The kinds (taxa) and abundance of all invertebrate species were determined from replicate samples. In conjunction with this task, the food of mountain whitefish and northern pike were determined for this same reach. The stomach contents were weighed, and each food item was identified and measured. The data presented in this report will provide key information for modelling the fate of pulp mill contaminants and determining levels of contaminants in mountain whitefish and pike."--Study perspective. |
