Movement behavior of swordfish provisions connectivity between the temperate and tropical southwest Pacific Ocean.

Swordfish (Xiphias gladius) are a widely distributed (45°N-45°S) large pelagic fish targeted by fisheries worldwide. Swordfish that occur at high latitudes tend to disproportionately be large adults, so their movements have implications for population dynamics and fisheries management. In the southwest Pacific, little is known about this subset of the stock and existing evidence suggests limited movement from the subtropics into cooler high latitude waters.
