Artificial Breeding Method of Broadfin Carp

Abstract

The invention discloses an artificial breeding method of zacco platypus. The artificial breeding method includes following steps: S1, building a breeding area; S2, stocking fries; S3, breeding juvenile fishes; S4, breeding sub-adult fishes; S5, breeding adult fishes. Through the artificial breeding method, dissolved oxygen, water temperature, feeding and water changing of a zacco platypus breedingarea at each breeding stage are controlled, artificial breeding of zacco platypus is realized, and zacco platypus breeding survival rate is high; the artificial breeding method is suitable for large-scale breeding of zacco platypus.

[0002] Broad-finned carp, belonging to Cyprinidae, Cyprinidae, genus Carinae, commonly known as Xige, Peach Blossom Fish, Double-tailed Fish, Red Chegong, Red Winged Fish, White Glutinous Fish, Red Hanging Edge, Red Wings, etc., is widely distributed. It is distributed in China, North Korea, and Japan. In China, it is distributed in Heilongjiang, Yellow River, Yangtze River, Pearl River, Lancang River, and various streams along the eastern coast. It is especially common in mountain streams. It is a typical small stream fish, mostly inhabiting clear mountain streams and river tributaries. The general individual is about 14 cm long, the largest individual can be as long as 20 cm, and the general individual weighs 25 grams. The body is long and flattened, with a round abdomen. The head is short, the snou...
