What’s happening to the lobster babies? Portland dealer will pay to get an answer

Scientists want to know why the number of lobster babies in the Gulf of Maine is declining when their numbers at every other stage of their life cycle remain high. That question is considered so important to the future of Maine’s $1.5 billion lobster industry that one of Maine’s 200 lobster dealers – Ready Seafood of Portland – is funding a university study to investigate what some scientists call the big disconnect. “What’s happening to the babies?” asked Brendan Ready. >click to read< 14:18

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
