Problems solved by technology

The male and female of the river crab can be distinguished from its abdomen: the abdomen of the female is round, and the abdomen of the male is triangular. Because of its own nutritional value and medicinal value, river crabs are deeply loved by people, so they have a great demand for human beings. Therefore, river crabs There are also a lot of cultured river crabs, but due to the specific living habits and growth status of river crabs, the survival rate is very low and the quality is relatively poor. In this way, the farmers are very criticized, and the enthusiasm for breeding is not strong.

Embodiment 1

[0025] A culture method for river crabs, comprising the following steps:

[0026] (1) Construction of crab ponds: Build crab ponds in places with sufficient water sources, no pollution of water quality, less silt at the bottom of the pond, more grass, and relatively secluded locations, with an area of ​​5 acres and a water depth of 1 meter; Slope, the bottom of the pool is inclined to the side of the water outlet, and a circular or square bottom groove for collecting crabs is dug in front of the water outlet. The depth of the groove is 20 cm, and the area is 10 square meters. Slope, grass planting on the slope, drainage outlet and water injection outlet in the crab pond are all blocked with stainless steel mesh.

[0027] (2), crab species stocking:

[0028] a 1 1. Disinfection of clear pond: Before stocking crab species, drain the pond water, remove humus and silt at the bottom of the pond, expose the bottom of the pond to the sun, remove ferocious fish and soft-shelled turt...

[0041] A culture method for river crabs, comprising the following steps:

[0042] (1) Construction of crab ponds: Build crab ponds in places with sufficient water sources, no pollution of water quality, less silt at the bottom of the pond, more grass, and relatively secluded locations, with an area of ​​10 mu and a water depth of 1.5 meters; the bottom of the crab pond is flat and set at a ratio of 1:3 Slope, the bottom of the pool is inclined to the side of the water outlet, and a circular or square bottom groove for collecting crabs is dug in front of the water outlet. The depth of the groove is 30 cm, and the area is 20 square meters. Slope, grass planting on the slope, drainage outlet and water injection outlet in the crab pond are all blocked with stainless steel mesh.

[0043] (2), crab species stocking:

[0044] a 1 1. Disinfection of clear pond: before stocking crab species, drain the pond water, remove humus and silt at the bottom of the pond, expose the bottom of t...

Abstract

The invention relates to a river crab culturing method, and relates to an aquaculture method. The method comprises the steps of crab pond construction, crab fry stocking, feeding management, and pond crab catching. The method has the following advantages: no professional equipment is needed; no culture pollution is caused; the culturing technology is standardized and normalized; stocking is reasonable; and catching is prompt. Compared to traditional river crab culturing technologies, the method is significantly improved. With the method, river crab product yield and quality are effectively improved.

Description

technical field [0001] The invention relates to a method for aquaculture, in particular to a method for cultivating river crabs. Background technique [0002] River crabs are also called "crabs" or "hair crabs", and belong to the crustaceans of the phylum Arthropoda. The carapace formed by the combination of the head and the chest is square and hard. There is a pair of eyes on the front of the body, and two pairs of very sharp crab teeth on the side. The first pair of appendages of the crab are called chelicerae, and the surface is covered with fluff; behind the chelicerae, there are 4 pairs of walking legs, with flat sides and longer; the abdominal limbs have degenerated. The male and female of the river crab can be distinguished from its abdomen: the abdomen of the female is round, and the abdomen of the male is triangular. Because of its own nutritional value and medicinal value, river crabs are deeply loved by people, so they have a great demand for human beings. There...
