Problems solved by technology

Under the original breeding method, the size of the moon jellyfish is uncontrollable, and the development of the body shape is random. Some of the same batch of bred moon jellyfish grow into a disc shape, and some grow into a mushroom shape. The product specifications are different. Stablize

specific Embodiment approach 1

[0015] The specific operation includes the following steps:

[0016] 1. Cultivation of moon jellyfish under normal salinity. The moon jellyfish grows to about 3 cm at a normal breeding salinity of 30. It has relatively strong vitality and no individual damage. At this time, most of the moon jellyfish are thick round cakes, and there is no big difference in size.

[0017] 2. Change the salinity of seawater in groups, thereby changing the shape of the moon jellyfish. It is mainly divided into two groups, one with increasing salinity and one with decreased salinity. When the salinity changes, it should be done slowly, and the salinity should be increased or decreased by 1-2 per day. The lower the salinity, the smaller the thickness of the umbrella body of the moon jellyfish, and the higher the salinity, the greater the thickness of the umbrella body of the moon jellyfish. In order to produce disc-shaped moon jellyfish, reduce the salinity of the seawater where the moon jellyfis...

Abstract

The invention discloses a method for controlling physique of aurelia aurita by using salinity. The method comprises the following steps of: culture of aurelia aurita under normal conditions, culture of the aurelia aurita after the salinity is changed and culture after the physique of the aurelia aurita is changed. The method controls the physique of the aurelia aurita by controlling the salinity of seawater for culturing the aurelia aurita according to the life habit and the growth characteristic of the aurelia aurita. By changing the salinity, the physique of the aurelia aurita can be manually controlled, and the aurelia aurita of various physiques can be directionally produced to meet the demands of different customers.

Description

technical field [0001] The invention relates to marine biological technology, and relates to a method for controlling the shape of a jellyfish by using salinity. Background technique [0002] Moon jellyfish, belonging to the coelenterate phylum, the class of the pot jellyfish, and the order of the jellyfish, Taiwan is also known as the UFO jellyfish. It is distributed in all oceans of the world. On the coast of Yantai, Shandong, my country, groups of them can be found in July and August. Moon jellyfish. The umbrella body of the moon jellyfish is colorless and transparent, disc-shaped, 98% of the body is water, mainly composed of the umbrella body and the mouth and wrist. There are four horseshoe-shaped stomach sacs in the middle of the umbrella body, and the umbrella body is covered with net-like radial tubes, and there is a circle of slender tentacles on the edge of the umbrella body. There are four ribbon-shaped wrists under the umbrella body. The average lifespan of the...
