Amylase activities decreased from M to the intermediate stages and increased in III
PL in all treatments (Fig. 2b). Postlarvae fed on Artemia nauplii (treatment 1) and on 10
MCD (treatment 2) had higher amylase activity in M and PL than the postlarvae in III 1
other treatments, with amylase activity remaining high until PL when the postlarvae 3
were fed on the artificial diet.
