As a filter feeder, windowpane oyster, Placuna placenta, which lives as a sedentary animal is very appropriate to be used as an eco-sentinel organism in marine bio-monitoring campaign. The study of lead (Pb) content in the tissue and shell of P. placenta was conducted in coastal waters of Mandalle, Pangkajene Kepulauan District, South Sulawesi. A hundred of oysters were collected from coastal waters of Mandalle. Morphometry parameters which were length, high, width, and dry weight of tissue were measured in the laboratory. Those parameters were used for determination of Condition Index (CI). Metal was analyzed by Atomic Absorption Spectrometry. The results showed that the contents of Pb in tissue and shell were 0.021 and 0.014 mg/kg DW (dry weight) respectively. The concentration of Pb in tissue was not overreach by BPOM 2009 Number Hk.00.06.1.52.4011 of 1.5 mg / kg DW (dry weight). After calculating Maximum Tolerable Intake (MTI), we found that MTI was 7.79 kg/day. In terms of marine monitoring campaign, we can theoretically use the CI as a morphological biomarker. After calculating the relationship between Pb in tissue and shell, we found that the value of CI was not correlated significantly with Pb content in tissue and shell. However, the correlation coefficient between Pb in tissue and CI was stronger than that in the shell. The potential of CI of windowpane oyster as a morphological biomarker was discussed.Keywords: Placuna placenta, lead, MTI, morphological biomarker

Saline tilapia fish is a result of technology engineering technique that is tolerant with brackish waters and sea with salinity ≥ 20 ppt. The main problem in the development of saline tilapia is the availability of seeds because the resulting synthesis is still low. One effort to overcome the problem of low tilapia salinity this is by providing dissolved organic material such as glucose. Glucose plays an important role as a source of energy for animals including tilapia. The aim of this research is to determine the optimum dose of dissolved glucose to the survival and growth of salt tilapia larvae (Oreochromis niloticus). The research was conducted from March to May 2017 at Brackish Water Aquaculture (BPBAP) Takalar, South Sulawesi. The research container using 25 L plastic volume basin amounted to 15 pieces. The test animals used were 7-day saline tilapia larvae of 0.03 gram sized for 20 days. The glucose used is pure glucose in powder form. The study was designed using a complete randomized design consisting of 5 treatments and each having 3 replications. The five treatments are 0, 50, 100, 150, 200 ppm per day added to the once-daily research container that is the morning. The result of variance analysis showed that soluble glucose administration had significant effect (p <0.01) on the synthesis and growth rate of saline tilapia fish. The highest survival rates and growth rates were achieved at 100 ppm doses of 94.44% and 14.93% / day respectively, while the lowest at doses of 0 ppm were 74.81% and 11.85% / day respectively.Keywords: glucose, salin tilapia, survival, growth rate

This study attempted to analyze the distribution and contamination status of heavy metals (Cu, Fe and Zn) along western coast of Bali Strait in Banyuwangi, East Java. Bali Strait is one of the many straits in Indonesia with high fisheries activities that could potentially contributed to high heavy metal pollution. There were five sampling areas from the north to south: Pantai Watu Dodol, Pantai Kalipuro, Ketapang Port, Pantai Boom and Muncar as the fish landing area. Heavy metal pollution in these locations comes from many different activities such as tourism, fish capture and fish industry and also domestic activities. Contamination factor (CF), geo-accumulation index (Igeo) and enrichment factor (EF) of each heavy metal were calculated to obtain contamination status of the research area. The concentrations of Fe were observed the highest (1.5-129.9 mg/kg) followed by Zn (13.2-23.5 mg/kg) and Cu (2.2-7.8 mg/kg). The distribution of Cu, Fe and Zn showed variability among the sampling locations in which high concentrations of Cu and Zn were higher in Ketapang Port, whereas high concentration of Fe was high in almost all sampling locations. According to the pollution index, contamination factors of Cu, Fe and Zn were low (CF < 1 and Igeo < 1). However, high index of EF (> 50) showed high influence of the anthropogenic activities to the contribution of the metals to the environment. This could also because of the high background value used in the calculation of the index due to the difficulties in finding background value from the sampling areas.Keywords: heavy metals, pollution index, contamination factor, geo-accumulation index, Bali Strait

