SSN VIEW: SUPPORT Adoption of Proposal SPINY DOGFISH POPULATIONS ARE IN DECLINE WORLDWIDE, DUE PRIMARILY TO OVER-EXPLOITATION BY TARGETED FISHERIES AND BYCATCH. The spiny dogfish (Squalus acanthias) is a small, highly migratory shark found in temperate and boreal waters in the northern and southern hemispheres, including the Northwest and Northeast Atlantic, Northwest and Northeast Pacific, South Atlantic and Southeast Pacific. S. acanthias occurs on the continental shelf from the inter-tidal to the shelf slope. Spiny dogfish are usually found in large aggregations just above the seafloor. S. acanthias is among the most vulnerable of all shark species to overexploitation, owing to its aggregating habit, late maturation, low reproductive capacity, longevity, long generation time and extremely low intrinsic rate of population increase. It falls into FAO's lowest productivity category for commercially exploited aquatic species. Information from stock assessments, analyses of catch and landings data, and trawl and longline surveys show that spiny dogfish populations are in decline. Trend data for the northern populations of S. acanthias show declines ranging from 40% to 99% over a variety of ...
