• Resumen

  • Genetically engineered salmon can grow more than seven times larger than native counterparts, raising concerns that the super-sizing fish would outcompete their wild cousins if they escaped from their farms. In lab experiments, researchers at the government organization Fisheries and Oceans Canada found that the threat occurs when food is scarce. Meanwhile the nonengineered salmon in mixed tanks suffered in size compared with their counterparts in tanks without the super salmon. Under low-ration conditions, wild salmon alone in tanks survived and even put on weight.
