Results of the simplified regression models assessing linear and quadratic relationships between removal pressure through angling and population responses (90% quantile fork length (mm); 90% quantile mass (g); total abundance (ind PASE−1); abundance of small-bodied (FLe < 60 mm), medium-bodied (60 mm ≥ FLe < 90 mm), and large-bodied individuals (FL ≥ 90 mm) (ind PASE−1); and biomass (g PASE−1); n = 10). Significant P-values are displayed in bold
