the alevin are the stage of when the eggs hatch. there are slightly transparant and come in some differant colors. they have a small yolk sack attched to their upper body. DANGERS: some of the dangers to alevin include: Gulls, Dippers, Sculpins and other predators, and another danger is having no gravel or other substance that they can hide in and being crushed. NEEDS: they need gravel or some other substance to hide them and they also need most of the smae things aas eggs so they need plants to help prevent soil erosion and cool, clean water and trees to provide shade to cool the water, but they dont need food because they have the yolk sack which provides food for about a month.
