Effects of growth hormone transgenes on the behavior and welfare of aquacultured fishes: A review identifying research needs
Expression of a growth hormone (GH) transgene can achieve dramatic impacts upon the performance of aquaculture stocks, for example, increasing the growth rate of coho salmon 11-fold. With the prospect of improved production efficiency, some aquaculturists want to produce transgenic fish commercially. Commercialization of transgenic fish and shellfish, however, poses not only ecological, food safety, […]
Ethical decisions concerning animal biotechnology- what is the role of animal welfare science
Scientists recently attracted considerable public attention when they presented a featherless chicken tailored for production in hot climates. Although this chicken was actually the result of traditional breeding, it is an example of what might be achieved if targeted gene manipulation techniques become widely applied in agriculture. Through interfering directly with an animal’s genome, scientists […]
