Intertidal Crabs on Rocky Shores
Entry ID: gomc_259

[ Update this Record ]

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.
