Stock assessment is essential for sustainable fisheries management. Biological reference points (BRPs) such as F_0.1, F_max, and F_0.5 are essential to fisheries management and are estimated from fisheries and biological data. However, research on the precision and accuracy of these estimates remains limited. This study evaluates the precision and accuracy of the BRPs, which are estimated from ELEFAN (Electronic LEngth Frequency ANalysis) and applied to real data using a bootstrapping approach. Additionally, we examined the minimum quantity of data and survey frequency needed. Reliable estimates require either sequentially sampling for more than 12 months or sampling every 2 months across two years, with both strategies requiring 7,000 to 8,000 data points. This research helps to optimize the length-based survey design. Accurate sampling is essential for generating reliable data that informs management decisions and ensures sustainable fishery practices.
