Alternate culture method of sargassum thunbergii and kelp

Abstract

The invention provides an alternate culture method of sargassum thunbergii and kelp. The method is characterized in that the alternate culture of kelp and sargassum thunbergii is carried out in the same aquaculture waters in the north; the kelp is cultivated from November in the current year to June in the next year, and the sargassum thunbergii is cultivated from April to July; the growth conditions of the sargassum thunbergii are improved through vacant kelp cultivating facilities after the kelp is harvested, so as to improve the cultivation and maintenance conditions of the sargassum thunbergii, and promote the growth of the sargassum thunbergii. The alternate culture of kelp and sargassum thunbergii is realized in the aquaculture waters in the north, i.e. the growth conditions of the sargassum thunbergii are improved in the quick growth period of the sargassum thunbergii with the help of vacant raft frames after the kelp is harvested, so as to promote the growth of the sargassum thunbergii. Compared with the original aquaculture method, the alternate culture method of sargassum thunbergii and kelp has two main advantages that (1) sargassum thunbergii aquaculture facilities are saved and the aquaculture cost is reduced; (2) waters resources are fully utilized, meanwhile, the sargassum thunbergii aquaculture conditions are improved, the ecological and economic benefits are increased, so as to achieve the purposes of making full use of the waters resources and improving the aquaculture value of seaweed.

Description

technical field [0001] The invention relates to seaweed cultivation technology, in particular to a method for carrying out sagera and seaweed cultivation in rotation in northern seaweed cultivation areas. Background technique [0002] Kelp is a kind of large brown algae with high economic value. Our country’s kelp culture has developed into a large-scale industry. From Liaoning to the coast of Guangdong, the output accounts for about 50% of the world’s seaweed, ranking first in the world and becoming my country’s aquaculture industry. pillar industry. The kelp breeding time is generally from November to June of the following year, and the harvest starts from April and ends in June. After that, the rafts and sea area resources for cultivating kelp were idle, causing a lot of waste. [0003] Sargassum is one of the genus Sargassum, and it is one of the important economic seaweed resources in my country. It is mainly distributed in Liaoning to Fujian coastal areas. Sargassum h...

Problems solved by technology

There are no falling stones at both ends of the seedling rope, so the whole sargassum floats on the sea surface, and the roots of the sargassum rot and fall off due to too much light. In daily maintenance, it is only artificially washed, and the miscellaneous algae and hook shrimp are not easy to clean. Cleared, affecting the production of sargassum
