Abstract
Lake Poso has high eel potential and a strategic position in supporting the development of eel fisheries in Sulawesi. Lake Poso is out of 15 national priority lakes in natural resources and environmental management programs. The catch of eel from Lake Poso is reported to have been decreasing for the last twenty years. Several factors causing the decline in eel populations are fishing activities, disruption in migration routes, and other factors such as changes in habitat and environmental conditions. The sustainability of the life of the Poso eel is determined by the success of the eel migration process. The migration of adult eels to the sea and young eels from glass eels to freshwater habitats must continue. The perspective plans that can be done to manage Poso's eel resources include 1) Socializing the eco-biological characteristics of eels as catadromous fish; 2) Establishing conservation areas and regulation of eel fishing; 3) Increasing eel population through restocking 4) Integrating fisheries and aquaculture activities; 5) Developing eel culture technology through size segmentation production; 6) Developing an eel migration monitoring system; 7) Building a cross-sectoral forum and put a joint action program; 8) Proposing the Poso eel Research and Conservation Center.
Highlights
Lake Poso is located in Poso Regency, Central Sulawesi
Lake Poso is located in Poso Regency, Central Sulawesi Province, at a geographical position of 1o 44'- 2o 04' S and 120o 32'- 120o 43' E, at an altitude of ±600 m above sea level [3]
Poso Regency Regional Regulation No: 8 the year 2012 concerning Spatial Planning of Poso Regency for 2012-2032 stipulates that the Tomasa River area is designated for eel conservation area [27]
Summary
Lake Poso is located in Poso Regency, Central Sulawesi. The area of Lake Poso is 323.2 km, while the area of Poso's catchment area is 1271 km2 [1]. The outlet of Lake Poso is the Poso River, which flows to Tomini Bay, and the length of about 52 km [1,2]. Research on eel management began to be carried out due to the decreasing eel population, which affected the production of eel fisheries. In Indonesia, the decline in eel population and eel fishery production has begun to decline, as is the Poso, Central Sulawesi [7, 12]. The built management model requires a comprehensive understanding of eels' biological and ecological aspects, including habitat conditions and migration processes between marine, estuaries, and freshwater ecosystems. Socio-economic conditions and the institutional role of eel-catching business actors must be considered These factors significantly affect the use of resources. This paper contains thoughts on managing eel resources in Poso waters by reviewing the research results carried out and are currently being conducted. The purpose of the preparation of this paper is to provide input and suggestions for sustainable eel management
