“Seriola quinqueradiata” is a sea predator that is highly valued by residents of the Country of the Rising Sun. They do predator known as “Buri” or “Hamachi”. The average individuals rather impressive: length not less than half a meter, and weighs about 40 kg. In fact, modern experts share deltahotel and Laker. They believe that lacedra and jestokosti is a completely different species of fish. Jestokosti are not such impressive size, as the grow in length up to 1 meter not more, weighs no more than 10.5 kg. in addition, deltahotel wider forehead, like pink, and the mouth is noticeably shifted downward. As for lacery, her mouth is in the middle. While the forehead is not so big. These factors are caused by features of the diet.
It is important to know! Experts say that yellowtail is growing much more actively, compared with the yellowtail. They believe that this fish should be called Golden, but not yellowtail.
Fish of the genus “Seriola” is an elongated, torpedo-like body, slightly compressed from sides. Surface of body covered with small scales on lateral line, one can count about two hundred scales, while on the side-lines are missing flaps. Closer to the tail you can see a kind of leathery keel. The head has a pointed, cone.
The first dorsal fin of yellowtail consists of 5 or 6 short, but spiny rays connected by a strong membrane. The front of the dorsal fin located barb facing in a forward direction.

From snout to the beginning of the tail is broad and conspicuous stripe of yellow. The strip passes through the fish’s eye.
Lifestyle yellowtail of lakedra resembles the livelihoods of mullets. This genus is distinguished by the fact that quickly and can move rapidly in the water column, due to the torpedo-shaped body. The presence of a swim bladder allows the fish feel at different horizons.
Producing natural Northern migration, the fish often moves near the shoals of sardines, anchovies and mackerels, which are the main diet of this predator. With the onset of cold weather, which is typical for the fall, adults of yellowtail lakedra moved closer to the southern areas where they overwinter each year.
Yellowtail yellowtail is different from the fact that jestokosti in the summer, which lasts from July to October migrate from warmer waters to the cold waters, it can reach Sakhalin and Primorye. During this period, jestokosti actively feed nagoeva nutrients.
How many lives yellowtail
Like members of the family “Jacks” do not differ longevity. The average life expectancy of a sort of “Seriola” is about 12 years old.
Members of the genus “Seriola” mainly inhabit the waters of the Central and Western Pacific areas. It is believed that the yellowtail is representative of the offshore areas of Eastern Asia, and jestokosti are representatives of water bordering Korea and Japan. With the onset of summer adults of lakedra begin to appear in the waters bordering Russia. In this regard, this species is found in Primorsky Krai and Sakhalin’s shores. Significant populations of this valuable fish common in coastal waters bordering the Taiwan and down to the Southern Kuriles.
The main diet of adults of deltahotel is fish, so this species is considered predatory. Even individuals who have not attained the periods of puberty, they feed on small fish and zooplankton. Hunt jestokosti flocks, collecting the fish in the so-called “pot”. This diet includes such species of fish:
- Toothy herring.
- Wolf herring.
When fish are grown in artificial conditions, it fed beef, which is based on low-value fish species. Often used a special feed based on fish meal. It is believed that even this diet is scarce, so the meat of these fish is less healthy and tasty. Despite this, the fish grown in artificial conditions, are not less valuable on the world market.
An important fact! When hunting yellowtail, then randomly jump out of the water anchovies, herring or sardines. The water itself like boils, resembling in appearance a boiling cauldron.
Reproduction and offspring
These fish reach an age where they are ready to lay eggs, one and a half years of life. The process of reproduction has certain characteristics. Typically, the process takes a long period of time and extended over several months. This heat-loving fish species, so the spawning is done exclusively in the warm season, when temperature conditions are optimal, that allows time to be born fry.
After birth, the fry begin to settle in the water column that is associated with the characteristics of the species. The younger individuals feed on zooplankton first and then begin to prey on the fry of anchovies, horse mackerel, herring, etc. In appearance the fry of yellowtail lakedra are mirror images of the adults, but in miniature. Regardless of whether artificial habitat or natural, fry lakedra grow and develop quite quickly.
When individuals are grown in an artificial environment, then by year fails to obtain a significant increase in body weight, which allows to make a profit. Individuals who grow and develop in a natural environment, are considered captured only after 2 years of life, and even more. Thermophilic yellowtail yellowtail are so popular in Japan that give its mystical properties. It has long been believed that this fish can bring a person luck.
It is interesting to know! Artificial fish breeding is due to the fact that fingerlings are graded by age and seated in separate cages, made of nylon or nylon. This prevents the likelihood of an attack more adults fry on the weaker. In addition, it is easier to solve problems with the lack of oxygen.
Yellowtail amberjack although it is a predatory fish, have a sufficient number of natural enemies that are able to swim quickly to catch yellowtail. Nevertheless, the main enemy (and no wonder) is the person who catches the fish at a tremendous pace. This is due primarily to its unique taste.
