Yellowfin Tuna

In Tuna

Yellowfin or yellowfin tuna is one of the largest tuna species in the world, and can tip the scales by more than 300 pounds, although its overall size will depend on where they live and the food resources they are able to rely on. They are lovely fish, and people often enjoy observing their colors and graceful movements in the water.

State of conservation: almost threatened.

Description. The body of the yellowfin tuna is shaped like a torpedo, making it very fast fish. This gives them the ability not only to move at a higher speed, but also to do so for long periods of time. They have a yellow color in various places on their body, they also have very nice blue colors, which help them to mix well with their environment.

Distribution. You will find yellowfin tuna in the shallow areas of the oceans, however, they move to deeper areas during the day and then return to the shallow areas at night. In general, they will remain in the upper 100 meters of water, where they are able to obtain their food resources.

Most of these fish are found in the Indian Ocean, and the Hawaiian Islands are a popular tourist attraction in these areas due to their size, design, and colorful bodies. The fact that they usually remain in shallow water makes them easy to see. They are also very common throughout the Caribbean Sea and the Maldives.

Behavior. Yellowfin tuna is very loyal to your school or group, and will do everything possible to protect others. Usually, they look for food on top of the water, but when they do not find it they will adapt. They can create diving equipment to deep areas of the ocean and then push their prey to the surface. They are often seen around other forms of aquatic life, which include dolphins and whales. They usually do not interact much, but they seem to be able to survive in the same space without any problem.

Feeding. Yellowfin tuna feed on a wide variety of fish found near the coast and around the surface of the water. They have a great appetite and will consume as much food as they can, eat even when they are completely full which can prevent them from moving full, they will resume their normal speed after having digested part of the intake.

Reproduction. Spawning can occur at different times of the year, depending on its location. Yellowfin tuna can travel long distances to mate. They are ready for mating when they are 2 to 3 years old.

A female can release up to 10 million eggs per season, however, only a small fraction of these eggs will be able to survive until adulthood, and young people are often consumed by a variety of predators. The bigger a tuna is, the better chance it has to survive. They have a life expectancy of around 8 years.

Conservation. Although the total population of yellowfin tuna is not extremely low, there are some concerns. The issue of commercial fishing has caused a drop in their numbers. Sometimes, they are not the intended target, but they end up in nets to catch other fish, such as blue marlin.
