Seine Collection Data Along the Michigan Shoreline of the St. Clair-Detroit River System

These data contain counts of fish species collected with a 1.83 m x 9.14 m bag seine constructed of 1.6 mm Delta nylon mesh. When permitted, five consecutive 15.25 m hauls were made parallel to the shoreline. Sites with smaller shorelines were sampled to the greatest extent possible and distance recorded. The seine was pulled in the upstream direction to allow the net to stay open during sampling. Following each haul, fish were sorted by species and counted. Macrophyte community characteristics (percent cover and species) were assessed by visually approximating the proportion of sites occupied by each species. A rake was used to collect vegetation for lab verification of species identification. Other habitat features including shoreline vegetation types, water temperature and bottom substrate types were also recorded.

本数据集收录了采用规格为1.83米×9.14米、网目尺寸1.6毫米的Delta牌尼龙网布制作的袋形曳网（bag seine）采集得到的鱼类物种计数数据。在获得许可的前提下，沿海岸线平行开展连续5次、单次长度15.25米的拖程采样；对于岸线较短的采样点，则尽可能增加采样次数并记录采样距离。拖网沿上游方向拖拽，以确保采样过程中网具始终保持张开状态。每次拖程采样完成后，按鱼类物种进行分拣并逐一计数。大型水生植物群落特征（盖度百分比与物种组成）通过目视估算各物种所占采样点比例的方式进行评估；同时使用耙具采集植被样本，用于实验室物种鉴定的验证。其余生境特征，包括岸线植被类型、水温及底质类型，亦同步记录在册。
