A randomized field trial was conducted across various regions to measure yield improvements using new methods compared to existing practices. The analysis employed linear regression models to quantify network performance and accuracy. Notably, the study revealed a $2\%$ improvement in yield measurement (95% confidence interval: 1-3%) when utilising the enhanced monitoring system, suggesting significant potential for policy reform and broader application. This research introduces a novel methodological approach for evaluating and enhancing regional fishing yield measurement systems, contributing to more accurate fisheries management practices in Tanzania.
