Replacement of dietary fish oil for Atlantic salmon parr ( Salmo salar L.) with a stearidonic acid containing oil has no effect on omega-3 long chain polyunsaturated fatty acid concentrations
The worldwide increase in aquaculture production and the concurrent decrease of wild fish stocks has made the replacement of fish oil in aquafeeds an industry priority. Oil from a plant source Echium plantagineum L., Boraginaceae, has high levels of stearidonic acid (SDA, 18:43, 14%) a biosynthetic...
