在澎湖海域養殖中國半葉馬尾藻其種苗來源是利用受精卵發育而來之幼苗。從4至5月於天然環境採收中國半葉馬尾藻生殖托，並以自然光照或光週期12L：12D，溫度為20或25 °C蓄養在室內的500L水槽。培育在實驗室內300L水槽的馬尾藻生殖托，會釋放出受精卵後並成功地發育為胚，並且大量繁殖發芽。而初生幼苗將成為移植到1-3米深度海藻床的人工種苗。低溫培養貨櫃所進行之馬尾藻苗渡夏試驗，已可有效的維持藻苗存活，而低溫渡夏操作過程初期（6-8月），光照週期以L:D=12:12可讓藻苗有最高生長速率，到後期（9-10月）則各光照週期之間的處理對於藻苗成長沒有差異。由結果得知養殖全年生的中國半葉馬尾藻是有可能持續發展的。

研究報告摘要(英) Cultivation of brown alga Sargassum hemiphyllum var. chinense in the waters of Penghusea depends on zygote-derived seedlings. Field-collected receptacles of Sargassumhemiphyllum var. chinense were cultivated in 500-L indoor tanks from April to May atambient daylength or in a constant L:D regime of 12L:12D, both at 20 or 25 °C. Embryo were successfully derived from the released fertilized eggs for mass propagation of the germlingsin 300-L indoor tanks in a laboratory. These primary germlings were outplanted at a depth of 1-3 m in artificial seaweed beds as a source. The low-temperature over-summer cultivation manipulation (OSCM) can effectively ensure the survival of the juveniles. During the early stage of the OSCM (June-August), the juveniles under the photoperiod of light/ dark ratio at 12hr/ 12hr, showed significantly higher growth rates than the other two photoperiod control situations. However, the juveniles of all photoperiod controlled situations showed noe significantly variation during the late stage of OSCM (September-October). These results may support the development of sustainable, year-round Sargassum hemiphyllum var. chinense farming
