Problems solved by technology

Temporary breeding through equipment temperature control, high investment and high risk, and conventional temporary breeding methods, the mortality rate of river crabs is high, the survival rate is low, the plumpness of river crabs often does not meet the requirements, and the economic benefits of temporarily raising river crabs are not high. Some temporary farmers lose money

Embodiment 1

[0025] From 2009 to 2010, 6 river crab ponds were selected in the high-quality river crab large-scale breeding test base, and the original ecological off-season breeding and sales experiment of river crab ponds was carried out. 260kg of adult crabs are put into the pond, and no temperature control measures are taken in outdoor crab ponds. Commercial crabs can be cultured in the original ecology and out of season until the end of April.

[0026] (1) Transformation of the new type of off-season crab breeding pond: Change the conventional slope ratio of the crab pond from 1:3-5 to 1:1.5, and set a block with polyethylene mesh on the inner side of the pond, 30cm above the water surface, without Let the river crab go ashore to move and crawl, and consume physical strength. The entire crab pond is set with shallow water baiting area accounting for 30%, water depth 0.6m, deep water low temperature habitat area accounting for 30%, water depth 2.0m, buffer zone accounting for 40% (the ...

Embodiment 2

[0035] From 2011 to 2012, 6 river crab ponds were selected in the high-quality river crab large-scale breeding test base, and the original ecological delayed temporary breeding and anti-season sales experiment of river crab breeding ponds were carried out. 280kg of adult crabs are put in per mu, no temperature control measures are taken in outdoor crab ponds, and commercial crabs can be cultured in the original ecology and out of season until the end of April.

[0036] (1) Transformation of new-type off-season crab ponds: Change the conventional slope ratio of crab ponds from 1:3-5 to 1:1.3, and set up a block with polyethylene mesh on the inside of the pond ridge, 30cm above the water surface. Let the river crab go ashore to move and crawl, and consume physical strength. The shallow water baiting area accounts for 30% of the whole crab pond, the water depth is 0.6m ~ 0.8m, the deep water low temperature habitat area accounts for 30%, the water depth is 2.0m ~ 2.5m, and the bu...

Embodiment 3

[0045] From 2012 to 2013, 6 river crab ponds were selected in the high-quality river crab large-scale breeding test base, and the original ecological delayed temporary breeding and anti-season sales experiment of river crab ponds were carried out. 300kg of adult crabs are put in per mu, no temperature control measures are taken in outdoor crab ponds, and commercial crabs can be cultured in the original ecology and out of season until the end of April.

[0046] (1) Transformation of new-type off-season crab breeding ponds: Change the conventional slope ratio of crab ponds from 1:3-5 to 1:1.2, and set up a block with polyethylene mesh on the inside of the pond ridge, 30cm above the water surface. Let the river crab go ashore to move and crawl, and consume physical strength. The shallow water baiting area accounts for 30% of the whole crab pond, the water depth is 0.6m ~ 0.8m, the deep water low temperature habitat area accounts for 30%, the water depth is 2.0m ~ 2.5m, and the bu...

Abstract

The invention discloses a method for breeding river crabs in an original-ecology anti-season breeding pool. The method includes the following steps that the novel reformed anti-season breeding pool for river crabs is adopted, crab holes are manually formed, hornwort and waterweed are planted through net cages, the water temperature is controlled, energy is saved, no equipment temperature control measure is taken, the crabs are fed with spiral shells dynamically in the whole process, measures of conducting anti-season selling of goods crabs and the like are taken to further fatten the bred river crabs, after anti-season breeding and fattening, anti-season 'staggered time' selling is achieved, economic profits of the river crabs are remarkably raised, and meanwhile the survival rate and yield of the river crabs are remarkably raised.

Description

Technical field: [0001] The invention belongs to the off-season breeding technology of Chinese mitten crab commercial crabs. Specifically, by transforming the new original ecological off-season breeding pond of river crabs, artificially constructing the off-season breeding ponds, establishing passages with conventional river crab breeding ponds, and constructing aquatic plant floating beds , control the temperature of the water body, save energy, do not take temperature control measures for equipment, feed snails dynamically throughout the whole process, sell commercial crabs in off-season, put in 240kg to 300kg of adult crabs per mu, do not take temperature control measures in river crab ponds, and can breed commercial crabs in off-season It will be on the market until the end of April, greatly increasing the value of commercial crabs. Background technique: [0002] Anhui Province is a major aquatic province and the main production area of ​​river crabs in the country. With...
