This assures easy access to the feed and will help to achieve size uniformity within the population. Do not introduce the feed too close to the tailscreens or it may be washed out before the fish have a chance to eat it. Though the use of a published feeding chart is strongly recommended, charts are only guides and individual judgment should be exercised based on observations. Do not overfeed. Once feed settles to the bottom of the tank, small trout will ignore it.
Excess feed leads to deterioration of water quality and promotes disease.
Remove excess feed promptly. After fingerlings are moved out to tanks or earthen ponds, a variety of feeding alternatives is available. Hand-feeding is generally not practical on a large commercial farm, except in certain situations. Examples include training fish to use demand feeders or administering medicated feed to sick fish. Several types of automatic and mechanical feeders are available for trout farming, including electric, water powered, and solar powered feeders with variable timers.
