A kind of jellyfish short-term low temperature induction seedling cultivation method

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 an improved new method for cultivating seedlings of this kind of marine treasure of jellyfish, in particular to the temperature reduction treatment of the jellyfish polyp from the natural water temperature at any time, after a certain period of low temperature treatment, the temperature rises to promote its occurrence. Schizophrenia produces disc-shaped larvae in a short-term low temperature induced seedling cultivation method of jellyfish. technical background [0002] Jellyfish has high edible and medicinal value. It ranks among the eight "sea treasures" in my country. It has a unique taste and flavor. It is a popular seafood delicacy in East Asia and South Asia. The market has always been in short supply. The annual international trade volume can reach hundreds of millions of dollars. The people of our country have eaten jellyfish for thousands of years, and they are at the forefront of the world in the jellyfish aquacult...

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
