The parr/smolt

The parr is like a fry but will or has undergone smoltification which gives them a type of camoflauge ( this occurs after a while of traveling downstream). They have also grown to about five inches and are the last stage of the salmon life cycle before they have traveled into the ocean. DANGERS: the dangers to them include: Hydroelectric dams ,gulls and other birds of prey, and pollution from farms, factories, and citys. NEEDS: they need non-polluted water and someway to bypass hydroelectric dams and they need to have undergone osmoregulation
