End Date: Apr 30, 2012

Objective:
Rainbow trout have been evaluated and bred for two generations at the National Center for Cool and Cold Water Aquaculture for increased survival following experimental challenge with the causative agent of bacterial cold water disease (BCWD), Flavobacterium psychrophilum. The objective of this research is to determine whether laboratory-based evaluation translates to superior performance under natural challenge conditions. This project will evaluate select-line fish performance at two Utah Division of Wildlife Resources facilities.

Approach:
Approximately 70,000 eyed eggs from the ARS-Fp-R (resistant) line will be generated at the NCCCWA and transferred to two Utah Division of Wildlife Resources facilities. Eggs will be hatched and fish will be reared under standard production conditions that typically result in BCWD outbreak. This field-trial will evaluate three parameters: 1) production and shipping of eggs; 2) obtain baseline/comparative production and health condition profile data from ARS-Fp-R line fish; and 3) investigate the incidence and severity of BCWD infection.
