Embodiment 1

[0017] A method for cultivating self-bred crab species for river crab culture, comprising the following steps:

[0018] (1) Soak for 10-12 minutes the larvae after molting for 10-12 minutes with the prepared strengthening solution. The strengthening solution is prepared by adding a strengthening agent to 450 times of deionized water. Made of the following ingredients: 6.5 parts of polylysine, 4.5 parts of calcium lactate, 3.5 parts of calcium gluconate, 2.2 parts of sodium chloride, 1.4 parts of vitamin C, 1.0 parts of vitamin D, the construction of the holding tank, the bottom of the holding tank 7 cm thick bottom mud was applied, and the water depth of the pool was 65 cm. Aquatic plants were planted at the bottom of the temporary holding tank. The planting area of ​​aquatic plants accounted for 40% of the total water area. ;

[0019] (2) Add the cooling liquid obtained by mixing isatis root, licorice and honeysuckle in a mass ratio of 7:4:1 and adding 100 times the volume o...

Abstract

The invention relates to the technical field of modern agricultural industry, and discloses a method for cultivating a self-bred crab species for river crab cultivation. The method comprises the stepsthat firstly, a reinforcing solution is used for treating river juvenile crabs, a storage pond is built for cultivation, the cultured juvenile crabs have high disease resistance, the growth speed isobviously better than juvenile crabs of the same variety, and the cultivated river crabs have strong physique, complete appendages and no injury, which reduces the cost of breeding, and has the effectof increasing the survival rate, reducing the prevalence rate, stabilizing the group behavior, reducing the disability rate and increasing the growth rate of crabs. The method effectively solves theproblem of the poor quality of crabs in the existing river crab culture, and provides a huge space for the sale of the products because of the strong adaptability of the crabs and the good nutrition and taste of the crabs, and the sales market is guaranteed. The river crab cultivation yield and the sales volume can be increased, the reality significance of culture risk loss is lowered, and the technical scheme is quite worthy of being used and popularized.

Description

technical field [0001] The invention belongs to the technical field of modern agricultural industry, and in particular relates to a method for cultivating self-bred crab seeds for cultivating river crabs. Background technique [0002] River crabs are also called "crabs" and "hair crabs". The head and chest are combined with a square-shaped cuirass and a hard texture. The front of the body has a pair of eyes, and the side has two pairs of very sharp crab teeth. The front pair of appendages of crabs are called chelipeds, and the surface is covered with downy hairs; after the chelipeds, there are 4 pairs of walking legs, which are flat and longer on the side; the abdominal limbs have been degenerated. The male and female crabs can be identified by their abdomen: the female abdomen is round, the male abdomen is triangular. The river crab is a large crustacean with 21 body segments. Since the head and thorax are mutually healed, the whole body is divided into two parts, the cep...
