Bigeye Tuna
Bigeye Tuna are generally colored mostly dark blue on the upper area of their main body, then silvery-blue underneath, with the midsection and lower body color being mostly silvery-white to shiny silver colored, and as their name implies they have a large round eyes.
Bigeye Tuna can put up quite a battle when hooked, so they are a nice sports fish that numerous anglers love to catch. Their meat is very oily, in fact is probably the most oily or fatty of all the tuna species, but the taste is very mild and pleasant, making it a very tasty tuna for fishermen, restaurants and consumers to enjoy.
Bigeye Tuna have as stated earlier, a lot more fat then other species of tuna, this fat acts like insulation and it allows them to travel down to deeper depths that are quite cold, where other tuna species will not venture. During the night or on very cloudy days, they will come close to the surface, but during bright sunlight they will often be much deeper.
When Bigeye Tuna are close to the surface, they can often be found near objects that are floating or submerged just below the water line, such as bridge pilings, wood, stationary buoys and moored buoys.
When they are young, Bigeye Tuna tend to travel in schools, but the more they mature, the more they travel alone, and it's not uncommon for large adults to spend their last years completely solitary, they can live to be almost 10 years old.
When fishing for Bigeye Tuna using bait, the most effective way is by trolling for them with a boat, since you need to get out to the depths and at areas where they tend to hang out. Some of the most popular baits are; squid, mullet, anchovies and mackerel, and it doesn't seem to really matter if the bait is alive or dead, as the Bigeye Tuna will take it either way.
When fishing during the daylight hours you may have to let the bait go down a lot deeper then, when fishing towards evening, cloudy days or at night.
