Abstract
Effects of total residual chlorine (TRC), change in temperature (.DELTA.T) and exposure time were established for eggs and prolarvae of striped bass, M. saxatilis, under test conditions designed to simulate entrainment by power plants. Prolarvae were more sensitive than eggs under the same test conditions. In contrast to the predominant effect of TRC and exposure time on eggs, TRC, .DELTA.T and exposure time were all important in causing mortality of prolarvae. [A predictive mortality model was discussed.] In an evaluation of the potential effects of chlorinated power plant cooling waters to striped bass ichthyoplankton, a systematic study must be made of the interactions of TRC, .DELTA.T and exposure time.
