Objectif(s): To collect benthic macroinvertebrates in 70 lakes in the Yamba River basin.
Description du projet: This licence has been issued for the scientific research application No. 5647. The main objective of this research project is to further inform the story of how cumulative effects impact lake systems in the Yamba River basin. The research team intends to accomplish this by collecting benthic macroinvertebrates in 70 lakes in the Yamba River basin to compliment water quality data that were collected in 2020-2023. Benthic macroinvertebrates will be collected using 5 x 1 minute kick sweeps on the shores of each lake on sand/pebble/cobble shores. Samples will be collected using a triangle frame, 400 micron net. Samples will be stored in 500 mL plastic jars in 70% isopropynol. Water samples will be collected and physical measurements of the water will be taken (temperature, pH, dissolved oxygen, specific conductivity and turbidity) Benthic macroinvertebrates will be analyzed using Environment and Climate Change Canada’s Canadian Aquatic Biomonitoring Network (CABIN) laboratory methods: processing, taxonomy, and quality control of benthic macroinvertebrate samples. On June 6, 2023, the research team in NWT CIMP will discuss this project with its Steering Committee. The discussion will take place over video conference, with visual PowerPoint slides showing the proposed project plans. Discussions will address the rationale for adding an additional component to the initial pilot project that looked at the cumulative impacts of natural and human made disturbances on water quality. During the monitoring program, the research team will have regular (every 6 months) discussions and updates with the stakeholders to discuss project progress, preliminary findings and any questions or concerns. The fieldwork for this study will be conducted from July 28, 2023 to August 08, 2023.
