Each diet
was randomly fed to quadruplication groups of 40 shrimps (0.4 ± 0.01 g) reared in tanks. After an 8-week
feeding, the survival rate of shrimps fed with PS1 and PS3 were the highest among all treatments
(P < 0.05). The moisture content of shrimps fed with florfenicol was significantly lower than that of the
control group (P < 0.05).
