Objectif(s): To collect samples of sexually mature adult pike; to determine the polyunsaturated fatty acid content of these fish; to compare the results with those from pike collected in central Alberta; to determine the types of seasonal changes in fatty acid composition in relation to hormones, temperature, and diet

Description du projet: 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 has nutritional impacts.
