Study: Hatchery fish can succeed if bred from wild

 GRANTS PASS, Ore. (AP) -- New research has found that a hatchery using wild
salmon to spawn the next generation can help rebuild endangered salmon runs
without passing on genetic problems that threaten future generations.
   The study, published Monday in the online edition of the scientific journal
Molecular Ecology, contrasts earlier research suggesting that hatcheries themselves
genetically select for fish that go on to fail once they are released into the wild.
   Researchers from the Columbia River Intertribal Fish Commission tracked an
endangered run of chinook salmon in a tributary of the Salmon River in Idaho.
   Shawn Narum, lead geneticist for the commission, says the study shows hatcheries
 can be an important tool to prevent endangered salmon runs from blinking out,
but he adds that healthy salmon runs still need healthy habitat.
