Here's the choices. They can sell them to the buyer for (probably) dog food or fertilizer. They can bury them or use them in nutrient enhancement although most of those are done in the fall (spring would would work super). Or, they can plant them in lakes and some will be caught and some of the anglers will be happy.

None of the options are perfect.

I think, as Rivrguy alluded to, that some time pent getting them back to feeding and using females as the primary stocked fish would improve success. That would take some time and some money.
