Problems solved by technology

[0002] Jellyfish is a sea treasure breeding species. The current problems in the cultivation of jellyfish seedlings are: the survival rate of jellyfish seedlings is low, and the breeding cycle is short, which makes the supply of large-scale jellyfish seedlings unavailable in the middle and late stages, which affects the quality and output of jellyfish.

Embodiment

[0025] The cultivation method of embodiment jellyfish seed

[0026] The method for cultivating jellyfish seedlings of the present invention uses polyps to release butterfly bodies as first-level jellyfish seedlings, and jellyfish seedlings whose umbrella diameter grows from 1-1.5 cm to 3-5 cm are used as second-level jellyfish seedlings for temporary cultivation. For seedlings, the jellyfish whose umbrella diameter grows to 10-20cm from 3-5cm is used as the third-level jellyfish to temporarily raise seedlings, and the cultivation method is as follows:

[0027] (1) The cultivation of first-class jellyfish temporary seedlings: the cultivation of polyps

[0028] The time for artificially cultivating polyps is from September to October. The fertilized eggs metamorphose into floating larvae after 6 to 8 hours, and the floating larvae are lively and rotate to the left. After 3 to 4 days, it metamorphoses into an early polyp larvae. The front end attaches to form a foot plate and h...

Abstract

The invention relates to a cultivation method of a rhopilema esculentum offspring seed. The cultivation method comprises the following steps: according to a model for gradually cultivating a rhopilema esculentum seedling, taking the stage from scyphistoma to butterfly-like body as a temporary first-class rhopilema esculentum culturing seedling, taking the rhopilema esculentum offspring seed with the shed diameter from 1-1.5cm to 3-5cm as a temporary second-class rhopilema esculentum culturing seedling, and taking the rhopilema esculentum with the shed diameter from 3-5cm to 10-20cm as a temporary third-class rhopilema esculentum culturing seedling. The cultivation method is characterized in that the temporary first-class rhopilema esculentum culturing seedling can provide the offspring seed to the temporary second-class rhopilema esculentum culturing seedling, the temporary second-class rhopilema esculentum culturing seedling can provide the offspring seed to the formed rhopilema esculentum culturing pond and the temporary third-class rhopilema esculentum culturing seedling, when the survival rate of the temporary second-class rhopilema esculentum culturing seedling in the formed rhopilema esculentum culturing pond is low, the temporary third-class rhopilema esculentum culturing seedling can replenish the offspring seed, and can provide the large-scale rhopilema esculentum seedling to the rhopilema esculentum forming culturing pond in the middle of August. In the cultivation method, according to the model for gradually cultivating the rhopilema esculentum seedling, the culturing cycle of the formed rhopilema esculentum is prolonged, multiple seedlings can be cultivated in one year, and the economic benefit of the rhopilema esculentum is improved in cultivation.

Description

technical field [0001] The invention relates to a method for cultivating jellyfish seedlings, in particular to a method for improving the survival rate of jellyfish seedlings and the yield of adult jellyfish seedlings by adopting a step-by-step cultivation model of jellyfish seedlings. Background technique [0002] Jellyfish is a sea treasure cultured species. The current problems in the cultivation of jellyfish seedlings are: the survival rate of jellyfish seedlings is low and the breeding cycle is short, which makes the supply of large-scale jellyfish seedlings unavailable in the middle and late stages, which affects the quality and output of jellyfish. Contents of the invention [0003] The purpose of the present invention is to provide a kind of cultivation method of jellyfish seed, by adopting jellyfish seedling step-by-step culture model, to improve the survival rate of jellyfish seed, guarantee the supply of the seedling whose umbrella diameter is 10-20cm in the midd...
