Embodiment Construction

[0062] A method for three-dimensional cultivation of large-scale river crabs and soft-shell crabs in indoor circulating water includes breeding equipment and a breeding method, and is characterized in that: the breeding equipment includes an indoor circulating water three-dimensional multi-purpose aquatic product ecological breeding device and a supplementary light; The indoor circulating water three-dimensional multi-purpose aquatic product ecological breeding device includes a breeding box, a shelf, a biofilter, a water storage tank, a circulating water pump, an aquaculture constant temperature machine, an aerator and connecting pipelines; the breeding box is flushed by a detachable The hole isolation plate is divided into multiple single rooms; the cover of the breeding box is made of transparent material; the supplementary light is installed at the bottom of the shelf laminate above the breeding box; at least one sand filter is added in front of the water inlet pipe of the b...

Abstract

The invention belongs to the field of aquaculture, and relates to a method for breeding large river crabs and soft crabs in indoor circulating water in three-dimensional mode. According to the method, an ecological breeding device and a breeding method are involved. Bionic breeding is performed according to the growing characteristics of the river crabs. A breeding box can guarantee saturated dissolved oxygen supplying through oxygen supplying of interlayer micro-holes in the bottom, the rapid growing demands of the river crabs can be met, and the illness problem of the river crabs can be solved. An aquaculture constant temperature machine sets the optimal temperature for growth of the river crabs, and the speed of effective accumulative temperature increasing is reduced. The components of breeding water can be adjusted at any time so that the shelling requirements of the river crabs can be met. The river crabs are bred in independent chambers, the survival rate of the river crabs can be more than 95 percent, the expense of purchasing breeding crabs can be reduced, and the recapture rate can be 100 percent. Palatable bait is provided, waste is changed into wealth, meat and vegetables are matched, more nutrients are obtained, and money can be saved. People do not live by depending on the weather any more, the river crabs can be produced at all seasons, and the stable, high and efficient yield is guaranteed. It seems that the investment is large, but from a long-term view, tens of times of benefits can be obtained through the method compared with other breeding methods. The method can also be used for river crab breeding.

Description

Technical field: [0001] The invention relates to aquatic product cultivation, in particular to a method for stereoscopically cultivating large-sized river crabs and soft-shell crabs with indoor circulating water. technical background: [0002] The scientific name of the river crab is the Chinese mitten crab, and the common name is crab, hairy crab, clear water crab, hairy crab, etc., and belongs to the crustacea of ​​the phylum Arthropoda. River crab meat is tender and delicious, rich in nutrition, has both food value and medicinal value, and is deeply loved by the public. [0003] As we all know, the price of hairy crabs varies greatly depending on the specification. According to reports, each river crab weighing less than 100 grams sells for more than 10 yuan per 500 grams; the price of each 200-gram male crab and each 150-gram female crab ranges from 140 to 160 yuan per 500 grams. In between, there is little fluctuation; the price of each extra-large hairy crab over 250...
