Environmental Studies of the Aquatic Resources of Spyder Lake.
Principal Investigator: Reed, Shawna
Licenced Year(s): 1994
Summary: The researcher will determine fish presence/absence and/or densities (number of fish per unit stream length) by electrofishing representative habitat (eg. pool, riffle, run) and the setting of baited minnow traps. When these two methods are not practical (eg. depth too great or flow too fast), gillnets and/or beach seines will be used. Fish caught will be identified, measured, weighed, sexed and t...


Habitat Utilization and Fish Community Structure in the Snare River.
Principal Investigator: Reed, Shawna
Licenced Year(s): 1994
Summary: In this study fish presence/absence and/or densities will be obtained by electrofishing representative habitat and the setting of baited minnow traps. When these two methods are not practical gill nets, trap nets, and/or beach seines will be employed. Each fish caught will be identified, measured, sexed and condition will be noted. Ten specimens of each species from each site (up to 10) will be...


Environmental Studies of the Aquatic Resources in the Lac de Gras Area.
Principal Investigator: Pelletier, Clem
Licenced Year(s): 1994
Summary: In project area streams, fish presence/absence and/or densities will be obtained by electrofishing representative habitat. Benthic invertebrates ans periphyton (stream algae) will be sampled at stream sites to determine seasonal changes in composition, distribution and abundance. Lake fisheries population studies will involve fish trapping. Lake limnology, plankton and benthic invertebrates wil...


Environmental Studies of the Aquatic Resources in the Prairie Creek Area.
Principal Investigator: Reed, Shawna
Licenced Year(s): 1994
Summary: In project area creeks & streams, fish presence/absence and/ or densities will be obtained by electrofishing representative habitat & the setting of baited minnow traps. Each fish caught will be identified, measured, weighed & sexed, & condition will be noted. Furthermore, in order to assess background tissue metal levels, ten specimens of each species must be sacrificed in order to obtain the req...


Shallow water benthic fish communities of Resolute Bay
Principal Investigator: Green, John M.
Licenced Year(s): 1993 1990 1988
Summary: As part of a long-term study, I will continue to make underwater observations of the benthic fishes found in the shallow waters of Resolute Bay. Some fish will be collected for further laboratory studies in order to examine their food habits, growth rates and population growth rates. The species Gymnelus viridis will be studied in greater detail....


Trophic Relationships and Energetics of Arctic Cod in High-Arctic Marine Food Chains
Principal Investigator: Hop, Haakon
Licenced Year(s): 1991 1990 1988
Summary: Mr. Hop and his assistants will collect Arctic cod by trawls and trap nets. Samples of these and other fish will be taken back to the University of Alberta for study....
