Description
The tuna is like mackerel or the bonito, a family member of the scombroid-fish.
It has a spindle-shaped body. It has false fins (sights) are behind 2nd dorsal fin and anal fin. Its long pectoral fins extend to the 2nd dorsal fin. In long fin tuna, the pectoral fins exceed the beginning of the dorsal second.
The long fin tuna is smaller than blue fin tuna (see above). In blue fin tuna, the caudal stalk supports 8 or 9 sights (7 or 8 in long fin tuna also said Germon). The dorsal fins are close one to the other. This fish is deprived of tasks and/or scratches).
Implantation
The blue fin tuna as well as long fin tuna have with little thing close the same surface of distribution. It is in the form of a broad band any goshawks of planet. It goes for blue fin tuna of the north of British Isles until the south of Morocco, the south of Alaska up to the level of the Central America and passes to the north of Australia.
For long fin tuna, the tape is broader since it goes from the north of British Isles until the south of Africa, of North America in and sea South America of Japan until the south of Australia.

Lifestyle
The long fin tuna (Albacore) is a gregarious fish which lives in the roadbase of the seas and oceans. He water whose temperature lies between 15 and 20 degrees. This tuna its sexual maturity towards the age of 4 or 5 years.
|
After having cleared, the population of the Albacores of the North Atlantic migrates towards Iceland where it will find in abundance the and the cephalopods of which it is nourished. The blue fin tuna is a fish oceanic (which approaches the coasts sometimes), gregarious, migrating and pelagic. It supports the wide variations of temperature and this moves in made up test rigs similar individuals of sizes. The eggs which measure around a millimetre, float meadows of surface until the blossoming which intervenes 2 or 3 days after the laying. The growth is particularly fast since with the 3 years age, the blue fin tuna reaches the size of the meter. After the period of the abrasion, this fish starts a long migration towards the north (Scotland, Norway, sea of ) where It abundantly nourishes alevins, herrings and mackerels.
Fish
of blue fin tuna makes that the large specimens are increasingly rare.
Fish with lines trailed at high speed (Golf of ). The blue fin tuna is fished with the floating net, with the trailing and dormant line.
For long fin tuna (Albacore), you can use like Sardine or mackerel with strong iron hooks of size 2/0 with 6/O. If you identified a test rig of small fish, it is possible that this tuna then comes to nourish itself.
