Cooling water was characterized by acute salinity fluctuations which adversely affected growth and survival of all species. Black drum was the only species which exhibited growth suitable for commercial production. However, black drum could not adapt to prolonged low salinities and suffered complete mortality. Striped mullet, stocked in the lake, survived the entire 2-year culture period, but growth rates were low. Pinfish and Florida pompano grew slowly and succumbed to low salinities while sea catfish and Atlantic spadefish could not tolerate low temperatures nor prolonged low salinity.
