New study casts worry about baby lobsters

Eco Watch - The lobster industry in Maine is riding the crest of record prices and a record catch last year. This year, exports of the state's signature shellfish more than doubled last year's sales. But a new study from the University of Maine's Darling Marine Center and the Bigelow Laboratory for Ocean Science found that baby lobsters won't survive in warmer waters.

Southern New England lobster fisheries have already collapsed. The National Oceanic and Atmospheric Association reports that over the past 10 years, the Gulf of Maine has warmed 99 percent faster than any other sea in the world. As a result, cod have virtually disappeared from the region. Lobster, like cod, are a cold water species.

A new study, published in the ICES Journal of Marine Science, details the effect of warmer waters on the larval development of American lobsters. They found that when the water was 5 degrees Fahrenheit warmer than currently found in the Gulf of Maine, these baby lobsters "experienced significantly lower survival." Five degrees is how much the the United Nations' Intergovernmental Panel on Climate Change projects the Gulf of Maine's temperature will warm by the end of the century.
