Chinook salmon successful at guarding their redds. Chinook eggs hatch, 90 to 150 days after deposition, depending upon water temperature. Egg deposits are timed to ensure the young salmon fry emerge during an appropriate season for survival and growth. Fry and parr (young fish) usually stay in fresh water 12 to 18 months before traveling downstream to estuaries, where they remain as smolts for several months. Some Chinooks return to the fresh water one or two years earlier than their counterparts, and are referred to as "jack" salmon. "Jack" salmon are typically less than long, but are sexually mature and return at

Salmon are a very resilient species, but human causes are driving them to the brink of disaster as we continue to invade their habitat space. Dams, population growth and other human causes are significantly impacting salmon runs and the way that these organisms live. The life cycle of salmon is a very important factor in conservation.
