Embodiment Construction

[0036] A method for long-term preservation of jellyfish polyps at low temperature,

[0037] Precipitate seawater for 2-3 days; filter the precipitated seawater with sand; then disinfect and sterilize the filtered seawater with chlorine dioxide; finally adjust the pH value of the seawater and the salinity of the water body, the preferred pH is 7.5 -8.5, the salinity of seawater is 18-30‰, and then directionally cultivate beneficial bacteria to supplement the seawater. The treated seawater is injected into the indoor culture pool and the storage pool of the storage room respectively, and the bacteria are supplemented and oxygenated at the same time. Select the seedling plate attached to the jellyfish polyp that develops to 8-16 tentacles that is obtained by breeding, put it into the indoor culture pond of step 1 for temporary cultivation, and screen out strong and vigorous jellyfish polyp; Vigorous jellyfish polyp seedling plates are transferred to the pool in the storage room f...

Abstract

The invention discloses a low-temperature long-term breed conservation method for jellyfish scyphistoma. The low-temperature long-term breed conservation method is mainly characterized in that the temperature of indoor water and the feeding time period are adjusted according to the outdoor temperature, and the development process of the jellyfish scyphistoma is delayed by adopting a method of manually controlling the temperature of water for breeding. According to the method, a special refrigeration storage room for jellyfish scyphistoma conservation is adopted, the jellyfish scyphistoma is kept in a low-water-temperature environment for a long time, and seawater for breeding is subjected to technical treatment such as precipitation, filtration, disinfection and bacterium supplementation. Besides, the whole storage chamber has heat preservation and heat insulation functions, heat preservation layers are applied to the top and the wall body part by spraying, heat insulation and heat preservation materials are arranged in the middle of a pool body for storing water during construction, and resin glass fibers are sprayed to the inner wall of the pool body, so that the stability of the temperature in the storage room can be guaranteed, and the stability of the quality of seawater in the pool body can be guaranteed. According to the method, the technical problem that long-term breed conservation of the jellyfish scyphistoma cannot be realized is solved, full-year production of jellyfish seedlings is achieved, jellyfish farmers can breed the jellyfish seedlings in a multi-crop mode, the requirements of the jellyfish seedlings are met, and the economic benefits of jellyfish breeding are improved.

Description

technical field [0001] The invention relates to the technical field of jellyfish species conservation, in particular to a low-temperature long-term conservation method for jellyfish polyps. Background technique [0002] The jellyfish belongs to the class of jellyfish, the order of jellyfish, the order of jellyfish, the family of jellyfish, and the genus jellyfish. It is a large-scale edible jellyfish that lives in plankton. It is widely distributed in my country, from Liaoning in the north to Hainan in the south. The traces of survival, especially in the coast of Zhejiang Province, have the most production, but due to human activities destroying its habitat, coupled with long-term overfishing, its resources have declined sharply. Jellyfish is delicious and nutritious. It is one of the main aquatic products in my country. At present, there are only 4 kinds of jellyfish in the world, and my country accounts for 3 kinds. Jellyfish has high edible and medicinal value. It is one ...
