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.

Benefits of technology

This patented technology allows fishermen to grow large numbers of blue-green clams on their own seafloor by rotating them around an oceanic tank containing water called salinity during different periods over time. By doing this, they have more space available than before but still benefit from these natural resource sources like sunlight or freshwater. Additionally, when there're no rain at all, the plants will be able to take up enough land within one day without being affected with any harmful consequences due to lack of food supply. Overall, this innovation improves both marine ecosystem management (SEM) and increasing biodiversity while also reducing cost compared to traditional methods.
