B. Append biologically sound definitions and practicable assignment 

 criteria for stock categories to all written policies and guidelines on 

 salmon and steelhead hatchery production in the Columbia Basin. 



C. Define other frequently used terms in order to clarify the intent of a 

 particular policy or guideline. 



D. Develop consistent definitions and assignment criteria for agencies 

 whose actions impact the same or genetically interacting stocks. 



Genetic Goals 



A. Initiate all documents addressing hatchery production with a direct 

 commitment to the following genetic conservation goal (Riggs 1990): 

 maintain genetic resources of salmon and steelhead in native, 

 naturalized, and artificially propagated populations with no avoidable 

 and irreversible losses of genetic diversity resulting from management 

 interventions or inactions. 



B. Consistent with this goal, make conservation of existing wild populations 

 a first priority (AUendorf et al., 1990). 



C. For agencies whose actions impact the same or genetically interacting 

 stocks, establish a consistent approach to meeting this genetic 

 conservation goal by adoption of the production framework delineated 

 in Riggs (1990) and clarified in AUendorf et al. (1990). 



Hatchery Broodstock and Rearing Guidelines 



A. Establish written guidelines for maintaining similar genetic resources 

 and life history patterns in hatchery broodstocks and wild or natural 

 stocks with which they may genetically interact. 



B. Establish consistency in guidelines of different agencies managing stocks 

 in the Columbia River Basin. 



C. Provide written direction on donor stock source, adults mated, 

 fertilization protocol, rearing practices, and size of donor stock 

 remaining for natural reproduction: 



1. Donor stock source: 



Hatchery stocks should be founded from carefully chosen donor populations 

 which have genetic resources and life history patterns similar to the wild or 

 natural stocks with which they may genetically interact (AUendorf et al. 1990).