In the rearing of fish larvae, artificial feed can be given when digestive enzymes have been produced. To improve the ability of fish larvae to utilize artificial feeds can be done with the addition of exogenous enzyme into the artificial feeds. The aim of this study was to determine the dose of papain enzyme and the correct predigest artificial feeding stadium on metamorphosis rate and glycogen content of mangrove larvae (Scylla olivacea). The experimental design used was a factorial pattern with a complete randomized baseline design, the first factor being the dose of papain enzyme (0%, 1.5%, 3.0% and 4.5%), while the second factor was the predigest artificial feeding stage (zoea 2 and 3). The results showed that the difference of dose of papain enzyme and predigest artificial feeding stages had significant effect (p <0.05) on the metamorphosis rate of 7, 9, 10, 12, 13, 16 and 17 day larvae, but the interaction between them was not significant (p>0,05). The rate of metamorphosis at doses of enzyme papain was 0% and 1.5% longer and significantly different (p <0.05) compared to 3% and 4.5% doses. The rate of metamorphosis at doses of 3.0% and 4.5% was not significantly different (p> 0.05). The content of glycogen larvae in dose of enzyme papain 4,5% not different than dose 1,5% and 3,0% but higher and significantly different than dose 0%. Glycogen content at dose 0%, 1,5% and 3,0%. was not significantly different (p> 0.05).

Hatchery managers and maintaining genetic diversity and fitness population in endangered and threatened species in pond is a important and difficult thing to do. But is must to do for conservation biology. Fitness and structure population depends on effective breeding number (Ne) and population connectivity between each other. The second most important thing is gene flow and genetic drift. Ne is major role in the maintenance of genetic diversity as indicator for inbreeding depresion and genetic drift. We sampled 6 hatchery in Jakarta and Bekasi Indonesia region and used 12 polymorphic microsatellite loci to quantify population genetic structure. Result in this study are, each farm have different methode. The old farmers is bapak Gusi and bapak Hasan (+30 years). Ne in bapak Hasan and bapak Gusi hatchery is 66,667 and F value is 0,00749 and loosing allele (P) is 0,26183. Compared with younger farmers bapak Yahya (5 years) have Ne = 133,333, F = 0,00375 and P = 0,06855. Even though hatchery bapak Hasan and bapak Gusi have the same value Ne, F and P but the result in population structure they are different founder populations. Hatchery bapak Hasan have unique structure and alleles composition compared with other hatchery.Keywords: breeding, management, Melanotaenia boesemani, hatchery, population.

The existence of mangrove in coast areas have both ecologic and physical important functions. Mangrove is a high productive ecosystem. Litters from fallen leaves and twigs are organic sources for macrozoobenthic life. The aim of this research was to determine the response of macrozoobenthics on total organic matter content and other chemical-physico characters of sediments due to differences in mangrove conditions. This research was conducted from May to September 2016 in Sub-district of Ampallas, Distric of Mamuju, Province of West Sulawesi, Indonesia. Sediments in 20 cm2 transects were collected using small shovel to obtain the macrozoobenthic samples. The sediments contained macrozoobenthics were sieved using a 1 mm mesh size sieve net. Four sampling sites were chosen, each to represent areas with no mangroves, low, medium, and high densities. The total of organic matter samples were collected using 2 inch diameter of PVC pipe cores, which were analyzed further using Loss by Ignition method. Besides total of organic matter, several parameters (i.e. redox potential, sediment pH, salinity, temperature, and dissolved oxygen) were measured. The results showed that gastropods dominated the existed macrozoobenthics. Gastropods and oligochaete lived in greater amounts in high mangrove density site with higher organic matter content and fine substrate.Keywords: mangroves, macrozoobenthics, organic matter, Distric of Mamuju
