Transgenic fish

Patent Granted Genetically modified fish (GM fish) are genetically modified organisms. The DNA of the fish has been modified using genetic engineering techniques. In most cases the aim is to introduce a new trait to the fish which does not occur naturally in the species. GM fish are used in scientific research, and while they are being developed for use in aquaculture food production, as of May 2012 no GM fish has been approved by the FDA for this purpose.
