Abstract Korea has a long history of utilizing seaweeds, as the country has a high biodiversity of seaweeds. The abundance and composition of seaweed species have changed over the past decades due to climate change and anthropogenic influences. Some species showed a significant extension of their distribution range to the north while some species declined. Some areas have even become barren ground. Korea has put extensive effort into restoring the seaweed resources in these deforested areas. Korea is one of the most advanced countries in the World in terms of seaweed aquaculture. However, the aquacultured species are mostly limited to three genera, Saccharina, Undaria and Pyropia/Porphyra, which represent 96% of the entire seaweed production in the country. Korea has developed highly advanced cultivation technologies as well as various cultivars using breeding and hybridization technologies for these species. There has also been considerable effort in developing environmentally sustainable aquaculture systems using seaweed cultivation (e. g. integrated multi-trophic aquaculture, nutrient bioextraction and biofloc). This study discusses the current status and challenges of the above mentioned topics in detail. In addition, the present study encourages South and North Korean scientists to collaborate in the study of seaweed resources at the border of these two countries.

韩国海藻资源

摘要 韩国利用海藻有着悠久的历史，因为该国海藻的生物多样性很高。由于气候变化和人为影响，海藻物种的丰度和组成在过去几十年中发生了变化。一些物种的分布范围向北显着扩展，而一些物种则下降。一些地区甚至变成了贫瘠之地。韩国为恢复这些森林砍伐地区的海藻资源付出了大量努力。韩国是世界上海藻养殖最先进的国家之一。然而，水产养殖品种大多限于糖精、裙带菜和紫菜/紫菜三个属，占该国整个海藻产量的96%。韩国已经开发了高度先进的栽培技术以及使用这些物种的育种和杂交技术的各种栽培品种。在开发使用海藻养殖的环境可持续水产养殖系统（例如综合多营养水产养殖、养分生物提取和生物絮团）方面也付出了相当大的努力。本研究详细讨论了上述主题的现状和挑战。此外，本研究鼓励韩国和朝鲜科学家合作研究两国边境的海藻资源。养分生物提取和生物絮团）。本研究详细讨论了上述主题的现状和挑战。此外，本研究鼓励韩国和朝鲜科学家合作研究两国边境的海藻资源。养分生物提取和生物絮团）。本研究详细讨论了上述主题的现状和挑战。此外，本研究鼓励韩国和朝鲜科学家合作研究两国边境的海藻资源。
