dc.description.abstract | Fish in many exploited stocks grow faster and mature earlier at either larger or smaller sizes in comparison
to pre-exploitation periods. These changes can be driven by both genetic and phenotypic responses.
At the same time, these stocks may adjust to other changes of the environment such as increasing/
decreasing overall productivity or changes in temperature. Using a model of planktivorous fish with
annual spawning and size- and density-dependent individual growth, we ask if the interplay of environmental
change and fishing pressure could lead to stabilizing, disruptive or directional selection on age and
size at maturation in the stock. This question is particularly relevant for habitats exposed to significant
directional change in the environment, the prime example being many man-made inland reservoirs. | no_NO |
