Rainbow trout are opportunistic feeders and will eat anything from aquatic and terrestrial insects, to fish eggs, to small minnows, to crustaceans and worms. General recommended stocking densities: 600 trout fingerlings per acre of pond surface area. MacIntyre, C., Ellis, T. North, B.P.

AW 1203/F0916: THE EFFECTS OF STOCKING DENSITY ON THE WELFARE OF FARMED RAINBOW TROUT: A NOVEL NON-INVASIVE METHOD FOR MEASURING TROUT STRESS LEVELS by T Ellis1, AP Scott2, C Stewart2, N Bromage3, B North3, M Porter3, C Randall3 1 The Centre for Environment, Fisheries and Aquaculture Science (CEFAS), Weymouth Chilean scientists discovered that chronic stress due to high stocking densities activates proteolytic mechanisms in the skeletal muscle of rainbow trout, leading to weight loss.
