Data from: Effective size of a wild salmonid population is greatly reduced by hatchery supplementation

Mark R. Christie, Melanie L. Marine, Rod A. French, Robin S. Waples & Michael S. Blouin
Many declining and commercially important populations are supplemented with captive-born individuals that are intentionally released into the wild. These supplementation programs often create large numbers of offspring from relatively few breeding adults, which can have substantial population-level effects. We examined the genetic effects of supplementation on a wild population of steelhead trout (Oncorhynchus mykiss) from the Hood River, Oregon, by matching 12 run-years of hatchery steelhead back to their broodstock parents. We show that the...
