Estuarine dependency by certain fish species has been clearly demonstrated in a number of studies, but the term has also been used for those species and guilds that are not dependent on estuaries. The origins and development of the term are explored, and definitions for four types of estuarine fish association are provided which may be helpful in facilitating classification and comparisons between fish taxa using estuarine systems in different parts of the world. In addition, a diagrammatic representation of more recent estuary-associated guild categories is presented to provide context and clarity on the estuarine dependency issue, and the fact that a continuum in terms of dependency is perhaps most appropriate for describing fish species relationships with estuaries. ETHICAL STATEMENT: This brief communication is a philosophical discussion and did not involve the capture, use or care of any living or dead fish. Therefore, no permit or animal ethics clearance was required to undertake the literature review.
某些鱼类对河口的依赖在许多研究中已经得到了明确的证明，但该术语也被用于那些对河口不依赖的鱼类物种和类群。本文探讨了该术语的起源和发展，并提供了四种类型的河口鱼类组合的定义，这可能有助于促进对来自世界不同地区的河口系统中的鱼类分类和比较。此外，还提出了一个更近期的与河口相关的 guild 类别的图表表示，以提供关于河口依赖问题的背景和清晰度，以及在描述鱼类与河口的关系方面，依赖的连续性可能是最恰当的。
