A new study of the genetic profiles of wild and hatchery coho salmon demonstrates important distinctions in how the two types of fish form mating pairs.
These findings by Oregon State University researchers provide new insight into subtle differences between wild and hatchery fish that could lead to changes in how hatchery fish are mated to promote the success of hatchery fish and conserve and protect wild fish.
“Genes can give us insight that we could not perceive using human sensory perception. I can see differences in size and color, but genes give us information about things we can’t see, hear or feel,” said Heather Auld, a post-doctoral research associate at Oregon State University’s Coastal Oregon Marine Experiment Station and the study’s lead author.
“If we can learn more about how natural origin fish mate in the wild, and if that differs from how hatchery fish mate in the wild, we can potentially gather new information to improve mating strategies applied in hatcheries.”
