Oxygen consumption (OC) is one of important factors in aquaculture activities, as the oxygen is a vital condition for all the organisms living in the water and having an aerobic type of respiration. OC is the preferred method for measuring and reporting the metabolic rate in fish. The aims of this study were to evaluate the effects of salinity on OC and blood properties of grey mullets. Five experimental groups were conducted to measure OC and blood properties of grey mullets Mugil cephalus (BW: 187.9 ± 45.8 g) according to salinity (30→0 psu, 0→30 psu) changes; SDS: fish reared in seawater (SW, 30 psu) directly shifted to SW, SGF: SW fish gradually shifted to freshwater (FW, 0 psu), SDF: SW fish directly shifted to FW, FDF: FW fish directly shifted to FW, and FDS: FW fish directly shifted to SW. The result showed that OC tended to decrease in the groups of SW fish shifted to FW showing 194.5 mg O2/kg/h at 25°C in SDS to 82.4 mg O2/kg/h at 15°C in SGF. On the contrary, OC increased in the groups of FW fish shifted to SW showing 80.5 mg O2/kg/h at 15°C in FDF to 184.0 mg O2/kg/h at 25°C in FDS. Cortisol levels at the end of experiments were rapidly increased with the lowering salinities in SW fish shifted to FW showing 20.6 ng/mL in SDS to 316.2 ng/mL in SDF, while those were decreased with the increasing salinities in FW fish shifted to SW showing 40.2 ng/mL in FDF to 10.3 ng/mL in FDS. However, glucose levels showed no significant differences among all experimental groups. Based on the information from this study, aquaculture of grey mullet might be applied or developed in freshwater due to its osmotic adaptation ability.

Sponge global demand for industry and research needs far exceeds supply from the sea. Aquaculture is considered as the only viable method that can supply sufficient and sustainable quantities of sponges. Aquaculture method is also one of efforts to anticipate and avoid the over-harvesting of sponges in nature. However, culture methods need to be determined to provide the platform for commercial success. In this study sponges (Callyspongia sp., Callyspongia basilana, and Haliclona sp.) were successfully cultured by transplantation method using polyethylene net with the initial explant sizes of 1 cm, 3 cm, and 5 cm. The result showed that the sponge growth and survival rates were dependent on the species. Callyspongia sp. and Callyspongia basilana gave the highest growth and survival rates on the treatment 3 cm with the final explants length reached 12.20 ± 2.35 cm and 7.603 ± 0.93 cm and survival rates reached 98.33% and 36.67%. In contrast, Haliclona sp. had the highest growth (21.67 ± 0.25) and survival (95%) on treatment 5 cm. Nevertheless, among the three species, treatment using 3 cm and 5 cm of initial explant sizes did not show a significant difference. Therefore for the efficiency of explants use, the best initial explant length for culturing the three species of sponges is 3 cm.

Mangrove litters as a source of nutrients for sylvofishery pond (TS), sedimented pond (TT), and conservation pond (TP) was studied at Blanakan mangrove pond during April until June 2008. The variables of study were litter production, litter decomposition, and dissolved nutrients (ammonium, nitrite, nitrate, and phosphate). The obtained data were analyzed using F test and continued using Least Significant Different (LSD). The results showed that litter production at TS, TT, and TP were 19.55±4.34 ton/ha/year, 15.90±1.98 ton/ha/year, and 21.67±1.89 ton/ha/year respectively. The decomposition rate at TS, TT, and TP was 0.051±0.038, 0.051±0.018, and 0.081±0.041, respectively. Mangrove litters were potentially as a source of dissolved nutrients at Blanakan mangrove pond. Increasing both litter production and decomposition rate could increase ammonium, nitrite, and phosphate. Therefore, mangrove litters were play role for determined the fertility at Blanakan mangrove pond.

