A kind of indoor fully artificial breeding method of jellyfish

Abstract

The invention belongs to the field of aquatic animal breeding and particularly relates to an indoor totally-artificial jellyfish breeding method. The indoor totally-artificial jellyfish breeding method is characterized in that high-quality jellyfish hydroid polyp bodies stored under a low temperature are stimulated so that strobilation of the high-quality jellyfish hydroid polyp bodies can be formed and ephyrae can be generated; all environmental factors are controlled to make the ephyrae grow into adult jellyfishes inside a room. After the jellyfishes grow into the sexual maturity stage, gonads of the jellyfishes are made mature and oviposition and fertilization are carried out through an artificial inducing method, and finally zygotes grow into the ephyrae and indoor totally-artificial jellyfish breeding is completed. A large number of high-quality jellyfish hydroid polyp bodies can be once supplied according to the indoor totally-artificial jellyfish breeding method, the defects that hydroid polyp body supplement rate is low because podocyst breeding efficiency is low and the total number of the hydroid polyp bodies is continuously reduced because a large number of hydroid polyp bodies are separated from boards are overcome, and technical support is provided for storage of high-quality jellyfish seeds.

Description

technical field [0001] The invention belongs to the field of aquatic animal breeding, and in particular relates to an indoor fully artificial breeding method for jellyfish. Background technique [0002] The jellyfish (Rhopilema esculenta Kishinouye 1891) belongs to the class of Jellyfish, the order of the Rhizophyllum, the family of the Rhizophyllidae, and the genus Jellyfish. It is a large-scale near-shore edible jellyfish that lives in plankton. It is an important fishing target, and its output accounts for more than 90% of all edible jellyfish. In recent years, due to the destruction of its habitat by human activities, coupled with long-term overfishing, its resources have declined sharply. With the development of my country's jellyfish artificial breeding industry, more and more problems are presented in front of our country's scientific and technological workers, how to preserve high-quality seedlings for a long time is one of them. Initially, the breeding mode of jel...

AI Technical Summary

Problems solved by technology

Initially, the breeding mode of jellyfish seedlings in my country was to harvest wild stings every autumn, and indoor breeding to obtain polyps for use in the next year. However, after the seedlings were completed, the number of remaining polyps decreased sharply due to reasons such as de-boarding and natural death, and there was no production Therefore, it is impossible to preserve the high-quality germplasm resources of jellyfish for a long time

In recent years, relevant scientists have used long-term low-temperature environment to preserve polyps and achieved good results. However, due to the low replenishment rate of polyps and the high mortality rate caused by a large number of off-boards, the overall number of seedlings has been continuously reduced.
