They are unique among tuna in that their primary food source is cephalopods, with fish making up a much smaller portion of their diet.
Breeding
Breeding of the Albacore fish generally occurs from November to February, and is oviparous.
Generally a mature female with about 20 kg body weight, can produce between 2 and 3 million eggs per spawning.
Their eggs fertilize outside the female’s body. And the eggs generally take 1-2 days for hatching.
Uses
The Albacore fish is a very popular food fish. It is highly appreciated in the market.
And it is generally marketed fresh, frozen, canned or smoked. It is eaten broiled, fried, steamed and microwaved.
Special Notes
The Albacore fish is very important in many commercial fisheries throughout the world. It is managed throughout most of it’s range. These fish have been found inhabiting depths of 0-600 meters.
And the large fish of up to 21 kg, generally inhabit at depths from 0 to 450 meters with a maximum abundance between 250 and 300 meters. This water depth (250-300m) has a water temperature of 25-15 °C.
The Albacore fish grow very fast. The juveniles remain close to the place where they hatched for the first year of their lives. And they begin to migrate after their first year.
On an average, the fish generally reach maturity at around 5-6 years. And their average lifespan is about 11-12 years. However, review full breed profile of the Albacore fish in the table below.
