The GAM trend-line of record catches size (total length) in the 50-year dataset. The GAM fit has been computed with the stat_smooth function. The data suggest: A unimodal response in the native crucian carp (Carassius carassius) with time B increase maximum attainable size in the invasive gibel carp (C. gibelio) C stabilised size limits in common bream (Abramis brama) and D maximum in 1990 in roach (Rutilus rutilus).
