The Tripa Peat Swamp forest is located in Nagan Raya and Aceh Barat Daya districts. The forest has been deforested and converted to agricultural lands. Hence, the objective of the present study was to evaluate the community structure of macrozoobenthos in Tripa peat swamp. Five sampling locations were determinated using purposive random sampling which was focussed in the main river mouths of Tripa, Suak Tripa, Seuneam, Batee and Taduu Rivers. The sediment was collected in three plots (1m x 1m) at every sampling location. The results showed that, there were 34 species of macrozoobenthos recorded during the sampling, it is belonging to 4 classes; Gastropoda, Bivalvia, Crustacea and Insecta. The species richness were ranged between 1.12 to 1.58, indicates low category. The diversity and evenness indices were ranged between 0.62 to 2.44 and 0.19 to 0.73, respectively; indicates low to moderate values. It was concluded that the macrozoobenthos community of Rawa Tripa was in unstabile condition. Rawa Gambut Tripa terletak di Kabupaten Nagan Raya dan Aceh Barat Daya Provinsi Aceh. Penelitian ini bertujuan untuk mengetahui komunitas makrozoobentos di kawasan Rawa Gambut Tripa. Penelitian dilakukan pada bulan Juni dan Juli 2013. Penentuan area dan titik sampling menggunakan metode purposive random sampling berdasarkan pertimbangan topografi kondisi lingkungan, yaitu pada 4 muara sungai utama di kawasan ini. Sampel sedimen diambil menggunakan skop dengan plot (1m x 1m) sebanyak 3 plot pada setiap stasiun, kemudian disaring dan disortir menggunakan tangan (hand sorting).

Coral reefs around the world continue to decline.Corals killed by natural or anthropogenic disturbances are often degraded into rubble. This rubble is dynamic, easily shifted by storms and currents which may forms "killing fields" for coral juveniles, hindering coral recovery. In order to rehabilitate the coral reef, artificial substrates are always used as artificial reefs both for coral transplantation and recruitment. Unfortunately, most artificial substrates are expensive and used material from outside of the ocean (for example concrete/cement base). In order to develop a new low-cost artificial substrate that can be replacing the concrete/cement-base as a media for coral transplantation and coral recruitment, the modified coral rubble were tested in Seribu Islands, Jakarta. Two different net (nylon and polyethylene) were used to form or to shape rubble into a compact shape, stable and strong substrate.The stability of the rubble and the complexity of the surface which is created by the net make this substrate suitable for coral transplantation and coral recruitment. In 6 m, the highest survival was recorded for coral fragments that were transplanted on cement-base (58%). The lowest survival was recorded on nylon + rubble (16%). While, in 10 m, the highest survival was found on cement-base (40%) and the lowest was on polyethylene + rubble (3%). The modified coral rubble is a potential method for coral transplantation and coral recruitment. However, this approach requires testing at additional sites to determine the replicability of the results.

The objective of present study was to determine the optimum level of papain in the diet of keureling fish (Tor tambra). The complete random design was utilized in this study. Six levels of papain dosage were tested in triplicates, i.e. 0 (control); 17.5 mg kg-1, 20.0 mg kg-1, 22.5 mg kg-1, 25.0 mg kg-1 and 27.5 mg kg-1 of feed. The experimental fish were fed the experimental diet two times a day at 8 AM and 5 PM at feeding level of 5% body weight for 90 days. The Anova test result showed that papain enzyme gave a significant effect on the weight gain, daily growth rate, specific growth rate, survival rate, feed conversion ratio and feed efficiency (P<0.05). The Duncan multi-rage test result showed that the higher values for all measured parameters were obtained at the dosage of 27.5 mg kg-1. Therefore, it is concluded that the optimum dosage of papain enzyme for keureling fish was 27.5 mg kg-1 of feed.How to CiteMuchlisin, Z. A., Afrido, F., Murda, T., Fadli, N., Muhammadar, A.

Global warming is caused by increased carbon emissions into the atmosphere resulting from burning oil, gas, and other fossil fuels. Subsequently, the carbon gas enters the waters through a diffusion process facilitated by the concentration of gases in the air, which is higher than in the waters. The outcome of this process is a decrease in water acidity, leading to a lower pH, which can disrupt the life of aquatic biotas. Therefore, this study aims to analyze the effect of decreasing of pH on the growth, survival, and physiological conditions of barramundi (Lates calcarifer). To achieve this objective, seven pH levels were tested, namely pH of 7.24 (control), pH 6.74, pH 6.24, pH 5.74, pH 5.24, pH 4.74, and pH 4.24. Every treatment was performed with four replications, and the fish was reared for 30 days in the respective tested pH. The reared madia is sea water with a salinity of 22 ppt. The experiment was conducted in the laboratory of fish breeding Faculty of Marine and Fisheries, Universitas Syiah. The results showed that a decreasing in pH had a significant effect on the growth performance and hematological condition of barramundi (P0.05), but its had no significant effect on survival (P0.05). The experimental fish could survive at pH 4.24, but their growth and hematological conditions were disrupted below 6.24. Therefore, it was concluded that the lower threshold value of pH for barramundi was 6.24.Keywords:Global warmingOcean aciditypHFisheries productionPhysiological disturbance

Indonesia is recognized as one of the territories that have the highest reef fish biodiversity in the world. One of the commercially valuable fish in this area is the groupers (locally name "kerapu"). At least 76 grouper species have been reported in Indonesian waters, with three species were categorized into "vulnerable", five species "Data Deficient", and 68 species under the "Least Concern" category based on IUCN classification. The increasing exploitations rate had been reported caused the grouper stocks in Indonesia to decrease and threatened extinction. However, only limited scientific data is available regarding the grouper in Indonesia, including their identification. In most fish landing sites across Indonesia, the groupers are morphologically identified and recorded as "kerapu" to replace their scientific species names. Accurate species identification is essential in designing appropriate and sustainable management of fisheries resources. One of the tools that have been used in fish identification is DNA barcoding. In the last two decades, this molecular method has been applied to identify many fish groups globally, including grouper fish. This study reviewed the DNA barcoding approach in grouper identification in Indonesia based on the available literature.Keywords:DNA barcodingGrouperMolecular TaxonomyFisheriesIndonesia
