Habitat
Smooth dogfish inhabit coastal waters of the western Atlantic Ocean, from shallow bays and estuaries to depths of about 200 meters over continental shelves. They prefer sandy or muddy bottoms and are commonly found in temperate to subtropical regions. Their range extends from Massachusetts in the north to Argentina in the south.
Diet
Smooth dogfish primarily feed on small fish such as menhaden and herring, as well as squid, crabs, and shrimp. They are opportunistic bottom-feeders that hunt in schools, often at night when they forage along the ocean floor. Feeding behavior includes ambushing prey in murky waters.
Behavior
Smooth dogfish are social sharks that form schools for protection and feeding, often migrating seasonally to follow food sources or warmer waters. They are primarily nocturnal, active at night for hunting, and exhibit minimal territorial behavior. These sharks are generally non-aggressive towards humans and are curious but not dangerous when encountered.
Fishing
As a hardy shark species, the smooth dogfish offers exciting recreational fishing opportunities along the Atlantic coast from Massachusetts to Florida and southward to Argentina, particularly in coastal waters, shallow bays, estuaries, and over sandy or muddy bottoms at depths up to 200 meters; target them by bottom fishing with medium-heavy rods, reels spooled with 20-30 lb test line, and sturdy hooks to handle their strong runs, using bait like cut fish, squid, or shrimp to mimic their natural diet of small fish and crustaceans. Effective techniques include anchoring and waiting for bites or slow trolling near the seafloor, with the best seasons being late spring through fall when waters warm and they school for feeding, and prime times at night when they're most active; aim for individuals up to 5 feet and 37 pounds 8 ounces, with the IGFA all-tackle record standing at 37 pounds 8 ounces caught off New Jersey in 1983, showcasing the thrill of this sport fish. Conservation-wise, smooth dogfish are listed as Near Threatened by the IUCN, so anglers play a vital role by practicing catch-and-release for most fish to support population stability, adhering to regulations like minimum size limits and bag restrictions in U.S. waters as effective management tools that ensure sustainable fishing and protect shark habitats through angler-funded programs.
