Stock assessment update for ocean quahogs (Arctica islandica) through 2011

"This assessment update for ocean quahog in the US EEZ is based on fishery-dependent data from 1978 through 2011, NEFSC clam survey data from 1982 through 2011, and biological information. Since this is an assessment update, there are no specific terms of reference addressed. In addition, shell length-meat weight relationships, survey and commercial dredge efficiency, and size selectivity estimates were not updated to include new depletion experiment data collected in 2011 , and assessment models were configured in the same way as in the previous assessment (NEFSC 2009). These types of auxiliary information will be updated in the next ocean quahog benchmark assessment"--Executive summary. by Antonie Chute, Daniel Hennen, Robert Russell, and Larry Jacobson.
