No mortalities or other adverse effects were noted in control or test tanks throughout the study period. The results indicate that the LC50 of L-744,341 to Rainbow Trout is greater than the solubility of L-744,341 in water, achieved under test conditions. The No Observed Effect Concentration (NOEC) is concluded to be equal to this concentration.
