The information about the optimum and tolerable salinity to support in the success of coral trout grouper’s seed culture is still limited until now. The aim of this study was to understand the effect of different salinity on growth, survival, feed conversion (FCR) and the profile of blood (hematocrit and hemoglobin) of coral trout grouper seed. The seed with total length 6.0 ± 0.5 cm and body weight 3.2±0.3 g were used as tested animals. Five different salinity treatments, namely: 10±1 ppt (A), 16±1 ppt (B), 22±1 ppt (C), 28±1 ppt (D), and the sea water (34 ppt) as a control (E) were undertaken in this study, with three replications for each treatment. Salinity values were reach by adding freshwater into the tested seawater. Water changing system in this study was performed in recirculation process, with 25% of water replacement every 7 days. The result of this study showed that the survival rate values were 100% for all treatments, indicating that coral trout grouper seed can be cultured in the range of salinity between 10 to 34 ppt. The highest total length and body weight were recorded from treatment C (22 ppt), as well as noted to gain the lowest FCR. Correspondingly, the seed in treatment C also founded to have in the greatest amount of hematocrit and hemoglobin. Optimum salinity for rearing of coral trout grouper seeds with total length 6 cm was 22 ppt. Keywords: salinity, growth, survival rate, feed conversion, blood profile

The problems in culture of early juvenile phase of spiny lobster Panulirus homarus is low survival rate of the seed. One of strategies to improve production is using filtration system during nursery of spiny lobster. The aim of this study to evaluate differentation of physical filtration system on responsse stress and survival rate of juvenile P. homarus. Experimental design of this study consisted of four treatments and two replications. The treatments were using flow through system without protein skimmer and filter (K), filtration system with protein skimmer (SK), filtration system with top filter (F) and filtration system with combinations of protein skimmer and top filter (SKF). P. homarus with initial weight 0.18+0.01 g were cultured for 60 days with density 250 lobster/tank. During maintenance, P. homarus were fed trash fish with feeding rate 20% of body weight. Parameters of glucose hemolymph were evaluated to determine stress response. Stress response was determined at day 0, 6, 20 and 60. Parameters of survival rate were determined at the end of experiment. The result showed that the treatment of filtration system with combination of protein skimmer and top filter (SKF) decreased stress responsse by decreasing glucose hemolymph of juvenile P. homarus during maintenance. Survival rate also higher (P<0.05) in treatment SKF (33.2%) than other treatments. It is concluded that SKF was the best physical filtration system for juvenile period of spiny lobster P. homarus Keywords: filtration system, glucose hemolymph, spiny lobster, survival rate

One of the problems that often occured in the bay area is a sedimentation process that occurred continuously, causing silting. The movement of sediment material in the process of sedimentation is influenced by the movement of the water flow like the tides, winds, currents and waves. The aim of this study was to determine the characteristics of the hydrodynamic conditions, particularly the distribution pattern and the capacity of the sediments in the Kendari Bay with oceanographic modeling approach. Bathymetry data measured at the site of the research conducted in August 2015. The analysis of distribution patterns of sedimentation, sedimentation capacity, wave hindcasting, wind data and tidal data using software, hindcasting results indicate the dominant wind direction coming from the east. Type tides in Kendari Bay is a mixed mainly semiurdunal tides. The concentration of suspended sediment at low tide is greater than at high tide. Keywords: sediment transport, wave characteristics, Kendari Bay, hydro - dynamics, mike21

High market demand for tuna drives the increasing intensity of tuna fishery in Sendangbiru waters. This occours also in almost all of Indonesian waters. High intensity of tuna fishing especially in Southern Java will threaten the preservation and sustainabilityof tuna resource. The decreasing trend of CPUE occured in the last 3 years (2013-2015) indicates that the exploitation rate of tuna resources in Sendangbiru was over fishing. This study aims to assess the status of tuna reasources due to fishing in Sendangbiru. The method used in this research is length based spawning potential ratio approaches or LB-SPR. Results from this study showed that the utilization of tuna resources in Sendangbiru is already at the level of over-exploited as shown by SPR value of 16.98 (less than 20%). Keywords : decreasing tren of CPUE, LB-SPR, Tuna fisheries

Madura strait receives waste disposal from various activites in the mainland, making it vulnerable to contamination of harmful pollutants. Some of the harmful pollutants are heavy metal Pb and Cd. The high concentration Cd and Pb give negative impacts to the biota including bivalves. This study was conducted to assess the distribution of heavy metals Pb and Cd in the waters and their accumulation in bivalves Anadara nodifera, Meretrix lyrata, and Solen lamarckii in coastal waters of the West Madura Strait. Heavy metal analysis refer to APHA 2012 using AAS. The results showed that concentration of Cd and Pb in water were below the quality standards, while in sediment were above the standard (Cd of 7.20 mg/kg and Pb of 62.06 mg/kg). The concentration of Cd in bivalve were different among the species tested A. nodifera of 6.10 mg/kg, M. lyrata of 3.65 mg/kg, and S. lamarckii of 2.74 mg/kg, as well as Pb concentration A. nodifera of 60.10 mg/kg, M. lyrata of 51.48 mg/kg, and S. lamarckii of 45.29 mg/kg). These results indicated that the three shells have exceeded the maximum limit of heavy metal contamination in food (Cd of 1.0 mg/kg and Pb of 1.5 mg/kg). Keywords: bivalve, heavy metal, Madura Strait

Oil spills at sea are common in the shipping lanes of the ship as well as the locations of offshore oil drilling. Unfortunately, in every occurrence of the oil spill, we only see the effects after the occurrence, without knowing the original source. Indonesian Numerical Coastal Environmental Assessment (IndoNACE) is research collaboration between Indonesian and Germany by applying satellite data, numerical modeling, and field observations to make an assessment on environmental consequences to oil spills at sea. One of the locations of these research activities is Pari Island, Seribu Islands, North Jakarta. Simulation of hydrodynamic models around Pulau Pari with Hamburg Shelf Ocean Model (HAMSOM) was performed using tides, surface winds, and density difference of seawater as input. Afterwards, by utilizing results of the hydrodynamic model, the spreading of oil spills as well as the origin of the oil spills were estimated using forward and backward trajectory models, respectively. In the case study of Pari Island, there is a presence of thin film of oil in 5 November 2015 that disappears after one day. We suggest that the origin of oil spills were found on the beach Pari Island is expected from the east - northeast of Thousand Islands and is likely from the subsea pipeline which runs from the north to the city of Jakarta or shipping lanes through the Indonesian archipelagic sea lanes (ALKI) I of Karimata Strait up to Java Sea and the Jakarta Bay.
