Abstract
Aquaculture of salmonids in open systems is among the climate and environmentally friendliest forms of animal food production. Climate change potentially threatens the sustainable production of highly valued cold water fish species, such as salmonids, in flow-through systems. By calculating the relationship of site-specific recorded water temperature with hydrological characteristics, air temperature, solar exposure, and precipitation, this study predicts temperature dynamics of five temperate cold water aquaculture facilities under projected climate change in four scenarios. Air temperature correlated with study site water temperature, and, under reasonable assumptions, two of the five facilities were predicted to face critical warming by mid-century. Extreme rain events induced acute short-term increases in water temperature of up to 5 °C. Artificial shading was associated with significantly lower warming, roughly equal to the projected increase induced by climate change. Complementary niche modelling revealed that 37–77% of current cold water facilities will likely incur suboptimal climate conditions by the end of the century. Shading of raceways, more efficient water usage, and disease management are proposed as key actions to preserve cold water aquaculture.
