Gastropods play an important role in coastal ecosystems. In Watukarung, the local people collect marine organisms, including gastropods during low tide to supplement their income. Baseline information on the presence and abundance of gastropods in Watukarung are not available. Our survey collected 173 individuals of gastropod in the intertidal area of Watukarung that represent 8 families, 9 genera, and 13 species. Gastropod diversity index (H') in the three beaches (Ngalorombo, Pasir Putih, and Kasap) show varying values from the categories of low and medium species diversity. Although the data suggest that there should be a dominant species in the ecosystem (E < 0.5), there are no strong dominance species in the community (C < 0.5). Watukarung coastal waters are still in good condition for marine organisms with salinity > 31‰, DO > 8.1 mg/L, and pH > 8. The substrate is dominated by coarse sand. The total organic matter is relatively low (< 2.6%) due to characteristics of the substrate that is dominated by a rocky and sandy substrate. Based on the results, we suggest that Kasap beach can be established as a core zone considering its high diversity and density of gastropods as well as being distant from any residential area, whereas Ngalorombo and Pasir Putih beaches are suitable as usage zones for surfing tourism. We highlight the need for the local community, government, and private sector need to work together to encourage sustainably tourism while reducing environmental impacts in Watukarung.","PeriodicalId":165907,"journal":{"name":"Marine Research in Indonesia","volume":"519 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116335302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The program consists of three research groups; G1: Physical oceanography, G2: Biodiversity, and G3: Marine pollution. Considering the vast geographical area of Indonesia, managing joint research at the national level is challenging. Few active members, lack of funding, as well as the reorganization of research institutions over the last two years, pose more challenges. Funding as an engine of research execution has become highly competitive in recent years; therefore, research groups need to be more active in securing available funding at the national level, such as the COREMAP-CTI demand-driven research program, LPDP research scheme, and INSINAS research fund. From the science management perspective, the regional Core-to-Core RENSEA program needs to adapt to global trends in marine science with closer communication during the planning and execution of research projects. We recommend that joint research projects are developed to have more joint supervisory of graduate students; therefore, the collaboration would result in joint research publications and formal degrees for young scientists at the end of the program. In this way, the JSPS Core-to-Core program would have more significant benefits to the development of coastal science and research cooperation.","PeriodicalId":165907,"journal":{"name":"Marine Research in Indonesia","volume":"23 35","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132273547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent developments of sea cucumber Holothuria scabra hatchery technology have successfully enabled the small-scale enterprise to produce hatcheryreared sandfish for restocking purposes. However, the grow-out phase requires considerable resources including ex-situ grow-out sites, labor, and distribution. This study aims to investigate the suitability of some potential grow-out sites for juvenile H. scabra in North Sulawesi waters. Three traditional sea cucumber fishing grounds in coastal areas of North Minahasa regency in North Sulawesi, i.e., Tanjung Merah, Tasikoki and Makalisung, were examined to determine their suitability as a grow-out site. Several criteria encompassing bioecological (native sea cucumber population, seagrass bed population, competitor/predator), environmental (substrate, protection to weather, water quality, tidal cycle), and technical/support (access, safety, labor) were assessed in each site. Site suitability analysis using a multi-criteria decision-making tool, Analytical Hierarchy Process (AHP), shows that Tasikoki has the highest suitability score (48.94%) followed by Tanjung Merah (27.18%) and Makalisung (23.88%). Tasikoki scores higher than the two other sites in 7 out of 11 sub-criteria, including native sandfish population, seagrass species, substrate, weather protection, safety, and community support. Our finding suggests that Tasikoki is bioecologically, environmentally, and technically the best potential site to be developed for H. scabra juvenile grow-out.","PeriodicalId":165907,"journal":{"name":"Marine Research in Indonesia","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124785863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to investigate the alteration in nutrient contents, growth, and feed efficiency of hybrid grouper Epinephelus fuscoguttatus x E. lanceolatus fasted at different intervals. There were two experiments conducted in this study. The first experiment evaluated alteration in nutrient contents of carcass and liver of hybrid groupers. The fishes were grouped into three feeding regimes: fed daily, fasted at a one-day interval, and fasted at a two-day interval. Each group had 50 fishes with an initial mean weight of 200 ± 11.3 g. The second experiment was to evaluate the growth and feed efficiency of the fishes. Hybrid groupers were subjected to two feeding regimes. The first group (n = 45) was fed daily, and the second group of fish (n = 45) fasted at a two-day interval. The first and second experiments were conducted for one and two months, respectively. The results show that hybrid groupers fed daily have the lowest protein and the highest fat in the carcass compared to those fasted on one- or two-day interval. During the first month, there was no difference between the growth rate of the fishes fed daily and fasted at a two-day interval (32.88 and 32.08%, respectively). However, in the second month, the fishes fed daily have a growth rate of 66.08%, which is 1.4 times higher than those fasted at a two-day interval (48.12%). Altogether, fasting in hybrid groupers could alter proximate contents, slow down growth, and improve feed efficiency.","PeriodicalId":165907,"journal":{"name":"Marine Research in Indonesia","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130462909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the regional effort to monitor the ecological impacts of ocean acidification on coral reef ecosystems, the Intergovernmental Oceanographic Commission Sub-Commission for the Western Pacific (IOC-WESTPAC) has incorporated an interdisciplinary approach that includes monitoring of seawater carbonate parameters, coral calcification, net calcification minus bioerosion, and reef community structure. Currently, there is a need to formulate a standard operating procedure (SOP) for assessing coral calcification over the recent years via coral cores. The SOP needs to yield accurate data in a cost-effective way that can be applied by researchers in the region. High variation of coral calcification parameters between coral colonies warrants a sufficiently large number of samples thus a rapid method for analyzing coral extension rate, skeletal density, and calcification. This paper outlines practical guidelines for assessing coral calcification from the field to laboratory using the three-dimensional computed tomography (CT) method.","PeriodicalId":165907,"journal":{"name":"Marine Research in Indonesia","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116965183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nowadays, the source of docosahexaenoic acid (DHA) is mainly obtained from fish which are extracted into fish oil products. However, the fish oil products still have some drawbacks in term of purity, acceptable flavor for costumers, and also their not environmental friendly production process. As an alternative solution, heterotrophic microalgae can be used as a potential source for DHA due to their excellence compared to fish oil products. The aim of this study is to isolate the heterotropic microalgae that can produce DHA. The heterotrophic microalgae were isolated from mangrove fallen leaves (Rhizophora apiculata) by using direct planting method. The morphology of pure microalgae colony were observed through light microscope and subsequently fermented for 14 days. Fatty acids were extracted and methylated through direct transesterification method. Identification and quantification of DHA were conducted by using gas chromatography. The results were four isolates of heterotropic microalgae, namely MTKC1, MTKC2, MTKC3, and MTKC4. The extract of MTKC2 that only showed the content of DHA with value of 9.2 % w/w. Therefore MTKC2 is a potential source for DHA. The MTKC2 was further identified by using molecular biology method and confirmed as Thraustochytrium aureum.","PeriodicalId":165907,"journal":{"name":"Marine Research in Indonesia","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115232534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
