Spiny Dogfish
Squalus acanthias
Partially verified
Handling & regulations: Not managed under the Atlantic HMS shark program this site's other shark entries cite — spiny dogfish falls under a completely separate federal fishery plan (NOAA's Greater Atlantic Region, coastwide annual quota, fishing year May 1–April 30). As of NOAA's own current guidance there are no recreational possession restrictions in federal waters, though state rules and a general saltwater fishing license still apply. The two rear-facing dorsal spines can cause a real puncture injury — handle with care, supporting the body rather than gripping near the fins, whether releasing or keeping a legally retained fish.
Commonly confused with: Smooth Dogfish (Smoothhound Shark). If you're not sure which one you've caught, treat it as the more restricted species and release it until you can confirm.
Identification
Two dorsal fins, each with an ungrooved spine directly in front of it — the feature that gives this species its name and its main defensive hazard, Characteristic white spots scattered along a gray back, white underside, Slim, narrow body with a pointed snout — genuinely different species from the already-published smooth dogfish despite the shared "dogfish" name
Where this fish fits
These are discovery categories describing where anglers realistically fish for this species, not a guarantee this project has confirmed regional access at every listed setting — see the linked locations below for this project's own actually-sourced spots.
- Typical season
- Most abundant in cooler months (fall through spring) as large schools migrate seasonally with water temperature — a common incidental catch from piers, jetties, and boats.
- Habitats
- Inshore and offshore waters from Maine to Florida, most abundant between Nova Scotia and Cape Hatteras
- Food use
- Eat with caution
Data not yet verified.
This site hasn't checked for a fish-consumption advisory covering this species yet. That is not the same as confirmed safe — check current official guidance before eating your catch.
Seasons, size limits, and possession limits change and vary by water body. Always check the current regulations at NOAA Fisheries — Atlantic Spiny Dogfish before you fish.
- Bait & lures
- Cut bait fished on bottom — almost always an incidental catch while fishing for other species
- Beginner difficulty
- Easy for beginners

Identification features (dorsal spines, white spots) and the separate-management/no-federal-possession-restriction status were directly confirmed via NOAA's own Atlantic Spiny Dogfish species page as of 2026-08-16. Habitat/season notes remain general regional knowledge, not individually fact-checked.
