Fig. 1.
Kobe plot of exploitation (F/FMSY) and stock size (B/BMSY) relative to sustainable levels for 43 stocks fished by UK fishers in 2018. The green quadrant (n = 15) illustrates stocks that were sustainably harvested and of a healthy size. In contrast, the area in red (n = 13) indicates stocks experiencing ongoing overfishing at a stock size too small to deliver MSY. The yellow area (n = 11) represents a transition towards green and the amber zone (n = 4) transition towards red (source data [32]).
