The goal of this anthropological investigation is to examine how fishing technology innovation in Banjar Regency relates to local knowledge. Using ethnographic techniques, such as participant observation and semi-structured interviews, this study was carried out over the course of six months, from January 2022 to June 2022. Interviews were conducted with 30 people, including 20 fisherman, 5 fish traders, and 5 representatives of the local administration. Following that, the concepts were put into categories. The study's conclusions shed light on the nuanced interplay between conventional wisdom and cutting-edge fishing techniques and showed that local communities ought to be included in the management of freshwater resources. The study also emphasizes the value of striking a balance between profitability and sustainability in fishing methods and emphasizes the necessity for ongoing research and cooperation between government organizations, academics, and local people to overcome the difficulties of sustainable fishing methods. Overall, the results point to the necessity of integrating traditional knowledge into contemporary fishing methods for sustainable fisheries management, and show that excessive reliance on fishing equipment has led to the loss of fish populations and the degradation of the freshwater ecosystem.
