“…Species risk index (SRI) was 1.64 for L. obsoletus, 1.54 for S. canaliculatus and 1.55 for C. miniata (Table 3). The estimated species risk index has also been reported for several commercial species caught by trammel nets in Korean waters, ranging from 1.20 to 1.64 in 2000 [17]. L. obsoletus has the highest SRI due to the operation of gillnet gear, which tends to damage coral reefs, and none of the mature adult fish was found in the gillnet fishing area, while C. miniata has a lower SRI due to the hand line being operated in the deeper areas and having a less environmental impact than gillnets.…”

As the Seram Laut Island (SLI) community relies on coral fish resources, changes in coral fish populations will impact their income and nutritional needs. This research aimed to investigate the SLI ecosystem's status using risk score indicators and the management implications for the sustainability of the coral fish fishery ecosystem. This research used the tier 2 approach semiquantitative ecosystem-based fishery assessment (EBFA) method based on a risk score of 0 to 3, with four objectives: sustainability, habitat, biodiversity, and socio-economy. Several high-risk scores in the red zone were found in the fishing efforts indicator of Lethrinus obsoletus, Siganus canaliculatus, and Cephalopolis miniata, catch per unit effort (cpue) indicator of S. canaliculatus, maturity proportion, and fishing gear impact of L. obsoletus and S. canaliculatus and habitat quality indicator of S. canaliculatus. Coral fish's species risk index (SRI) ranged from 1.28 to 1.64 (yellow zone), with L. obsoletus having the highest SRI. The coastal of SLI's ecosystem risk index was in the limited range (yellow zone). For ecosystem sustainability, proper management should be developed with a focus on the indicators in the high-risk state (red zone) by spatial planning for coral and habitat conservation, as well as policies based on local wisdom.

“…Regarding the strategic role and potential prospects of coastal and marine ecosystems and natural resources, various obstacles and trends threaten sustainable carrying capacity, including anthropogenic factors (Yeon et al 2011;Miah 2015). Human activities that threaten the sustainability of fishery resources come from the use of fishing gear that is not environmentally friendly and differences in fishing ground areas that can cause conflict in the community.…”

Abstract. Daris L, Massiseng ANA, Fachry ME, Jaya, Zaenab ST. 2022. The impact of fishermen’s conflict on the sustainability of crab (Portunus pelagicus) resources in the coastal areas of Maros District, South Sulawesi, Indonesia. Biodiversitas 23: 5278-5289. Using environmentally unfriendly fishing gear causes damage to coral reefs and seagrass, which are the habitat of crabs. The prohibition on using ecologically unfriendly fishing gear, such as mini trawl, in catching crabs and shrimps in the coastal area of ??Maros District, South Sulawesi, Indonesia, has triggered horizontal conflicts between traditional fishermen from 1985 until now. This study aims to identify the types of fishing conflicts and analyze the distribution of conflict areas and the maximum fishing rate that could threaten the sustainability of crab (Portunus pelagicus) resources. This research was conducted from February to July 2022 in the coastal area of ??Maros, South Sulawesi Province, Indonesia. The type of data is primary and secondary data. The data collection methods used in this study were observation, interviews, and Participatory Rural Appraisal (PRA). The analysis data used qualitative by reducing and presenting data obtained from observations, interviews, and PRA, as well as spatial analysis and Geographic Information Systems (GIS) to describe the distribution map of fishermen's conflicts. The results showed that the types of conflicts between fishermen using crab resources were agrarian conflicts, technological conflicts, and perception conflicts between fishermen using trammel nets and traps and fishermen using mini trawls. Conflicts between fishermen in resource utilization crabs occur between ??2.71-3.26 km from the coast during dark moons and 2.17-3.26 km during bright moons. Fishing conflicts have an impact on decreasing crab catches from 2015 until 2021, where the fishing effort (trip) has exceeded the sustainable fishing effort (MSY) by 690 trips/year with a total catch of 1232.3 tons/year.
