Abstract This study examines the potential uncertainty in survey biomass estimates of Spiny Dogfish Squalus acanthias in the Northeast U.S. Continental Shelf Large Marine Ecosystem (NES LME). Diel catch‐per‐unit‐effort (CPUE) estimates are examined from the Northeast Fisheries Science Center bottom...
