Cultivation method of rhopilema esculentum offspring seed

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...
