evaluated in indoor experimental trials. The research was conducted with 2x2 factorial design with two levels of aeration (microbubble and macro bubble) and two levels of diet (with and without probiotics) resulting four treatments in triplicate: application of microbubble with gut probiotics (MiP), without gut probiotics (MiC), and macro bubble with gut probiotics (MaP) and without probiotics (MaC). White leg shrimps measuring 7.6 g were maintained in the tanks for 60 days and fed five times a day at a dose of 5% biomass. Harvested shrimp were tested for low salinity stress (5 ppt) for 3 hours. Glucose level, total protein, bactericidal activity, natural agglutination, phenoloxidase, respiratory burst, and superoxide dismutase activities in the hemolymph and the shrimp survival rate (SR) were analyzed before and after the stress tests. Although all examined parameters remained the same between groups before the stress test, significant differences were found among them after the stress test. Microbubble aeration obtained stabilization of hemolymph glucose level, best survival rate, bactericidal activity, and agglutination activities. No significant effect was resulted by the dietary probiotic treatments, but the interaction with aeration treatments revealed the importance to compensate shrimp survival rate when microbubble aeration is unavailable.
