Juvenile Albacore Tuna (Thunnus alalunga) Foraging Ecology Varies With Environmental Conditions in the California Current Large Marine Ecosystem.
Characterizing changes in albacore diet with changing environmental conditions is key to understanding variability in albacore abundance, distribution and availability to recreational and commercial fisheries. ARF has been keenly interested in changes in albacore foraging characteristics and has actively supported diet studies through the collection of stomach contents and associated data necessary to carry out these studies.
*Juvenile North Pacific Albacore refer to fish of 1 to 5 years of age that have entered the surface fishery but have not yet returned to the western Pacific to spawn. These are the fish that are sustainably harvested by ARF member vessels using troll gear.
Dynamic Habitat Use of Albacore and Their Primary Prey Species in the California Current System
Juvenile north Pacific albacore (Thunnus alalunga) forage in the California Current System (CCS), supporting fisheries between Baja California and British Columbia. Within the CCS, their distribution, abundance, and foraging behaviors are strongly variable interannually. Here, we use catch logbook data and trawl survey records to investigate how juvenile albacore in the CCS use their oceanographic environment, and how their distributions overlap with the habitats of four key forage species.
