CFF employs the Industry-based HabCam v3 towed instrument system to conduct an optical survey of the scallop resource in the Nantucket Lightship (NLS) scallop management area. This survey builds upon recent optical surveys of the large scallop recruitment event south of the Great South Channel and follows four previous surveys (2013, 2014, 2015, and 2017) conducted by the HabCam Group and Coonamessett Farm Foundation, Inc. (CFF). The survey will be used to provide estimates of the abundance and distribution of sea scallops, culminating with a preliminary estimate of total and exploitable biomass. The primary objective of this survey is to document the distribution, survival, and growth of sea scallops, with particular attention to the 2012 year class. Additional information will be gathered on the distribution of potential scallop predators, bycatch species, and substrate in the areas of the optical transect.
