Aims: This study aims to assess the value sustainable development opportunity of the coral reef fisheries activities in Indonesia from the ecological, economic, and social aspect, with a case study of coral reef fisheries at the coastal area of Ternate Island, using the Sustainability Window (SuWi) approach. Methodology and Results: The data was collected from statistical data from relevant institutions and literature study, which consists of ecological, economic and social data, and analyzed using the Sustainability Window approach to determine the sustainability of the fisheries development. The result shows that the Sustainability Window of the coral reef fisheries in the research area tends to move towards sustainable development, where the national policy in catch fisheries management has an impact on the sustainable development and management of coral reef fisheries at the coastal area of Ternate Island. Conclusion, significance and impact study: The Sustainability Window of coral reef fisheries at the coastal area of Ternate Island tends to move towards sustainable processes, with the width of sustainability window that not too narrow to the coral reef fisheries activities at the provincial and national levels. This condition attaches strings to a precautionary approach in policy decision for the management process, and consideration to the effect that can result from the development policy, both at the provincial and national level. The use of Sustainability Windows approach can provide a new simple way for assessing whether the development has been towards a more sustainable direction or not.

Abstract. As one of the coastal ecosystem, coral reef ecosystem is a magnificent marine ecosystem, where their species richness and composition play an important role for the ability of coral reef ecosystem to respond to the fishing activity and other stressors, where fishing has impacted the fish community, target or non-target reef fish species. The dynamic of reef fish resources, especially the target species, become one of the aspects that must be considered in the management and utilization of the fisheries resources in the coral reef ecosystem and their surrounding area. The purpose of the study was to analyze the dynamics of the target fish in the coral reef fishing activity at the coastal area of Ternate Island, from the growth, mortality and exploitation ratio aspect. The research was conduct from April to August 2018 in the coastal area of Ternate Island. The data sampling was growth parameters data through length and weight measurement. Total sample measure along the research time was 6245 sample (consist of seven family and 11 species). The result shows that the target fish have asymptotic length (L∞) range from 263.16–483.16 mm, with growth coefficient (K) ranging from 0.61–0.92 per year. The theoretic age at length 0 (t0) ranges from minus 0.0825–0.1669 year (equal to 30-61 day). The fishing mortality rate (F) is lower than the natural mortality rate (M), which resulting the exploitation rate (E) for the target fish mostly under 50%, which indicated that the utilization of the reef fishes in the coastal area of Ternate Island is still under-exploited.Keywords: Exploitation rate, Growth parameters, Length-weight relationship, Mortality rate, Stock assessment

Increasing of the fisheries problems, especially the decline of fisheries resources stock, made the sustainable issues become intense discussed in fisheries. The importance of the system indicator for fisheries sustainable development are widely known and have been done in several countries through tremendous effort in their fisheries development. In Indonesia, the assessment of fisheries sustainability has been carried out with various approaches to sustainability assessment, mostly on management status. This study aims to assess the rate of sustainable development and management of the reef fisheries in Indonesia using the integrated index approach of sustainability aspect using the multi-dimensional scaling procedures with a case study of reef fisheries at Ternate Island. The result shows that the sustainable development index of reef fisheries at the coastal area of Ternate Island tends to move toward sustainable development within integrated management from all sustainable dimensions. Dimensionally, economic and social dimensions show a positive trend on sustainable development, while ecological and technological dimensions tend to show the inverse direction. The relationship between economic and social benefits obtained from reef fisheries to improving the community well-being will provide a positive trend for the sustainability of reef fisheries. However, on the other hand, the increase in production can lead to overfishing for the reef fisheries resources. Management policy that integrated every indicator of sustainable fisheries dimension may extend the chance to develop reef fisheries at the coastal area of Ternate Island within the sustainability of the resources and ecosystems management.Keywords: Sustainable development, integrated management, fisheries management, sustainability index, coral reef

The Ecopath mass-balanced model was employed to elucidate the trophic structure and interaction, energy flow, and ecosystem properties of the coral reef ecosystem in the coastal area of Ternate Island. The model comprised 30 functional ecological groups, of which 29 were living groups and one was a group of detritus. The trophic structure of the model exhibited a range of values, from 1.0 for primary producers and detritus to 3.81 for the top predator. The resulting trophic aggregation comprises six effective trophic groups, with the largest energy flow originating from zooplankton and benthic organisms in trophic level II. The transfer efficiency is predominantly derived from detritus organisms, in comparison to that derived from phytoplankton as the primary producer. The ratio of total primary production per total respiration indicated that the coral reef ecosystem was at a developmental stage. The coral reef ecosystem exhibited a low ecological efficiency for the fishery gross efficiency. Mixed trophic impact analysis indicated that predators exerted a negative impact on their prey, whereas planktonic organisms exerted a positive impact on the majority of fish functional groups. The comparison of the model with other studies provided information that could inform the development of appropriate fisheries management guidelines for this area based on ecosystem properties.Keywords:Coral reef ecosystemEcopathEcosystem propertiesTernate IslandTrophic interaction
