Kobe plot that reveals the retrospective evaluation of fishing pressure (F/FMSY) against relative biomass (B/BMSY) for different data using methods: Catch Only, three types of methods to calculate proxy-CPUE indicators (Gross Vessel Count, Gross Vessel Power, and Targeting Vessel Count). Each method presents data points over multiple years in the F/FMSY vs. B/BMSY space. Each plot is divided into four zones representing different levels of stock status: green for sustainable (B/BMSY > 1 and F/FMSY < 1), yellow and orange for caution (either B/BMSY < 1 or F/FMSY > 1), and red for unsustainable (B/BMSY < 1 and F/FMSY > 1). The shaded area indicates the joint confidence intervals.
