In these areas, fishermen are also starting to see more warmer-water fish, like black sea bass in the northeast U.S. and red mullet in northern Europe1.

Most lobsters have moderate mercury levels, but scientists found that lobsters in the Penobscot River had mercury levels similar to levels found in canned albacore tuna- a species for which there is a mercury consumption warning. Because of this they have closed the area to lobster and crab fishing for two years.
