Freshwater streams supply important natural environment for many salmon species. While they are young, they feed on earthbound and aquatic insects and other shellfish or parasites. Salmon eggs are placed in deeper water with larger pebbles where its need good water flow and suitable cool temperatures to supply oxygen to develop embryos. In the early life stages of the salmon, its mortality is usually high due to its predation and changes in global such as siltation, low oxygen concentration, high water temperatures, loss of stream cover and reductions in river flow.
