Chinook Salmon Information
Chinook salmon are anadromous fish, meaning they
migrate to the ocean as smolts and return to fresh
water to spawn and then die. In
This native fish is one of the most fascinating fishes found in
Fishery managers have stocked land-locked populations of Chinook in several
Chinook return to their spawning habitat in the fall after one to three years at sea. The female builds a large redd (nest) that may be six feet in diameter and one to four feet deep.
They lay between 4,500 and 10,000 eggs. When spawning is completed, both male and female die. The eggs hatch in the spring and the juvenile fish live the next year in fresh water, except for fall chinook that only live a couple months in fresh water before leaving for the ocean.
Young fish in fresh water eat both aquatic and terrestrial insects. They turn to a diet of fish once they reach salt water. Adults returning to spawn do not eat; they live off their fat reserves.
Regulations require the use of rod and reel when fishing for chinook. In streams, chinook strike bright lures or fresh roe.
In lakes, the land-locked Chinook are caught by trolling flashy lures and/or large flies on down riggers, or by jigging large lures near the bottom.
