About Ben Kennedy

Ben serves as the primary lead for field activities coordinated by Abernathy FTC. His primary responsibilities are associated with a large-scale multidisciplinary project examining the natural reproductive success and demographic effects of hatchery-origin steelhead in a lower Columbia River estuary. His duties include coordinating field activities such as electrofishing, sample collection and PIT tagging. Additionally, he performs statistical analyses of data related to growth, mitigation, behavior, life history, survival and abundance.

Assessing superimposition of listed tule fall Chinook salmon redds using aerial and ground surveys on the White Salmon River, Washington

Upriver bright (URB) fall Chinook salmon reared and released from the Little White Salmon and Willard National Fish Hatcheries are known to stray into the White Salmon River. Interactions between hatchery-origin URB strays and ESA-listed tule fall Chinook salmon are believed to lead to a loss in...

Assessing superimposition of listed tule fall Chinook salmon redds using aerial and ground surveys on the White Salmon River, WA

Hatchery upriver bright (URB) fall Chinook salmon are straying into the White Salmon River (Figure 1). ESA-listed tule fall Chinook population in the White Salmon River spawns earlier (Sept – Oct) than URBs (late Oct – Nov). Tule redds at risk to superimposition which may displace eggs and...
