Satellite Tagging of Shortfin Mako in the Northwest Atlantic

Project Status:

In Progress

Type of Initiative:


Project Location:

Atlantic Canada

For which Shark Species:

Shortfin mako shark (Isurus oxyrinchus)

Project Description:

Shortfin makos are most commonly caught by commercial longliners directing for swordfish or tuna, who consider them to be a high-value bycatch. Conventional tagging studies suggest that makos are highly migratory, and are only seasonal residents of Canadian waters. To better understand mako movements into and out of Canadian waters, 24 satellite tags will be attached to makos in 2011 and another 20 in 2013. The results of the study should greatly improve our understanding of mako movements and biology, and will improve international efforts to determine sustainable catch levels.
