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
Analysis of DFO's own data by the SFU researchers and researchers from other institutions reveals that the annual number of streams the DFO monitored has steadily decreased to its lowest level ever. This, despite a key commitment of Canada’s Wild Salmon Policy to assess the health of salmon populations, and to increase the abundance of those populations deemed at risk.
One of the five key recommendations in the article calls for increased federal funding to ensure that salmon are adequately monitored, which equates to <1% of the $1.4 billion in additional funding recently allocated to DFO’s Pacific Region over the next 5 years.
Visits to spawning streams provide vital information on trends over time, and biological status required to guide fisheries and conservation. Without such information, fisheries may continue to catch diminished populations without the necessary warning bells being sounded.
“Our knowledge of salmon populations in B.C. is eroding rapidly,” says Price. “Without increased support for annual spawning surveys, the rich legacy of population data available for B.C.’s coast is at serious risk of becoming irrelevant for future assessments of management and conservation status.”
Indeed, “you can't manage salmon populations if you don't know how they're
• Annual counts of spawning streams have declined by 70
• Today, the status of 50
• The Fraser River sockeye commercial fishery closed in July due to lower than expected returns;
• Low returns of Skeena River sockeye in 2017 prompted commercial, recreational, and food-fishery closures for First Nation communities along the river;
• Diminished salmon returns negatively impact the B.C. salmon fishing industry
(commercial and recreational), which annually contributes $500 million and ~4,000
