Intertidal Crabs on Rocky Shores
Entry ID:
gomc_259
Summary
Abstract:
The Asian shore crab Hemigrapsus sanguineus is currently becoming
established along the rocky intertidal coastline of New England. Crab populations in several localities in Narragansett Bay, Vineyard Sound, and Cape Cod Bay were sampled repeatedly in the spring (May-June) and fall (September-October) to examine temporal changes in crab populations and to determine whether any changes observed were similar at different locations. The establishment of H. sanguineus has negatively affected the abundance of xanthid and green crabs. Waterbody or Watershed Names: Narragansett Bay; Vineyard Sound; Cape Cod Bay Purpose: The objective of the study was to determine whether populations of resident crabs are affected as H. sanguineus becomes established.
