Habitat Preferences of Slimy Sculpin and Rainbow Trout in Grout Brook, New York, 2016

In association with a project to estimate stream habitat use by two fish species; habitat parameters where slimy sculpin and rainbow trout were captured were recorded. Habitat use was observed using a backpack electrofisher in order to determine where fish were residing. Total stream habitat was calculated using equally spaced transects with observational recording of stream water depth, stream velocity, vegetative cover, and stream bed substrate composition. Comparisons of habitat use between the two species were analyzed using several statistical programs to infer competition or segregation.

本数据集关联一项旨在评估两种鱼类对溪流生境利用情况的研究项目。研究记录了捕获黏糊杜父鱼（slimy sculpin）与虹鳟（rainbow trout）时对应的生境参数。为明确鱼类的栖息位置，研究采用背负式电渔法开展生境利用观测。通过布设等距样带并观测记录溪流水深、流速、植被覆盖度以及河床底质组成，计算得到总溪流生境范围。采用多款统计软件对两种鱼类的生境利用情况开展对比分析，以推断二者的种间竞争或生境分化关系。
