Summary:
This study aims to use genetic markers and otolith microchemistry to determine if differences exist between putative Arctic cisco spawning aggregations in tributaries of the Mackenzie River (Peel and Arctic Red rivers); and, if differences do exist, to use this information to identify population-of-origin for fish caught in the Colville River subsistence fishery.
During the summer or fall (1 Au...

Summary:
Currently, little information exists on the fisheries resources of the Arctic Red River. Baseline information on fisheries resources is required to make sound management decisions. This information (e.g., biological characteristics of fish: length, weight, age at maturity, migration patterns, date of spawning; presence/absence of species) is collected through long-term studies, traditional knowled...

Summary:
This study involves the determination of the population structure of fish in the Mackenzie River. Specific objectives include the delineation of stocks of three fish species: loche (Lota lota), crookedback (Coregonus clupeaformis) and coney (Stenodus leucicthys), and the identification of downstream fisheries as mixed-stock or single-stock fisheries. A population genetics approach will be employed...

2004 Summary:
Consistent with the DFO authorization, the major objectives of the study are to provide annual documentation of shoal habitat use by Lake Trout in the vicinity of the mine site, and to ground truth hydroacoustic equipment.
Study locations for 2005 are as per 2004. Hydroacoustic surveys are to be conducted during the early morning or evening hours. The survey is conducted at the same time each...

2004 Summary:
The objective of this research is to study what lake trout, whitefish and pike eat and their movements in a small northern Shield lake (Chitty Lake).
Transportation of personnel and equipment into and out of Chitty Lake will be by single engine float plane (Air Tindi). During this study, the researchers will use standardized gill nets, a backpack electroshocker, a seine net, VEMCO acoustic tra...

Summary:
The objective of this study is to establish a baseline collection of tissue and fin samples from broad whitefish that will eventually be used for phylogeographic analysis and the classification of their genetic population structure.
Local Gwich’in and Inuvialuit fishermen will be asked, on a volunteer-only basis, to collect fins or tissue samples from broad whitefish caught during the subsisten...

Summary:
The objective of the fish-out is to provide scientifically defensible data to: (1) quantify fish production, fish habitat and productivity of the intermediate trophic levels (primary and secondary producers); (2) establish linkages between fish habitat and fish productivity in Sable and Two-Rock Lakes; (3) establish a reference database through which comparisons among lakes can be conducted; and (...

19961990 Summary:
The objectives of the research are 1) to collect remains of Silurian and Devonian fishes, and 2) to collect remains of Silurian trilobites. Activities are limited to travel, residence at camp locations and collection of fossils. Helicopters will be used to access camp sites. We plan to land at Avalanche Lake on July 15, spending 6 days collecting fossils at Avalanche Lake, followed by one day of t...

Summary:
Vegetation communities along the pipeline route and over other parts of the Project area would be provisionally mapped from aerial photographs. A field survey would be undertaken with an emphasis on identifying rare plants. The study area is in the Caribou Hills IBP site 4-9, which was in part proposed because of its rare flora. July is an optimum time for a single survey. Also transect sampling ...

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...
