Overfishing, climate change and pollution have reduced fish populations in Canadian lakes and rivers. While hatchery-raised fish could return numbers to normal, they aren’t as well adapted to their new environments, and there’s been concern that the wild population is “tainted” once it breeds with its domesticated counterparts.
But new research from Concordia biology professor Dylan Fraser, published in the journal Evolutionary Applications, shows that after a few generations of breeding and natural selection, these hybrid fish are genetically as robust as their purely wild forefathers.
Fraser's study garnered headlines in many media outlets including Le Journal de Montréal, Press-News, Science Codex, Science Daily, Technobahn, Science Newsline, Paleoblog, Ag Hut, Topix, Environment Guru, Lockerdome, Scoop.it, Jersey Tribune, Bioportfolio, News Locker, Sci Central, telezkope, regator, Uncle News.Life Sciences World CFZ Daily News, Steve`s News, Great Blue Marble, Unfox News, wordpress.com
