...gene splicers have cooked up a replacement that sounds like a fish tale: a veritable superfish, one that can grow at least twice as fast, resist disease and outmate competitors. If approved, it could provide protein to millions of people at a time when fish stocks are perilously low. But as you might expect, some critics are carping. They consider the supersalmon a biological time bomb that could destroy the remaining natural salmon populations and wreak other environmental havoc. To them, the supersalmon is nothing less than a "Frankenfish...
...knows what ripple effects might occur if the new supersalmon escaped into the wild. One of the few studies done by U.S. researchers found a lower survival rate for eggs produced by transgenic fish. Still other studies show that despite their name, so-called superfish have diminished muscle structure and swimming performance. Says Canadian fish geneticist Robert Devlin: "Science, at the moment, is unable to give us a reliable assessment of risk...
