Ahi (Thunnus albacares)

The Ahi fish or Thunnus albacares is often called the Yellowfin Tuna. This species of Tuna grows to about 94" (239cm) and can weigh as much as 440lbs (200kg)! As you can imagine these impressive sizes make the Ahi a favorite tr ophy fish among fisherman. Once these saltwater monster are caught they are quite delicious as well.

These fish's dorsal fin and anal fin are a bright yellow which gives them their name the Yellowfin Tuna. The rest of their bodies are a blue color that turns to a silver on their bottom halfs. Due to recent overfishing and illegal fishing the numbers of these beautiful fish have dramatically dropped off. Like many of the fish in our oceans this species is now considered an endangered species.

Yellowfin Tuna can be caught by trolling with lures or just fishing with live bait while drifting. If using live bait, Pilchards, Mackerel, Redfish and Skipjack Tuna. You can check out the Ahi underwater in the video below.

Albacore (Thunnus alalunga)

The Albacore fish or Thunnus alalunga is a form of Tuna that has become extremely popular over the past couple of decades. These tasty fish can grow up to 140 cm (55 inches) and weight in at up to 60 kg (132 lbs)! One notable characteristic of the Albacore is that its pectoral fins are as much as 30% of the total length. Like the other kinds of Tuna the Albacore is considered to be a great fish to catch with its powerful swimming and jumping abilities.

Albacore are very low in sodium and are a very good source of protein, vitamin A, vitamin B12, selenium, and niacin. The bad part about Albacore is that has more mercury than canned light tuna. In fact, the FDA even recommends limiting the amount of consummation for woman and children. This is just another example of how the pollution we give off is effecting our ecosystem.

The Northern Bluefin Tuna or (Thunnus thynnus) is was one of the most popular forms of tuna. Recent overfishing though has pushed this fish to the brink of extinction. This fish is often used when making sushi, not normally the kind you would find in canned tuna. The Northern Bluefin Tuna can live for about 30 years, but rarely gets to that age due to commercial fishing. Often found in schools these fish are considered to be very easy to catch.

The largest recorded Northern Bluefin Tuna was 4.3 m (14 ft) and weighed a massive 680 kg (1,496 lb)! That is one big Tunafish! One thing that sets this fish apart from other is their unique circulatory system. Northern Bluefin Tuna have some of the highest amount of hemoglobin per unit of blood among fish. Also known as Atlantic Bluefin these fish are homeothermic ("warm-blooded") and are therefore able to thermoregulate. This process keeps their body temperatures higher than the surrounding water, which is why they are able to survive in colder waters. This salt water fish is a carnivore that hunts sardines, herring, mackerel, squid and crustaceans.
