(a) Size of the best day's catch of Gulf groupers plotted against the year in which the fisher remembered landing it (with a second order regression line shown r²=0.62, p<0.001). (b) Mean weight (+95% CI) of the largest Gulf grouper ever landed by three generations of fishers (one-way ANOVA, p<0.001; LSD test, all groups significantly different at p<0.05). (c) Second order regression (r²=0.21, p<0.001) of the weight of the largest Gulf grouper fishers recollected catching versus year in which it was landed.
