With concerns growing over a likely bait shortage in the lobster industry in Maine and Canada due to a drastic cut in the upcoming season's herring quota , Nova Scotia resident Patrick Swim has a possible solution. Swim thinks he can solve the bait shortage by harvesting an invasive species. Silver carp is one of the four species of the invasive Asian carp silver, bighead, grass, and black that have placed the Great Lakes water system at risk. Carp were brought to North America in the s as a biological control of algae, plants, and snails in aquaculture sites. Subsequent flooding allowed them to escape their pens, which created a new problem for the environment and marine life. A mature meter-long carp can weight 40 kilograms and consume up to 40 percent of their body weight each day, which puts stress on resources for native species.
