Problems solved by technology

Indoor small water bodies (such as experimental tanks, etc.) river crab culture needs to overcome two key problems: one is that it is easy to die during the breeding process, and the other is that the number of molts is small
At present, there are no research and test reports in this area in China.

specific Embodiment approach

[0017] 1. Construction of indoor breeding facilities

[0018] Choose a circular fiberglass tank with a diameter of 70cm and a depth of 70cm, with a water volume of 250L. Breeding facilities can also be selected according to the experimental materials, and the best effective water volume is required to be more than 200L.

[0019] Placement of shelters: Because river crabs live in bottom habitats, they like to live in seclusion or caves, and especially like to molt in places with shelters. Therefore, tiles (length 37cm×width 25cm, wave distance 7.5cm, wave height 2.5cm) were placed in each experimental tank for shelter.

[0020] 2. Selection of crab species

[0021] Selection of crab species: neat specifications, no disease or injury, sound appendages, specifications and selection according to test or growth requirements.

[0022] 3. Stocking density

[0023] The stocking density is better with each crab having a water volume of 50L.

[0024] 4. Daily management and bait fe...

Abstract

The invention discloses a method for breeding Eriocheir sinensis in an indoor water tank. The method comprises the steps: (1) construction of a breeding environment in the indoor test water tank; (2) selection of Eriocheir sinensis; (3) realization of reasonable stocking density; (4) daily management and bait feeding; and (5) management during molting. The method for breeding the adult Eriocheir sinensis in the indoor water tank is developed by combining ecological breeding engineering and aiming at breeding in the indoor water tank according to the characteristics of the breeding biology and the autecology of the Eriocheir sinensis. Proved by the technical practices of the inventor, the adult Eriocheir sinensis breeding in the indoor water tank succeeds, and the method has great significance in the field of breeding and cultivating Eriocheir sinensis.

Description

technical field [0001] The invention belongs to the field of aquaculture, and relates to a method for growing Chinese mitten crab (Eriocheir sinensis) in an indoor water tank at the crab-growing stage. Background technique [0002] Eriocheir sinensis, commonly known as river crab, is a typical crustacean. It will experience about 20 molts in its life, and its body will grow once every time it molts. The size of individual river crabs depends on the number of molting times and the growth of the body after each moulting, but different environmental conditions have a great impact on the number of moulting times and post-moulting growth of river crabs, resulting in great differences among individual river crabs. In addition, within two days after the crab moults, its body is soft, and if it is attacked by other creatures, it will easily cause death. This molting biological characteristic of river crab requires that in the culture process of river crab, good culture environment ...
