Intermediate rearing method for Sargassum thunbergii Kuntze seedlings

Abstract

The invention relates to an intermediate rearing method for Sargassum thunbergii Kuntze seedlings, which is characterized in that: breeding waste water from industrial greenhouse breeding performed by pumping underground seawater is used for the intermediate rearing of the Sargassum thunbergii Kuntze seedlings; and filter-feeding shellfish and / or prawns are cultured in a culture pond. By using breeding waste water from industrial greenhouse breeding performed by pumping underground seawater for culturing Sargassum thunbergii Kuntze seedlings, the invention provides an intermediate rearing method for Sargassum thunbergii Kuntze seedlings in northern China. In the method disclosed by invention, the overwintering and aestivating problems in the propagation process of the Sargassum thunbergii Kuntze seedlings are successfully solved by using the energy of breeding waste water, and the Sargassum thunbergii Kuntze seedlings grow fast constantly; and the Sargassum thunbergii Kuntze can absorb organic waste in the breeding waste water, so that the waste water from the industrial greenhouse breeding is recycled, and ocean environment is protected. Meanwhile, a large amount rearing and management cost is saved by using the inhibition effect of the filter-feeding shellfish and prawns on the enemy organisms of the Sargassum thunbergii Kuntze seedlings in an early growing stage.

Description

technical field [0001] The invention belongs to the technical field of algae seed cultivation, and in particular relates to a method for intermediate cultivation of sargassum seedlings, that is, the intermediate cultivation of sargassum seedlings is carried out by using the culture wastewater in industrial greenhouses. Background technique [0002] Sargassum thunbergii belongs to the Phaeophyta, Enzophyta, Fucusaceae, Sargassumaceae, and Sargassum genus. It is a common wild macroalgae in the coastal areas of my country. Sargassum has a wide distribution range in my country, from the Liaodong Peninsula in the north to the Leizhou Peninsula in the south, and its traces are all over Liaoning, Shandong, Jiangsu, Zhejiang, Fujian, Guangdong and other provinces. As a high-quality bait for sea cucumbers and abalones, with the development of sea cucumber and abalone aquaculture, naturally growing sargassum has been harvested and utilized in large quantities, so that wild sargassum r...

Problems solved by technology

At present, aquaculture enterprises generally discharge the aquaculture wastewater directly to the outside, which not only causes a waste of energy, but also causes environmental pollution due to the large amount of organic waste contained in the aquaculture wastewater.
