Can sardines be farmed?

Sardines are the genera of sardines, small sardines and quasi-sardines and some edible fishes of the family Herreridae. Sardines also refer to common herring and other small herring or herring made into canned fish in oil. The small ones are two inches long and the larger ones are about two inches long. They are important marine economic fish in the world. Let's take a look at whether sardines can be farmed.

Can sardines be farmed?

Sardines are difficult to raise and are generally not farmed. Sardines are offshore warm water fish, difficult to raise, lazy by nature, often crowded together and motionless, with a high mortality rate. Usually dense group rest, coastal migration, feed on a large number of plankton, mainly lay eggs in spring, eggs and young fish hatched a few days later have been drifting before metamorphosis into free swimming fish, the optimum temperature of most sardines is about 20-30 ℃, only a few species have low temperature, for example, the optimum temperature of far East sardine is 8-19 ℃, and light purse seine, drift Gill net, large pull-net and set net are generally used for fishing.

Are sardines deep-sea fish?

Sardines are deep-sea fish. Sardines usually inhabit the pelagic. Young fish not only feed on planktonic crustacean larvae, but also feed on diatoms and dinoflagellates. Adults live in deep water beyond 70m to 80m in autumn and winter. When the coastal water temperature rises in spring, the fish migrate inshore. The larvae and juveniles grew up along the coast after bait, and gradually migrated northward with the South China Sea warm current in summer, and then migrated southward when the surface water temperature decreased in autumn, and when the fish grew to more than 150 mm after October, it gradually moved to deeper sea areas due to the decrease in coastal water temperature.

Which fish cannot be farmed?

1. Belt fish: belt fish, also known as swordfish and tooth belt fish, are migratory fishes, which are extremely difficult to survive in small ponds or small sea areas, and 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. Small yellow croaker: small yellow croaker, also known as big-eyed, color, cucumber, ancient croaker, yellow croaker, etc., is similar to the big yellow croaker, but the head is longer, the eye is smaller, the scale is larger, and the body length is about 20 cm. It is a group migratory fish at the bottom of the sea and cannot be farmed artificially.

4. Pseudosciaena Crocea: Pseudosciaena Crocea, also known as yellow croaker, king croaker, Daxian, Pseudosciaena Crocea, Golden Dragon, Golden Dragon, etc., are warm offshore cluster migratory fish and cannot be farmed artificially.

5, partial mouth fish, partial mouth fish namely flounder, adult fish lurking in the sea floor life, mostly feed on starfish and other small animals, not suitable for artificial breeding.

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

7. 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.
