Modifications of fish-management/husbandry practices offer most possibilities for potential to reduce of fish predation. Options Deepening ponds/raceways to a minimum of 3 feet and maintaining steep banks to reduce wading activities Delay moving the fingerlings outside in the spring Reduced stocking levels may lessen the attractiveness of ponds to depredating birds Removal of dead fish Feed sinking pellets to lessen the time the fish spend at the surface Additional aeration may help to improve dissolved oxygen levels thus keeping fish down from the surface
