Method for collecting high-quality patinopecten yessoensis seminal fluid

The invention discloses a method for collecting high-quality patinopecten yessoensis seminal fluid, and belongs to the technical field of marine organisms. The method comprises the first step of selecting, temporally rearing and maturing the high-quality male patinopecten yessoensis, the second step of luring the male patinopecten yessoensis to discharge the seminal fluid and collecting the seminal fluid many times, and the third step of detecting the quality of the collected seminal fluid. The collecting method is simple and easy to operate, the parent patinopecten yessoensis cannot be hurt, the seminal fluid can be repeatedly collected, and the collected seminal fluid can be stored for a long time. It is only required to understand the genital glands of the scallops and the anatomical structures of the excretory organs and accurately recognize the nephridium and the nephridiopore when the seminal fluid is collected. The seminal liquid collected from one ordinary male patinopecten yessoensis each time can be 0.5-1.5 ml. Under the situations that the temperature is controlled and the sufficient nutrient is guaranteed, the gonad can be promoted to be mature and discharge the seminal fluid many times, and the seminal fluid of each patinopecten yessoensis can be repeatedly collected two to four times till the March or April.
