First, the artificial fry has strong adaptability.

The artificial loach fry grows in the artificially designed breeding place from the day of hatching, and has strong adaptability; The wild loach, however, is wild and unconstrained, and it is difficult to adapt to the fixed narrow space of the farm.

second, artificial seedlings eat fast.

The artificial seedlings begin to eat artificially cultivated feed from the moment they hatch, so they eat quickly and are easy to absorb. However, the wild fry, accustomed to all kinds of omnivores and suddenly eating artificial feed, need a long adaptation process. When they adapt, they have actually missed the golden time of loach growth.

Third, artificial seedlings are not easy to get sick.

Artificial fingerlings have little contact with the outside world, and grow in artificially sterilized pond water, so the probability of getting sick is very small, while wild fingerlings grow in the wild, so there are many uncertain factors. Maybe some loaches carry pathogens originally, which lays a hidden danger for the large-scale death when they are raised artificially in the future.

Fourth, the survival rate of artificial seedlings is high.

generally, the survival rate of cultured loach larvae is about 8%, the good ones are about 9%, and the highest ones are about 95%. The survival rate of wild loach fry is generally 4%-6%, and the highest is only 8%.
