An airplane will also assist with tracking the coyotes as they range across the region. This trapped coyote will provide researchers with important information in a one-year study about the animal's lifestyle. This largest species of salmon can grow to five feet in length and weigh more than 100 pounds, but most chinooks are about 3 feet long and weigh about 20 pounds. Chinooks have been transplanted from the Northwest to other regions of the United States and other countries. They are sometimes called king, spring, blackmouth or tyee salmon and a fishing village on the west coast of Alaska, King Salmon, is named after this popular fish.
Chinooks migrate up freshwater streams from the saltwater of the ocean in autumn.
During migration the salmon can travel thousands of miles to return to the location where it hatched by following an odor in the water. Females dig a hole with their tale and lay as many as 15,000 eggs. Male salmon fertilize the eggs with milt. Male chinooks have kypes, or pronounced hook-shaped lower jaws. After spawning the fish die and are washed down the river.
