摘要
随着对海藻生物量和高品质产品需求的增加,迫切需要一种更高产、更可持续的栽培系统。深层海水(DSW)富含无机营养物质,未受污染,具有低温稳定性。利用深层海水的小型工业已经建立,深层海水被用于瓶装饮用水、水产养殖、农业、化妆品、医药、食品和发电,所有这些都带来了可观的经济效益。帝汶河还被用于海藻养殖,其高浓度的营养成分提高了生物量产量和生化成分,同时减少了肥料支出。海洋热能转换(OTEC)是一种新兴的可再生能源生产技术。通过冷的帝斯曼海水和暖的表层海水之间的温差汲取的帝斯曼海水产生的能量可用于多种用途,包括海藻养殖。在温暖的热带地区,冷的潮间带可以用来调节海水温度,从而将温带高价值海藻的生长范围扩大到热带地区。马来西亚已被确定为适合发展 OTEC 的国家,尤其是沙巴州。马来西亚和日本之间正在进行的 OTEC 研究项目包括研究通过养殖鲍鱼和海藻从 OTEC DSW 创造价值。现在是全面审查利用帝斯曼海藻养殖的优势,以及如何将这一创新技术与 OTEC 系统相结合,为这两个行业提供增值产品和收入的时候了,这两个行业都是新兴蓝色经济的重要组成部分。
Sustainable high-quality seaweed production from deep seawater
The increase in the demand for seaweed biomass and high-quality products has created an urgent need for a more productive and sustainable cultivation system. Deep seawater (DSW) is rich in inorganic nutrients, unpolluted, and has low-temperature stability. Small-scale industries utilising DSW have been established, with DSW being employed for bottled drinking water, aquaculture, agriculture, cosmetics, medicine, food, and power generation—all contributing to substantial economic benefits. DSW has also been used for seaweed farming, where its high nutrient levels have increased biomass yield and biochemical composition while reducing fertiliser expenditures. Ocean thermal energy conversion (OTEC) is an emerging technology for renewable energy production. The DSW drawn up to generate energy through the temperature difference between the cold DSW and the warm surface seawater can be used for diverse applications, including seaweed cultivation. In warm tropical regions, the cold DSW can be used to manipulate the temperature of seawater to extend the range of temperate high-value seaweeds into the tropics. Malaysia has been identified as suitable for OTEC development, especially in Sabah. An ongoing OTEC research project between Malaysia and Japan includes research on value creation from the OTEC DSW through the cultivation of abalone and seaweeds. It is timely for a comprehensive review of the advantages of using DSW for seaweed farming and how the integration of this innovative technology with the OTEC system can provide value-added products and revenue to both industries, which are important components of the emerging blue economy.
期刊介绍:
Aquaculture International is an international journal publishing original research papers, short communications, technical notes and review papers on all aspects of aquaculture.
The Journal covers topics such as the biology, physiology, pathology and genetics of cultured fish, crustaceans, molluscs and plants, especially new species; water quality of supply systems, fluctuations in water quality within farms and the environmental impacts of aquacultural operations; nutrition, feeding and stocking practices, especially as they affect the health and growth rates of cultured species; sustainable production techniques; bioengineering studies on the design and management of offshore and land-based systems; the improvement of quality and marketing of farmed products; sociological and societal impacts of aquaculture, and more.
This is the official Journal of the European Aquaculture Society.
