Tuna

Australia is home to several species of tuna, including Yellowfin Tuna, Southern Bluefin Tuna, Bigeye Tuna, and Albacore Tuna. These fish are highly migratory and can be found in different regions of Australian waters throughout the year.

Yellowfin Tuna (Thunnus albacares) is a popular game fish and commercial species in Australia. It has a sleek, streamlined body with a metallic blue-black back and silver belly. Yellowfin Tuna can grow up to 2 metres in length and weigh over 200kg. They are typically found in warm waters, and are commonly caught by trolling or by casting lures or baits.

Southern Bluefin Tuna (Thunnus maccoyii) is another important commercial and game fish in Australia. It is a larger species of tuna, with adults often reaching lengths of 2-2.5 metres and weights of up to 200kg. Southern Bluefin Tuna are found in the southern waters of Australia and migrate to warmer waters during the winter months. They are typically caught using purse seine nets or longline fishing methods.

Bigeye Tuna (Thunnus obesus) is a less common species of tuna in Australian waters, but is still an important commercial and game fish. They have a dark metallic blue-black back and silver belly, and can grow up to 2.5 metres in length and weigh up to 200kg. Bigeye Tuna are often found in deeper waters and are commonly caught using longline fishing methods.

Albacore Tuna (Thunnus alalunga) is a smaller species of tuna found in Australian waters. They have a distinctive silver-white belly and can grow up to 1.2 metres in length and weigh up to 30kg. Albacore Tuna are typically caught using trolling methods and are popular for their firm, white flesh.

Tuna fishing is regulated in Australia to ensure sustainable fishing practices. Catch limits, minimum size limits, and fishing seasons apply to commercial and recreational tuna fishing. It is important for anglers and commercial fishers to be familiar with the specific rules and regulations that apply in the area they are fishing.
