The final salmon egg taking of the season will be available for the public to view at the Nimbus Fish Hatchery next week, according to hatchery officials. Egg-taking combines eggs from euthanized female fish with milt, which contains sperm, from male salmon. The fertilized eggs are then submerged in a water tank and later taken to a holding area in the hatchery to continue the fertilization process. The egg-taking is done to aid in the conservation of the species. …  Although late in the season, dozens of Chinook salmon can still be seen swimming up the fish ladder at the hatchery’s visitor center. After the conclusion of salmon spawning, the ladder will remain open through the winter for the migration of steelhead trout.
