Thesis: Climate driven oxygen stress in fishes along a rapidly warming coast

Globally, our warming climate is lowering dissolved oxygen in the oceans and thus negatively impacting marine wildlife and fisheries. Aquatic organisms are oxygen limited and the predicted global declines in dissolved oxygen of 7% by 2100 are a major cause for concern. Oxygen stress affects large fish first and is particularly important to species with high metabolic requirements. If symptoms of chronic oxygen stress are present in smaller fish then oxygen stress may have a greater effect higher up through the trophic web.

Physiological indicators of oxygen stress such as blood-chemistry and pH is examined in fish species along WA's coastline.

Why my research is important

This project aims to investigate how climate change is impacting upon the physiology and ecology of fish.
