22565 Atlantic Surfclam and Ocean Quahog Survey Data Set Published / External 22558 Dredge Surveys Project Completed The standardized NEFSC Atlantic Surfclam and Ocean Quahog Survey has covered an area from Cape Hatteras to Georges Bank. The survey was conducted every two or three years and currently, a subset of the survey area is completed annually, with the entire survey area completed every three years. The dredge had been operated in a consistent fashion using the same survey protocols and gear from 1982 until 2011. In 2012, the platform was changed to an industry vessel, which resulted in a gear change from a 5' hydraulic dredge to a 13' commercial style hydraulic dredge. Five-minute tows are made at stations that are randomly selected to provide unbiased abundance measurements. Station data includes: shipboard sensors, including ship speed and position, dredge angle, voltage and amperage of electrical current that powers the pump on the dredge (through 2011), manifold pressure, water depth and temperature. Biological data includes: catch weight, catch number, lengths, weights, and meat weights. The purpose of the NEFSC Atlantic Surfclam and Ocean Quahog Survey is to provide indices of abundance and recruitment of surfclams and ocean quahogs. Cooperative deletion experiments have been an important part of surf clam stock assessments since the NEFSC (2005) assessment following the 1994 survey. Depletion studies are conducted in collaboration with academia and the clam industry. An industry vessel fishes repetitively to "deplete" a site where the R/V Delaware II has already made a small number of non-overlapping tows.
