Generalized additive model (GAM) plots for the additive effects on the catch weight (grams) for (a) all species, (b) Nemipteridae, (c) Nemipterus nematophorus, (d) bycatch; and partial effects on (e) all species, (f) Nemipteridae, and (g) N. nematophorus using hook size, and quarter as an explanatory variable. Shaded areas in the spline represent the 95% confidence intervals.
