Pest and disease outbreaks have significant impacts on the livelihoods of seaweed farmers each year, particularly in low- to middle-income countries around the world. Commercial seaweed farming of the red carrageenophytes, Eucheuma denticulatum, Kappaphycus alvarezii and Kappaphycus striatus, in Tanzania was established in 1989. The impacts of pests and diseases on the local seaweed industry had serious implications for the environment, society, local culture and human health. The industry was initially characterised by growth, but since 2002 has been severely limited due to pest and disease outbreaks, exacerbated by the effects of climate change. This paper identifies existing biosecurity frameworks in Tanzanian legislation and policies in order to assess their content regarding the management of pests and diseases in the seaweed industry. A total of thirteen frameworks were identified and analysed for their general biosecurity scope and inclusion of specific risks. Of the thirteen, only four were legally binding, and only four were identified to be applicable to the seaweed industry. National frameworks were predominantly designed to support finfish aquaculture; therefore, national authorities lack the expertise, experience and scientific basis on biosecurity issues in seaweed industry compared with other aquatic commercial commodities to identify and mitigate the risks from pest and disease outbreaks in the seaweed farming industry. Recommendations are provided to assist regulators in establishing biosecurity policies, which either explicitly include or are specifically designed, to support the Tanzanian seaweed industry. This analysis reveals where biosecurity capacity can be developed to support a sustainable and economically productive national seaweed farming industry.

虫害和疾病的爆发每年都对海藻养殖者的生计产生重大影响，特别是在世界范围内的中低收入国家。红色角叉菜，Eucheuma denticulatum，Kappaphycus alvarezii和Kappaphycus striatus的商业海藻养殖，在坦桑尼亚成立于1989年。病虫害对当地海藻产业的影响对环境，社会，当地文化和人类健康产生了严重影响。该行业最初以增长为特征，但自2002年以来，由于病虫害暴发而受到严重限制，气候变化的影响加剧了该行业。本文确定了坦桑尼亚立法和政策中现有的生物安全框架，以评估其在海藻行业中对害虫和疾病进行管理的内容。总共确定了13个框架并对其总体生物安全范围和特定风险进行了分析。在13个中，只有4个具有法律约束力，并且只有4个被确定适用于海藻产业。国家框架的主要设计目的是支持有鳍水产养殖；因此，与其他水生商业商品相比，国家主管部门在海藻产业生物安全问题方面缺乏专门知识，经验和科学依据，无法确定和减轻海藻养殖业中病虫害暴发的风险。提供了一些建议，以帮助监管机构建立明确支持或明确设计的生物安全政策，以支持坦桑尼亚的海藻产业。该分析揭示了可以在何处开发生物安全能力，以支持可持续和经济生产的国家海藻养殖业。与其他水生商业商品相比，在海藻产业中具有生物安全问题的经验和科学依据，以识别和减轻海藻养殖业中病虫害暴发的风险。提供了一些建议，以帮助监管机构建立明确支持或明确设计的生物安全政策，以支持坦桑尼亚的海藻产业。该分析揭示了可以在何处开发生物安全能力，以支持可持续和经济生产的国家海藻养殖业。与其他水生商业商品相比，在海藻产业中具有生物安全问题的经验和科学依据，以识别和减轻海藻养殖业中病虫害暴发的风险。提供了一些建议，以帮助监管机构建立明确支持或明确设计的生物安全政策，以支持坦桑尼亚的海藻产业。该分析揭示了可以在何处开发生物安全能力，以支持可持续和经济生产的国家海藻养殖业。明确包括或专门设计用于支持坦桑尼亚海藻产业的产品。该分析揭示了可以在何处开发生物安全能力，以支持可持续和经济生产的国家海藻养殖业。明确包括或专门设计用于支持坦桑尼亚海藻产业的产品。该分析揭示了可以在何处开发生物安全能力，以支持可持续和经济生产的国家海藻养殖业。
