Rainbow trout with six-pack abs and burly shoulders have emerged from a University of Rhode Island laboratory, and could someday find their way to humans' dinner tables. That's assuming diners don't panic at the sight of the muscular ichthyoid awaiting their knives and forks.
The bodybuilder stature of the trout comes from turning off myostatin, a protein that normally slows muscle growth. Researchers had known of a natural myostatin mutation that allowed for 20 to 25 percent more muscle growth in Belgian blue cattle, but did not know if the same would apply to the different mechanism of muscle growth in fish.
Terry Bradley, a fisheries and aquaculture expert at the University of Rhode Island, worked with a group of grad students for 500 hours to inject 20,000 rainbow trout eggs with different DNA snippets designed to block myostatin.
About 300 eggs ended up carrying the gene for more muscle growth, and eventually produced fish that mostly have the six-pack ab appearance -- even though the fish don't have standard abdominal muscles. A big dorsal hump adds the appearance of muscular shoulders.

If the transgenic trout meet FDA approval, they could join the 1,000 trout farms that churn out about $80 million worth of trout each year. Such fish also appear to display normal behavior for now, despite a faint resemblance to the Street Sharks.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.

Just think if somebody gets the bright idea to add the myostatin blocking gene to those flying asian carp from the great lakes. It will be like some 200 lb muscle bound leviathan from the deep jumping out and smacking you in the face.
WTF!? 3/3
that just..no
A faint resemblance to the Street Sharks?LOL
That has to be the most gruesome, lumpiest, most unappetizing, gag-reflex producing Frankenstein of a fish I have ever seen.
It ain't comin' to my dinner plate.
What were these people thinking?
If they want to "feed the world" they could try to select trout that produce more offspring or something more normal along those lines.
These fish are just plain gross.
These may work if they don't sell them unbutchered. You wouldn't know the difference between this and your normal fish stick.
Like mom always said, don't knock it before you try it.
Many animals have been selectively bred or engineered in similar ways. Turkey's are a good example. Go to a turkey farm and compare the turkeys you see there with wild turkeys. You'll notice a big difference. Farmed turkeys have been selectively bred to increase the size of the breast. These turkeys are slower and completely incapable of flight, and even look weird when compared to wild turkeys. Yet we still eat these 'mutated' looking turkeys.
Turkeys aren't the only example, just about all domesticated animals have undergone some kind of physical change as a result of selective breeding, even animals that aren't traditionally used as foor (at least in the western world). Dogs are a good example here. Breeds like bulldogs didn't get their appearance naturally, they were selectively bred over generations to achieve that appearance.
While these fish might have an odd outward appearance, once the meat has been removed from the rest of the fish, it would likely resemble a normal filet, or possible even be trimmed to resemble a normal filet, with the scraps used for other purposes (pet foods, popcorn fish, etc.). You might say its not coming to your dinner table, but you might bring it home anyway without even knowing it was a lumpy trout.
25% more muscle mass, same food consumption, naturally breeding, inheirited trait - that sounds like a recipe for an invasive wipe out of "heritage" trout in the wild
Well, i find this somewhat odd.
You whiny babies have eaten uglier things in your life than that fish, I'm sure. Your all missing the bigger picture here. What about sport fisherman that just want to have a little fun. I wanna see one of those fish on a hook. I bet they could put up one hell of a fight. He he he. LOL
Does this have a nutritional benefit I don't eat alot of fish. Is rainbow trout fatty or something. Obviously it might bump up the protein because the is more lean muscle man. My other question is when do humans get these modifications. I've wanted a myostatin modification ever since I learned about super babies.
wow I clearly cant type.
...uh no.

It's not that surprising, we have already modified chickens to un-natural sizes.
When someone mentions trout and "six pack" in the same sentence, I recall a lot of good times out by the lake.
Now, if they can get a trout to come out of the lake with a few frosty ones, I'm thinking that's not a bad thing...
This fish may look very ugly but that dose not mean that it will not Increase profit. Obviously this is what the company is wanting, the fish has alot more meat on its bones. It is the same type of fish and will most likely taste the same as a normal samon there will just be more meat.
i just wanna know if it still tastes like fish. hopefully none escape into the wild. I do wanna see them in a shark tank slappin one around though. I'd place a few wagers on that fight.

uh no...I can't imagine walking in to my local grocery store and seeing these things laying on a bed of ice next to the salmon and crab.But I'm thinking that's not a bad thing...

It is really interesting news that Rainbow trout with six-pack abs and burly shoulders have emerged from a University of Rhode Island laboratory, and could someday find their way to humans' dinner tables. It’s a brilliant idea that muscle growth can be increased without in taking more food by just blocking the myostatin. All the claps are to Terry Bradley for this brilliant idea. He has successfully mutated some trout fishes by turning off the myostatin protein production. It’s really good news for the trout farmers that the fish grow faster, besides having 15 to 25 times more muscle without eating more food. I wish transgenic trout will meet FDA approval soon.Pet Medications

I would like to go fishing to catch such fish. It's so great!!!
