Replacement of marine proteins and oils in feeds for carnivorous fishes such as salmonids has been identified as a key research area. Alternative proteins and oils from vegetable and terrestrial-animal sources can effectively replace marine products, although often growth is the only criteria used to assess their potential. On few occasions has the health of the animal been considered. This research aimed to evaluate what effect alternative protein and oil sources had on growth, immune function and disease resistance when fed to Atlantic salmon, Salmo salar L., parr. Locally available proteins from vegetable and terrestrial-animal sources were initially 'screened' by feeding to salmon to determine any deleterious effects on blood chemistry or immune function. While no significant differences (P> 0.05) were observed, data suggested certain proteins stimulate immunoglobulin production compared to fish meal-fed controls. In a short term experiment, four of these proteins (corn gluten, dehulled lupin, feather ...
