approval of the Nevada Board of Wildlife Commissioners. Any repatriation
action would need to be included as part of an agreed upon cooperative
management planning document, and (2) as part of an approved
Service/Recovery Team strategy inclusive of the lower basin.
Applicable Recovery Goals and Management Strategies:
Recovery Goal (provisional): Establish and maintain one self-
sustaining population while moving towards recovery.
Downlisting Criteria:
1. Two self-sustaining populations (e.g. mainstem and/or
tributaries are maintained over a 5-year period starting with the first
point estimates acceptable to the Service, such that for each
population:
a. the trend in adult (age 7+ ;> 45 cm TL) point estimates
does not decline significantly, and
b. Mean estimated recruitment of age-6 (40-45 cm TL)
naturally produced fish equals or exceeds mean annual
adult mortality8, and
c. Each point estimate exceeds 2,600 adults.
Delisting Criteria:
1. Two self-sustaining populations (e.g. mainstem and/or
tributaries are maintained over a 7-year period beyond downlisting,
starting with the first point estimates acceptable to the Service,
such that for each population:
a. the trend in adult (age 7+,>45 cm TL) point estimates
does not decline significantly, and
b. Mean estimated recruitment of age-6 (40-45 cm TL)
naturally produced fish equals or exceeds mean annual
adult mortality, and each point estimate exceeds 26,000
adults (MVP).
Management Strategies: This Recovery Goal will be met through
the use of Strategy 1: Augmentation.
