Albacore reside in the subtropical regions of the North Pacific Ocean, Indian Ocean, North Atlantic Ocean, and Mediterranean Sea. In the North Pacific, albacore are distributed throughout a region from 10 to 50 degrees north latitude, with migration towards the tropical waters during spring and summer spawning months. Albacore occupy similar latitudes in the Atlantic Ocean, but young albacore have been caught by fishermen between 40 to 50 degrees north latitude. In the Indian Ocean, albacore are distributed throughout a region from 50 degrees north latitude to 40 degrees south latitude. In the north, immature albacore occupy 25 to 35 degrees north latitude, mature albacore occupy the north equatorial current region, and spawning albacore occupy the area near 20 degrees north latitude. To the south, mature albacore occupy an area north of 10 degrees south latitude, immature albacore occupy the area south of 30 degrees south latitude, and spawning albacore occupy the area in between (10 to 30 degrees south latitude). Note that for these migratory tuna, April to September are the non-spawning months and October to March are the spawning months in the Indian Ocean, while in the Atlantic, April to September are the spawning months.
