Discussion  Monomictic or Dimictic ?  Isothermal conditions at time of survey  Problems associated  Seasonal fluctuations  Daily fluctuations due to P/S and respiration (night vs. day)  The pond as a fishery  Consequences of shallow depth  Aeration  Lack of macrophytes  Seasonal temperature tolerance of fish species  Very warm summers  Freezing in winter

Suggestions More suitable fish species More suitable fish species Habitat improvement Habitat improvement Changes in aeration Changes in aeration etc etc
