Data showed as Mean ± SD, n = 12. AVS, acid‐volatile sulfur; ES, elemental sulfur; L, larval; LJ, large juvenile; SJ, small juvenile; TN, total nitrogen; TOC, total organic carbon; TS, total sulfur; TSS, total suspended solids. Values with different superscript letters mean significantly different (P < 0.05) among ponds, and same letters or without letters indicate no significant difference.