Tilapias are indigeneous species to Africa, but interest in their aquaculture potential has led to nearly worldwide distribution of the species within the past fifty years. The most popular species of tilapias cultured in the world is Oreochromis niloticus. Red tilapia, one of tilapia varieties, is a highly valued commodity in global market. Based on this reason, red tilapia culture should be developed to supply the market demand. Tilapias can be culturred in brackishwater ponds due to its tolerant ability to saline water. This study was carried out to know the potential of tilapia especially the NIFI red tilapia cultured in saline water. The seeds of NIFI red tilapia were reared in three levels of salinity, i.e. 10, 20, and 30 ppt with 0 ppt as the control population. The experiment was conducted in wet laboratory for 56 days. The results showed that the difference of salinity level did not affect the performance of NIFI red tilapia, including specific growth rate, survival rate, total biomass, and food conversion ratios. Based on these results, it is suggested that NIFI red tilapia can be cultured in saline waters.

Infection of grouper sleepy disease iridovirus (GSDIV) which is a member of Megalocytivirus causes mass mortalities in marine fish in Indonesia. This study was conducted to know the effectiveness of recombinant subunit vaccine of GSDIV with an addition of adjuvants against GSDIV infection. Inactive bacteria Eschericia coli containing recombinant MCP-GSDIV protein was added with montanide ISA adjuvant at a ratio of 3:7. The vaccine was administered to humpback grouper, Cromileptes altivelis by intramuscular and intraperitoneal injection at a dose of 0.1 mL/fish. Test of the vaccine in humpback grouper was performed in four replicates (four trials). Results of the vaccination showed that the recombinant protein vaccine added with the adjuvant increased immunity of humpback grouper, indicated by higher relative percent survival (RPS= 77.78%) compared to negative control (PBS) and 50% higher compared to protein control (pET Sumo CAT) at two weeks post vaccination. The RPS values of the recombinant protein vaccine were still higher (53.57%-72.73%) than those of the control vaccine and 25%-53.33% of the protein control in the 4th week post vaccination. GSDIV detection by PCR showed that MCP-GSDIV-DNA and pET Sumo CAT-DNA were not detected in the vaccinated fish after one, two, three, and four weeks post vaccination. The fish died in both of vaccinated and control groups after experimental challenge with GSDIV were found to be infected with GSDIV. It can be stated that recombinant subunit vaccine of GSDIV with the addition of montanide ISA adjuvant could be used to prevent and diminish mortalities of grouper against GSDIV infection.

Spatial distribution of brackishwater pond soil has important role in the system of bioenvironment including brackishwater pond environment. This research was aimed to determine the spatial distribution of some chemical characteristics of an acid sulfate soil-affected brackishwater pond in coastal area of Luwu Regency South Sulawesi Province, Indonesia. ALOS AVNIR-2 images (acquisition 16 May 2008, 16 October 2008, 17 September 2009) were integrated with Indonesian Topographic maps to obtain base map. Sampling soil points were determined by simple random sampling in 104 points for two different soil depths i.e. 0-0.2 m and 0.5-0.7 m. A total of 18 soil chemical characteristics was measured in the field and analyzed in the laboratory. Geostatistic using kriging method in the ArcGIS 9.3 software was used to interpolate the data. The results of this study indicated that in general pond soil chemical characteristics in Luwu Regency could be categorized with high variability or relatively heterogenic wi th the value of var iation coefficient more than 36%. The soil characteristics that explain acidity had shown similar pattern in spatial distribution as well as other soil characteristics with soil nutrient. The high value of pH and low value of PO4 were generally found in the northern part of Luwu Regency, including East Lamasi, East Walenrang, Bua, and Ponrang Subdistricts. It is recommended that soil management in brackishwater ponds of Luwu Regency could be based on soil chemical characteristics so its could improve the production through minimizing the input, increasing carrying capacity, and avoiding environmental degradation.

