Geneticly Enhanced Salmon

What? Geneticly Enhanced Salmon? Or in other words bigger product, why are they doing this? Is it safe? Is it still healthy? This is what scientists are trying to find out about this new enhanced fish.  In my opinion i wouldnt eat it, they put some chemical IN the fish to make it grow faster. Why would you do that? What if animals geneticly enhanced us? We would be like Godzlillas in human form. Tell me, would you eat it? Whos going to test it? Who will be used to find out if it is a good idea or just dumb?
