No superscripts values in the same row represents that there was no significant difference (). ^aIBW means initial body weight; ^bFBW means final body weight; ^cRw means weight gain rate; ^dSRw means weight-specific growth rate; ^eICW means initial carapace width; ^fFCW means final carapace width; ^gRc means carapace width gain rate; ^hSRc means carapace width-specific growth rate.
