Fine cultivation method of barbus capito

Abstract

The invention discloses a cultivation method of a barbus capito, which comprises the following steps of: A, establishing a fry culture pond, a fry screening pond positioned below the fry culture pondand a large fish culture pond positioned behind the fry culture pond, wherein the height of the large fish culture pond is lower than that of the fry culture pond; B, putting fries of 2-3cm in size into the fry culture pond for fry culture, when the fries grow to 9-10cm, enabling the fries which do not reach the specification to fall into the fry screening pond, and enabling the fries which meet the specification to enter the large fish culture pond; C, taking out the fries which fall into the fry screening pool, putting the fries into the fry culture pool again for continuous culture, carrying out large fish culture on the fries which enter the large fish culture pool; D, finishing seedling culture when the fries grow to 15cm. The method has the advantages that the fries can be classifiedand screened, so that the controllability is improved, the growth speed is improved, the high survival rate is ensured, the purpose of fine management is achieved, the yield and the quality are ensured, and the investment cost is reduced.

Description

technical field [0001] The invention relates to a method for cultivating large barb, in particular to a method for cultivating large barb. Background technique [0002] The giant barb belongs to the family Cyprinidae, the subfamily Cyprinidae, and the genus Barp. It is a euthermic fish with delicious meat, fast growth, strong stress resistance, and salt-alkali tolerance. It has excellent properties such as wide appetite, fast growth, delicious meat, salt and alkali resistance, and strong adaptability. It is more cold-resistant than Chinese barbed barb, light spiny barb, black scale barb, and money barb, which enriches the cultured species of barb in northern my country. [0003] However, after the introduction of the large barb fish species in my country, the existing seed culture is usually directly through the outer pond when the fry are 2-3cm. Careful management of specific growth conditions leads to uncontrollable yield, low survival rate and high input costs, especial...

Problems solved by technology

[0003] However, after the introduction of the large barb fish species in my country, the existing seed culture is usually directly through the outer pond when the fry are 2-3cm. The specific growth conditions are carefully managed, resulting in uncontrollable yield, low survival rate and high input costs, especially the unreasonable use of feeding feed and inappropriate feeding methods, which are not conducive to its rapid growth
