An invasion is headed for some of our most precious fisheries. Invasive animals, plants, and even micro-organisms pose a serious threat to ecosystems across the country.
One of the most well known examples are Asian carp which are poised to infiltrate the Great Lakes and devastate native species. In areas of the Mississippi River basin where they have taken over, they now comprise up to 97% of fish biomass. If they get into the Great Lakes, they will starve out walleye, trout, salmon, and other sportfish.
While the Asian carp onslaught rightfully gathers much of the media attention, other invasive species are equally concerning. From sizeable fish like northern snakeheads and lionfish to tiny invaders like zebra mussels and mudsnails, they are all a danger to the health of our precious sport fisheries.