The apparent digestibility (AD) of eight feed ingredients are widely available in Indonesia was determined. In each of two 5x5 latin-square experimental, tiger grouper Epinephelus fuscoguttatus juveniles (100—150 g) were fed a reference diet and four test diets in accordance with the latin-square design. Test feed ingredients were substituted at rates of 40% for animal meals or 30% for plant meals. Chromic oxide was used as the digestibility marker. In determining the ingredient AD, the substitution ratio was calculated as the proportion of the nutrient (or energy) contributed by the test ingredient on an ‘as-is’ basis. Digestibility tanks were steeply slope 200 L cylindroconical tanks with a bottom outlet to facilitate faecal collection, which was carried out at 3-hourly intervals throughout the day. Each collection period took 5—7 days with a similar acclimatization time between diets. A combined ANOVA of the data for both experimental showed no difference (P>0.05) in the AD’s for each reference diets. Thus for comparative purpose, the derived AD’s of the test ingredients were analysed as a single ANOVA. The digestibility of animal meals was generally high(>59% for dry matter, >83% for protein, >65% for lipid, and >70 for gross energy) while that of plant meals was slow (<53% for dry matter, <53% for protein, <66% for lipid, and <46% for gross energy). This information will enable grow-out feeds for tiger grouper to be formulated on a least-cost digestible nutrient basis.

White spot syndrome virus (WSSV) has become epidemic in Indonesia and affecting shrimp aquaculture interm of its production. White spot syndrome virus is transmitted from one to other ponds, through crustacean, included planktonic copepode as carrier for WSSV and through water from affected shrimp pond. A cluster model, consist of shrimp grow out ponds surrounded by non-shrimp pond as a role of biosecurity has been developed. The model aimed to prevent white spot virus transmission in extensive giant tiger shrimp pond. The study was conducted in two sites at Demak District, Central Java Province. As the treatment, a cluster consist of three shrimp ponds in site I, and two shrimp ponds in site II, each was surrounded by buffer ponds rearing only finfish. As the control, five extensive shrimp grow out ponds in site I and three shrimp grow out ponds in site II, with shrimp pond has neither applied biosecurity nor surrounded by non-shrimp pond as biosecurity as well considered as control ponds. The results found that treatment of cluster shrimp ponds surrounded by non-shrimp ponds could hold shrimp at duration of culture in the grow out pond (DOC) 105.6±4.5 days significantly much longer than that of control that harvested at 60.9±16.0 days due to WSSV outbreak. Survival rate in trial ponds was 77.6±3.6%, significantly higher than that of control at 22.6±15.8%. Shrimp production in treatment ponds has total production of 425.1±146.6 kg/ha significantly higher than that of control that could only produced 54.5±47.6 kg/ha. Implementation of Better Management Practices (BMP) by arranging shrimp ponds in cluster and surrounding by non-shrimp ponds proven effectively prevent WSSV transmission from traditional shrimp ponds in surrounding area.

The stable mass seed production technique of marble goby, Oxyeleotris marmoratus has not yet been established due to high mortality occurring on the early juvenile stage and/or after 40 days after hatching (d AH). In order to establish the mass seed production technique, O. marmoratus juveniles of 40 d AH were reared for 60 days to determine growth, survival and digestive enzyme activity at different types of feed (trash fish, artificial feed and Artemia sp. nauplii). Specific growth rate (5.32) and survival rate (91.3%) in juveniles fed Artemia sp. nauplii showed significantly higher (P<0.05) than those of juveniles fed trash fish and artificial feed. At the end of the experiment, the mean specific trypsin, amylase and lipase activities of juveniles fed Artemia sp. nauplii were recorded as 0.04 mU mg protein-1m-1, 0.114 mg maltose mg protein-1h-1 and 9.58 m Units, respectively, and they were significantly higher than those of juveniles fed trash fish and artificial feed. In the present study it was shown that O. marmoratus early juveniles had more efficient digestibility and absorption the nutrient when fed with Artemia.
