Major species shifts within the ecosystem could be acceptable as long as the flow of such products continues.

Fisheries are affected by climate change in many ways: marine aquatic ecosystems are being affected by rising ocean temperatures, [ 2 ] ocean acidification [ 3 ] and ocean deoxygenation, while freshwater ecosystems are being impacted by changes in water temperature, water flow, and fish habitat loss. [ 4 ] These effects vary in the context of ...
