Tough GM salmon lose their nerve in the 'wild'

Transgenic fish that behave ferociously in a bare tank, appear meek under more natural conditions, meaning it will not be easy for biologists to predict the ecological consequences of escaped GM animals. Salmon genetically engineered to overproduce growth hormone can put on up to 25 times the weight of wild salmon and could provide "aqua-culturists" with a faster way to raise fish to market size. However, lab tests suggested that transgenic fish are more aggressive predators than wild salmon, raising concerns that they could harm native fish if they escape into the wild. Stream tanks Fredrik Sundström and colleagues at Canada's Center for Aquaculture and Environmental Research, Fisheries and Oceans, in Vancouver, tested whether the GM fish would have the same superiority in more natural conditions.....
