Abstract Tanzania is endowed with a rich biodiversity of seaweed species that grow naturally in its oligotrophic waters of the Western Indian Ocean. Most of these species are unexploited. Only two red seaweeds Eucheuma and Kappaphycus have been studied for commercial farming and the industrial production is based on these species. Another genus of red seaweed, Gracilaria, has been studied and experimented upon for potential farming while others such as the green Ulva, the red Hypnea and the brown Sargassum have been mentioned as potential species for farming. Farming technology used to cultivate the two commercial species is the shallow water off-bottom technology which is badly affected by the increase in surface seawater temperatures (climate change), causing massive die-backs and decreased seaweed production. Some deeper-water farming technologies have been developed but only tubular nets show promise and have been piloted. A number of opportunities exist in seaweed farming, which can be used to advance the industry. The future of the seaweed industry in Tanzania will depend on using the existing opportunities, including utilising the seaweed species already studied, exploring the potential of other seaweed species for farming, development of deeper-water farming technologies, added-value, and ensuring availability of good quality seed material.

坦桑尼亚海藻资源：现状、潜在种类、挑战和发展潜力

摘要 坦桑尼亚拥有丰富的海藻物种生物多样性，这些海藻物种自然生长在西印度洋的贫营养水域。大多数这些物种是未开发的。只有两种红海藻 Eucheuma 和 Kappaphycus 被研究用于商业养殖，工业生产基于这些物种。另一个红海藻属，江蓠属，已被研究和试验用于潜在的养殖，而其他如绿色石莼、红色海藻和棕色马尾藻被认为是潜在的养殖品种。用于培育这两种商业物种的养殖技术是浅水离底技术，该技术受到表层海水温度升高（气候变化）的严重影响，导致大量枯死和海藻产量下降。一些深水养殖技术已经开发出来，但只有管状网显示出前景并进行了试点。海藻养殖存在许多机会，可用于推动该行业的发展。坦桑尼亚海藻产业的未来将取决于利用现有的机会，包括利用已经研究过的海藻品种、探索其他海藻品种的养殖潜力、开发深水养殖技术、附加值以及确保可利用性优质种子材料。
