Title: What fishing actually selects for?
Abstract: Fishing-induced evolution has been a topic of wide interest among evolutionary biologists, ecologists and fisheries management. Several models stemming from adaptive dynamics as well as individual and bioenergenic models have been developed and utilized to estimate the eco-evolutionary impacts of fishing. The main idea in fishing-induced evolution is that they target on large body size, such that selective removal of these individuals should reduce the age and size at maturity in the target population. Based on simple reasoning, one could argue that these are expected outcomes of fishing. However, there can be also unexpected eco-evolutionary consequences of fishing. In my talk, I will show examples for unexpected impacts of fishing at the levels of population demography, phenotypic evolution, and population- and ecosystem dynamics. My talk combines empirical and model-based results and demonstrate that harvesting of natural populations and ecosystems can have far more complicated consequences than previously expected.
