Description: Northeast Fisheries Science Center (NEFSC/NMFS/NOAA) bottom longline survey (BLLS) strata, sampled in spring and late fall since 2014. The BLLS targets rocky habitat in the western and central Gulf of Maine. To ensure that BLLS data complements data collected during NEFSC bottom trawl surveys, NEFSC samples in the same areas in that part of the Gulf and uses the same methods for selecting sampling stations within each area. Thirty-eight (38) rough-bottom stations and seven smooth-bottom stations are sampled each season. This results in station density comparable to that of NEFSC bottom trawl surveys, but weighted to sample more stations in structured habitat. The survey provides data on commercially and recreationally important fish species as well as critical information about data-poor species (e.g., Cusk, Atlantic wolffish, Thorny skate, and Atlantic halibut.
