Wild at heart: programs to diminish negative ecological and evolutionary effects of conservation hatcheries

Megan Osborne, Thomas Dowling, Thomas Turner & Kim Scribner
Hatchery programs are critical for conservation and management of many imperiled fishes. Most traditional aquaculture programs negatively affect ecological performance, genetic, and phenotypic diversity of hatchery-origin fish compared with wild counterparts. Here, we synthesize outcomes of three conservation programs aimed at enhancing ‘wildness’. Each program focuses on a different species: lake sturgeon, razorback sucker, and Rio Grande silvery minnow. These species differ in key life history traits including size and age at sexual maturity, reproductive...
