Southern Bluefin Tuna
Southern Bluefin Tuna are large pelagic fish that migrate long distances in the southern hemisphere between 30 and 50 degrees south. They’re fast swimming and long living fish growing to the age of 35 years old.
Where do they go to breed?
Breeding takes place September to April in warm waters south of Java. The juveniles migrate south down the west coast of Australia.
During the summer months (December – April) they tend to congregate near the surface in the coastal waters off the southern coast of Australia and spend their winters in deeper, temperate oceanic waters. After age 5, they are seldom found in near shore surface waters.
