About Justin Baker
Justin is the Hatchery Evaluation Team representative for the Little White Salmon and Willard NFHs upriver bright fall Chinook Salmon programs. He supports monitoring and assessment of hatchery production and performance, as well as evaluating potential impacts of hatchery-origin strays on ESA listed populations in the White Salmon River. Justin also conducts annual monitoring of juvenile outmigration timing and survival of hatchery releases through the Columbia River system for four hatcheries within the Columbia River Gorge NFH Complex.
Program: Hatchery Assessment
Current Projects:
• Monitoring survival of out-migrating juvenile Chinook salmon releases from Carson, Little White Salmon, Warm Springs and Willard NFHs
• Analyzing PIT tag and adult return data from alternative juvenile release strategies implemented at Willard NFH starting in 2018 to provide recommendations to hatchery managers for future releases
• Monitoring movements and straying of returning adult upriver bright fall Chinook salmon from the Little White Salmon River using submersible PIT detection antennas
• Collaborating with biologists at Abernathy Fish Technology Center and WDFW on genetic study of fall Chinook Salmon carcasses from the White Salmon River to monitor hybridization between hatchery-origin URB fall Chinook Salmon and ESA-listed tule fall Chinook Salmon
• Evaluating the impacts of redd superimposition by hatchery-origin URB fall Chinook Salmon on the spawning success of listed tule fall Chinook Salmon in the White Salmon River
• Supporting hatchery staff at Warm Springs, Spring Creek, Carson, and Little White Salmon NFHs with spawning activities and biosampling
Background: Before coming to work at the CRFWCO in 2021 Justin spent seven years as a fish biologist with an environmental consulting firm in Saint Louis, Missouri. Justin went to the College of Wooster in Ohio, home to the Fighting Scots. He went on to study the genetics of darters including those isolated in Ozark refugia and received graduate degrees in Biology from Saint Louis University. While completing his PhD degree he worked for three years at The Ohio State University Museum of Biodiversity conducting fish surveys throughout Ohio and cataloging fish for the museum collection. As an environmental consultant in Saint Louis Justin worked on multiple projects including evaluating negative impacts at power facilities from entrainment of fish eggs and larvae including those of pallid sturgeon.
At CRFWCO since: 2021
