Web1.1.6 Variability in chemical composition. A problem which may be encountered with the use of certain feed ingredients, and in particular with animal and plant by-products and wastes, is that their chemical composition may vary considerably over relatively short periods of time and from one locality to another (Blair, 1974; Tacon and Ferns, 1979). WebThe solids are mostly protein and stickwater can contain as much as 20 per cent of the total solids in the fish so that it is normally well worth recovering. The material is recovered by evaporating the stickwater to a thick syrup containing 30-50 per cent solids, and sometimes marketed separately and known as condensed fish solubles.
