Anyway, then they hatch into alevin. I know, wierd name. But thats what its called. The alevin have a yolk sack attached to them, and (its really wierd.) the yolk sack stays for a few weeks. While the yolk sack is still not absorbed, the salmon stay in the gravel. When its gone, the alevin come out and they are fry now.and here is a pic of alevin!
