The first submersible cage was launched in the Yellow Sea Cold Water Mass (YSCWM) to culture salmonid. Four cruises were conducted to study the impact of aquaculture activities on the surrounding environment. Results indicated that water quality varied among different sampling times, water layers, and sampling stations. In July and August, low water temperature and high dissolved oxygen concentration were found in the bottom water, which provides a suitable habitat for salmonid culture. Significant correlations were observed between δC values in particulate organic matter (POM) and chlorophyll a concentration in June, August, and April. Seasonal and spatial variations of δC, δN, organic carbon (POC), nitrogen (PN), and C/N in POM were found. Increases in δC, POC, PN, decreases in C/N and changes in δN around the cage suggested the influence of aquaculture to the environment. However, these influences largely disappear in December.
首套潜笼在黄海冷水团（YSCWM）中投入使用，用于养殖鲑鳟鱼类。进行了四次巡航，以研究水产养殖活动对周围环境的影响。结果表明，水质在不同的采样时间、水层和采样点之间存在差异。在 7 月和 8 月，底层水中的水温较低，溶解氧浓度较高，为鲑鳟鱼养殖提供了适宜的栖息地。在 6 月、8 月和 4 月，发现颗粒有机物质（POM）中的 δC 值与叶绿素 a 浓度之间存在显著相关性。在 POM 中，δC、δN、有机碳（POC）、氮（PN）和 C/N 表现出季节性和空间变化。在养殖笼周围，δC、POC、PN 的增加，C/N 的减少和 δN 的变化表明了水产养殖对环境的影响。然而，这些影响在 12 月基本消失。
