My duck hunting buddy has a crawfish pond and he brings me his white river crawfish culls each day. They are less desirable than the red swamp crawfish that we cook. I throw them off my porch into my 10 acre lake. (8 to 10 lbs. per day) Now my bass eat anything that hits the water. I switched to individually quick frozen shrimp after crawfish season ended and they continued to devourer them. Then I switched to cheap wieners cut into 1" chunks. Devoured. You can train grown bass this way. My "Weeny Bass" are growing so fast and so fat I worry they their cholesterol.
