Potential Use of Environmental DNA to Monitor Brook Trout Population Dynamics, Washington Creek, Ontario

The project objectives include testing and application of a non-invasive environmental DNA (eDNA) methodology to determine presence/absence of brook trout fish species in the Grand River sub-watershed. In addition, brook trout population abundance and biomass estimates based on eDNA signal intensity are compared to the relative estimates of abundance/biomass obtained from traditional surveying methods (e.g., electrofishing). This data set is collected for the Pillar 3 project titled Next Generation Solutions to Ensure Healthy Water Resources for Future Generations, under the Global Water Futures Program funded by Canada First Research Excellence Fund.

本项目目标包括测试并应用非侵入式环境DNA（eDNA）方法，以检测格兰德河子流域内溪红点鲑（brook trout）物种的存在与否。此外，本研究将基于eDNA信号强度估算的溪红点鲑种群丰度与生物量，与传统调查方法（如电捕鱼法）得到的丰度/生物量相对估算值进行对比。本数据集为隶属于由加拿大首席研究卓越基金资助的全球水未来计划的第三支柱项目"保障子孙后代健康水资源的下一代解决方案"所采集。
