Human population effects on genetic diversity of salmonid fishes

  • Mathisen Ole A. 
I. General Impacts of Human Population Growth on Inland Waters (c) North America


Almost all members of the Pacific Salmon have an anadromous life history with reproduction, egg development and juvenile feeding taking place in freshwater. This makes salmon vulnerable to human activities like logging, dam building, agricultural irrigation and hatchery activities. Initially the effect was local and minor in nature. Lately with expanded pen farming and ocean ranching of salmon, some species like pinks and chums, are being moved between streams or from one location to another on a scale not anticipated earlier. The interaction of enhanced and wild stocks of salmon is potentially reducing genetic diversity, which universally is considered necessary for maintaining healthy stocks of salmon. A possible solution is to establish salmon sanctuaries without any enhancement activities.
