y are in the water column prior to settlement. They've found the drifters, which are fitted with satellite transmitters so they can monitor them remotely, travel as far away as Cape Cod and Georges Bank. However, those released in Great Bay estuary tend to remain there, likely to the detriment of the lobster populations.

"The estuary is not the best place for lobster larvae because of the warmer temperatures, higher turbulence and lower salinity," says Watson. "That might explain why there are few mature females there."

Putting all these data into perspective will be Watson's next step. He hopes to apply what he has learned to improving management practices for the species. In particular, Watson wants to know if New Hampshire lobsters can be managed in isolation or if the management unit needs to be larger.

"If our lobsters are leaving for Massachusetts or elsewhere, then we need to work together to better manage the population," he says.
