Lobster, American 
American Lobsters are found off the Atlantic coast of North America from Newfoundland to Virginia. They can grow to a large size of 18kg (40lbs) and reach sexual maturity between 5-10 years old.
American Lobsters are caught in commercial fisheries in the US and Canada with lobster traps, a fishing method that can potentially cause some damage to bottom habitats. American Lobster fisheries likely have a low amount of bycatch, however, entanglements of endangered North Atlantic right whales in lobster fishing gear is a significant concern.
In the US, the abundance of American Lobster varies between regions, being moderate to high in the Gulf of Maine and Georges Bank, but at a critically low level in the Southern New England region. In Canada, the abundance level of American Lobster relative to conservation targets is unknown, but in most populations abundance appears to be stable or increasing. The Eastern Canada offshore lobster fishery has been certified as environmentally sustainable by the Marine Stewardship Council.
