Oysters: A complicated economy and ecology

NORWALK  Conn– It’s 6:30 a.m., and the oyster boat Grace  P. Lowndes was making its way to oyster beds just a mile or two off the  Norwalk harbor. The trip only takes two hours. There are two boom-mounted dredges, one port,  the other starboard. The dredges are lowered one at a time to the beds, raking  the bottom for less than a minute. Then they’re hauled up, their loads of  oysters dumped on the steel-plated deck. continued
