Problems solved by technology

Most of the patents related to jellyfish are the rough processing or finishing technology of various jellyfish foods. At present, there is only the off-season breeding technology of jellyfish. This technology is mainly to meet the needs of jellyfish seed production in different regions and seasons, and does not involve jellyfish polyps. New Year Childcare and other related methods

Embodiment Construction

[0014] see figure 1 , the present invention has developed a kind of jellyfish polyp overyear conservation asexual reproduction method, takes the following steps:

[0015] The method is to prepare a sufficient number of jellyfish polyp seedlings at the beginning of summer every year when the normal jellyfish seedlings are cultivated, and then keep them under low temperature conditions, light them, feed them, inflate them in a small amount, change water, and asexually reproduce and develop.

[0016] Implementation column 1

[0017] The cryopreservation temperature is 6°C, and the fluctuation range does not exceed 0.5°C; the polyps used can directly adopt the polyps under the natural water temperature of 6°C, or use the polyps that have undergone transversal reproduction. The water temperature is 19°C, and the temperature should be gradually and slowly lowered to 6°C for conservation, with a daily cooling rate of less than 1.2°C.

[0018] The light is at 3500 lx, the salinity r...

Abstract

The invention provides a hibernating conservation asexual reproduction method for jellyfish hydranth. The method is characterized in that when normal cultivation of young jellyfish is finished in early summer every year, an enough quantity of jellyfish intestinal-shape young fingerlings are purchased and subjected to conservation, illumination, feeding, trace-amount inflation, water changing, asexual reproduction and development under the condition of low temperature. The method improves the efficiency and benefit of cultivating jellyfish fingerlings by reducing or avoiding a sexual reproduction process of fingerling cultivation, has a simple structure, reduces production cost, and is suitable for extensive popularization.

Description

technical field [0001] The invention relates to a method for cultivating and improving the genetic breeding of jellyfish seedlings, in particular to a method for keeping jellyfish polyps over the years under certain environmental conditions and then inducing their transverse fission to produce jellyfish disc larvae for asexual reproduction. technical background [0002] Jellyfish is one of the eight "sea treasures" and has high edible and medicinal value. It is a popular seafood delicacy in East Asia and South Asia. The market has always been in short supply, and its annual trade volume can reach hundreds of millions of dollars. Chinese people have eaten jellyfish for thousands of years, and they are at the forefront of the world in terms of jellyfish breeding. Relevant scholars figured out the life history of jellyfish in the 1980s, and achieved the success of jellyfish industrial seedling cultivation in the 1990s, and then carried out the release and proliferation of jelly...
