STONINGTON, CT - 17 July 2012-071712EC06-- After a lobster is measured, rubber bands are placed on its claws and it is thrown into an awaiting tub. For four generations, the Maderia family out of Stonington has been commercial fishing off the coast. The state Department of Energy and Environmental Protection announced last week that it has launched a study into why the state's lobster catch has dwindled from 3.7 million pounds in 1998 to just 142,000 pounds in 2011. The Maderias say this year has been one of their best in a dozen years. Erin Covey Republican American.
