High-yield breeding method for barbus capito

Abstract

The invention discloses a high-yield breeding method a barbus capito, which comprises the following steps of: A, establishing three integrated culture ponds which are sequentially arranged from top tobottom, wherein sections of inclined transition surface are arranged between each culture pond, and water flows through the inclined transition surface; B, stocking fries in the last culture pond andthrowing fry feed, regularly driving the fries to enable part of the fries to overturn the inclined transition surface to enter the last culture pond along with the growth of the fries, throwing small fish feed in the middle culture pond, and throwing large fish feed in the first culture pond; C, controlling the water temperature of the culture ponds, dissolving oxygen and feeding every day; D, harvesting and throwing the fries. The method has the advantages that the produced fish body is determined to be healthy and active through the free overturn capability of the fish body, so that the yield and the quality of the fish body are improved, the physique of the fish body is increased through the driving mode, the classification of the fish body is facilitated, and circulating water can beformed to increase the water activity and improve the survival rate.

Description

Technical field [0001] The invention relates to a fish breeding technology, in particular to a method for high-yield breeding of large filet. Background technique [0002] The giant lepidopteran belongs to the family Cyprinidae, the subfamily, and belongs to the genus Carp. It is a eutrophic fish with delicious meat, fast growth, strong stress resistance, salt and alkali resistance and other excellent characteristics. It has wide eating habits, fast growth, delicious meat, salt-alkali tolerance, and strong adaptability. It is more cold-tolerant than the barbs, such as barb, spine, black spine, and golden scorpion, which enriches the breeding species of barbs in northern my country. [0003] However, in the prior art, the large filefish are usually bred directly in the pond. Due to the defects of pond culture, no more than 1,000 large filefish can be cultured in one acre of pond, and the output only reaches 750Kg / mu and is captured at harvest. It is inconvenient and consumes a lo...

Problems solved by technology

[0003] However, in the prior art, large barbs are usually directly stocked in ponds. Due to the inherent defects of pond culture, one mu of ponds can only breed no more than 1000 large barbs, and its output only reaches 750Kg / mu and is captured when harvesting. It is also inconvenient, and consumes a lot of manpower and material resources to catch, which reduces economic benefits. In the prior art, there are also methods of using cages for breeding, but the way of using cages is not conducive to the growth of fish bodies and the cost is high
