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 the study are to document traditional ecological knowledge of Rat River char. Specifically, the researcher will be asking questions about: catch of char; biology of char (e.g., spawning, migration); fishing practices; fishing at the Rat River fish hole; observations on the land related to char; changes in the environment related to char; char predators - concerns and observations...

Summary: This is a continuing project to survey fish populations of lakes and rivers. In the past population studies have been conducted in the Fish and Raddi lakes, the Sachs River and the Benard River. This year Middle and Kuptan lakes will be surveyed and if there is time Capron and Swan lakes may also be surveyed. The project will also continue studies on genetic and morphological variation in Arcti...

Summary: Fish (most likely Arctic charr) will be obtained either by purchase or by individual collection to analyze for chlorinated organic industrial compounds, pesticides and mercury. Few of these contaminants were ever used in the Arctic. They have been shown to travel to the Arctic through the atmosphere and accumulate in lake sediments and in fish tissues. An attempt will be made to relate the level o...

Summary: The researchers are interested in understanding how prolonged cold conditions and reduced food availability in winter affect char. Sea-run char must increase their fat levels so that they have enough energy stored for overwintering and reproduction. Research activities will also include collecting fish and invertebrate specimens to make comparisons about cold tolerance and diet of these specimen...

Licensed Year(s): 1993
Summary: This project was initiated following the concern voiced by the six ISR communities about the presence and levels of contaminants in the major country food sources. Samples of body tissues will be taken from charr, whitefish, seals and belugas in order to assess for heavy metal, organochlorine and PCB contaminants. These samples will be taken while other field research is being conducted by Fishe...

Summary: Anadromous arctic charr, currently viewed of as the eastern form, are known to spawn and overwinter in the DeSalis River system. Residents of Sachs Harbour have expressed an interest in harvesting arctic charr from this system for consumption and commercial purposes. Two resident monitors will sample the subsistence catch of this stock in order to estimate stock size and age. Whole fish will be ...

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...

Summary: HTC members have counted, measured and sampled all fish that were caught in the domestic fishery located at the mouth of the Hornaday River for the past several years. This season represents the fourth year of the monitoring program. HTC members will collect information on arctic charr that are caught by the fishery....

Summary: In 1992, most charr fishing by Aklavik residents took place at Shingle Point and the town site in Aklavik (similar to fishing during the 1987-1991 closure). In this first year of the monitoring program, information will be collected on the total number of charr caught, harvest locations and characteristics of tagged fish....
