Yellowtail seriola quinqueradiata temminck and schlegel Yellowtail subfamily, genus yellowtail, is a warm water fish, distributed in the waters south of the Sea of Japan and Taiwan. Yellowtail range of adaptation to salinity 16 ‰ -34 ‰, the most desirable range of 20 ‰ -25 ‰. Yellowtail on the ability to adapt to high salinity, poor ability to adapt to low salinity, when the salinity below 16 ‰, will die. Water temperature in the range of 20 ℃ -30 ℃, the fish grow quickly, but when the water temperature is below 15 ℃, then stop growing when the water temperature is below 10 ℃, the fish will die. Yellowtail from spring to summer migration from south to north, from autumn to winter migration from north to south. Spawning period in the East China Sea is 2 to 3 months in the waters around Japan, Kyushu and Shikoku islands of 3-5 months. Floating eggs, 1.15 to 1.44 mm in diameter, newly hatched larvae total length 3.5 mm, appeared in large numbers in the water temperature 19 ~ 21 ℃ and chlorine level of 1.91% ~ 1.93% of the waters. Larvae generally drifting northward with the Kuroshio and its tributaries, and concentrated in ocean front area, often attached to drift algae. When yellowtail fish grow to 15 cm, left drifting seaweed, free swimming camp life. 4 cm below the copepods and crustacean Daphnia yellowtail main feeding Philosophy and the like, along with the growth of juvenile fish begin feeding and other small fish. To 15 cm long, then the sardines, mackerel, squid for food. Yellowtail life of 7 years, the maximum individual is 96 cm, weight 13 kg. The main farming yellowtail fish for sea cage culture, generally 1-2 years of farming that should be harvested, then the economic benefits of the best technology currently artificial propagation has been resolved. Yellowtail fish cage culture originated in Japan. In recent years, China Guangdong, Fujian, Zhejiang Province coastal successively conducted several yellowtail fish farming. Breeding period of 2 years, in May put the seed network box, stocking density per square water body stocking 20 kg yellowtail appropriate. With the growth of the mesh netting must be increased in order to 1,1.5,1.7,2.5,4.3 and 6.o centimeters. Yellowtail within 7 ~ 28 ℃ temperature range of survival, optimum growth temperature is 24 ~ 26 ℃. When the density of sea water due to heavy rain fell to 1.015 from 1.025, the growth will be affected. Fed diets once a day. To prevent excessive feeding each week can be stopped bait 1 to 2 days. With the growing amount of food needed per kilogram of body weight also reduced. The first year of breeding, summer food ration to a large, less winter. Second year farming, summer food ration increased to 8% of body weight in winter to 3% to 4% of their body weight. Sandeel fish, sardines, fish and mussel saury as yellowtail fish feed. Feeding bait must be fresh, otherwise bait corruption, fat oxidation, can cause abnormal physiological after yellowtail fish food. Feeding bait fish must be stored at minus 20 ℃. Before use frozen fish feeding, you must first thaw. Small size of the bait fish can be fed whole, the large size of the first cut or chopped and then vote. Feed conversion ratio of about 8. The main diseases of nocardiosis, fake tuberculosis, streptococcus disease. Yellowtail rich dha, namely docosahexaenoic acid. dha human brain nutrition highly unsaturated essential fatty acids. In addition it can prevent the deposition of cholesterol in the blood vessel wall, prevent or reduce atherosclerosis and coronary heart disease, but more important is the dha brain cell has an extremely important role. It accounts for 10% of the human brain fat, nerve conduction and for the growth of synapses is extremely beneficial. Experiments show that, dha intake full, dha value increased human brain can activate brain cells, improve brain function, improve the ability to judge. Undoubtedly, dha has a very significant role in brain puzzle is to enhance the intellectual youth, enhance memory, improve learning ability required nutrition. Yellowtail known as "nourish the brain Kamijina" reputation. The scientists showed that, dha exist only in a small number of fish and shellfish, and other foods such as soybeans, butter, vegetable oil, lard, vegetable and fruit almost never contain dha. Therefore, from the perspective of nutrition and brain, people want to get enough dha, the most simple and effective way is to eat yellowtail ideal.

Yellowtail Seriola Quinqueradiata Temminck and Schlegel Chaoshan Common name: Oil Gan. Yellowtail subfamily, genus yellowtail, is a warm water fish, distributed in the waters south of the Sea of Japan and Taiwan.

The main diseases of nocardiosis, fake tuberculosis, streptococcus disease. Yellowtail fish rich in DHA, docosahexaenoic acid that. DHA is an essential nutrient in the human brain highly unsaturated fatty acids. In addition it can prevent the deposition of cholesterol in the blood vessel wall, prevent or reduce atherosclerosis and coronary heart disease, but more important is the DHA for brain cell has an extremely important role. It accounts for 10% of the human brain fat, nerve conduction and for the growth of synapses is extremely beneficial. Experiments show, DHA intake sufficient, DHA increased the value of the human brain, you can activate brain cells, improve brain function, improve the ability to judge. Undoubtedly, DHA has a very significant role in brain puzzle is to enhance the intellectual youth, enhance memory, improve learning ability required nutrition. Yellowtail known as "nourish the brain Kamijina" reputation. The scientists showed, DHA exists only in a small number of fish and shellfish, and other foods such as soybeans, butter, vegetable oil, lard, vegetable and fruit almost never contain DHA. Therefore, from the perspective of nutrition and brain, people want to get enough DHA, the most simple and effective way is to eat yellowtail ideal. Yellowtail, along with a growing, changing the name, the price is rising fish. The fish in Japan more than 100 names. Japanese Yellowtail famous origin is facing the Sea of Japan Toyama Bay. As of yellowtail fish back, was born in the southern tip of Kyushu, warm waters, swim in droves to the southern waters of Hokkaido, and then swim back to southern waters in autumn when the temperature drops. The second winter, grow into one meter in length and weighing 10 kg of adult fish spawning south. Yellowtail fishing at this time called "cold yellowtail," is the most delicious. Japanese yellowtail farmed fish are generally kept (about 4 kg) called hamaqi, to distinguish them from natural yellowtail. In Japan the country, yellowtail and salmon as par auspicious New Year's Eve ate fish and famous. In central Japan runs a large trench belt is bounded by the fish like salmon Circle into western and eastern yellowtail cultural circle. In the Kansai region of Japan, yellowtail fish species indispensable first month. Especially in the Hokuriku region, the first month or day of celebration on the table if the lack of yellowtail fish, then this family hospitality specification becomes a problem. Thus, Yellowtail occupies what position in the Japanese daily life.
