Book Description
Salmon in sea cages are exposed to high water temperatures and low dissolved oxygen levels (i.e., hypoxia) that are predicted to worsen with climate change. I examined the impacts of an incremental temperature increase (1°C/week to 20°C or 23°C) and moderate hypoxia (~70% air saturation) on the production characteristics, cardiac morphometrics and haematology of farmed Atlantic salmon (Salmo salar) of Saint John River origin under laboratory conditions. While temperatures up to 20°C had few negative effects on the salmon, hypoxia significantly reduced feed consumption and growth, and further temperature increases adversely affected the fish. Specific growth rate and feed consumption dropped dramatically after 20°C, and mortalities began at 21°C and reached ~ 30% by 23°C. Salmon exposed to high temperature alone had increased relative ventricular mass (by 21%), whereas those exposed to high temperature and hypoxia had a 15% greater blood oxygen carrying capacity. This research suggests that further increases in coastal ocean temperatures may negatively affect farmed salmon production, especially if combined with hypoxia.

Book Description
This project is developing methods to provide sea surface temperature forecasts for Tasmanian salmon farm sites at lead times of up to four months (for example in September, predict January conditions). Preliminary site-specific forecasts are being delivered monthly to the Tasmanian salmon industry.
