New Salmon Escapement Database System (NuSEDS)

NuSEDS is the Pacific Region’s centralized Oracle database that holds adult salmon escapement data. About 10,000 salmon spawning sites in DFO Pacific Region have been observed 0 to 10 times per year for 6 species for nearly 100 years (poorly before 1948). Data is aggregated within year; the raw data is largely on paper.
