great as or greater than mortality caused by plant passage. Since the 

 questions of collection mortality, mechanical damage, and thermal 

 shock have yet to be resolved, further simulator tests will certainly 

 yield valuable results for detailed analysis. 



Collection mortality in the simulator system is of great signifi- 

 cance. Future testing will be conducted, not only with standard 

 collection devices but also with the newly developed LMS larval table 

 (McGroddy and Wyman, 1977). 



Several controversies presently reign with regard to power-plant 

 operation in biologicsilly active areas. Views on the resolution of 

 these controversies differ widely and tend to be supported with great 

 tenacity and emotion, despite an overall paucity of relevant data. At 

 least some of these factors, e.g., fluid-induced stress and various 

 physical— chemical synergies, lend themselves to analysis with the 

 simulator and other devices like it.
