MEANING BEHIND FISHING IN THE DARK FREE
Skipjack tuna travel in both free schools and schools associated with floating objects, they are the principal tuna species associated with FADs which are often caught alongside juvenile yellowfin and bigeye tuna. This means that even if a skipjack tuna is caught at a young age, the Skipjack has probably already spawned at least once in its lifetime. Skipjack tuna are an abundant species of Tuna because of their short life cycles, they produce early on (at about one year old). Their habitat is located in the tropical areas of the Atlantic, Indian, Pacific Oceans, or equatorial waters. Skipjack tuna are the smallest fish out of the commercial tuna species, their size ranges from 40-80 cm and they weigh around 2.5kg. Skipjack tuna are dark blue/purple cigar-shaped fish with a pointed snout. They provide a firm, fattier meat with a lot of flavors. Bigeye Tuna Fish:īigeye Tuna are large and stout fish and range from 40-180 cm and 1.4-130 kg, residing in tropical and subtropical areas of the Atlantic ocean (not the Mediterranean) and Indian and Pacific Oceans. Albacore tuna are extremely popular in American supermarkets and are often served in larger chunks than skipjack tuna, with a more delicate and drier flavor but a meaty texture. One concern is their high levels of mercury- the Environmental Defense Fund suggests a limited intake of White Tuna. Albacore tuna tend to travel in single-species schools, without mixing with other species and situate themselves in temperate and tropical waters about 400m deep.Īlbacore tuna range from 40-100 cm and 4.5-11 kg. Albacore Tuna:Īlbacore Tuna have the lightest flesh and are the mildest in flavor. The following five major tuna species are only a few of many Tuna species, and each varies in taste, meat texture, color, and accessibility. Widespread thermoregulation indicates why different species of Tuna live in varying water temperatures throughout the world. This causes water to pass through their gills and their muscular metabolism to generate heat. Tuna also regulate their body temperature by constantly swimming to oxygenate their blood. This means sharks that are obligate ram ventilators must constantly swim to survive. Some of the biggest most intimidating sharks are obligate ram ventilators and would actually die from the lack of oxygen if they ever were to stop swimming.
The sharks that use ram ventilation have lost the proper anatomy for ram ventilation or ventilating their gills by swimming quickly with their mouths open. Many prominent shark species swim quickly with their mouths open to ventilate their gills. The next top obligate ram ventilators are none other than sharks. Yellowfin tuna fish are not the only well-known sea creature who are obligate ram ventilators. Specifically, many types of Tuna are obligate ram ventilators due to their uncommon respiratory systems. Some Tuna species overlap with distinct qualities. Within the Thunnini tribe, there are 15 species, most of which fall under the genus Thunnus, and others fall in the genus Katsuwonus, which include blackfin tuna and bullet tuna. Tuna fish belong to the Thunnini tribe which is a subgroup of the Mackerel family, or Scombridae. Tuna are a group of fish (or technically a tribe of fish, Thunnini, within the Scombridae family) that contain over a dozen kinds of fish within that group- tuna are actually not a singular species.
