Problems solved by technology

[0003] Traditional adult crab breeding methods generally adopt static water seedling cultivation and surface oxygenation, which has low oxygen delivery efficiency and low stocking density, which is not conducive to increasing the output of adult crabs and reduces the economic benefits of the enterprise. Therefore, a method to increase the output of adult crabs is proposed. Methods

Embodiment 1

[0024] see figure 1 , the present invention provides a technical solution:

[0025] Step S1, pond maintenance: desilting and disinfecting the pond, building anti-escape facilities, and building a nano-micron gas-liquid two-phase generation system;

[0026] Step S2, preparing a nano-micron gas-liquid two-phase system: preparing a nano-micron gas-liquid two-phase system through a nano-micron gas-liquid two-phase generation system, including a preparation unit arranged near the water body, a water inlet pipe and a delivery pipe connected to the water body, through The metal tube extracts the water supply of the aquaculture system and supplies the preparation unit to prepare the nano-micron gas-liquid two-phase system. The nano-micron gas-liquid two-phase system prepared by the preparation unit is transported and diffused into the aquaculture water body through the delivery pipe. The micronano two-phase system The gas phase is air, oxygen or ozone, the liquid phase is water, and ...

Abstract

The invention discloses a method for increasing the yield of adult crabs. The method comprises the following steps of 1, preparing a pond, specifically, dredging and disinfecting the pond, constructing an anti-escape facility, and constructing a nano-micron gas-liquid two-phase generation system; 2, preparing a nano-micron gas-liquid two-phase system, specifically, preparing the nano-micron gas-liquid two-phase system through the nano-micron gas-liquid two-phase generation system, conveying the nano-micron gas-liquid two-phase system, and uniformly distributing the nano-micron gas-liquid two-phase system in an adult crab culture water body; 3, putting the adult crabs, putting bait regularly, and enabling the adult crabs to grow; and 4, discharging the adult crabs from the pond. The method can increase the oxygen content of the water body, improve the water quality of adult crab culture water, and improve the survival rate, yield and quality of the adult crabs.

Description

technical field [0001] The invention relates to the technical field of adult crab cultivation, in particular to a method for increasing the yield of adult crabs. Background technique [0002] Crabs belong to the class Molecula, decapod order, and are crustaceans. The body is protected by a hard shell and breathes by gills. In terms of taxonomy, it is the same animal as shrimp, lobster, and hermit crab; most types of crabs live in the sea or offshore areas, and some live in fresh water or land. Common crabs include swimming crabs, swimming crabs, and blue crabs And Chinese mitten crab (river crab, hairy crab, clear water crab), etc.; [0003] Traditional adult crab breeding methods generally adopt static water seedling cultivation and surface oxygenation, which has low oxygen delivery efficiency and low stocking density, which is not conducive to increasing the output of adult crabs and reduces the economic benefits of the enterprise. Therefore, a method to increase the outp...
