Australia To Use GM To Control Carp

mskfisher writes "Yahoo! News is running an AFP story on Australia's efforts to control the carp population using a 'male-only' gene. The gene will prevent the carp, considered a pest in Australia, from producing female offspring. The carp has wiped out some 90% of the native south Australian fish population, namely perch and bass. They do not, however, mention any ways of controlling the spread of this gene in the wild, besides the obvious death of any affected population."
