I stumbled across this website while surfing for catfishing information: Catfish Science .
Interesting article about using sheepshead for flathead bait. I tried it a couple of times last summer without any success but I am thinking of giving it more of a test this summer. It seems to make sense that sheepshead would be a good part of the flathead forage base considering their abundance in the St Croix, Mississippi and Minnesota rivers. When you are strapped for flathead bait you know you can always count on sheepshead to be available.
