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. Careful management of specific growth conditions, resulting in uncontrollable yields, low survival rates and high input costs

Embodiment 1

[0021] The method for industrialized cultivation of giant barb seedlings of the present invention comprises the following steps:

[0022] A. Fry delivery

[0023] Put 2cm fish fry in a cement pool with a side length of 9m and a water depth of 1 meter. The middle and bottom of the pool are respectively equipped with 2mm filter screens for sewage collection. Nano-aeration tubes are distributed around the cement pool, and the dissolved oxygen is 3mg. / L, ammonia nitrogen value is less than 0.3 mg / L, nitrite is less than 0.5 mg / L, pH value is 7.5, water temperature is 18°C, 45,000 tails per pool;

[0024] B. Fry feeding

[0025] The microcapsule feed with a particle size of 0.6 mm is used for feeding. The protein content of the microcapsule feed is 45%. When feeding, feed in batches. When feeding, feed once every 2 hours, and the amount of feeding is 1.5 Kg / day;

Abstract

The invention discloses an industrialized culturing method for barbus capito offspring seeds. The industrialized culturing method includes the steps of A, putting in barbus capito fries: putting the barbus capito fries which are 2-3cm in size into a cement pond; B, adopting microencapsulated feed to feed the barbus capito fries, and feeding in several times; C, separating the barbus capito fries in different ponds: when the barbus capito fries grow to 9-10cm in size, putting half of the total barbus capito fries into a new cement pond which is as same as the used pond in specifications and water quality; D, feeding the barbus capito fries in different ponds: after the barbus capito fries are separated, selecting the feed 1-2mm in grain size, and feeding in several times; E, when the barbus capito fries grow to 15cm in size, finishing culturing. The industrialized culturing method for the barbus capito offspring seeds has the advantages that corresponding feeding conditions can be provided for the barbus capito fries according to specific growing conditions in different stages of the barbus capito fries, quick growing of the barbus capito fries is guaranteed, the purpose for refined management is realized, survival rate can be increased, controllability of output can be guaranteed, and investment cost can be reduced.

Description

technical field [0001] The invention relates to a method for cultivating large scale barb, in particular to a method for industrialized cultivation of large scale barp seedlings. 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. Native to the Amu Darya River in Uzbekistan. 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 my country's current artificial culture of Chinese barbed barb, light spiny barb, black scale barb, and money barb, and 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. S...
