Résumé: The researchers will work with other scientists to examine the broad whitefish of the Mackenzie River and associated tributaries of the Arctic Red and Peel Rivers. Features such as population size, migration, growth, age of sexual maturity and mortality will be examined. A study of the traditional knowledge of broad whitefish and fishing in the Mackenzie River will also be developed. Training i...

Résumé: Three crews of two people each will be stationed at the commercial fishing camps to obtain biological and catch effort data from the fisherman. A supervisor will oversee the project in the field and set some experimental nets in the vicinity of the commercial nets at one of the camps. A minimum of 200 whitefish samples will be obtained from the fishermen's catch....

Résumé: 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....

Résumé: The researchers will conduct a mobile hydroacoustic survey from a 20 ft. boat using a BioSonics dual-beam echo-sounder and recording system. A limited amount of gillnetting will be conducted to provide groundtruthing information for the acoustic data. Target strength analysis will also be conducted....

Résumé: The researchers will assess the feasibility of tagging large numbers of broad whitefish in the Mackenzie River Delta. Various fishing gear will be tested to evaluate effectiveness for capture and release of fish. The tagging program may be used to train local natives in tagging methods and techniques. Recovery of tagged fish and/or tags will be effected through active recovery from Inuvialuit f...

Résumé: The Fieldwork will involve removing fish from selected pools by a number of methods including electroshocking, seine and angling. They will be anaesthetized, weighed, measured and tagged. The researcher estimates that no more than 5% of the total catch will be dead sampled....

Résumé: Karl Schwalme wants to know how and why the fat content of pike changes during the year. He will collect about 30-50 great northern pike from each lake by using a 2 1/2 inch gill net which will only be set during the day. He will then take the fish back to the Inuvik Research Centre to determine their fat content. Since some of the fats help to prevent heart disease in people, the annual change ...

Année(s) de permis: 1987
Résumé: To continue the ongoing study designed to investigate the postglacial dispersal patterns of freshwater and anadromous fishes by determining genetic relationships between fish populations inhabiting the rivers. Tissue samples will be collected and the genetic variations will be determined through analysis for selected proteins....

chercheur principal:
Année(s) de permis: 1987
Résumé: To conduct preliminary sampling of small lakes in the general area of Inuvik by "test fishing". The information gathered will be used as a basis to initiate a research project on arctic fish ecology....

Année(s) de permis: 1980
Résumé: To document fish use of shalllow side-channel areas or river margins and to estimate the effect of water level changes on fish habitat. Detailed physical data collection (water levels, velocity and sediment samples) will be undertaken, data will also be collected of fish and small invertebrate use of habitat....
