Problems solved by technology

Farmers are not very enthusiastic about the farming of Penaeus vannamei. Although the indoor factory farming of Litopenaeus vannamei still has a certain scale, the area of ​​outdoor shrimp ponds is shrinking day by day, and a large number of outdoor shrimp ponds are at a loss.
For shrimp diseases, the best way at present is prevention. Biological prevention is better than drug prevention. The society urgently needs a high-yield, high-efficiency, and environmentally-friendly efficient utilization model of shrimp ponds to solve the bottleneck problem of outdoor shrimp pond utilization in the north.

Embodiment 1

[0045] Embodiment 1, a kind of shrimp pond net cage combination cultivation method:

[0046] (1) Shrimp pond transformation and net cage placement; said shrimp pond transformation and net cage placement are excavating a 2.5 meter deep and 8 meter wide ring ditch in the shrimp pond, and placing a 6×6× 3 meters of fixed cages, the bottom of the cage is 10 cm from the bottom of the ditch;

[0047] (2) Putting broodstock of white prawns with eggs; in spring, the water temperature in the shrimp pond is raised to 13°C, and the water temperature is the temperature of the pool surface, which is measured at 10:00 in the morning, the same below; 0.5-0.6 When the water temperature rises to 17°C, scatter the broodstock shrimp in the shrimp pond, and replace the net clothes at the same time;

[0048] (3) Penaeus monodon seedlings are thrown in; the water temperature in spring is raised to 17°C, and each net cage is put into 1000 tail body long 1 cm seedlings of Penaeus monodon for tempora...

Embodiment 2

[0060] Embodiment 2, a kind of net cage combined culture method in shrimp pond:

[0061] (1) Shrimp pond transformation and net cage placement; said shrimp pond transformation and net cage placement are to excavate a 3.5 meter deep and 10 meter wide ring ditch in the shrimp pond, and place a 6×6× 3 meters fixed cage, the bottom of the cage is 20 cm from the bottom of the ditch;

[0062] (2) White prawns holding eggs are put in; the water temperature in the shrimp pond is raised to 14°C in spring, and the water temperature is the temperature of the pool surface, which is measured at 10:00 in the morning, the same below; 0.6 to 0.8 of white prawns are put in each cage. When the water temperature rises to 18°C, scatter the broodstock shrimp in the shrimp pond, and replace the net clothes at the same time;

[0063] (3) Penaeus monodon seedlings are thrown in; in spring, the water temperature is raised to 18°C, and each net cage is put into 2000 tail body lengths of 1 to 2 centime...

Embodiment 3

[0075] Embodiment 3, a kind of shrimp pond net cage combination culture method experiment:

[0076] Experiment time and place: In 2017, in the shrimp pond of the experimental base in Lianyun District.

[0077] experiment procedure:

[0078] On March 2, 55 acres of shrimp ponds were rebuilt, and a ring trench with a depth of 3 meters and a width of 9 meters was excavated in the shrimp pond. A fixed cage of 6×6×3 meters was placed in the trench every 8 meters. The distance between the bottom of the cage The bottom of the ditch is 15 cm;

[0079] On April 12, 2017, 0.5 to 1 catties of broodstock broodstock of white prawns were placed in each cage, and the water temperature was 13°C. During the temporary breeding period, blue clams were fed and overfeeding;

[0080] On May 31, when the water temperature was 18°C, the broodstock shrimp were scattered into the shrimp pond, and the nets were changed at the same time. 15,000 Penaeus monodon seedlings with a tail length of 1.0 to 1.2...

Abstract

The invention relates to a combination culture method of shrimp ponds and net cages: it comprises the transformation of shrimp ponds and the addition of net cages, the addition of broodstock of white shrimp, the introduction of young Penaeus monodon, the introduction of juvenile black prawns, the introduction of ginseng seedlings, and the stage-by-stage feeding of bait and other steps. The method of the present invention introduces white shrimp, Penaeus monodon, cuttlefish and sea cucumber into the same culture pond through the protective effect of the net cage, improves the stability of the ecosystem, and effectively controls the incidence of diseases of white shrimp and Penaeus monodon, At the same time, make full use of the water body, improve the productivity of the water area, and increase economic benefits, which is suitable for promotion in outdoor shrimp ponds in northern China.

Description

technical field [0001] The invention relates to a combined culture method of cages in a shrimp pond, in particular to a method for temporarily cultivating brood broodstock of white prawns, Penaeus monodon seedlings, juvenile golden squid and sea cucumber seedlings in a shrimp pond by using a cage in a shrimp pond. Background technique [0002] In our country, the shrimp industry has long been an important pillar industry of the mariculture industry, which has brought very obvious economic and social benefits to our country. However, since 1993, shrimp diseases once brought China's shrimp farming industry into a slump. In the northern part of China, there are more and more aquaculture diseases of Penaeus prawn and Litopenaeus vannamei, the size of commercial shrimp is too small, and the pollution of aquaculture is becoming more and more serious. Farmers are not very enthusiastic about the cultivation of Chinese prawns. Although the indoor factory farming of Litopenaeus vanna...
