High-density barbus capito breeding method

Abstract

The invention discloses a high-density barbus capito breeding method which comprises the following steps: A, selecting fries; B, selecting a breeding trough which is 20-22m long, 4-6m wide and 1.3-1.7m deep, placing an aeration pump for aerating the breeding trough on one side of the breeding trough, placing a fish baffle net at the top end of the breeding trough, forming a water inlet in one side of the breeding trough in a width direction, and forming a sewage hole in another side of the breeding trough; C, putting 22-27 fish fries into every cubic meter of a water body; D, performing breeding management, controlling the water temperature of the breeding trough to be 20-28 DEG C and the dissolved oxygen to be 3-5mg / L, supplying protein feed three times a day, and performing sampling detection to confirm the weights of fishes in different periods, wherein the feed accounts for 3-5% of the total weight of the fishes every day; and E, harvesting fishes. By adopting the method, water has good flowability in the breeding process, growth of barbus capito is met, sewage is conveniently discharged, reasonable density is beneficial to rapid growth of the barbus capito, particularly through sampling detection, optimal feeding conditions are made to meet growth demands of the barbus capito in different periods, and thus the yield is further increased.

Description

technical field [0001] The invention relates to a method for cultivating large scale carp, in particular to a method for cultivating large scale carp with high density. 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 this fish species of giant catfish in our country, it is usually cultured in ponds. Due to the defects of pond culture itself, no more than 1000 gi...

Problems solved by technology

[0003] However, after the introduction of this fish species of giant catfish in our country, it is usually cultured in ponds. Due to the defects of pond culture itself, no more than 1000 giant catfish can be cultured in one mu of ponds, and its output can only reach 750Kg It is also inconvenient to catch when harvesting, which consumes a lot of manpower and material resources to catch, which reduces economic benefits. In the prior art, there are also methods of using net cages for breeding, but the way of using net cages is not conducive to fish growth and high cost , in addition, the existing feeding method is unscientific so that the output is limited
