A difference between chum and coho salmon may be in their blood – Watching Our Waterways

Good new information from science on salmon. This kind of basic science can lead to proper decision-making processes in government. A good example would be to force more work on eliminating stormwater pollution over other kinds of water pollution, focusing funding on that.

Chris Dunagan in Watching Our Water Ways writes about the latest research into why coho salmon are more susceptible to stormwater pollution than chum salmon. In an interview with researcher Jenifer McIntyre, he writes: “Researchers in Japan have discovered that different kinds of fish have different subunits in their hemoglobin, which are the proteins in red blood cells that carry oxygen to the vital organs. Since coho and other salmon may have different forms of hemoglobin, oxygen transport in the blood is a good place to start this investigation, she said.”
