In-shore marine environment and its adjoining estuary has a potential susceptibility to water pollution due to the continuous discharge of its unhealthy catchment. Seawater quality studies commonly require a very detailed water sampling and analysis, leading to high expenditures on time and energy. This study aims to examine the water quality of the Dodokan Estuary using remote sensing and geographic information system (GIS) approaches, and to determine the most appropriate water environment mapping unit for marine environment suitability studies. Landsat 8 and QuickBird® were used to extract water quality parameters using related spectral transformations. Field surveys were conducted concurrently to the Landsat 8 acquisition time on the study area, to collect water samples for laboratory analysis including sea surface temperature (SST), chlorophyll-a, Dissolved Oxygen (DO), and Total Suspended Solid (TSS). Mapping units were generated based on visual interpretation on QuickBird® for estuarine plumes, to identify the possible distribution of suspended material from its catchment. The statistical analyses present that the parameter extracted from the satellite imagery and from laboratory analysis produces R values of 0.7 in average, despite its low value on chlorophyll-a. By utilizing assorted sea-water marine suitability criteria, it can be concluded that the inshore marine environment in the Dodokan Estuary and its surrounding area are suitable for various biota conservation e.g. coral, sea-grass, and mangrove, and in contrast, marine aquaculture. The knowledgeable uses of remote sensing and GIS also assist the sea-water qualities assessment mapping in term of providing boarder understanding of a water environment condition to effectively minimize the cost of sampling.

Carotenoid is one of nutrition factors which can improve red color pigmentation. The purpose of this study was to investigate the best type of carotene which can increase red pigment performance and to evaluate how long the effect should be retaining in order to maintain red color performance on leopard grouper seeds. This study consisted of 2 experiments; those were the effect of various kinds of carotene materials in feed addition and the effect of the termination of the addition of carotene materials in the feed toward red color performance on leopard grouper seed. The treatments given to the first experiment were the provision of various kinds of carotene materials which were type of A. Haematococcus pluvialis, B. Phaffiarhodozyma, C. Astax Oil, D. Control (without carotene materials) and the treatments to the second experiment are A. Leopard grouper seed – phaffia was still given additional Phaffia rodhozyma, B. Leopard grouper seed – haematococcus was still given additional Haematococcus pluvialis, C. leopard grouper seed (from larvae - phaffia / haematococcus) was terminated from carotene materials addition. The first experiment was applied from larva up to D60 seed and for the second experiment was the follow-up response from the first experiment conducted on D60 seed up to D150. Based on the study result, it indicates that carotene materials of Haematococcus pluvialis type gave the best color performance improvement (P value 4.71 x 10-7 < 0.05). The provision of carotene materials intake decreases color performance both visually and total contain of carotene (P value 5.97 x 10-5< 0.05) (Tabel 1). Carotenenoids should be continuously given as trigger to maintain red color performance on leopard grouper seed. There was protein band in the range of 82.1 – 84.2 kDa which was assumed as protein expression of astaxanthin

Samples were consisted of three categories : 1,000 m2 per pond for 16 farmers: 1,000-1,500 m2 per ponds for 14 farmers and >1,500 – 2,500 m2 per pond for 11 farmers. The results showed that the white shrimp culture in Bantul District coastal sandy soil area was an intensive system with average pond width 1,300 m2. Average pond category < 1,000 m2 was 636 m2; average pond category 1,000-1,500 m2 was 1,357 m2 and average pond category >1,500 – 2,500 m2 was 2.191 m2. Generally the fixed costs incurred IDR 24,876,128,- per pond/cycle and variable costs IDR 72,839,121 per pond/cycle (IDR 218,517,362,- per pond/year). The revenue of the culture was IDR 109,709,805,- per pond/year, with the ratio value between the total revenue with total costs [Revenue (R) / Cost (C) ratio ] was 1.37. The Break Event Point (BEP) of shrimp products was 4,909 kg and the Break Event Point (BEP) of shrimp price was IDR 34,312,-. The highest productivity of shrimp was 19.7 Ton/ha/cycle, which be cultured in the 1,000-1,500 m2 ponds, with incomed IDR 169,507,143 per pond/cycle and the Revenue/Cost ratio (R/C ratio) was 1.60. The BEP of shrimp products was 5,069 Kg and the BEP of shrimp price was IDR 28,187,-

