Thanks, I found a study done by the wisconsin DNR on SMB spawning and recruitement. They taged tons of fish in a small lake that had zero migration. They came up with estimates on SMB reproduction, I still need to read the rest of it.
There was another paper that used genetic testing to see what percentage of nesting SMB males fathered the YOY. It was very low, around 5% I beleive. That means most of the nesting males didn't contribute to the year class.
It makes you think twice about relying on SMB.
