Asian carp [1] are becoming a serious problem for Lake Ontario, where fears abound about the non-native fish's impact on trout and salmon populations, the safety of fishermen and the multi-million dollar fishing industry.

The U.S. Fish and Wildlife Service [2] announced that starting Aug. 9,  people will be banned from importing or transporting silver Asian carp across United States waters. The goal is to keep the carp out of the Great Lakes and stop the spread of the invasive species.

"Anytime you introduce a species that isn't native into a new system, it can have the tendency to crowd out native species," David MacNeill, a fisheries specialist with New York Sea Grant in Oswego, told the Post-Standard [3].

Silver Asian carp eat zooplankton, a staple for many young fish. While alewives (the main food source for trout and salmon) survive on zooplankton their entire lives.
