Coral reef conservation has become a topic of growing global attention, in line with the increased awareness of the importance of coral reef ecosystems for marine life and humans. The establishment of environmentally conscious local communities requires a sustainable approach. Training, education, and community empowerment programs need to be implemented to enhance understanding of the importance of coral reefs and to engage the community in conservation efforts. The issue in the ecotourism area of Tobololo Village is the lack of groups or communities that care about coral reefs, mainly because the local community does not yet understand the functions and benefits of coral reef ecosystem services. Community service activities carried out in Tobololo Village included outreach and education, the formation of a local community, and the introduction of coral reefs. The results showed that the outreach activities educated the community about coral reefs, emphasizing that they are living organisms capable of reproduction and that they have both ecological and socio-economic functions and benefits. Additionally, a local community named KOMPAG (Komunitas Masyarakat Peduli Terumbu Karang) was established.

This research aims to determine growth patterns, gonad maturity levels, gonad maturity index and size of first mature gonads. The research was carried out for 5 months starting from November 2023 to March 2024 with the sampling location at PPN Ternate. Data collection used the observation method (direct observation). The data was analyzed using Microsoft Excel. The results of the sex ratio for male and female escaped fish were 1: 1.36, indicating that the catch of fish was balanced at 1: 1. The results of the analysis of the relationship between length and weight showed that male and female escaped fish were allometrically negative, where there was a faster growth in length than weight gain. The level of gonad maturity in the yellowtail (Caesio sp.) (males and females) experienced the highest gonad maturity in March with the number of mature gonads in male fish amounting to 46,49% and the number of mature gonad in fish amounting to 54,04%. The hight gonad maturity indeks value in male and female escaped fish occurred in March. Based on analysis of the gonad maturity indeks (IKG), the fish with the highest TKG was found in TKG IV with a value of 1,8526. the avarage size of mature gonads for male fisht is 252 mm and famale fish is 243 mm.

This study aims to analyze the length distribution and sex ratio of bullet tuna (Auxis rochei) landed at Ternate Archipelago Fishing Port Ternate (PPN Ternate). Sampling was conducted in June and July 2024 with 100 fish per month. Observations included total length measurements and sex identification to determine size distribution patterns and sex composition. The results showed that male fish in June had the highest frequency at class interval of 190-201 mm, and in July it shifted to class interval 226-237 mm. Meanwhile, female fish in June were dominant in the class interval of 201-210 mm, and in July increased to the class interval of 231-230 mm. The sex ratio in June was 1:1.22 (male:female), while in July it was 1:0.82. The results of the chi-square test showed that the difference in sex ratio was not statistically significant (p > 0,05), so the population was considered to have a balanced sex composition. This finding is in line with several previous studies in the Indonesian region that showed variations in size structure and sex ratio of Auxis rochei influenced by seasonality, reproductive migration, and fishing activity. This study provides important basic information to support sustainable management of bullet tuna (Auxis rochei) resources in North Maluku waters.

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

The level of fishing efficiency and capacity of a fishery provides a useful instrument for policymakers to design management and control the response of the fishing industry to management. For this reason, fishing efficiency and capacity measures must be applied appropriately depending on a particular fishery's management and specific characteristics (Espino et al., 2006). This study aims to determine the efficiency of fishing capacity in mini purse seine in Ternate City. This research uses a descriptive quantitative method, DEA (Data Envelopment Analysis), to measure the technical efficiency of production (fishing capacity)—efficiency analysis using Microsoft Excel supported by frontier add-ins. The mini purse seine units that became Decision Making Units (DMU) were 20 DMUs consisting of 11 DMUs in Rua village, and 9 DMUs in Moti sub-district, Ternate City. Load capacity, fishing trip, fuel volume, number of crew members, and engine capacity are input factors in this study, while average production volume is the output factor. The results showed that 13 mini purse seine business units (13 DMUs) in Ternate City were inefficient (<1) and 7 mini purse seine business units were efficient. Most of the mini purse seine fishing capacity in Ternate City showed an inefficient condition (<1). The inefficient condition is caused by the excessive use of inputs (fishing capacity). Potential improvements can be made by reducing the use of inputs to obtain maximum output. Trip catch, fuel volume, and number of crew are production inputs that can be improved for optimum output in mini purse seine fishing in Ternate City. This research contributes to understanding best practices in using mini purse seines while supporting efforts to achieve economic sustainability in the capture fisheries sector in Ternate City.
