Fall Chinook

Do fall Chinook salmon traveling through a 40' or a 250' Whooshh fish transport system incur additional physiological stress compared to the trap and haul transport or control net transport fish?

the conclusion

No. There was no significant difference in elevated immune response levels among the study groups measured 2-3 days post-transport. Additionally, there was no indication of a difference in female cortisol levels, as an indicator of stress, attributable to the Whooshh Fish Transport System experience.
