synergies of fluid-induced stresses and AT or of biocide and AT 

 would be most apparent at sublethal temperatures near the lethal 

 limit for the species. Therefore, striped bass flow experiments were 

 run at ambient temperature and at 8.3°C AT, and carp received 

 16.6°C AT. In the biocide experiments, bass were exposed at 

 ambient temperature and at 8.3°C AT. Carp were run at ambient 

 temperature and at 11.1°C AT. Chlorine (as total residual chlorine) 

 was measured by a Wallace and Tiernan amperometric titrator. Free 

 available chlorine was the most prevalent species. 



RESULTS 



Temperature Experiments 



At 24 hr after exposure to short-term thermal stress, striped bass 

 larvae showed a mortality pattern that depended on exposure regime 

 and on the magnitude of thermal stress [Fig. 3(a)]. Larvae exposed 

 to turbulent flow in the collection net (simulator-run and flow- 

 control groups) had similar mortalities, which were higher than those 

 exposed to static-run thermal stresses (barrel controls) (P < 0.012). 

 By 48 hr the mean mortality of all static controls had increased from 

 27.8 to 47.9%, and the analysis of variance disclosed no differences 

 among exposure regimes (P < 0.33).
