Atlantic cod
Species that are over-fished, such as the variants of [[Atlantic cod]], are more susceptible to the effects of climate change. Over-fished populations have less size, genetic diversity, and age than other populations of fish. This makes them more susceptible to environment related stress, including those resulting from climate change. In the case of [[Atlantic cod]] located in the [[Baltic Sea]], which are stressed close to their upper limits, this could lead to consequences related to the population's average size and growth.
