Problems solved by technology

[0006] Most of the patents related to jellyfish are the rough processing or finishing technology of various jellyfish foods. At present, only the patent with the application number 200410020827 involves the off-season seedling breeding technology of jellyfish seedling cultivation technology. This technology mainly preserves jellyfish polyp in low temperature , and then raise the temperature to promote the jellyfish to undergo transverse reproduction, which takes a long time, and the patent has been rejected

Embodiment Construction

[0017] see figure 1 , the present invention has developed a kind of jellyfish short-term low-temperature treatment seed cultivation method, takes the following steps:

[0018] The method is to prepare a sufficient number of robust jellyfish polyp seedlings at any time, gradually cool down from the natural water temperature to a certain low temperature condition, treat the jellyfish polyp at low temperature for a period of time, and then gradually heat up to the jellyfish transverse reproductive induction temperature, Induce the occurrence of jellyfish transverse reproduction, and then obtain jellyfish seedlings in batches. During the entire treatment period, management measures such as low light conditions, suitable aeration, timely water change, and reasonable feeding are adopted.

[0019] Implementation column 1

[0020] The low-temperature preservation temperature is 6°C, and the fluctuation range does not exceed 0.5°C; the polyp used is the polyp under the natural water t...

Abstract

The invention provides a jelly fish short-term low-temperature induction rearing method. The method is characterized in that: a strong jelly fish scyphistoma is prepared about a month before jelly fish breeding, is bred for a period at low temperature in an environment that natural water temperature is gradually cooled to low temperature, and then is heated to strobilation induction temperature; and operations of water changing, bait casting, air charge and lighting are carried out, so the jelly fish acetabular seedlings can be obtained in batch in short term. The jelly fish breeding method is not restricted by seasons, can breed the jelly fish acetabular larva in short term after the jelly scyphistoma is obtained, can shorten or avoid the sexual reproduction process of breeding to a certain extent, can improve the efficiency and benefit of jelly fish breeding, has concise process, lowers production cost, and is suitable for wide popularization.

Description

technical field [0001] The present invention relates to a new method for cultivating the rare species of jellyfish, especially the method of cooling the jellyfish polyp from the natural water temperature at any time, and after a certain period of low temperature treatment, then raising the temperature to promote its transversal A short-term low-temperature induced seedling cultivation method of jellyfish by fission reproduction to produce scalloped larvae. technical background [0002] Jellyfish has high edible and medicinal value. It is one of the eight "sea treasures" in my country. It has a unique taste and flavor. It is a popular seafood delicacy in East and South Asia. The market has always been in short supply. The annual international 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 histor...
