Pumping cold water into rivers could act as ‘air conditioning’ for fish

Pumping cold water into rivers could act as ‘air conditioning’ for fish

When water temperatures get too hot, fish can become stressed or even die. In rivers, Atlantic salmon and other cold-water species sometimes escape the heat by flocking to cooler areas, which often arise near groundwater springs or relatively cool tributaries. Lots of work has been done to preserve and augment these naturally occurring refuges, said Smith, of Dalhousie University in Halifax, Canada, “but there hasn’t really been an emphasis or focus on if we can create cold-water habitat.”

How has federal protection helped Lake Superior?

How has federal protection helped Lake Superior?

The biggest of the Great Lakes and one of the largest freshwater ecosystems in the world — has remained relatively pristine compared to the other four. It’s far enough away from the populated urban centres in southern Ontario, its watersheds are largely forested, there’s little industry or agriculture on its shorelines and its especially cold water (an average of 4 C year-round) has kept away invasive species.

Morning Start: There’s no difference between hot and cold water during laundry

Morning Start: There’s no difference between hot and cold water during laundry

Fun Fact: Because of advances in soap and detergent, there is no difference between using hot water and cold water when washing clothes. The only difference is you’re spending more money using all that hot water because approximately 75 per cent of energy used in a load of laundry is to warm the water.
