Comparison of the physiological parameters of coral larvae between the control and treatment groups at different stages. (a) total carbohydrate, (b) total protein, (c) total lipid, and (d) chlorophyll a content. CF, newly released larvae; CM, Metamorphosis, control (CK) group; BM, Metamorphosis, bacteria inoculation (Bac) group; CP, Settlement, CK group; BP, Settlement, Bac group. Error bars represent means ± SE (n = 3 replicates. For total carbohydrate, total protein, and chlorophyll a, each replicate consisted of 60 coral larvae; for total lipid, each replicate comprised 120 larvae). Different letters denote significant differences (P < 0.05) as determined by the Student’s t-test
