Bottlenecks to Survival is part of the PSF
Marine Science Program
This interactive dashboard was developed by the Bottlenecks to Marine Survival Project in partnership with the Snuneymuxw First Nation to provide a centralized platform for assessing preliminary results from the Bottlenecks Project. It presents data on PIT-tag deployments across multiple life stages—hatchery, river, estuary, and microtroll—during the first year of life for Summer and Fall-run Nanaimo River Chinook. Detections of PIT-tagged fish are at the mainstem array located under the Cedar Highway Bridge, at tidewater in the Nanaimo River.
Users can explore the dashboard’s interactive features to dynamically filter and analyze the data. Selecting a specific Chinook stock (Fall vs. Summer) from the dropdown menu or clicking on variables within the pie charts will update figures in real time, allowing for detailed comparisons across tagging stages, return years, and genetic classifications.
