Abstract
A tag was developed and tested for the long-term marking of spiny dogfish (Squalus acanthias). The tag is retained without corrosion and with minor skin abrasion. They have not been lost from fish held in captivity for up to 3 years. Most recoveries were in the immediate release area, but some fish were recovered 250 to 7,000 km from the release area. The greatest distance travelled (7,000 km) was by a fish tagged in June 1980 in Queen Charlotte Sound and recovered in November 1982 off the northeast coast of Japan. The recovery rate for fish tagged and released in the Strait of Georgia and standardized for catch suggested that movement of spiny dogfish throughout their range is an important aspect of their biology. Less movement was exhibited by fish tagged in the Hecate Strait region. However, of the fish that did move, the majority were recaptured off Washington and the west coast of Vancouver Island and not in the Strait of Georgia.
