TRANSGENIC SALMON FOR CULTURE AND CONSUMPTION

Over the past 20 years we have generated stable lines of transgenic Atlantic salmon possessing either antifreeze protein (AFP) genes or a salmon growth hormone (GH) gene construct. The AFP transgene is expressed and AFP secreted into the blood of all generations to date. However antifreeze protein l...

Description
Summary:Over the past 20 years we have generated stable lines of transgenic Atlantic salmon possessing either antifreeze protein (AFP) genes or a salmon growth hormone (GH) gene construct. The AFP transgene is expressed and AFP secreted into the blood of all generations to date. However antifreeze protein levels remain low and a means to improve these levels needs to be developed. Our GH transgene enhances growth rates to the point where Atlantic salmon can reach market size (4-6kg) a year earlier than can non-transgenics grown commercially in Atlantic Canada. The characteristics of the transgenic salmon are described, and the hurdles to be overcome before products derived from transgenics can take their place in the world 5 market are discussed (Fletcher et al 1999b).
