The primary diet of albacore includes pacific saury, northern anchovy, crustacean zooplankton, gonatid squid, and Japanese anchovy. Albacore are opportunistic piscivores and their diet varies seasonally depending on location. Anchovy typically constitutes up to 96% of the stomach contents of albacore at any given time. Some studied fish fed on other schools of fish when encountered due to the patchy distribution of anchovy, demonstrating the opportunistic feeding habits of albacore. Albacore also exhibit a diel vertical migration pattern, following their prey throughout the water column.
