few days that they would be in the system, particularly since 

 they will also find themselves in the novel environment of the 

 pipe? Further, do we know that fish will (can) eat while moving? 

 Will having major resting stations that also entail feeding 

 perhaps also create a host of other problems for wild fish (e.g., 

 crowding, species interactions, water quality, etc.)? Careful, 

 thorough research may be necessary here. 



5. Is it possible that fish could get overcrowded in the pipe? 

 Crowding for wild fish may concern vision (nearest neighbor 

 concept) at lower densities before water quality becomes a 

 factor, more of a concern to hatchery fish. Will the proposed 

 plumbing and repeated exiting and re-entering the system cause 

 physical damage (descaling, mucus removal) to the fish, 

 particularly if they are crowded? The pipe would be a place 

 where healthy and diseased individuals are in close proximity, as 

 in present collection/transport systems. Is it possible that 

 fish with and without different loads of pathogens may perform 

 differently? Individual BKD infection level may be important. 

 This will require study. Will the presence of one species of 

 fish adversely affect other species at times when they are 

 sympatric in the pipe? This will also require study. 



6. What are the proposed features of the down-river exit sites? 

 At what depth will they be located, will they be in mid channel 

 and in or out of flow, etc.,? How many exit sites are
