Yes, mercury is a huge issue. Seafood retailers have long glossed over the issue. The longer a speicies lives, the more mercury is bioaccumulated. We all know that long lived pelagic species sucah as tuna and swordfish have mercury. I was shocked to see the advisories for lake cumberland bass in the last KY fish and wildlife book. Where is the public outcry?? Mercury levels in freshwater species is not just an outdoorsman issue, but a public health issue and should be addressed.
