In his research, Eggleston also found that Oregon Inlet is a critical ocean-to-estuary link through which millions of post-larval crabs enter the North Carolina sounds. "We need to be careful about possibly altering water exchange through this vital link," he says. "Recent proposals to build jetties outside the inlet would be great for boating and fishing, but the impact on crabs is unclear. Jetties may actually enhance the transport of crabs from offshore into the sound or they may reduce transport or have no effect at all. We need further study before we build ; To get the most up-to-date informa- tion on Eggleston's blue crab research, visit the Web at eos/info/mea/mea469_info/bluecrab/. ? COASTWATCH 33.
