NEFSC 2002 Surfclam and Ocean Quahog Survey (DE0206, EK500)
The 2002 region-wide survey for Atlantic surfclam (Spisula solidissima) and Ocean
Quahog (Arctica islandica) was conducted in continental shelf waters, from Delmarva
Peninsula to Georges Bank aboard the FRV DELAWARE II. The survey, conducted by the
NMFS Northeast Fisheries Science Center, provides indices of abundance and recruitment
for both species. In addition, tows were made at 25 non-random sites during the survey
to support on-going scientific studies.