Lobster, one of the high values sea-cage culture commodities in Indonesia, has some specific requirements of life environment. However, there haven’t been any studies that specifically identify these potential sites. Until today it is only 3.50 ha out of 526.86 Ha of these that have been utilized. This study aims to map the marine suitability environment for lobster cultivation in Ekas Bay, using remote sensing and GIS approaches. The requirement parameters maps for lobster marine suitability, includes oxygen levels (DO), nutrition, salinity, temperature, depthness, pH, and water clearence which are able to be extracted from Landsat 8 imagery. Using GIS, a model was developed to integrate those maps with marine environment secondary maps, water laboratory analysis, and other information from interview result with the local farmer’s. The result shows that lobsters live in the environment which has the temperature between 200 to 250C and at the water depth of reaching 100 m. Laboratory analysis result presents the pH value of above 7 in average, DO ranges from 5-8 ppm, and salinity level from 28 to 35 ppt. In summary, the integration of remote sensing and GIS approaches are able to identify the common parameter that support the environment suitability for lobsters which is then formulated as a standard of marine environment suitability mapping.

Asian seabass (Lates calcarifer) aquaculture is potential developing industry in Australia and Indonesia. As the aquaculture industry intensifies, the occurrence of significant diseases becomes more likely. Hence, it is important to find better methods for controlling diseases in this industry. Research on mammals and fish have previously demonstrated the potential benefits of dietary nucleotides to enhance immune function of the animal to combat diseases. However there is still very limited study of this subject in Asian seabass. This study aims to investigate the role of dietary nucleotides on the growth and immune responses of Asian seabass. Juvenile Asian seabass with average weight of 13.8±1.29 (mean ± SD) g were fed three different diets containing either Optimun® nucleotides or a mix of pure nucleotides at 0.25% per kg feed and one basal diet (nucleotide free diet). Fish were fed at 3 % BW per day for 28 days. Results showed that dietary nucleotides did not significantly effect the growth, survival rate, and immune responses of the fish. However Optimun® diet gave higher result in terms of growth, leucocrit level, lysozyme activity and respiratory burst activity of head kidney leucocyte compare to basal and the mix of pure nucleotide diets.

Organic liquid fertilizer is the source of nutrients. This fertilizer can be used to improve the water quality. It is enviromentally friendly and relatively cheap. Application of the fertilizer has been done on aquaculture. At the tidal lowland areas, application of this fertilizer is mostly as soil improvement agent. It is limited to be used as water quality improvement agent. Tidal lowland has an acid soil with a low fertility level characters. The objectives of the study are to know the effect of liquid organic fertilizer to the water quality (temperature, pH, dissolved oxigen, ammonia) and to the amount of plankton in the ponds. This research was done at the reclaimed tidal lowland in Banyuasin District of South Sumatera, Indonesia. The organic liquid fertilizer was made by fermentation of both animals manures and vegetable waste with the percentage of N : P2O5 : K2O were 0.120 : 0.023 : 0.750. Water quality data was taken three times in every three days (plankton) from the ponds that was added by liquid fertilizer with dose of 4.35 L /pond (P1) and 8.7 L/pond (P2). All the water quality data were analyzed qualitatively. The results show that on treated ponds pH dropped slightly since the beginning with pH 6.0 and remain 6.4 - 6.8 in the last day. The value of Ammonia ranges 0.06-0.15 mg.L-1 and Dissolve oxigen range 1.9-2.5 mg.L-1‑. Phytoplankton and zooplankton amount increased and reached the peak on day 12 (12033 ind.L-1 and 364 ind.L-1 respectively), and finally turned down slowly. Therefore, liquid fertilizer addition should be given to the ponds more than once during fish rearing period. It is in order to increase the amount of plankton and to manage the water quality in the reclaimed tidal lowlands ponds
