"We have to go where the lobsters want to go... the rockier, the craggier, that's where we want to be putting our traps," says Ali Desjardin, as she pulls up a lobster trap from the ocean floor.She grabs a gauge to measure the area from the rear of the eye socket down the length of the back.Any lobsters kept must have backs between 3.25 inches and 5 inches (12.7cm) long.Everything else is returned to the sea.Females carrying eggs are also tossed back, a regulation Maine lobsterman put in place in 1872.Lobstermen notch females with a v to indicate to other fishermen that they are needed breeders.A purple rope, known as a line, attaches the trap to a floating buoy.Allegations about this line are rocking the entire lobster industry in Maine.Earlier this month Monterey Bay Aquarium's Seafood Watch, a California programme which advises consumers and businesses on what marine life to eat, placed the Atlantic lobster on its "avoid" list.According to Seafood Watch, the lines used in lobster fishing can entangle the endangered North Atlantic right whale.Outraged Maine lobstermen say they have not had an entanglement with a right whale in nearly two decades.
