My ichthyologist buddy, Howard Reisman, who lives in North Sea, says that, notwithstanding the monthlong occupation of North Sea Harbor and other inlets and coves of the Peconics, the alewives are out there and ready to move in to Big Fresh Pond as soon as their passageway thaws. They have been arriving annually at this time every year like clockwork for at least a half-century and most likely for several centuries. The streamway connecting the harbor to the pond can be high or low, depending upon the standing level of the water in Big Fresh.
