n-3 Polyunsaturated fatty acids, or digestive derivatives thereof, are used to prevent or treat cold water diseases in farmed fish. Thus, incorporation of such fatty acids, preferably (all Z) 5, 8, 11, 14, 17 eicosapentaenoic acid and/or (all Z) 4, 7, 10, 13, 16, 19 docosahexanoic acid, or digestive derivatives thereof, into the feed for Atlantic farmed salmon has been found to significantly reduce the incidence of "Hitra" disease. |
