The Patagonia continental shelf located off southeastern South America is bounded offshore by the Malvinas Current, which extends northward from northern Drake Passage (~55° S) to nearly 38° S. The transition between relatively warm-fresh shelf waters and Subantarctic Waters from the western boundary current is characterized by a thermohaline front extending nearly 2500 km. We use satellite derived sea surface temperature, and...

Checks specific for hatchery‐reared fish were present in 100% of recaptured hatchery‐reared mulloway; the origin of which was confirmed by the presence of a chemical mark in the otolith o...
