in the Northwestern Atlantic
Derived from the NEFSC Spring Bottom Trawl Surveys
This shows relative dogfish stock weight and location. Yellow circles indicate dogfish are present, larger circles indicate more dogfish, plus sign (+) indicates sampled area where no dogfish were found.
The information displayed here represents a timeseries collected consistently since 1968. The Northeast's resource survey constitutes the world's longest and most comprehensive standardized measure of distribution and abundance trends in commercially harvested finfish.
