Patterns of genetic inheritance and variation through ontogeny for hatchery and wild stocks of Chinook salmon

Creator:

Hulett, Patrick L.

Abstract:

Although differences between selective pressures in hatcheries and streams have been theorized to cause genetic divergence between hatchery and wild salmonids, evidence of this is lacking. This study was initiated to document the presence or absence of genetic change in hatchery and wild stocks by characterizing genetic traits in fish...

Masters Thesis
Rearing density as a driver of adaptation to captivity and traits under selection by domestication in hatchery reared steelhead (Oncorhynchus mykiss)

Creator:

Thompson, Neil F.

Abstract:

Releasing hatchery reared salmon and steelhead to supplement threatened and endangered populations is a widely used conservation tool. One issue with this strategy is hatchery fish have lower reproductive fitness than wild fish when spawning in the wild. One of the drivers of fitness loss in steelhead is adaptation to...
