Age and growth of the smooth dogfish (Mustelus canis) in the northwest Atlantic Ocean.

In North American waters the range of the smooth dogfish encompasses the Bay of Fundy (only the occasional rare stray) to Florida as well as the Gulf of Mexico.

Biology The smooth dogfish has a very slender body and a prominent spiracle behind the eye.

Fishing The smooth dogfish is easily taken with hook and line using squid or shrimp bait.

Seasonal abundance, growth, and foraging habits of juvenile smooth dogfish, Mustelus canis, in a New Jersey estuary.

The smooth dogfish, Mustelus canis, is a small shark species found throughout the western Atlantic Ocean from Massachusetts to Florida, and in the northern Gulf of Mexico, including Cuba, Jamaica, Barbados, Bermuda, Bahamas, and southern Brazil to northern Argentina.

Recently, commercial harvest of smooth dogfish has increased on the east coast of the United States.

The purpose of this study was to determine the growth rates of smooth dogfish from the northwest Atlantic Ocean by using age estimates derived from vertebral growth-band counts.

Smooth dogfish were collected from NMFS groundfish and longline surveys, Virginia Institute of Marine Science (VIMS) longline surveys, Grice Marine Laboratory longline surveys, the Massachusetts state trawl survey, and by the Massachusetts Division of Marine Fisheries (MDMF).

Smooth dogfish were captured during the Atlantic 1996 and Gulf of Mexico 1995 and 1996 surveys (13 captures).

The mean shark catch rate from these sites was 4.9 shark captures/100 hook hours (4.0/100 hook hours for small coastals and 0.9/100 hook hours for large coastals) with eight shark species captured: Atlantic sharpnose, blacknose, smooth dogfish, spinner, blacktip, bull scalloped hammerhead, and great hammerhead.
