Problems solved by technology

After the seedlings are put in, because the individual is small and the sand is buried, the early management is very difficult, the survival rate of the seedlings is only about 30%, and the quantity in the later stage is difficult to grasp, resulting in a general yield of less than (750kg / hm²) and instability

Embodiment 1

[0046] The industrialized large-scale seed cultivation device of Penaeus japonicus of the present embodiment, refer to the attached Figure 1-2 , including a plurality of cultivation ponds 12 located in the cultivation chamber. The cross section of the cultivation pond 12 is circular. The cultivation pond 12 is provided with temperature control, water supply and air supply devices. In the air-lift device 11 that inflates into the cultivation pond 12 and can drive the pool water to rotate and flow, a drainage standpipe 1 is installed at the drain outlet at the bottom of the cultivation pond 12, and a part of the pipe body of the drainage riser 1 near the bottom of the cultivation pond 12 is provided with drainage Hole 2, the bottom of drainage standpipe 1 is equipped with blowdown pipe 3, and one end of blowdown pipe 3 is inserted in the seedling collection groove 4; A circular sewage collection area is formed; the gas lift device 11 includes an outer tube 5 that is at the same...

Embodiment 2

[0048] The industrial large-scale seed cultivation method of Penaeus japonica in this embodiment comprises the following cultivation steps:

[0049] 1. Cultivation room and pool setting

[0050] Cultivation room area 600~1000m 2 , with a glass fiber reinforced plastic or plastic membrane roof, the roof shading rate reaches more than 80%, and the indoor light intensity is maintained at 500~1000lx;

[0051] The cultivation pool 12 is built indoors. The cultivation pool 12 is circular, with a diameter of 5m, a pool depth of 1.4m, and an effective water depth of 1.1-1.2m; the middle of the cultivation pool is drained, and the gradient from the bottom of the pool to the drain is 4-6%. Φ110cm pvc drainage riser 1; drainage riser 1 from the bottom to 50cm, every cm 2 Drill one Φ0.3cm drainage hole 2; the drainage standpipe 1 is connected to the sewage valve 10 outside the pool through the sewage pipeline 3 pre-buried at the bottom of the pool, and the length 100cm×width 80cm×is pre...

Abstract

The invention relates to a factory-like large-scale seed culture device and method for marsupenaeus japonicus, and belongs to the technical field of prawn farming. The method includes the following processing steps that 1, a culture pond is constructed; 2, sanding is conducted; 3, a gas-lift unit is installed; 4, disinfecting is carried out; 5, inflow is performed; 6, seeds are put in; 7, the water color is adjusted; 8, bait is thrown; 9, the water quality and growth conditions are monitored; 10, the seeds are moved out of the pond. According to the method, factory-like high-density and large-scale (about 3 cm) seed culture can be conducted, the culture period in the culture pond is shortened, and the large-scale seed culture device and method for the marsupenaeus japonicus which is cultured for multiple batches in one year are realized. By the adoption of the method, the body length of the seeds is cultured to be about 3 cm from 0.8 cm, and the survival rate of the marsupenaeus japonicus can reach 80%; the marsupenaeus japonicus is cultured into commercial sized marsupenaeus japonicus from the body length of about 3 cm, the survival rate of the marsupenaeus japonicus can reach 70%, and the yield can reach 1500-2250 kg / hm2.

Description

technical field [0001] The invention relates to an industrial large-scale seed cultivating device and a cultivating method of Penaeus japonicus, belonging to the technical field of prawn culture. Background technique [0002] Shrimp is a popular aquatic food. In recent years, the high-level ponds and industrialized high-density aquaculture water bodies of domestic and foreign species such as Litopenaeus vannamei and Penaeus monodon have increased rapidly, and the technology has been improved day by day. The equivalent unit yield has reached 7.5kg / m3 2 above. As an excellent variety of prawns, Penaeus japonica is favored by the market because of its resistance to dry transportation and can be sold live. . Penaeus japonicus is distributed in the Bohai Sea, the Yellow Sea and the western coast of the Korean Peninsula in China; in the coastal areas of my country, it is cultivated in both the north and the south. Because Penaeus japonica has the habit of burrowing in sand, mos...
