| Abstract | Thirty-day old fathead minnows were raised to maturity and spawning in a laboratory flow-through system using softened water at various pH and Al levels. Successful spawnings were reduced by more than 85% at pH 6.0, 5.5-25 microg/L Al+3, and 5.5, and absent in all pH 5.2 treatments. Hatching success, larval survival, swim bladder development and yolk absorption were reduced or abnormal when spawning did occur at lower pHs. |
