physiological processes of fish, this variable will have to be 

 considered. 



2. Is it good or bad for the fish to be in a pipe that allows 

 the penetration of light as proposed? It is know that fish use 

 vision to hold their position in streams, will the fish fight the 

 current in the pipe? Alternatively, perhaps being in a dark pipe 

 for extended periods of time is stressful. This may have to be 

 researched. If it is healthier for fish to have some light, how 

 will the pipe be kept clean from algae etc. that will prevent 

 light penetration? 



3 . We know that within a species of salmonid that there can be 

 different juvenile migration patterns. Do we know that it is 

 good for all types of migrants to be delivered rapidly below 

 Bonneville or do some migrants need significant time to develop 

 into "good smolts" en route? Will fish, even true smolts, 

 exiting the system bellow Bonneville have the capacity or 

 motivation to migrate further without a recovery period, and if 

 they do, will they be able to adjust to the salinities that they 

 would shortly encounter? Evaluations on migratory behavior, 

 swimming ability, and seawater adaptability are needed. 



4. Some forms of outmigrants apparently need to feed during 

 their migration. It is proposed that food can be added at 

 pumping sites. What kind of food (e.g. artificial) would be 

 added and do we know that wild smolts will accept it within the
