Umpqua Coho Salmon Genetic Pedigree

Creator:

Banks, Michael A., Blouin, Michael S., Moyer, Gregory R., Theriault, Veronique, Whitcomb, Amelia, Loomis, David, and Jackson, Laura S.

Abstract:

Data, pedigrees, reports and manuscripts herein are from an investigation conducted with coho salmon of the Umpqua River in southern Oregon from 2001-2009. They relate to a study investigating several areas of uncertainty about the use of salmon hatcheries to increase the abundance of wild populations. At that time, there...

Offspring of first-generation hatchery steelhead trout (Oncorhynchus mykiss) grow faster in the hatchery than offspring of wild fish, but survive worse in the wild: Possible mechanisms for inadvertent domestication and fitness loss in hatchery salmon

Creator:

Blouin, Michael S., Wrey, Madeleine C., Bollmann, Stephanie R., Skaar, James C., Twibell, Ronald G., and Fuentes, Claudio

Abstract:

Salmonid fish raised in hatcheries often have lower fitness (number of returning adult offspring) than wild fish when both spawn in the wild. Body size at release from hatcheries is positively correlated with survival at sea. So one explanation for reduced fitness is that hatcheries inadvertently select for trait values...
