Project: An Evaluation of Immune Responses to Whirling Disease among Trout above and below a Potential Point Source of Myxobolus cerebralis Infectivity in the Colorado River

Primary Investigator: R. Barry Nehring
Project Summary: This ongoing experiment is comparing the immune responses of brown and rainbow trout fry, and comparing mortality rates at varying locations from the "hot spot" -Windy Gap Reservoir on the Colorado River. To date, the youngest wild rainbows exposed directly below the dam were found more likely to die than those exposed directly upstream or downstream. Average mortality: (a) above reservoir-56%, (b) spilling basin-69%, (c) bypass outlet channel-77%, (d) 26 km downstream-37% The pattern was not duplicated with the other three treatments which included brown trout, and two groups of larger and older rainbow trout.
