COSEWIC Assessment and Status Report on the Spiny Dogfish Squalus acanthias, Atlantic population, in Canada

Spiny Dogfish (Squalus acanthias) is an easily identified small shark, with spines in front of both dorsal fins. The colouration is typically grey-brown with irregular white spots on sides and back. In the northeast Atlantic, the species is commonly referred to as spurdog. In French it is known as aiguillat commun. This report treats the Atlantic Ocean population as a Designatable Unit (DU). The Pacific DU will be dealt with in a separate report.
