Mean (SD) values for water temperature (n = 26), dissolved oxygen concentration ( [O2], n = 26 ), individual weights at days 1, 14 and 26 (n = 2), total feed intake (TFI, n = 2), specific growth rate (SGR, n = 2) and feed conversion ratio (FCR, n = 2).

LSD = least significant difference.
Mean values with different superscripts are significantly different (ANOVA, p<0.05).
