The whole point of having fish hatcheries is to preserve certain kinds of fish in the wild. But the hatchery fish are well-known for thriving in the controlled environment of the hatchery, and not faring quite as well in the wild.
Which presents issues not just for the hatchery fish, but also for their offspring if they mate with wild fish.
Oregon State University researchers are looking into ways to change the hatchery conditions to raise fish more like the wild ones.
We get a peek at the research in a visit with Professor Michael Blouin and Marc Johnson, acting director of the Oregon Hatchery Research Center.
