You fellows who aren't sure if you have a forage base of crawfish in your ponds, stocked or not should be monitoring the contents of the harvested fishes stomachs. I used to trout fish religiously and every fish I kept to eat was cleaned at the creeek to determine wha thtey were eating, it was a 50/50 thing to find a minnow or a crawfish in nearly every stomach on a good stream with lots of gravel and Craw habitat. Just a thought. I put a couple hundred young ones in my pond last summer but I figure the perch just made a meal out of them as I hadn't put in enough habitat first, next time will be different.
