Inanco a local wisdom in endemic fish species conservation in lake Poso

Abstract

Lake Poso is one of the ancient tectonic lakes in Central Sulawesi and is also the main habitat for several species of endemic fish that can only be found in this lake including bungu Poso Mugilogobius amadi (CR) and Buntingi half-duck Adrianichthys kruyti (CR). The threat of changes in catchment areas, pollution, geological phenomena, and overfishing make these endemic fish species very difficult to find. During the implementation of the Indonesian Bird Program with the Imunitas Association, one of the activities was the creation of a semi-natural habitat for fish and other aquatic animals, namely “inanco”. This concept departs from the traditional model but with a touch of modernization that is making rocks with aisles at the bottom of the lake and stacking the wood on it so as to allow for the development and protection and habitat of fish, Sogili (eels) and other aquatic animals and plants. This Inanco is made at a depth of 3-5 meters in a lake with good sunlight intensity and penetrates the bottom of the lake in accordance with hereditary knowledge. This concept was made for the preservation of Adrianichthys kruyti bunting fish, Bungu Mugilogobius sarasinorum, and several small fish species, shrimp and crabs and even snails. As a result, one of the species that is rarely found, Bungu Mugilogobius sarasinorum, is now beginning to be encountered frequently in Inanco locations around the mouth of the Meko and Salukai estuaries on the shores of Lake Poso. Further observation is needed on the impact of “Inanco” practices on endemic fish species in Lake Poso and the importance of identifying local wisdom for the conservation and conservation of endemic fish species in Lake Poso.
