    JCO,

    I’m very new to aquaponics, so if the answer to my question is obvious to all, that’s why.

    You said: “In Nile Tilapia and possibly most Tilapia that temperature would be within a narrow range around 95°F (35°C) to 97°F (36°C) for said period of time then the thermostat should be set to a temperature range no lower than 80°F (27°C) and no higher than 85°F (29°C).”

    How long do you treat the Tilapia at the high temperature? Two days, between 10-12 days after yolk sac absorption?

    By setting the thermostat to 80-85°F, will the water temperature actually be 95-97°F? Sounds to me like your temperature control might need improvements.

      JonC,

      Sorry it took forever for me to reply, however my health and life in general have been keeping me busy. I have revised a portion of the post to this in hopes it will clear up your confusion:-

      Exposure to an elevated temperature, as described below, for fry immediately after yolk sac absorption for a period of 10 to 12 days can increase the proportion of male to female ratio substantially.
