A novel fish estuary-association scoring (FEAS) system that numerically expresses the relative position or level of estuarine-association for each species has been developed. A dataset numerically describing the degree or level of estuarine-association for some 6,000 fish species has been established based on an extensive review of the scientific literature on coastal and freshwater fishes. The FEAS reflects both globally recognized fish estuary-association functional guilds as well as the continuum of fish estuarine use and dependence. The application of FEAS to numerically analyse and functionally compare estuarine fish communities using a range of statistical and analytical methods is demonstrated by examples from a variety of studies around the world; its use as a potential environmental monitoring and assessment tool is also presented.

鱼类河口协会的全球评估：评估与河口相关的鱼类功能协会的数值方法

已经开发了一种新的鱼类河口关联评分 (FEAS) 系统，该系统用数字表示每个物种的河口关联的相对位置或水平。基于对沿海和淡水鱼类科学文献的广泛审查，已经建立了一个数据集，以数字方式描述了大约 6,000 种鱼类的河口关联程度或水平。FEAS 反映了全球公认的鱼类河口协会功能协会以及鱼类河口使用和依赖的连续性。世界各地各种研究的例子证明了 FEAS 在数值分析和功能上比较河口鱼类群落使用一系列统计和分析方法的应用；还介绍了它作为潜在环境监测和评估工具的用途。
