The Department of Fisheries and Oceans Canada (DFO) is not monitoring enough spawning streams to accurately assess the health of Pacific salmon, according to a new study led by Simon Fraser University researchers Michael Price and John Reynolds.The study, published in the Canadian Journal of Fisheries and Aquatic Sciences, reveals that the DFO does not have enough data to determine the status of 50 per cent of all managed salmon populations along B.C.’s north and central coasts.
