Transgenic Musclebound Trout with Six-Pack Abs Could Arrive Soon on Your Dinner Plate
A 10-year effort has finally created pumped-up fish for commercial aquaculture 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...
