Yellow croaker breeding technology

Yellow croaker is commonly called yellow croaker. Big fresh. The head is blunt-cushioned, mouth split, end position, sloping, and the kiss is not prominent. The outermost teeth of the upper jaw are enlarged as canine teeth, and the front teeth are relatively large, but are sparse, and the front center has no teeth. The upper half of body side is purple brown, the lower half is golden yellow, and the luminous particles are orange yellow. The dorsal fins are light yellow-brown, with a caudal fin yellowish-brown and dark brown in color. Their hips, abdomen and pectoral fins are bright yellow, their mouths are white, and their rims are light red. Large yellow croaker and small yellow croaker are similar in shape, the difference is based on: the large yellow croaker dorsal fin origin to the side line between the scales of 8 to 9 columns, while the small yellow croaker is 5 to 6 columns, the large yellow croaker second anal fin spine length is greater than or equal to the eye diameter, and small yellow croaker It is smaller than the eye diameter. The ratio of long tail stalk to tail shank height (3.4-3.7) is greater than that of small yellow croaker (2.7-3.4).
Large yellow croaker was once one of China's important economic fishes. It is a unique endemic species in China. It is widely distributed in the South of the Yellow Sea in the north, through the East China Sea and the Taiwan Strait, and south to the east of Leizhou Peninsula in the South China Sea. The fish is a warm, warm cluster of migratory fishes, and often inhabits the middle and lower reaches of the water within a depth of 60 meters. The reproductive season of the large yellow croaker is in spring and autumn. During the reproductive period, the fishes migrate from the overwintering areas of the open sea to the offshore for reproductive and migrating. After spawning, the juveniles grow up in the sea and disperse the bait. As the temperature of the water falls, some of the fish swim over the warm water of the 60-meter isobath. As a precious economic fish, large yellow croaker has long been favored by consumers. However, due to overfishing, the resources are seriously damaged. After years of research, batch cultivation began in 1990. Commercial fish farming has been continuously expanding since 1992, and production has increased year by year. The breeding provinces started from Fujian and radiated to Zhejiang, Guangdong and Hainan provinces. Breeding methods expand from cage culture to pond culture. The specifications for stocked fish need to be neat and consistent. In the plan to achieve the product specifications of more than 400 grams that year, the size of stocked fish species should be around 100 grams. The bait in the growing stage is generally dominated by frozen upper fish and supplemented with powdered food. The upper fish cut into palatable fish pieces with a knife, which is easy to process and is not easy to lose, or the fish is chopped into meat, mixed into a strong bait-like bait, hand-extruded into pieces of different sizes to feed. Fish oysters have more advantages than fish lumps: They can be mixed with some powdered foods or other baits, as well as essential vitamins and medicines to provide nutrition. During the rearing period, feeding is usually performed every morning and evening. Compared with true oysters, squid, etc., large yellow croaker has a slow feeding and a small waiting point. Therefore, feeding should be slow. It grows fastest during high temperatures. In order to maintain the natural color of commercial fish golden yellow. In the later period of culture, cover the shade on the cage to control the light. The optimal growth water temperature is 22-26°C. Salinity 1.8% to 2.5%, dissolved oxygen 5 ml/l or more, pH 8.0.

Goji Juice is the use of fresh fruit as raw material, processed products. Goji juice can also be subdivided into flesh drinks, fruit pulp, 100% Chinese Wolfberry Juice, Chinese wolfberry drinks and other types, most of them using the beating process of fruit or fruit edible part processed into unfermented but fermentable slurry, or in the concentrated pulp added to the pulp in the loss of natural concentration Water Equivalent to water, made with the original fruit pulp color, flavor and soluble solids content of the product. 100% Chinese wolfberry juice is non-concentrated reduced wolfberry juice, to maximize the retention of the wolfberry fruit nutrients, while eliminating any ingredients and additives, is a green safe, non-added food.
