Air-Conditioning Could Save Overheated Fish

A new outline presented by the Coastal Hydrology Lab at Dalhousie University in Nova Scotia, Canada suggests that a new river flow experiment could help save Canada’s Atlantic Salmon population. Avid Off-Shore Fisherman Rob DiNoto shares the details:

Due to rising temperatures in the water, Canada’s salmon population has declined drastically.  Research points to various causes.  Mainly, acid rain, overfishing, pollution and damming have impacted the fish most of all.  Recently, a new threat has lingered in the water: rising water temperatures.  As an Avid Fisherman, Rob DiNoto has witnessed this massive shift in the fish population, firsthand.  In recent years it has become increasingly apparent that the overall environment and weather conditions appear to have a much greater impact on the fish population than even overfishing.  The problem, unfortunately, only continues to get worse.

Rob DiNoto has recently discovered that the Coastal Hydrology Lab at Dalhousie University has suggested a solution that could help save the Atlantic salmon population.  That suggestion is to combat high water temperatures with a passive technique that will redirect a portion of the river’s flow.  This would be effectively achieved through implementing an underground trench, which would allow the water to cool off before it returns to the flow of the mainstream.  This could achieve a 20 degree reduction in temperature, Kathryn Smith, doctoral candidate at Coastal Hydrology Lab explains.
