Stock Assessment and Rebuilding of Two Major Shrimp Fisheries (Penaeus monodon and Metapenaeus monoceros) from the Industrial Fishing Zone of Bangladesh

The two economically important shrimp species in Bangladesh are the tiger shrimp, Penaeus monodon, and brown Metapenaeus monoceros. However, a continuous decline landing of these from industrial trawling made it critical to assess their stock biomass status explore response present degree removal. Given minimum data requirement robustness, this study employed depletion-based reduction analysis (DB-SRA) fisheries rigorously. For fishing zone (beyond 40 m depth EEZ Bangladesh), estimated historic mean carrying capacity (K) was 5015 metric tons for monodon 35,871 overfishing limits (OFL), which were much smaller than reported catches throughout time series, indicate fisheries. As result, reference year (B2020) both lower BMSY, indicating that not producing MSY. Therefore, rebuilding sustainable management stocks, recommended catch limit 100 P. 750 M. monoceros next ten years projections.
