Vegetable-fed salmon still yield healthful fat

Vegetable ingredients can replace much of the fish proteins and fish oil used in conventional feeds for farmed salmon and salmon trout -- without sacrificing the health benefits of consumer products. Scientists have studied the effects on the nutritional benefits of fish raised on a diet that substitutes vegetable feed ingredients for some of the marine ingredients. The AquaMax researchers conclude that fully 70 per cent of the fish oil and 80 per cent of the marine proteins in conventional feed can be replaced with vegetable ingredients without any adverse effect on fish health. Even with such a radically altered diet, salmon appear to retain their value as a good source of fatty acids that are healthy for humans.
