The Sockeye Salmon have all moved inland up a shallow creek in Alaska, USA to their spawning grounds where they display their red coloring which glistens in the sunlight. Before the salmon enter the fresh water spawning grounds, they stop feeding and survive on their body fat. It takes the salmon weeks to fight their way through rapids, rocks, falls and other obstructions until finally making it into the calm waters of the creek where they were originally born.
Their body coloring changes to red and their head becomes a pale green hue after leaving the saltwater and entering freshwater. The trip to this calm creek is quite a work out for the Sockeye Salmon, many who show up here badly bruised and beaten.
The female salmon digs a nest with the movement of her tail in the bottom of the creek to make it just right, sometimes taking weeks to perfect where she lays up to 8,000 eggs. The male salmon will then fertilize them and the female then covers them up again with gravel where she will stay until she dies.
During the winter, the eggs are incubated where they grow until ready to hatch. They remain under the gravel for 3 to 4 months until emerging as fry in May or June, once again starting the life cycle of the Sockeye Salmon.
