Multi-decadal bycatch datasets and analyses of headwater stream fishes in the Salmon River, Idaho

Bycatch data are commonly collected during studies of focal species, yet these data are often underutilized in understanding the ecology of these same focal species. A multi-species approach to focal species ecology offers several advantages, including broader scope of detection of habitat and resource changes, indicator species or surrogate species approaches, and documentation of species which may in the future be of conservation or management concern. This archive contains a multi-decadal fish community dataset collected as bycatch data during a focal study of Chinook Salmon (Oncorhynchus tshawytscha) parr in from natal headwater streams in the Salmon River, Idaho, as well as covariate data to explain community structure. The project using these data focuses on identifying lessons from broader community-based approaches to understanding ecological patterns and processes important for Chinook Salmon in their natal habitats. Data are stored in .csv and .rds format, and are fully documented in a companion ReadMe document.副渔获物数据通常在焦点物种研究中被采集，但这类数据在解析同类焦点物种的生态学特性时往往未得到充分利用。针对焦点物种生态学的多物种研究方法具备多重优势，可扩大生境与资源变化的检测范围，支持指示物种或替代物种研究路径，同时可记录未来可能纳入保护或管理范畴的物种。本数据集存档包含一项多年代的鱼类群落数据集，该数据集作为副渔获物数据，采集自爱达荷州鲑鱼河原生源头溪流中针对奇努克鲑（Chinook Salmon，*Oncorhynchus tshawytscha*）稚鱼开展的焦点研究，同时附带用于阐释群落结构的协变量数据。依托本数据集开展的研究项目，旨在总结基于群落的拓展研究方法的经验，以解析奇努克鲑原生栖息地中关键的生态学模式与过程。数据集以.csv和.rds格式存储，并附带完整的配套ReadMe文档予以说明。
