A dynamic model was used to obtain optimal value or amount in the application of paddlewheel. Stella 9.1.4 software programing was employed to find relationships among parameters. The aims of this reasearch was to determine the percentage of oxygen uptake by vannamei shrimp (Litopenaeus vannamei) which is supported by 1 paddlewheel. The result showed that the optimal number of paddlewheel was 1 paddlewheel with Standart Aeration Efficiency was 1,31 kgO2/kWh. The percentage of oxygen absorption on vannamei shrimp until final cultivation was 24% during the cultivation, the percentage of oxygen absorption on vannamei shrimp had increased. In this research, total oxygen demand was 567 ppm, shrimp production was 1054,88 kg, the amount of feed was 2278,1 kg with a pond area was 600 m2, stocking density was 133 PL/m2 during a cultivation period of 98 days.Keyword : Paddlewheel, Oxygen, Vannamei shrimp (Litopenaeus vannamei)

Fish health is an important problem faced by Cantang grouper (Ephinephelus sp.) Hatcheries. Broodstock health management needs to be managed properly so as not to decrease the quality and production of Cantang grouper seeds. Cantang grouper broodstock health management includes the process of maintaining grouper broodstock, feeding, disease control and water quality management. The data collection method is done by recording the results of active participation, interviews and observations. Broodstock grouper cantang are maintained in ponds made of concrete with sizes ranging from 150 meter kibik and a depth of 3 meter. Pond cleaning is carried out once or twice a month with the addition of 2 kg of chlorine / 150 tons of water. Grouper broodstock is fed 10 kg for 24 broodstock. feed in the form of trash fish, squid, mackarel, vitamin C and vitamin E. The types of diseases that often attack grouper broodstock are Criptocaryon irritans, Benedia sp and Vibrio alginolyticus. Water quality parameters measured in grouper broodstock ponds are salinity and temperature. The water salinity in broodstock ponds ranges from 34 - 35 ppt and temperatures range from 27-31 derajat celcius.

Pellet is replaceable with fermented duck manure in the catfish. The effect of substitution pellet feed juvenile catfish with fermented duck manure was investigated. It can be done by fermentation process of duck manure by yeast from traditional food starter called Tape . It contains yeast of genus Aspergilius, Saccharomyces, Candida, Hansenulla , dan Acetobacter bacteria. Catfish diets supplemented with 5% pellet/fish/day (W/W/day). Four treatments diets were 45% (A), 30% (B), 15% (C) and 0% (D) levels of duck manure from total weight and it fed to catfish juvenile (weight 2,75±0,05 g) for 30 days controlled aquaria. The results of this studies found that the recommended diet was diet C and D formulations beacuse it can provide catfish juvenile growth response. Duck manure can replace feed juvenile catfish by fermentation for maximmum 15% from catfish diets.

The raw water is the main water used as a medium carp hatchery process performed by the unit Pengelolah freshwater aquaculture (UPBAT) Pandaan conducted, in this case the raw water is derived from well water and river water. In order to make the program successful that CPIB Central Government digalahkan, this water must be considered and examined since water is the main medium in the vaccination process, and also water is also very susceptible to pollution. But the facts on the ground show that there are still many farmers who are still underestimated and do not pay attention to the heavy metal content in the raw water in the vaccination process of carp. Based on this study, it is necessary to determine the content of heavy metals lead (Pb), mercury (Hg), cadmium (Cd) in raw water for carp fish farming (Osphronemus gouramy). Data recovery method uses appropriate samples. Water samples were taken from 2 different points and analyzed using the AAS method (Atomic Absorption Spectrophotometry). The results of the measurement of heavy metals Pb, Hg and Cd, showing the difference between river water and well water. The content of heavy metals from river water and well water is Pb or 0.0031 mg / l - 0.0033 mg / l and 0.0001 mg / l; 0.0011 mg / L -0.0012 mg / L and 0.00071 mg / L-0.00072 mg / L; Cd 0.0052 mg / l -0.0054 mg / l and 0.0012 mg / l -0.0013 mg / l.

原水是Pandaan Pengelolah淡水养殖(UPBAT)单位进行的中等鲤鱼孵化过程中使用的主要水，在这种情况下，原水来自井水和河水。为了使CPIB中央政府digalahkan的计划取得成功，必须考虑和检查水，因为水是接种过程中的主要介质，而且水也很容易受到污染。但实地事实表明，仍有不少养殖户在接种鲤鱼的过程中，对原水中的重金属含量仍存在低估和不重视的情况。在此基础上，有必要对鲤养殖原水中重金属铅(Pb)、汞(Hg)、镉(Cd)的含量进行测定。数据恢复方法使用合适的样本。从两个不同的点取水样，用原子吸收分光光度法进行分析。重金属铅、汞、镉的测定结果，显示了河水与井水的差异。河水和井水重金属含量分别为0.0031 mg / l ~ 0.0033 mg / l和0.0001 mg / l;0.0011 mg / L -0.0012 mg / L和0.00071 mg / L-0.00072 mg / L;Cd为0.0052 mg / l -0.0054 mg / l和0.0012 mg / l -0.0013 mg / l，水源仍未超过政府质量标准。
