POTENSI TUMBUHAN BANGKAL (Nauclea Orientalis) UNTUK PENGENDALIAN BAKTERI Aeromonas Hydrophila
Get PDFThe purpose of this study was obtained method of controlling diseases caused by Aeromonas hydrophila in fish farming is environmentally friendly. In this study the sensitivity of the test A. hydrophila, a minimum test konsentari inhibiting A.hydrophila (MIC test) and toxicity test on tilapia. The design used for toxicity tests iscompletely randomized design with 4 treatments it A = Fish injected with extracts bangkal concentration of 20 %, B = Fish injected with extracts bangkal concentration of 40 %, C = Fish injected with extracts of 80 % concentration bangkal, and D =Control ( fish not injected ), repeated 3 times. This treatment was obtained from theresults of the sensitivity test antibacterial bangkal inhibition and has the power to killmost of the bacteria against A. hydrophila is bangkal leaf extract with distilled watersolvent. MIC testing showed that the extract bangkal - distilled water has a minimum of 20 % inhibition of the bacterial activity A. hydrophila. Results of toxicity tests conducted on tilapia with a concentration of 20 %, 40 % and 80 % mortality of tilapia under 50 %. Haematological observation that eretrosit, leokosit, blood plasm, hematocrit and leokokrit in each treatment is still in the normal range. The water quality parameters, dissolved oxygen, pH, ammonia, CO2 and temperature can still support the normal life of tilapia

Get PDFThe study is intended as an attempt domestication through climbing perch spawning in the container cultivation. The research was conducted at the Laboratory of Wetlands Program University Faculty of Fisheries Aquaculture Lambung Mangkurat.Three main points in support of the spawning success of fish, namely: gonadaldevelopment, ovulation and spawning. Naturally development climbing perch fishgonads occurred in the early dry season to peak season and at the beginning of the rainy season or during the rainy season, spawning occurred. This natural state is trying to be adopted in the cultivation of container, with fashting for 1, 2 and 3 days with water levels, 10, 15 and 20 cm. The result is a latent time of 11.7 hours to 39 hours, fecundity between 5310 to 7376 grains, egg diameter 0.5 to 0.8 mm, the degree of fertilization between 88.2 to 93.2 percent and the degree of hatching between 87, 0 to 91.6 percent
KINERJA REPRODUKSI DENGAN INDUKSI OODEV DALAM VITELOGNESIS PADA REMATURASI INDUK IKAN PATIN (Pangasius hypophthalmus) DI DALAM WADAH BUDIDAYA
Get PDFThe objective of this research was to study the effect of Oodev as know as PMSGad gonad rematurity in infertile broodstock of P. hypophthalmus by Oodev Hormoneinjection. The treatments consisted of control 0 ml Oodev/kg fish weight (D), 0,3 mlOodev/kg fish weight (A). 0,5 ml Oodev/kg fish weight (B) and 0,ml Oodev/kg fishweight (C). with four replications of each. Fish weight at the beginning of experiment was 5 to 7 kg/individual. The result showed that Oodev had positive effect on eggmaturation. This was shown by the value of average of eggs diameter. The maximumsize of egg diameter for fish with hormone injection were larger than without injection. The best treatment was 0,5 ml Oodev/kg fish weight(B) and the largest than those of group C and A. It was concluded that injection of Oodev (PMSGad) is effective in promoting gonad maturation and oocyte development in the catfish

Get PDFThe aim of this experiment was to evaluate the nutrient quality of leucaena leaf meal(LLM) with addition of sheep rumen liquor enzyme for nile tilapia feed which incubated 24 hours (in vitro); This experiment was designed in completely randomized design with 6 treatments and 3 replications each with different level of enzyme addition (0; 20; 40;60; 80; and 100 ml/kg LLM). Results of the experiment showed that nutrient quality of LLM with addition of sheep rumen liquor enzyme which incubated for 24 hours, wheresignificantly affected (P<0.05) on decrease of crude fiber (53,640%), NDF, ADFcomponent and phytic acid (68,088%). Over all conclusion is a great potential for using sheep rumen liquor enzyme for improving nutrition quality of leucaena leaf meal
LAND SUITABILITY ANALYSIS OF WHITE SHRIMP (LITOPENAEUSVANNAMEI) AQUACULTURE IN THE COASTAL AREA OF BARRU DISTRICT SOUTH SULAWESI – INDONESIA
Get PDFThe coastal area of Barru District has a wide brackishwater pond, but its productivity is relatively low. A research to determine land suitability as one of the brackish water pond productivity-raising projects is needed. Considerable factors in determining land suitability for white shrimp aquaculture covers topography and hydrology, soil conditions, water quality, and climate. Quality of water is observed during a rainy and dry season. Spatial analysis using Geographic Information System is applied in the determination of land suitability for shrimp aquaculture. The analysis shows the actual land suitability of the existing ponds in Barru district, namely 2.399 ha, where land is classified as highly suitable (S1 class), 232.94 ha (9.71%) classified as moderately suitable (S2 class), 1,444.20 ha (60.20%) classified as marginally suitable (S3 class), 721.14 (30.06%) and classified as marginally low suitable (N class), 0.72 ha (0.03%), Limiting factors during the rainy season are the flood, while salinity is the main limiting factor during a dry season. Generally, other limiting factors are of the water sources, low level of pH soil and roughness of soil texture in a certain area
