supplementation processes correctly and effectively. The 

 entire Snake River ecosystem must be safeguarded against 

 ecological disruption and overload resulting from poor use 

 of the hatcheries. 



A principal product of this coordinated approach to 

 improved chinook production must be a set of standards and 

 guidelines. Some areas and their stocks should not receive 

 hatchery intervention. Natural processes should restore 

 stock strengths as adults return in increasing numbers (due 

 to improvements made at other stages in the life cycle — as is 

 presently the case for the Middle Fork of the Salmon River). 

 Stocks in other areas may need hatchery fish 

 supplementation, but with carefully planned safeguards that 

 take into full account the risks and problems of that kind of 

 intervention. Carefully planned, monitored, and evaluated 

 experimental approaches will be needed in selected areas to 

 improve the Region's abihty to use these artificial
