Abstract

The invention belongs to the field of genetics and biodiversity protection science, and discloses application of a mitochondrion COII gene to identification of Eriocheir sinensis, Japanese Mitten Crabs and / or mitten crabs in a water system of South China. The invention also discloses a method for identifying the Eriocheir sinensis, the Japanese Mitten Crabs and / or the mitten crabs in the water system of South China. The method adopted can effectively and accurately identify the crabs, and requires small sample size, so as to provide a more ideal approach for genetic discrimination and fine breed cultivation of the crabs.

Description

technical field

[0001] The invention belongs to the fields of genetics and biodiversity conservation. More specifically, the present invention relates to a molecular genetic identification method for Chinese mitten crabs, Chinese southern water systems (Guangdong Pearl River, Guangxi Nanliujiang) mitten crabs and Japanese mitten crabs . Background technique

[0002] Chinese mitten crab (Eriocheir sinensis) and Japanese mitten crab (Eriocheir japonica) both belong to the phylum Arthropoda, the class Crustaceae, the order Decapoda, the family Grapsidae, and the genus Eriocheir ). The genus Eriocheir generally includes four species: Eriocheir sinensis, Eriocheir japonica, Eriocheir mitten and Eriocheir angustifolia. In addition, there are Nanliu river mitten crabs in the southern water system of China. The mitten crabs and mitten crabs are small and have no economic value. Chinese mitten crab and Japanese mitten crab are relatively large individuals, and are economic specie...
