Embodiment 1

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

[0018] (1) Soak the megalopa after molting for 5 times in the prepared strengthening solution for 10-12 minutes. The strengthening solution is prepared by mixing the strengthening agent with 450 times deionized water. The strengthening agent is prepared by 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, and 1.0 parts of vitamin D. Construction of temporary storage pools, the bottom of the temporary storage pools A 7-centimeter-thick bottom mud was applied, and the depth of the pool was 65 centimeters. Aquatic plants were planted at the bottom of the holding pond. The planting area of ​​aquatic plants accounted for 40% of the total area of ​​the water body. Duckweed was planted around the pool, and the area of ​​duckweed accounted ...

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-fertile crab species used for cultivating river crabs. Background technique [0002] River crabs are also called "crabs" and "hair crabs". 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. The river crab is a large crustacean with a body divided into 21 segments. Since the head and thorax segments are heal...
