STONINGTON, CT - 17 July 2012-071712EC01-- Travis Maderia has a brief wait in between stops Tuesday morning as his father drives to various points to pick up lobster traps. On the right is a bin of skates which are used as bait. For four generations, the Maderia family out of Stonington have 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.
