Embodiment 1

[0055] This embodiment is used to illustrate the American shad culture system and culture method of the present invention.

[0056] (1) Build the American shad breeding system provided by the present invention.

[0057] First, excavate the culture pond: the cross section of the culture pond is isosceles inverted trapezoid, the bottom surface and the opening are rectangular, the depth of the culture pond is 4m, the width of the rectangular bottom surface is 15m, the length is 30m, the width of the rectangular opening is 25m, and the length is 40m A water inlet connected to the water source of the deep well and a drain connected to the drainage system are respectively arranged on both sides of the length direction of the culture pond, and the drain is arranged at the bottom of the culture pond.

[0058] Then, build the heat preservation shed: the heat preservation shed is built on the top of the breeding pond, the heat preservation shed includes arch rods, longitudinal tie rods,...

Embodiment 2

[0075] American shad was raised according to the same method as in Example 1, the difference being that the upper part of the transparent plastic film on the top of the insulation shed was covered with a sunshade film. By controlling the opening and closing of the transparent polyethylene plastic film on the side of the heat preservation shed and the sunshade film on the top of the heat preservation shed and the flow of deep water well water in the culture pond, the water body temperature of the American shad culture system is controlled. In the range of 17-22°C. The specific control method is: when the water body temperature of the shad culture system is higher than 21°C, open the transparent polyethylene plastic film on the side of the heat preservation shed, close the sunshade film on the top of the heat preservation shed and increase the flow of deep water well water, Make the water temperature in the culture pond not higher than 22°C; when the water body temperature of th...

Embodiment 3

[0078] American shad is raised according to the same method as in Example 1, the difference is that: the bottom of the culture pond of the American shad culture system is laid with three microporous aeration pipes connected with the aerator, and the aeration pipe is along the bottom of the culture pond. The length direction is buried at the bottom of the culture pond. Through the aeration tube, the dissolved oxygen of the culture pond water is controlled at 5-8mg / L. The specific control method is: when the dissolved oxygen of the culture pond water is lower than 5.5mg / L, the aerator is turned on to feed into the culture pond. Oxygen, to control the dissolved oxygen in the pond water at 5-8mg / L.

[0079] The survival rate of shad and the average weight of fish were calculated by sampling and counting method, and the results are shown in Table 1.

Abstract

The invention provides an Alosa sapidissima culture system, which comprises a culture pool, a heat-insulation shed erected above the culture pool and a deep well, wherein the heat-insulation shed comprises arch bars and longitudinal pull rods; the heat-insulation shed also comprises side upright posts and shed head upright posts, wherein the side upright posts are fixedly connected between the end parts of the arch bars and the ground, the shed head upright posts are fixedly connected between the end parts of the longitudinal pull rods and the ground, a fixed transparent film is covered on the top and front and rear end parts of the heat-insulation shed, and a transparent film capable of being rolled along the length direction of the side upright posts is covered on the side part of the heat-insulation shed; the culture pool is provided with a water inlet and a water discharge port, the water discharge port is located at the bottom of the culture pool and is connected with a drainage system; and a water source of the deep well is used for supplying water for the culture pool by the water inlet. According to the culture system, the problem that the temperature of the Alosa sapidissima culture system is difficult to regulate and control is solved by controlling the opening and closing of the transparent film and using water from the deep well.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an American shad cultivation system for American shad cultivation. In addition, the present invention also relates to a method for cultivating American shad, which uses the described American shad cultivation system. Background technique [0002] American shad meat is delicious and nutritious. Under the situation that Chinese shad is on the verge of extinction, the artificial breeding of American shad has a very broad prospect in my country. At present, more than a dozen provinces and cities including Guangdong, Zhejiang, Jiangsu, Shanghai, Hubei, Hunan and Tianjin have started large-scale cultivation of American shad. [0003] American shad is extremely delicate, and the fish body touches the net and loses scales. It is most suitable for growth in water bodies at 15-25°C. When the water temperature is lower than 10°C or exceeds 30°C, it will not eat and die. Many of the current Amer...
