     Fish-sci list members:

     We are attempting to study the effects of various chemicals on
     bluegill survival to approximately 20 days post hatch.  However, we
     are experiencing near 100% mortality (in controls) at about 11 days
     after hatch (25C).  Mortality seems to be due to lack of swim bladder
     inflation and switch from endogenous to exogenous nutrition (we are
     feeding marine rotifers).  We have tried and are continuing to try
     various things to improve the situation but so far, no luck.  Do any
     of you have procedures that might get us at least 50% control
     survival?  Any suggestions/insight would be greatly appreciated.

     Thank you in advance.
