Résumé: 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...

Année(s) de permis: 1988
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 ...
