Salish Sea Ecosystem Conference
Between 1987 and 2000, nesting populations of Pelagic Cormorant (Phalacrocorax pelagicus; PECO) and Double-crested Cormorant (P. auritus; DCCO) declined in the Strait of Georgia, BC. This northern section of the Salish Sea is a rapidly urbanizing area, and piscivorous birds are important indicators of ecosystem health. To update population status, we conducted a complete survey of 35 PECO and 23 DCCO colonies in July 2014 and opportunistic surveys of some colonies between 2001 through 2015. The PECO population decreased from ~2100-2400 nests in 1959-1987 to ~1100 nests by about 2000, and then rose slightly …

Salish Sea Ecosystem Conference
The first fish tracking arrays were deployed in the Salish Sea over a decade ago. These arrays have yielded a rich data set which have provided the first direct estimates of early marine-survival and migratory behavior for acoustic-tagged juvenile sockeye, Chinook, Coho and steelhead >130 mm in fork length (FL). In spring of 2015, as part of the Salish Sea Marine Survival Project, the Pacific Salmon Foundation, the Ocean Tracking Network and Kintama Research deployed additional arrays in the Discovery Islands and Johnstone Strait (north of the Strait of Georgia) to provide higher resolution survival data. These new arrays use …
