Alternative lipids research

The concomitant replacement of fish meal and fish oil in marine fish feeds by more sustainable terrestrial alternatives is problematic due to the limited capability of marine fish to synthesize physiological essential long chain n-3 and n-6 highly unsaturated fatty acids (HUFAs) from shorter chain fatty acid precursors present in vegetable oils. Aquaculture program members and other researchers at NWFSC have studied the limitations of replacing fish oil in sablefish diets with sustainable lipid sources.

In particular, researchers have investigated:
