A spillway screen must be constructed to keep the fish in the pond while water is running across the spillway. Screens are about two feet high and reach across the width of the spillway. Screens can be made from one inch plastic or plastic coated wire mesh, supported by steel posts. Horizontal metal bars spaced one inch apart and welded into a frame also make good fish barriers, and are less likely to clog with leaves and other debris than mesh screens. Flesh is white, flaky and mild.
Intermuscular bones are present but easily removed in large fish.
