Water spaces of our planet inhabit about 20 thousand species of fish. The overwhelming majority of them are marine fish (more than 14.5 thousand species). Anthropogenic effects on the inhabitants of the seas and oceans affects much smaller, so sea fish in sanitary and hygienic criteria is considered much "cleaner" than freshwater.
Description Tuna
Caught in 2012 off the coast of New Zealand, the largest tuna in the world in the world weighed 335 kg.
The life of this kind of skumbrid fish due to anatomical features is impossible without constant movement, to which they are well adapted. Tuna has a spindle-shaped, with massive side muscles, narrowed to the tail body. The tail stem is equipped with a large leathery kelle, the fins are perfect for fast and long swimming sickle shape. Blood is saturated with oxygen, and the body temperature is much warmer water, which allows them to feel comfortable in cold water bodies.
Fish in tropical and subtropical areas of the quiet, Atlantic and Indian oceans is widespread, but it is also found in cooler temperate latitudes: inhabites in black, Japanese, the Azov seas. In the Barents Sea there is a subspecies of the Atlantic Sinepeur Tuna.
Tuns are excellent swimmers capable of developing speed up to 90 km / h. In pursuit of food they are able to quickly overcome huge spaces. Tuns hold big jambs. The red meat is explained by the presence of iron-containing Mioglobin protein, which is actively produced in the muscles at the "high-speed" movement.
The main feed for tuna is the small fish (Sardine, mackerel, herring), crustaceans and mollusks. The ability to reproduce the tuna comes in a three-year-old. A large female is able to postpone several million iconic. Snerest occurs in the warm waters of subtropics in June-July.
Tuna views
There are about 50 species and subspecies, but several of them are considered to be several:
- An ordinary or red tuna is distributed in the equatorial waters of the Atlantic Ocean, in the Caribbean and Mediterranean seas, in the northeastern areas of the Indian Ocean, the Gulf of Mexico. Occasionally meets red tuna and in cooler latitudes: off the coast of Greenland and in the Barents Sea. The largest tuna of this species possessed 684 kg weighing, with a length of 4.58 m.
- Atlantic or black manner (he is the black tuna) is the most small among the tuna. Adult specimens grow no more than one meter and gain maximum weight - 20 kg. The life expectancy of this species is the shortest among the tunts - about 4-6 years. Atlantic tuna has yellowish sides and a back fin with a yellow tide. This species prefers only the warm seas of the Western Atlantic (from the shores of Brazil to Cape Cape Code).
- Blue tuna - the largest view. Maximum length - 4.6 m, weight - 680 kg. Its thick body in the cross section has a circle form. Large scales along the side line resembles a kind of shell. The habitat of the blue tuna is very wide - from tropical, to the polar waters of the world ocean. Blue tuna has the greatest commercial value.
- Yellow-drift tuna (he is a yellow) dwells in tropical and moderate latitudes, with the exception of the Mediterranean Sea. The maximum length is 2.4 m, the maximum weight is 200 kg. Rear fins of these fish have a bright yellow color. Adult yellow tuna tuna on a silver bastard has 20 vertical stripes.
- Albacor, long-term or white tuna is famous for the most gentle and greasy meat. Weighs a long tuna about 20 kg. Widden in moderate and tropical latitudes of the World Ocean. The meat of white tuna is considered the most valuable.
Tuna Zholevostya
This species of fish (they are also called yellowing tuna) is called so due to the special color of the spinal (soft) and the anal fins. They look like orange yellow.
The largest individuals can grow to a 2-meter length and gain weight of 130 kg. The growth process of tuna growth is very intense, the rate of increment is 50 ... 60 cm. For 2 years, the fish reach weights of 13 kg, after 4 years - 60 kg.
Lives a yellow tuna only in warm waters, it is found in all the earth's oceans. The distribution area is limited to the boundary with a 20-degree water temperature. When the indicator decreases to + 18 ° C, this type of fish in such a region is almost impossible. Catch it in the waters of the Mediterranean Sea, and the locals consider it to be their Mediterranean tuna and prepare excellent dishes from it.
Adults are inhabit only in the oceans, on open spaces, at the depths of one and a half hundred meters. Young is held by flocks, constantly closer to the surface and to the shore. In the tropics, the yellow tuna come across everywhere, but their number depends on the state of the feed base. Fish is larger in waters in which heightened biological productivity is observed and a lot of food.
Inside the territory of one area, tuna often form numerous populations that live in certain areas of the oceans. Among them are those that make long migrations. There are others who prefer local waters and awaited life. Yellow-driving tuna do not commit, as their some fellow (syneper tuna, Albacor) Pacific displacements.
