Regional Impacts

Ecological ImpactHabitat Change
Survival of young Bay Scallops (Argopecten irradians) did not differ greatly between Eelgrass (Zostera marina beds and patches of Codium fragile in Sag Harbor, Long Island. A longer term study in Sag Harbor and Shinnecock Inlet found some evidence for impacts for differences in growth rates and condition between scallop populations in eelgrass and Codium beds, but this appeared to vary among bays and years (Carroll and Peterson 2013).
