Embodiment 1

[0015] The culture method of the giant barb of the present embodiment may further comprise the steps:

[0016] A. Establish a culture pond, which is provided with a water inlet and an outlet, and one side of the culture pond is provided with an aeration pump connected to the culture pond, and the culture pond is divided into a fry area, a small fish area and a large fish area by two fish nets In the three breeding areas of the district, the grid size of the first fish net allows fry to pass but not small fish, and the grid size of the second fish net allows small fish to pass but not large fish;

[0017] B. Put fish fry in the fry area and put fry feed in the fry area. As the fry grow up, put small fish feed in the small fish area in the middle term, then put in big fish feed in the big fish area, and put all the big fish feed in the later stage;

[0018] C. Control the water temperature in the culture pond to 25°C, dissolve oxygen to 3 mg / L, feed three times a day, drive the ...

[0024] C. Control the water temperature in the culture pond to 27°C, dissolve oxygen to 4 mg / L, feed three times a day, drive the ...

Embodiment 3

[0027] The culture method of the giant barb of the present embodiment may further comprise the steps:

[0028] A. Establish a culture pond, which is provided with a water inlet and an outlet, and one side of the culture pond is provided with an aeration pump connected to the culture pond, and the culture pond is divided into a fry area, a small fish area and a large fish area by two fish nets In the three breeding areas of the district, the grid size of the first fish net allows fry to pass through but does not allow small fish to pass through, and the grid size of the second fish net allows small fish to pass through but not large fish;

[0029] B. Put fish fry in the fry area and put fry feed in the fry area. As the fry grow up, put small fish feed in the small fish area in the middle term, then put big fish feed in the big fish area, and put all the big fish feed in the later stage;

[0030] C. Control the water temperature in the culture pond to 30°C, dissolve oxygen to 5 ...

Abstract

The invention discloses a breeding method of barbus capito. The method comprises the following steps that A, a breeding pond is built and divided into the three breeding areas including the fry area,the small fish area and the large fish area through two fishing nets; B, fry are bred in the fry area, and fry feed is added to the fry area; C, the water temperature of the breeding pond is controlled, oxygen dissolution is conducted, feeding is conducted three times every day, the fish school is driven at regular time, the mobility of the fish school is improved, and the density of the fish school is controlled; D, harvesting is conducted when the weight of each fish reaches 650-750 g. By adopting the method, by enlarging the activity range and improving the physique of the fry, the survivalrate is guaranteed, by driving the fish school at regular time, the uniformity of the fish school in all the breeding areas is improved, the reasonable feed adding means is beneficial to dispersion of the fish school, most fry identical in specification can be gathered in any area through partition breeding, the feeding concentricity is guaranteed, and the feeding effect is improved.

Description

technical field [0001] The invention relates to a technique for cultivating fish, in particular to a method for cultivating giant 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, 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...
