Factorial Aerobic Scope Map (IMAGE) Radboud University Nijmegen Caption Based on their insights, the researchers have identified – in great detail and worldwide – which fish are likely to thrive in which bodies of water, from oceans to small rivers. "We calculated this for two 'hypothetical' fishes, one large and one small. Small fish do well in warm environments, such as the tropics, and large fish do better in colder regions. We may also be able to extend these projections in the future to calculate the effects of environmental change." Credit Radboud University Usage Restrictions Credit must be given to the creator.
