Pond Boss Forums MANAGING AN EXISTING POND Corrective stocking Caged fish

Like Bill and Sprkplug said, smaller mesh needs cleaning more frequently for sufficient water flow through the cage. Every time you clean the cage, you stress the fish, and stressed fish grow slower than non-stressed fish. You might also want to put a floating feed ring in the cage so the floating feed isn't pushed out of the cage by the feeding fish.

I put a arborists deer or bird netting on top of the cage to prevent herons from standing on the cage edge and using the fish in the cage for an easy meal.
