The GAM trend-line of record catches size (weight) in the 50-year dataset. The fit has been computed with the smooth function with a value of k = 1 to avoid overfitting. The data suggest A unimodal response in the native crucian carp (Carassius carassius) with time B moderate increase in maximum attainable size in the invasive gibel carp (C. gibelio) C relatively stabilised size limits in common bream (Abramis brama) and D fluctuating trend in roach (Rutilus rutilus).
