The temperature in the tanks during the growth testwas monitored
on a daily basis. Otherwater quality parameters including pH, dissolved
oxygen (DO), alkalinity, total ammoniacal nitrogen (TAN), nitrite-N,
and nitrate-N were measured on the final day of the growth experiment.
Temperature was measured using a thermometer, whereas pH
and DO were measured using portable pH meter (Lutron YK2001PH,
Taiwan) and DO meter (Lutron DO-5519, Taiwan), respectively.
Alkalinity, TAN, nitrite-N and nitrate-N were measured according to
the Standard Method for the Examination of Water and Wastewater
