Ammonia excretion rate (Table 5) was also significantly affected by diet and
postlarvae stages, and there was a significant interaction between this factors. Ammonia
excretion decreases from M to PL stages, in all diets, with higher values observed III 9–10
in organisms fed on MCD (treatment 2). PL and PL from treatments fed on Artemia 9 10
nauplii plus MCD (treatment 3) and Artemia nauplii plus MCD plus algae (treatment 4)
had the lowest total ammonia excretion rate with values between 0.04 and 0.07 mg
21 21 NH3-NH41 h mg dw
