Disclosed are a probe method-based kit and method for tracking a behavior trajectory of Acipenser dabryanus Dumeril released upstream of the Yangtze River. By analyzing mitochondrial DNA sequences of Acipenser dabryanus Dumeril and common fish species in the Yangtze River basin, a pair of specific primers ND5-F4 / ND5-R4 capable of specifically amplifying mitochondrial DNAs of Acipenser dabryanus Dumeril and a Taqman fluorescent probe ND5 Probe 4 are designed and screened. A kit composed of the specific primers, the Taqman fluorescent probe, and a ddPCR master mix is used to carry out ddPCR testing on environmental DNA samples collected before and after release, so that a behavior trajectory of the released Acipenser dabryanus Dumeril can be tracked and monitored, achieving "non-contact" tracking of the behavior trajectory of the released Acipenser dabryanus Dumeril, avoiding damage to fish bodies in the tracking process, leading to reduced tracking costs and improved accuracy of overall tracking.

The invention discloses a primer for detecting a Yangtze River acipenser body weight character related SNP molecular marker. The primer is characterized by comprising an upstream primer and a downstream primer, the nucleotide sequence of the upstream primer is as shown in SEQ ID NO: 1, and the nucleotide sequence of the downstream primer is as shown in SEQ ID NO: 2. The method can be used for breeding Yangtze River sturgeon juveniles with body weight character advantages and selecting parents. The invention firstly provides an SNP site related to the body weight character of acipenser Yangtze River. The SNP site exists in a low-weight population in sexual mature acipenser dungryanus individuals, and the technology can provide technical support for protection of acipenser dungryanus.
