DMC researchers test technique to determine lobster’s age

Research professor Rick Wahle and graduate student Carl Huntsberger are testing a technique at the University of Maine Darling Marine Center to determine the age of lobsters. Unlike fish, mollusks and trees, Wahle says lobsters and other crustaceans molt—or cast off their skeletons thereby discarding external signs of growth. That means a lobster’s age is estimated on size, but it’s a rough determination because ocean conditions affect the crustacean’s growth rate. Not knowing a lobster’s age is problematic for scientists and fishery managers seeking to measure the health of the fishery and the sustainability of the stock. Continue reading the story here 10:06
