FISH FACTS: Bluefin Tuna

Posted by devo on Thu, Jan 28, 2010 in Blog

Tuna is a staple of any sushi restaurant and we have many choices that feature this fantastic fish. Including Spicy Tuna, Chilli Rolls, Sticky Balls and many more. The texture is almost creamy and there is no “fishy” aftertaste. Pure heaven with the right cut.

Fish Facts:

The Bluefin tuna are among the top ocean predators.  These powerful, warm-blooded fish can grow up to 10′ long and weigh 1,500 pounds. The tuna possesses a streamlined body to reduce water resistance and conserve energy for trans-Pacific migrations. Retractable fins also allow a freer flow of water when navigational changes do not require their use.

Most fish are cold-blooded (ectothermic). However, all tunas and the mackerel sharks are warm-blooded, in the sense that they can regulate their body temperature.

Bluefin tuna mature slowly, reaching sexual maturity at about 5 years of age, with a maximum lifespan believed to be about 25 years. They reach up to 4.5 ft in length and can weigh 450 lb. They eat smaller fish, krill, pelagic red crab, and squid.

Pacific Bluefin Tuna are overfished throughout the world.  They are hooked on long lines or illegally netted where they swim, and many young bluefins are captured before they reproduce. Creating effective fishing policies for bluefin tuna is difficult because they are highly mobile and swim through the territorial waters of many different nations. Data about their movements and high levels of international cooperation are needed to ensure sustainable bluefin tuna populations.
