Keith Parker is the AISES 2023 Technical Excellence awardee. He is a senior fisheries biologist for his Yurok Tribe, working at the intersection of Western and Indigenous science. Parker is a frequent speaker on the impact of climate change and drought on salmon populations, and witnessed the largest adult fish kill in U.S. history (68,000 adult Chinook salmon) on the Klamath River in 2002. The kill was due to unjust water flow management relative to multiple river dams; and today the Yurok Tribe is preparing for the nation’s largest-ever dam removal project, which will reopen 400 miles of Klamath fish habitat. In childhood, Parker watched his grandfather protest federal bans on tribal fishing rights; and ironically, he is responsible now for co-stewarding the Klamath River’s 44 miles through the Yurok reservation. He also has family in Karuk, Hupa and Tolowa communities. A participant in AISES’ Lighting the Pathway Indigenous research career program, Parker’s own research has combined thousands of generations of scientific tribal observation with cutting-edge genetic sequencing. In 2018, he discovered two new subspecies, or ecotypes, of Pacific lamprey (a jawless fish that resembles an eel)—one that matures in the river and one that matures in the ocean. Lamprey has great cultural and historical value to Pacific Northwest tribes.
