Scientific Significance Statement

Aquaculture is a global industry that enriches the surrounding aquatic environment in nutrients, namely carbon, nitrogen, and phosphorus. Because these inputs are spatially and temporally defined, cage culture farms act as perturbation experiments for understanding the ecological impacts of nutrient enrichment on aquatic ecosystems. Individual farms form an existing, though underutilized, global network of experiments with established continuous monitoring of ecosystem impact metrics. This network covers both freshwater and marine environments and spans numerable environmental gradients. We propose that this global coverage provides an opportunity to better understand heterogenous aquatic ecosystem response to nutrient enrichment in the context of other current global changes. With increased data sharing efforts and interdisciplinary collaboration, this existing global network of perturbation experiments provides an opportunity to expand fundamental understanding of diverse ecosystem response to nutrient enrichment.

水产养殖业作为全球扰动实验网络

科学意义声明

水产养殖是一个全球性产业，可以丰富周围水生环境的营养物质，即碳、氮和磷。由于这些输入是在空间和时间上定义的，网箱养殖场可以作为扰动实验来了解营养物富集对水生生态系统的生态影响。各个农场形成了一个现有的、尽管未得到充分利用的全球实验网络，并建立了对生态系统影响指标的持续监测。该网络覆盖淡水和海洋环境，并跨越无数的环境梯度。我们认为，这种全球覆盖范围为更好地了解当前其他全球变化背景下异质水生生态系统对养分富集的反应提供了机会。随着数据共享工作和跨学科合作的增加，现有的全球扰动实验网络提供了一个机会来扩展对不同生态系统对养分富集的响应的基本了解。
