The red algae Asparagopsis sp. is produced in the waters of Taiwan's Pingtung Sea. The algae can be used for edible, medicinal, flavoring, feed additives, and can even be extracted into essential oils, with diversified development potential. At present, because the artificial commercial breeding technology has not been established, the production and quality of the wild algae are mainly collected seasonally for processing, and the yield and quality are relatively unstable. The whole goal of this project is to collect sea asparagus species in Pingtung, my country for domestication, and to establish the optimum temperature, light, salinity, and nutrient conditions through experiments, so as to establish sea asparagus artificial breeding technology. In this project year, the algae have been discovered in the waters of Ryukyu Township, Hengchun Township, Pingtung County, my country, and the algae body and habitat water samples have been collected for analysis. Because the algae have significant seasonal fluctuations, the summer high water temperature period has disappeared. Therefore, comparing the algae composition of the sea gate in the Ryukyu sea area in the late winter and early spring, and comparing it with the algae body collected in the Hengchun sea area, the results show that the main factors affecting should be temperature and light. The artificial domestication process needs to be stable. Adjust temperature, light, and various water quality conditions to ensure its survival and growth. The general composition analysis of algae is similar to that of Sarcodia sp.. It is a high-fiber food rich in minerals and protein and low in fat. In terms of important components, photosynthetic pigments The contents of phycobiliprotein and total phenols are also similar to those of Sarcodia sp., but the fatty acid composition is relatively poor. Subsequent cultivation conditions will continue to be tested to serve as the basis for the stable production of sea asparagus in the Pingtung waters.
