Modelling fishing-induced evolution in pikeperch (Sander lucioperca) and vendace (Coregonus albula), Lake Oulujarvi, as template for ecosystem model.

ABSTRACT: Fishing-induced evolution can impact fish trait distributions, with previous studies highlighting declines in size and age at maturation. However, the effects on fish growth remain less understood, and different fishing methods may exert distinct selection pressures on populations. This study explores the impact of gillnetting on pikeperch (Sander lucioperca, Percidae) and trawling on vendace (Coregonus albula, Coregonidae) modelled using data-based normally distributed selection curves and the Allometric Trophic Network with Evolution model (Perälä & Kuparinen). Simulating evolutionary changes caused by fishing, we specifically examined the parameters of the von Bertalanffy model, including asymptotic length L∞ and Brody's growth coefficient k . In the model we simulated a negative correl
