Abstract

The commercial use of kelp continues to gain interest worldwide. While in some East Asian countries kelp farming has a long history, the kelp industry in South Africa is based on harvesting of kelp from natural kelp forests or by beach-cast collection. This study examined the potential for kelp aquaculture on South Africa’s west coast, focusing on the three indigenous species of kelp, Ecklonia maxima, Laminaria pallida and Macrocystis pyrifera. Geospatial analysis was used to identify and assess nine potentially suitable areas for kelp farming, based on natural habitat conditions, and examination of potential conflicts with other users and enabling land-use factors. An assessment of the market, technical and financial aspects of a kelp farming opportunity indicated that a 4 ha kelp farm, with longlines producing 750 to 1,000 t of fresh kelp per annum, could be viable as an integrated aquaculture activity adjacent to an existing mussel or oyster farm. We recommend a detailed feasibility study for kelp aquaculture in South Africa, with market and technical research, and financial modelling. Current seaweed industry legislation is mostly concerned with the wild resource, and there is a need for specific policies relating to seaweed aquaculture to facilitate growth of the industry.

南非西海岸海带水产养殖的考虑因素：地理空间分析和研究意义

海带的商业利用在全球范围内继续受到关注。在一些东亚国家，海带养殖历史悠久，而南非的海带产业则以从天然海带林或海滩采集海带为主。本研究考察了南非西海岸海带水产养殖的潜力，重点关注三种本地海带物种：Ecklonia maxima、Laminaria pallida和Macrocystis pyrifera。根据自然栖息地条件、与其他用户的潜在冲突以及有利的土地使用因素，利用地理空间分析确定并评估了九个可能适合海带养殖的区域。对海带养殖机会的市场、技术和财务方面的评估表明，在现有的贻贝或牡蛎养殖场附近建立一个 4 公顷的海带养殖场，使用延绳每年生产 750 到 1,000 吨新鲜海带，作为一项综合水产养殖活动是可行的。我们建议对南非的海带水产养殖进行详细的可行性研究，包括市场和技术研究以及财务建模。当前的海藻产业立法主要涉及野生资源，需要制定与海藻养殖相关的具体政策，以促进该产业的发展。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
