Method for rapid asexual propagation of aurelia aurita

Abstract

The invention relates to a method for rapid asexual propagation of an aurelia aurita, which comprises the following steps of: enabling a certain density of aurelia aurita scyphistomae attached to a polyethylene corrugated plate to be propagated rapidly through gemmatio under an appropriate condition, and enabling the scyphistomae to reach a certain density within a short time; transplanting the scyphistomae on the original corrugated plate to other clean corrugated plates according to the density of 0.5-0.7 per square centimeter; adding scyphistomae nutrient solution; enabling the scyphistomae to be propagated rapidly on the new corrugated plate under an appropriate condition after the scyphistomae is attached to the new corrugated plate; and carrying out strobilation on the scyphistomae through temperature control after the scyphistomae reaches a certain number so as to generate large number of aurelia aurita ephyrae and medusas. Due to the adoption of the method, a large numberof aurelia aurita scyphistomae, ephyrae and medusas which have high activity can be obtained without aurelia aurita adults. The method is rapid, simple and economical, and is suitable for obtaining an aurelia aurita material under a simple experiment condition.

Description

Technical field: [0001] The invention belongs to the breeding technology of coelenterates, and in particular relates to a method for rapid asexual reproduction of moon jellyfish. Background technique: [0002] Moon jellyfish is a large jellyfish widely distributed in various sea areas of the world. In the past 100 years, foreign scholars have conducted extensive research on it. It is a good experimental material for biology teaching and scientific research. In textbooks, almost all the jellyfish are used as representatives of the coelenterate phylum and the class jellyfish. How to obtain a large number of sea moon jellyfish in a stable manner? At present, most of the jellyfish materials obtained at home and abroad are the jellyfish body of the domesticated jellyfish. The source of the material is extremely unstable and limited by the season. Another method is to produce through the transverse reproduction of polyps kept in the laboratory.

How to obtain a large number of sea moon jellyfish in a stable manner? At present, most of the jellyfish materials obtained at home and abroad are the jellyfish body of the domesticated jellyfish. The source of the material is extremely unstable and limited by the season. Another method is to produce through the transverse reproduction of polyps kept in the laboratory. Discs and polyps are mainly obtained through sexual reproduction of the moon jellyfish. However, the process of metamorphosis of the moon jellyfish from nurturing to sexual maturity to producing floating larvae is extremely cumbersome, and the mother body of the moon jellyfish In the breeding process, the amount of seawater is large, and the requirements for the breeding environment are relatively harsh. It is difficult for ordinary laboratories to meet its growth conditions.
