Archival tagging of subadult and adult common thresher sharks (Alopias vulpinus) off the coast of southern California
The common thresher shark (Alopias vulpinus) is a secondary target species of the California drift gillnet fishery (CA-DGN) and supports a growing recreational fishery in California waters. This study used archival tags to examine the movement patterns and habitat preferences of common threshers of the size range captured in the CA-DGN (>120 cm fork length). Depth and temperature-logging archiv...
متن کاملMovement patterns and nursery habitat of juvenile thresher sharks Alopias vulpinus in the Southern California Bight

Seven juvenile threshers were tracked using acoustic telemetry to determine their movement patterns and nursery habitat in the Southern California Bight (SCB). Tracked sharks occupied waters over the continental shelf 87% of the time. These water...

The convergent RM morphology among all species capable of RM endothermy suggests that RM position is a stron...
