Study of Bali Sardinella Stock (Sardinella lemuru) Landed at Nusantara Fishing Port (PPN) Pengambengan, Bali – Indonesia

Bali sardinella (Sardinella lemuru Lemuru) is a type of small pelagic fish that has important economic value in Indonesia. In Indonesia, this fish is widely used to be processed into pindang fish, sardines and fishmeal. Sardinella lemuru is a pelagic fish found in shallow sea waters, lives in groups, and is a surface species. The suitable habitat for Sardinella lemuru is coastal waters, the largest population of Sardinella lemuru in Indonesia is in the Bali Strait. Sustainable utilization of fishery resources must be immediately applied to resources that are already fully exploited. If this is ignored, fishery resources will become over exploited and even decrease drastically due to uncontrolled levels of exploitation that exceed the carrying capacity of the fishery resources. The ability of fishery resources to renew themselves through growth and recruitment is greatly influenced by the surrounding environment in terms of food resource procurement, competition between and between species, a healthy and suitable environment and the presence of predators. This research was conducted from February 15 to May 15, 2024 by conducting fishing operations using a mini purse seine vessel in the waters of the Bali Strait. The tools and materials used include ships, fishing gear, meters, cameras, navionic applications, and stationery. The purpose of this study was to analyze the potential stock of Sardinella lemuru landed at Nusantara Fishing Port (PPN) Pengambengan. It is hoped that this study can provide information on the potential stock of sustainable Sardinella lemuru based on the length distribution and surplus production model approach at PPN Pengambengan Bali. The graph of the relationship between effort and CPUE produces a linear equation CPUE = -0.0001x + 2.6736 with R2 = 0.0317, this equation shows that the CPUE trend decreases along with the addition of effort value each year, this indicates that the level of fishing effort is getting higher. The CMSY value shows the maximum sustainable production level, namely the highest Sardinella lemuru yield, while the EMSY value shows the optimum level of effort. The results of the average utilization rate show that the utilization of Sardinella lemuru resources has achieved optimum utilization, with an average of 71%. Fishing efforts exceeding EMSY may threaten Sardinella lemuru resources in the Bali Strait.
