Poso in Sulawesi, primarily the Lake Poso and Poso River, is known as eel (Anguilla spp.) fishing areas. Therefore, research of eel fishing is required as base information for evaluating and determining policies for its activities. The eel fishing research in the Poso area was conducted through primary data observations, secondary data traces, and interviews from April to June 2021. The fishing activities take place in the Lake Poso and Poso River shore and the rivers of the lake inlets. The fishing gear that contributed greatly to the catch was fence traps and spears. The local community’s fence trap called waya is a unique gear only found in this area, and it is installed in Poso River around the lake outlets. The gears block the rivers to catch downstream migration eels. The spear is fishing gear (including for eels) operated at night in shallow waters, especially in the outlets of Lake Poso. The eel production recorded from the Poso areas for the last four years has been 6.7–15.5 tons per year, and the highest production was in Pamona Puselemba.

The demand for glass eel (Anguilla spp.) as a source of seeds for aquaculture activities depended on natural catches continue to increase. It has caused glass eel fishing activities to increase and potentially affect the biological condition and sustainability of fishing activities. The study aims to assess the potential stock, maximum sustainable yield (MSY) and the level of utilization of glass eel in the Cimandiri river estuary, West Java. The data were obtained from data on fisherman catches in the period 2014-2018. Potential stock calculation using the CPUE method is based on the Leslie model. Calculation of MSY based on the surplus production model from Schaefer. Utilization rates are determined based on the percentage of actual catch to the total allowable catch (TAC). The results of the study obtained an estimated glass eel potential stock of 4,575 kg. The maximum sustainable yield (MSY) was 991.20 kg.years−1 and the effort (fMSY) was 1050 trip.years−1. The average of glass eel production was 725.55 kg.years−1 and fishing effort 1031 trip.years−1. The TAC which set at 80% from the MSY was 792.96 kg.years−1. The average of the utilization rate of glass eel reached 91.50%. Utilization rates exceeding the TAC value occurred in 2014 and 2017. Management of glass eel fisheries is needed through limiting fishing efforts and the number of catches.
