南极“粮仓”！我国磷虾研究促进产业升级

Core Viewpoint - The research on Antarctic krill is driving industry upgrades in China, highlighting its potential as a valuable biological resource and a source of high-quality protein for human consumption [1][3]. Group 1: Importance of Antarctic Krill - Antarctic krill is one of the largest single-species biological resources on Earth, often referred to as the "granary" of the Southern Ocean [1]. - Krill serves as a crucial food source for various marine species, including fish, penguins, seals, whales, and seabirds, supporting a complete marine food web [3]. - The nutritional value of krill, rich in protein, unsaturated fatty acids, and astaxanthin, surpasses that of beef and shrimp, making it a promising source of high-quality protein for humans [3]. Group 2: Research and Development Initiatives - China has rapidly advanced its research on krill by utilizing polar research vessels like "Snow Dragon" and "Snow Dragon 2," establishing a polar biological gene bank and a national polar science data center [3][5]. - Since 2018, the Amundsen Sea has been a focal area for China's Antarctic research, with ongoing comprehensive investigations into the marine ecological environment [3]. - The development of an onboard intelligent guidance system allows for real-time monitoring of krill powder's nutritional components, enhancing research capabilities [5]. Group 3: Industry Upgrades and Sustainable Practices - The krill processing industry in China is evolving from traditional products like dried krill and krill powder to advanced products such as high-phospholipid krill oil and bioactive peptides [5]. - Research is being conducted to analyze krill distribution patterns, feeding habits, and food chain relationships to promote sustainable utilization of marine resources and environmental protection [6]. - As a member of the Convention on the Conservation of Antarctic Marine Living Resources, China is actively contributing research data and scientific solutions to enhance understanding of climate change impacts on polar ecosystems [6].
