Abstract

The invention discloses a method for cultivating crabs using circulating water with low emission. Crabs are individually separated in a cultivation container in a crab fattening process. A water pump injects clean water into a water inlet pipe to clean a fattening water channel unit. A plurality of fattening water channels are stacked up when used, to adapt to corresponding designed yield and water body processing capability. The upper edge opening of a top fattening water channel unit covers a cover plate to prevent crabs from escaping when the fattening water channels are stacked up. When the fatten water channels are cleaned, a sewage draining exit is opened, the water inlet pipe is opened to the maximum, water can quickly flow to the sewage draining exit along a water guide strip, an effect of sewage discharge is better compared with the prior art. The method for cultivating crabs using circulating water with low emission is low in management cost, automatic in clean, less in chip deposition and good in washing effect, the body surface of crabs can be cleaned, and the method can promote growth of the crabs.

Description

technical field [0001] The invention relates to a method for temporarily raising and fattening aquatic products in large-scale circulation, in particular to a low-emission method for raising crabs in circulating water. Background technique [0002] The traditional method of obtaining red crabs is generally to catch swimming crabs from the sea, sort them manually, and then sell them in grades. In the normal breeding process, crabs have to shed their shells many times in their lifetime (some people think that the crab stage needs to be Increase the number of shelling). The molting of a crab not only means its development, but also a necessary step for its growth. Crab molting will choose a good environment. They generally choose to do it in relatively quiet, shallow water areas with overgrown aquatic plants and easy concealment. After moulting, the new body that was originally folded in the old shell gradually unfolds, and the body grows accordingly. Usually, the faster the...
