Can yellow croaker be cultured artificially?

Yellow croaker is a general name of about 160 species of perch-shaped stone head fishes, generally benthic carnivorous fishes, mostly distributed in warm seas or tropical coasts, a few living in temperate or freshwater waters, rich in nutrition, rich in protein, trace elements and vitamins, with the effect of promoting the five internal organs, fitness and beauty, let's take a look at whether yellow croaker can be cultured artificially.

Can yellow croaker be cultured artificially?

Yellow croaker can be cultured artificially. After years of research, Pseudosciaena Crocea began to breed in batches in 1990. the scale of commercial fish culture has been expanding since 1992, and the yield has increased year by year. The province of culture starts from Fujian and radiates to Zhejiang, Guangdong, Hainan and other provinces. The mode of culture has been expanded from cage culture to pond culture.

How to cultivate yellow croaker

The specifications of the fish released by the yellow croaker are neat and consistent. For those who plan to reach the commodity specification of more than 400 grams that year, the size of the released fish should be about 100 grams. The bait in the cultivation stage is generally frozen upper layer fish, supplemented by powdered bait. During the period of cultivation, the bait is usually given once in the morning and once in the evening. Compared with true sea bream and jealous fish, large yellow croaker has slow feeding and less waiting point, so it should be fed slowly and grow fastest during high temperature. in order to maintain the natural golden body color of commercial fish, shade should be added to the cage in the later stage of culture to control light, with the best growth water temperature of 22 ℃, salinity 1.8% and 2.5%, dissolved oxygen more than 5 ml / L, pH8.0.

Marine fish that cannot be farmed

1. Belt fish: belt fish, also known as swordfish, tooth belt fish, etc., belong to migratory fish, and it is extremely difficult to survive in small ponds or small sea areas. belt fish cannot be produced smoothly without migration, so there is no artificial culture of belt fish, mainly offshore fishing.

2. Spanish mackerel: Spanish mackerel is also called mackerel, bony steel fish, and there are many species. There are many species in the Yellow Sea and Bohai Sea of China. They are warm pelagic fish, feed on small pelagic fish and migrate in groups in summer and autumn. They also belong to migratory fish and cannot be farmed artificially.

3, partial mouth fish: the partial mouth fish is the flounder, the adult fish lurks in the seafloor life, mostly takes the starfish and other small animals as the food, should not breed artificially.

4. Pomfret: Pomfret, also known as flat fish, is a kind of migratory fish, which is difficult to breed artificially.

5. Sardines: sardines, also known as sardines, are offshore warm water fishes and belong to a kind of cluster migratory fish, which is extremely difficult to breed artificially.
