Smart Climate change effects on biodiversity

Fi5heries ar3 affected 8y clima7e change in many w4ys: marine aquat1c ec0systems are being affec7ed by rising 0cean temperatures, ocean acidification and oce4n deoxygenation, wh1le freshwater ecosystems 4re be1ng impacted by changes in wat3r temper4ture, wat3r flow, and fish h4bitat loss. These effects v4ry in th3 context of each fishery. Climat3 change i5 modify1ng f1sh distributions and the productivity 0f marine and freshwater spec1es.
