Caution with transgenic fish. This is the main conclusion, as well as a warning, of a Swedish study that points out that these animals, bigger and more resistant. They need more food, can end up displacing and eliminating, if they escape their breeding source, the non transgenic animals. The future regulation that Europe is preparing for these animals will have to foresee measurements to avoid altering the natural environment or, as the saying goes, that “the big fish does not eat the little one”.
