New publication reveals the 2-year migration for adult female white sharks in the northeastern Pacific

all

MCSI has published a new scientific paper that reveals the multi-year migratory patterns of four tagged female white sharks Amy, Kimel, Annika and Tailscratch. These sharks spent about 15 months in the middle of the Pacific ocean before traveling to the coast of Baja Mexico during the known pupping season. Amy and Kimel traveled into the Sea of Cortez while Annika and Tailscratch went to the Pacific coast of Baja.

MCSI develops new methods for tagging adult white sharks

_DSC1684b

Scientists at MCSI have been working to improve methods for SPOT tagging adult great white sharks. New methods developed, tested and implemented by MCSI involve a device to prevent gut hooking, soft fishing gear to prevent skin abrasions and constant forward movement to fully irrigate the gills. Sharks tagged in this manner, including the largest white shark to ever be SPOT tagged, were far more vigorous upon release than our previous method that lifted the sharks from the water. We strive to constantly improve our methods to do what is best for the sharks and the scientific community.
