Problems solved by technology

Preliminary results show that the growth traits of Macrobrachium japonicus are more suitable for family selection or intergroup hybridization, but due to the limitations of individual oviposition rate, survival rate and breeding facilities, it is difficult to carry out large-scale family breeding
However, the mating rate and survival rate of previous attempts are difficult to achieve the purpose of efficiently constructing Macrobrachium japonicus families

Embodiment 1

[0036] A method for establishment of giant macrobrachium aquarium family and standardized seed cultivation, comprising the following steps: A, setting seed cultivation facilities; B, selection and mating of parent shrimp; C, standardized management of different larval developmental stages;

[0037] Wherein step A is provided with seed cultivation facility and comprises:

[0038] Add oxygenation equipment to a rectangular or round aquarium with a cover. At the same time, add bionic aquatic plants to the aquarium, and use air stones to inflate each aquarium separately. It is fixed at a suitable height on the wall of the aquarium, and with the addition of an air volume regulating valve, it is convenient to adjust the air output and air output frequency; the light in the aquarium adopts natural light, because the larvae of Macrobrachium prawns are phototaxis and adult shrimps are photophobic, according to the actual light Intensity can be used to post black plastic bags on the out...

Abstract

The invention provides a method for establishing a macrobrachium nipponensis aquarium family and carrying out standardized young shrimp culture. The method comprises the following steps: A, setting a young shrimp culture facility; B, selecting parent shrimps and mating; and C, carrying out management standardization in different paedomorphosis stages. The method has the advantages that a process is established for standardization of a macrobrachium nipponensis family, the family culture success rate reaches more than 90%, the influence of environmental factors on family establishment and young shrimp culture is reduced, and the macrobrachium nipponensis culture efficiency is improved.

Description

technical field [0001] The invention relates to an artificial breeding method of Macrobrachium japonicus, in particular to a method for establishing a family of Macrobrachium japonicus in an aquarium and standardizing seedling cultivation. Background technique [0002] Macrobrachium nipponense (Macrobrachium nipponense) belongs to Crustacea, Decapoda, Longarm Shrimpidae, Macrobrachium genus, also known as freshwater shrimp, commonly known as river shrimp, is an important freshwater edible shrimp in my country. Its meat is delicious. Fried river shrimp is A very popular dish, so the market demand for river prawns is very large and the economic value is high. However, due to problems such as water pollution and overfishing in recent years, the wild resources of Macrobrachium japonicus have been severely damaged, and the protection of wild resources of freshwater shrimp has been put on the agenda. In the past, the production mode of artificially cultivating Macrobrachium japoni...
