Free salmon publication offered
August 2, 2012
UAF fish geneticist, Tony Gharrett, has spent his prolific career exploring how Alaska's
most commercially important fish species, salmon, is affected by natural and human-induced
genetic changes. Now he has summarized his knowledge in this free online publication
series. With writing laced with wry humor and written for high school level and above
science readers, Gharrett reviews basic Mendelian genetics, describes the role genetics
plays in fisheries conservation and management, and hits the lowlights of how Columbia
River salmon populations were profoundly affected by dams. Gharrett dispassionately
outlines the pros and cons of salmon hatchery practices, the real and potential effects
that genetically modified organisms may have on naturally occurring populations, and
how Mother Nature may be involved in transgenics, the moving of genes from one organism
to another. Gharrett will continue to expand this online publication.Download your copy online today.