A yellow tuna, as well as his relatives, tuna ordinary, unintelligible in food, he does not have any preferences. Four feeds through everywhere by any organisms that are found along the path of movements. This is confirmed by the composition of food residues in the stomachs in caught individuals, in which up to 50 diverse fish belonging to different groups are present.
Small tuna, whose life passes near the surface, hunt more for fish, for which the water layers at the surface are "home". Large prefer to eat gempils, fish lunas, sea bream, whose habitat is medium depths.
The ability to have offspring in yellow-minded or, as they are called among professionals' fishermen, yellow tuna comes only when they are growing in length by 50 ... 60 cm. The number of eggs is different in different parts of individuals. The minimum is approximately 1 million pp, the maximum - 8.5 million hp. The period of orcrew the yellow tunats in the tropics is all seasons of the year, closer to the borders of the habitat in the summer.
Long Tuna
Such fish are also called albackers. It differs from other types of fins located on the chest that they have large sizes.
You can meet individuals from this species in the oceans, on the free of their spaces. The most promising places between fortieth latitudes for this. They are extremely rare to the coastal sections of the reservoirs. Outside the boundaries of the range can only dwell ... 6-year-old fish. And only in the upper layers, if they are sufficiently launching the sun. Pisces transfer only salinity inherent in the waters of the oceans. Confidently temperature fluctuations in the range of + 12 ° C ... + 23 ° C). At the same time, with a small level of salinity, freshwater tuna - the phenomenon is unreal and not occurring anywhere in the world.
In the first years of fish life is in the surface layers of water. When growing to half the rise, "go" 150 ... 200 meter depths and in the tropics of the Earth.
The fish, which "mastered" moderately warm water and lives there, feeds, mainly inhabitants (crustaceans, fish, squid) inhabitants in the layers of water close to the surface of the reservoirs. In the tropics in her food there are deep-water inhabitants (sea leaves, gumpiles, some cephalopod).
Long-term tuna comes up to the period of half a variety of 4 ... 5 years of life. Its condition is characterized by almost a meter (90 cm) long and 45 kg of weight. Spare in the tropics occurs in the spring-summer period, on the boundaries of the zone. The females are postponing to 2.5 million hp ikrine.
Fish is inherent on constant migration, and at considerable distances. For example, in the Pacific Ocean, this is observed between Japan and the shores of America almost in almost one ways.
Today, the long-term tuna is under the protection of the international red book.
Black tune
This type is the smallest among those known. Usually, it does not exceed half a meter and 3 kg of weight. Although the occasionally observed individuals of a meter length and weighing 21 kg.
The habitat of black tuna men is very limited than he dramatically stands out among his fellow. It is found only in the Atlantic, and in its western part. This is a water area in the south of Rio de Janeiro and in the north of Massachusetts. For life, it prefers near-surface places where the water is clean and warm.
The body of fish in the form close to oval. It, together with the tail (has a sick-like profile), allow black tuna to move at a very high speed. The body of the fish on the belly is painted in white, on the sides in silver, the colors of the back can be black, bluish-gray or intermediate by shade. On the sides there is also a band that is blurred borders and golden yellow colors. It is wide in the head of the head and narrow on the tail. The bottom (section of the tail-anal fin) and on top (section of the tail-second dorsal fin) on the body there are small protrusions in size.
This wild tuna becomes haweling faster than all of its relatives - by 2 years. Ikrometania occurs in different habitats in different ways - April-November. Falls appear quickly and immediately begin an independent life. They drift by the will of flow in the thickness of water, about 50-meter depth. Grow fish quickly and by 5 years is considered old.
In the diet of the black tuna foots, the crabs, shrimps, squid, a variety of fish. Because of small sizes, they themselves often become the prey of other fish living in the oceans: striped tuna, big cornflowers, blue marlin.
Black tuna is valued by fishermen and is considered desirable trophy.
Striped tuna
This species (he is Skipjek), in contractions, several longitudinal bands located on the body. They have a silver color on the belly, closer to the back - ash-blue. Fish among tuna, which constantly live in the open ocean, the smallest. It rarely can be caught a meter value and with a weight of 25 kg. "Standard" with catching values \u200b\u200b5 ... 3 kg and 60 ... 50 cm.
Live such tuna only in the near-surface layers of water and only in the ocean. Sometimes it is caught by the shore, but this is possible only near the reefs from corals. Habitat - Pacific Ocean, in its subtropical, tropical areas. Also lives in the seas having warm (+ 17 ° C ... + 28 ° C) water.
Prefers to be in a stagnation, sometimes gathering in the shoals up to a tent of thousands of individuals. In the pack, more often fish of the same age and physical condition capable of moving equally quickly (the speed reaches 45 km / h). In addition to the "clean" there are less frequently mixed in the composition of fish fish (yellow-fed tuna, dolphins).
