Hypoxia, which can occur naturally, is exacerbated in marine cages due to restricted water movement and locally increased biomass. Even apparently minor reductions in dissolved oxygen concentration can result in decreased growth, appetite, immune function and fish welfare. The aim of my research was to improve our understanding of the dynamics of dissolved oxygen fluctuation in salmon cage aquaculture so that managers can focus mitigation efforts and minimize risk as the industry continues to expand. Tina was enrolled at UTas and co-supervised by Barbara Novak. She is now a researcher at the Institute of Marine Research, Norway.
