Problems solved by technology

In July 2009, the sea moon jellyfish broke out on the coast of Qingdao, my country, which caused the blockage of the cooling system of the power plant and seriously affected the power supply; the sea moon jellyfish outbreak was reported in Yantai, Weihai, Qinhuangdao and other coastal waters of my country, seriously affecting coastal power generation normal operation of the plant
[0005] At present, there are no reports or patent applications on the prevention and control methods for the outbreak of the moon jellyfish disaster

Embodiment 1

[0026] Embodiment 1: The determination of the killing activity of tea saponin on the sculpture of the sea moon jellyfish

[0027] The jellyfish larvae used in the present invention come from the Yantai Coastal Zone Research Institute of the Chinese Academy of Sciences, and the scalloped larvae of the jellyfish are obtained through a temperature-inducing method. Set 0mg / L, 0.1mg / L, 0.5mg / L, 1mg / L, 2mg / L, 3mg / L, 4mg / L, 5mg / L, 10mg / L, 50mg / L, a total of 10 tea saponin concentration treatments group, the test solution was prepared with 0.22um filtered seawater. During the experiment, put the sputum larvae of jellyfish into a 24-well deep well plate, add 8 sauculus larvae of jellyfish for each treatment, and add 10ml of tea saponin solution to each hole. Three replicates were set up for each treatment, cultured in an incubator at 16°C, and the number of dead larvae of S. jellyfish was observed and recorded at 24h and 48h. The median lethal concentration of tea saponin on the scle...

Embodiment 2

[0029] Embodiment 2: Determination of the killing activity of tea saponin on jellyfish polyps

[0030] The jellyfish polyps used in the present invention come from Yantai Institute of Coastal Zone, Chinese Academy of Sciences. Set 0mg / L, 0.1mg / L, 0.5mg / L, 1mg / L, 2mg / L, 3mg / L, 4mg / L, 5mg / L, 10mg / L, 50mg / L, a total of 10 tea saponin concentration treatments group, the test solution was prepared with 0.22um filtered seawater. During the experiment, the larvae of the jellyfish were put into a 24-well deep-well plate, and 8 larvae of the jellyfish were added to each treatment, and 10 ml of the tea saponin solution for testing was added to each well. Three replicates were set up for each treatment, cultured in an incubator at 16°C, and the number of dead larvae of jellyfish polyp was observed and recorded at 24h and 48h. The median lethal concentration of tea saponin on polyp larvae was calculated using the probability unit method (Probit).

[0031] The results showed that, at 48...

Abstract

The invention relates to the field of biological control, and in particular relates to application of tea saponin in prevention and control of aurelia. The application of the tea saponin in the prevention and control of the aurelia is namely application of the tea saponin in preparation of an inhibitor used for preventing and controlling the aurelia. The tea saponin related in the invention is from natural ingredients obtained through extraction of seeds, stems and leaves of a tea tree in theaceae, is easily degradable in the environment, meets the ecological safety requirement and is a natural non-ionic surface active agent. Toxicity tests of the tea saponin on aurelia ephyra larvae and scyphistoma prove that the tea saponin has extremely strong killing toxicity on the aurelia ephyra larvae and scyphistoma and then can be applied to prevention and control of influence of an aurelia disaster on a coastal power plant and a marine aquaculture industry.

Description

technical field [0001] The invention relates to the field of biological control, in particular to an application of tea saponin in preventing and controlling moon jellyfish. Background technique [0002] Aurelia aurita belongs to the phylum Cnidaria, the class Scyphozoa, the order Semaeostomeae, the family Ulmaridae, and the genus Aurelia. The moon jellyfish is mainly distributed in the coastal waters of the Yellow Sea and Bohai Sea in my country, and belongs to the dominant species of large jellyfish in my country's waters. [0003] In recent years, the moon jellyfish outbreak has brought many disastrous effects to the production activities in the coastal zone, and has become a coastal ecological disaster event. The outbreak of sea jellyfish will affect the normal operation of coastal power plants. In July 2009, the sea moon jellyfish broke out on the coast of Qingdao, my country, which caused the blockage of the cooling system of the power plant and seriously affected th...
