Background and objective: The productivity of fishing in marine waters provides an overview of the level of ability of the fishing gear used by fishermen to obtain optimal fish catches. This study aims to determine the productivity of fishing in locations around the construction of the coal-fired power plant, Jepara Indonesia. Methods: The method used is a descriptive method which is a case study. This research case is about annual marine fishery productivity by calculating Catch Per Unit Effort (CPUE), then predictions are made using simple regression analysis. Results: Based on the results of the study, a positive modeling trend (increase) was obtained for total fishery production, total demersal fishery production, and total pelagic fish production. Conclusion: capture fisheries productivity in Jepara waters is generally quite good and is not affected due to the development of Tanjung Jati coal-fired power plant B-Unit 5 -6. This is because it is not a fishing operation area for fishermen so there is no potential conflict with fishermen. Suggestion: The results of this study can be used by the Government of Jepara Regency in determining sustainable fishing policies and not overfishing
