Values are means±SD (n=3 for survival rate, n=9 for dry weight). Values with different letters in a column indicate statistical differences among refrigerated storage treatments at the 5% levels by Duncan’s multiple range test. F values with asterisks are statistical significances in three-way ANOVA. *P≤0.05, **P≤0.01, ***P≤0.001 and NS (non-significance) = P>0.05.
