ABSTRACT

Various elements of the feeding process has been investigated, such as the effect of feed distribution area, feeding interval, use of feeding signal, self-feeding, color of the food particles, and vertical feeding level. Our experiments showed a better growth with when the feed were distributed over a lag re area of the cage. When keeping the feed ration constant, we found no effect on growth of dividing the food ration in 3, 9 27 or 81 meals pr day. Salmons can quickly learn to react positivly to a visual signal. But the use of such a signal gave no increased growth. Experiments with demand feeders gave lower growth than traditional controled feeding. Salmon fed below the surface grows as well as salmon fed traditionaly from the surface.
