Eggs

During spawning,  eggs are deposited by the female in redds (gravel depression scoured out by the adults with their tails). Milt (sperm) is then deposited from the male salmon to fertilize the eggs and begin a whole new generation.  Depending on water temperature eggs will take between 6 to 8 weeks to reach the Alevin stage. See the tiny black spots in the photo? Those are their eyes; the first sign of development.
