Thank you.
Can that be determined by sampling of the returning fish to the river? If those fish are out there for the same period of time they used to be and they're coming back smaller, I can see that there would be a correlation drawn there. Has that science been done to see if the fish just aren't growing to size in the same amount of time, or if they're being harvested, or if there's other mortality before they're reaching that large size? Which would it be? Has the science been done?
