Summary: This licence has been issued for the scientific research application No. 5657. The main objective of this research is to collect eDNA samples to determine the essential habitat requirements of Dolly Varden and to maintain the temperature monitoring network in Fish Creek. For eDNA collection, two litres of water will be collected in the stream and a portable pump will be used to filter the wat...

Summary: This licence has been issued for the scientific research application No.5467. Objectives: To improve sustainability of Dolly Varden fisheries from the perspective of the Gwich’in and Inuvialuit communities that rely on them. Within that, specific Project Objectives include: 1) Document Indigenous Knowledge of population trends, environmental change, and cumulative impacts for Dolly Varden an...

Summary: The first phase of this field program was implemented in 2018, where approximately twenty loggers were deployed and retrieved. A minimum sample size of seventy is required to build a robust stream temperature model. The research team propose to deploy July 14-15 and retrieve August 29-30 the remaining temperature loggers (n = 50) across the Fish Creek watershed. This data will be used to develop a...

Summary: The research teram seek to build on the 2014 & 2015 success in monitoring habitats and using electrofishing to assess juvenile Dolly Varden occupancy. Specific objectives include: 1) continue implementing a community-based monitoring program to monitor essential habitats; 2) further delineate the spatial distribution of juvenile char in the Fish Creek watershed; and, 3) finalize the occupancy mode...

Summary: The objectives of this research project are: 1) to re-assess the anadromous component of the known Vittrekwa River Dolly Varden char population; 2) to investigate & assess other potential suitable Dolly Varden habitat; and 3) to confirm the presence of Dolly Varden char in the Stony Creek watershed. For the Vittrekwa River the research team plans to construct a fixed weir which will trap se...

Summary: The objectives of this research are to: 1) Describe communication and knowledge sharing linkages among the network of local, regional, and government organizations involved in Dolly Varden char subsistence fisheries management processes. 2) Analyze the role of bridging organizations (Fisheries Joint Management Committee and Gwich’in Renewable Resource Board) in the fisheries co-management proces...

Summary: The northern subspecies of Dolly Varden char is represented by only five populations in Canada. Of these populations, the Vittrekwa River Dolly Varden has been least studied. In the late 1990s, the presence of this fish was confirmed by the Gwich’in Renewable Resource Board and the Department of Fisheries and Oceans. Data collected through studies conducted by these organizations showed that at le...

Summary: Dolly varden charr that use the Babbage, Firth, Big Fish and Rat Rivers spend the summer months in the estuary off of the Yukon North Slope. It is not yet known to what extent charr from each of these rivers mix while they are together during the summer. The researchers will be at King Point during the course of other duties and will catch and radio tag ten charr in order to monitor the fish's m...

Licensed Year(s): 1992
Summary: A deflection board weir was used to assess the size of the upstream run of dolly varden charr at Big Fish River in 1991. Results suggested that migrant non-spawners may have been deterred by the weir. Consequently, the 1992 attempt to estimate run size used tagging methods at the Cache Creek site. The fish tagged at Cache Creek will be captured at the Fish Hole in the fall in order to produce a...
