Embodiment Construction

[0030] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Please refer to figure 1 ,Should figure 1 Shown is a flowchart of an embodiment of the method for saving and breeding fish and shrimp breeding populations of the present invention. In this embodiment, Macrobrachium rosenbergii is taken as an example, and its breeding method is described in detail, especially the process of its seed saving and mating.

[0032] Such as figure 1 Shown, this embodiment carries out the process of breeding Macrobrachium rosenbergii as follows:

[0033] Step 11: Obtain the measured values ​​of all test individual breeding target traits in this generation.

[0034] Macrobrachium rosenbergii is the largest individual freshwater prawn in the world. According to incomplete statistics, by 2009, the number of seedlings of Macrobrachium rosenbergii in China was about 25 billion...

Abstract

The invention discloses a stocking and mating method for a fish and shrimp group, comprising the following steps of: acquiring a selection index; sequentially selecting a certain amount of families from high family selection index to low family selection index as stocking families under a limited consanguinity coefficient; selecting male parent / female parent families and paired female parent / male parent families from the stocking family according to the sequence from the high family selection index to the low family selection index; and mating each male parent with corresponding female parent according to the sequence from high individual selection index to low individual selection index, creating male parent / female parent family mating groups, and form the next generation breeding group by all the mating groups. According to the stocking and mating method disclosed by the invention, a stocking and mating process of a breeding group is controlled according to the selection index and the consanguinity coefficient, and genetic progress of target character is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of aquatic genetics and breeding, and in particular relates to a method for saving and breeding fish and shrimp breeding populations. Background technique [0002] Artificial selection produces genetic progress and also increases the level of inbreeding in breeding populations. Compared with livestock animals such as pigs and cattle, aquatic animals such as fish and shrimp are small in size and large in egg production, and can establish families on a large scale. The accuracy of genetic evaluation is high, high-intensity selection can be implemented, and higher genetic progress can be obtained. . But on the other hand, there may also be a situation where the next generation group is composed of a small number of offspring of the "founder". For example, in the basic population of the coho salmon Oncorhynchus kisutch, 50% to 70% of the remaining seed parents have no parents in the fourth generation. offsprin...
