Values represent means SD of six replicates and values in the same row with different letters are significantly different (P < 0.05).
a IBW (g shrimp1): initial body wet weight (g).
b FBW (g shrimp1): final body wet weight (g).
c WG (%): weight gain ¼ 100 (final body weight initial body weight)/initial body weight.
d SGR (% day1): specific growth ratio ¼ 100 (ln final body weight ln initial body weight)/total number of experimental days.
e FCR: feed conversion ratio ¼ g dry feed consumed/g wet weight gain.
f SR: survival rate (%) ¼ 100 final shrimp number/initial shrimp number
