Abstract:
Demersal stock potential, total allowable catch (TAC), and exploitation level status in
the FMA 573 were assessed and determined by the National Commission of Stock Assessment
(KOMNASKAJISKAN) through Ministerial Decree No. 19/2022. However, the fisheries status,
i.e., the biomass level concerning the BMSY and the effort level compared to FMSY, was not
completely determined. This study demonstrated the alternative approach to determining
fisheries status under limited data. Statistical time series production and existing CPUE data were
used to perform the Bayesian Surplus Production Model (cMSY). Based on the results, the stock
of demersal fisheries in FMA 573 is overexploited, whereas the F/FMSY and B/BMSY are>1
and <1, respectively. The situation needs concern from all stakeholders. Rebuilding the stock
formulation scheme through harvest strategy development for demersal fisheries in FMA 573
must be prioritized to ensure the sustainability of the stock and the fisheries business. Ansprechpartner Weitere Information im WWW