Like most relatives, striped tuna make seasonal significant migrations. Especially they are noticeable near the shores of Japan. In the summer, there are sometimes accumulations of fish sometimes to the Kuril Islands, south of which, at this time, there is also a tuna largelase, living on a large (over 200 m) depth and reaching 2.36 m long.
The fish become capable of throwing caviar, living 2 ... 3 years, when their body becomes a 40-centimeter length. The fertility of fish is directly connected with the latter. For example, a females of 40 cm long swipe up to 200 thousand hp. Ikrinka, 75 cm - up to 2 million ppm Self places coincide entirely with tuna spreads and are only in the tropics.
It feeds this type of inhabitants of the surface word of water bodies. Their diet usually includes small fish, crustaceans, squid. It includes more than 180 different animals. A specific set will be varied in every place of habitat.
Macrel tuna
Fish of this type are the smallest of those living near the shores. It is an epipelagic fish, lives in the warm tropical seas of the Pacific, Indian, Atlantic Oceans.
The color of the body on the back is dark blue and almost black on the head. Bock bluish with dark wavy stripes. Beluto white. Abdominal and thoracic fins of different colors: black on the inside and purple on the outside. In contrast, the short length of the breast fins and the absence of a swimming bubble.
Grow up to 40 ... 30 cm and dials only 5 ... 2.5 kg of weight. Sometimes there are instances of 58 cm of length.
In the nutrition of these fish includes plankton and small fish (Anchovies, Atherina, etc.). Tuns themselves often become the prey of their major fellow.
Paul ripening occurs when the body length is reached 35 ... 30 cm. Fertility of females of 200 thousand ... 1.4 million eggs, depending on the length of 30 ... 44.2 cm. Rights are spawn year-round: January-April in the Pacific Ocean (Eastern part) ; August-April in the Indian Ocean (southern part).
Mackel tuna tend to extended migrations in the waters of the oceans.
Atlantic tuna
Atlantic tuna from the brightest, rapid and large fish. It is warm-blooded, which is very rare among fish. It lives in the waters of Iceland, the Mexican Bay. It appears in the tropical waters of the Mediterranean, where it comes to spawning. There was an earlier this species in the Black Sea, but at present this population remained in history.
The fish has a streamlined body, which has a torpedo-shaped body, which is ideally aerodynamically and allows the fish quickly and long move. The color of the back on top of blue metallic, belly silver-white, with a shimmering tide.
Nutrition of the Atlantic Tuns: zooplankton, crustaceans, acne, squid. Appetite at the fish is insatiable, so they usually grow into a length of two-meter and gain weight in a quarter of a ton. There are individuals and with more impressive characteristics. For example, it is believed that the largest Atlantic tuna was caught in waters near New Scotia. He "pulled" by 680 kg.
Tuna fishing - Features of fishing in the sea
Most often, flocks are at a small depth, in places of accumulation of small fish. Tuns hunt gambling and noisy, so it is not difficult to detect their presence on boobuns and flying splashes. Often, flocks of tunats accompany dolphins and seabirds.
Usually hunting begins with bait: in the alleged area of \u200b\u200bhis location, it is thrown out fresh or frozen small fish. Tuns are very vividly reacting to small bubbles of water, so fishermen, as bait, are widely used "artificial rain": a special sprayer is installed on the feed of the boat, which waters the sea surface along the movement of the vessel, creating a bubble spot that is confused on it. Nursing fry. Fishermen thump in the "bubble zone" glitter in a plumb 2-3 m and waiting for bite. This method is good only with gladly clear weather.
In other conditions, the lines are carried out by trolling method: the bait (heavy glitter or wobbler with rehabilitation up to 5 m) is transported on a solid cord behind the floating ship. Sea spinning is suitable as a tackle. The dimensions of artificial bait should be rather large and bright - about 18 cm, otherwise it can simply not notice it, because fishing occurs with the boat moving at speeds. Trolling coil and cord should choose strong (with a power of 50 to 130 LB).
Buck is hunting in places of mass distribution. The design of this fishing rod is simple: the basis is a solid rod that is used complete with a special belt. In the belt there is a deepening, in which Kollya rods be resting when the tuna is bought. Durable cord or fishing line tightly attach to the rod. The polished hook (No. 6/0) should be without a beard. Throw it without caution - it works like glossy.
The fishing is enough for the bait confidently and decisively, so you will simply keep it enough, but the retraction of large trophies can delay for a long time: a tuna is a strong and desperate fish, which is capable of a long and violently resist, testing a fisherman and its tackle on strength. Large individuals are removed from the water with the help of bugs and special winches.
