Table 8.

Diversity index of gut bacteria of L. vannamei juveniles fed the five experimental diets for 8 weeks based on V4 sequences.

Items	D1	D2	D3	D4	D5
OTUs	283 ± 3.06^a	360 ± 2.00^c	390 ± 3.46^d	311 ± 1.73^b	522 ± 2.31^e
Chao 1	232 ± 11.82^a	323 ± 19.34^b	302 ± 17.87^b	252 ± 11.75^a	551 ± 20.85^c
Shannon	4.45 ± 0.01^a	4.94 ± 0.01^c	5.06 ± 0.01^d	4.81 ± 0.01^b	5.32 ± 0.02^e

Values are means ± SEM (n = 3 for OTUs and n = 10 for Chao1 and Shannon). Means in the same row without a common superscript letter differ, P < 0.05 (one-factor ANOVA, Duncan’s multiple range test). OTU, operational taxonomic unit; Chao1, Chao 1 index; Shannon, Shannon diversity index.
