(a) Number of species mentioned by each generation of fishers as depleted (Kruskal–Wallis test, χ₂²=37.7, p<0.001). Boxes show median, 5, 25, 50 and 95th percentiles of the data; dots show range. (b) Number of sites mentioned by each generation of fishers as depleted (Kruskal–Wallis test, χ₂²=39.0, p<0.001). (c) Sites mentioned as depleted were coded as coastal (1) or offshore (2). Mean scores (+95% CI) show a significant shift from the mention of mainly coastal sites by old fishers to more offshore sites amongst the young generation (Kruskal–Wallis test, χ₂²=12.0, p=0.002). In total, old fishers listed 95 sites as depleted by fishing, middle-aged fishers 72 sites and young fishers 40 sites.
