Problems solved by technology

The monoculture of freshwater shrimp or crab is a high-density existence, which will cause a large amount of bait residue and metabolite deposition, and the organic pollution in the pond is extremely serious.
At the same time, a single cultured species will also lead to a single population of phytoplankton and microorganisms, resulting in deterioration of pond water quality, poor circulation of organic matter, and also provides rich nutrients for harmful microorganisms, leading to diseases

Embodiment 1

[0029] A new mode of polyculture of shrimp, crab and fish, the specific operation is as follows:

[0030] (1) Pond standard: The pond area is 6 mu, the pond depth is 1.5m, the slope ratio of the surrounding pond is 1:2, the pond water source is abundant and pollution-free, the injection and drainage system is separated, and the influent is filtered by a filter to prevent miscellaneous fish from entering and affecting the ecology System, the bottom is preferably loam, no leakage, the thickness of the silt is less than 10cm, dig 1~2 vertical or horizontal grooves at the bottom, for the habitat of freshwater shrimp and Chinese velvet crab, throw some tiles, bamboo slips or stones on the beach Heap, as a hiding place when shrimp and crab moult;

[0031] (2) Anti-escape facilities and oxygenation facilities: The height of the anti-escape facilities is 35cm, and the bamboo poles are fixed every 1m. The bamboo poles are buried in the soil for 30cm, and the bamboo poles are wound and ...

Embodiment 2

[0038] A new mode of polyculture of shrimp, crab and fish, the specific operation is as follows:

Abstract

The invention relates to the technical field of aquaculture, in particular to a novel mode of polyculture of shrimps, crabs and fish. From June 20th to July 10th, young macrobrachium nipponense is put, the putting density is 80000-100000 ind / mu, and hypophthalmichthysmolitrix of 15-25 ind / mu and hypophthalmichthys nobilis of 25-35 ind / mu are put; from August 10th to August 20th, juvenile crabs areput, and the putting density is 1200-1500 ind / mu. The novel mode of polyculture of the shrimps, crabs and fish has the advantages that the occurrence of diseases is prevented and controlled, the manpower and bait cost is saved, the market risk is reduced, the stable production and stable harvest of the shrimps and crabs are promoted, and the comprehensive benefits are improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a new mode of polyculture of shrimp, crab and fish. Background technique [0002] Freshwater shrimp is also known as river shrimp. The cultivation technology of freshwater shrimp belongs to relatively mature artificial aquaculture technology, especially the pond culture of freshwater shrimp is the most; the cultivation technology of freshwater shrimp not only refers to pure freshwater shrimp cultivation, but also includes the cultivation of freshwater shrimp with other species. Polyculture, such as one or more kinds of polyculture with other fish species or soft-shelled turtle species; however, due to the different breeding habits of different species, the techniques of pure culture or polyculture are different, so in order to improve the breeding efficiency, farmers especially pursue more There are also differences in the specific farming methods adopted to achieve the lowes...
