DRAFT 



'Hatchery conditions may result in predisposing factors that enhance the 

 susceptibility of juvenile hatchery salmonids to stress and subsequently 

 increased rates of infectious diseases " (emphasis added) 



In isolated instances this statement is true, they may , but the statement gives the 

 impression it is standard hatchery practice: this is not true. 



"The ODFW's ability to recommend time, size, and location of hatchery 

 fish releases has been hindered by an inadequate data base and 

 inconsistent results from past studies, attributed to poor experimental 

 design or disease problems. ' 



The Department is presently building a data base that assists in determining the best 

 times and sizes for release. True, disease is a problem in some cases. The major 

 factor contributing to the variability of the data is variation in environmental factors 

 occurring in both fresh water and marine areas over which man has no control. 

 Hatchery factors over which the Department has control contribute to a very small part 

 of the variability in the results from year to year in fish survival.

The word "may" is used four times in this section in quotes and only serves to provide 

 a possibility of some action occurring, but provides little conclusive evidence to the 

 discussion.

This paragraph discusses primarily past practices with little emphasis on the present. 



Page 48, 1.3.5. Outplanting 



"...this practice is extensive and has persisted for decades. " 



This statement may be true for trout stocking programs, but it is certainly not true for 

 most anadromous salmonids. Outplanting has been greatly reduced in recent years 

 except for fish transported to acclimation sites such as coho to net pens in Youngs Bay 

 or steelhead to acclimation sites in N.E. Oregon.
