Includes bibliographical references (page 6). "...This project report describes results of a follow-up investigation to an earlier Northern River Basins Study project (NRBS Report # 22). Fish, water and biofilm obtained from other NRBS collections were the source of material used for analysis. Carbon and sulphur results from this project have extended our understanding of the feeding and movement offish in the middle and lower Athabasca River, and the upper and lower Peace River. As well, the nitrogen analyses has assisted in the definition of the food chain relationship of various aquatic biota"--Study perspective. Issued also in print format.
