P values (*P<0.05, **P< 0.01, ***P<0.001) are from F test; degrees of freedom are (4,99) for the density treatment,(1,99) for the oxygen treatment, and (4,99) for the density/oxygen interaction.

Symbols are defined in Tables 2 and 3. Values of Ppro, Pper and Pzero in this ANOVA were derived using a profile drag coefficient of 0.02, but the overall statistical results were unchanged by use of the higher coefficient of 0.2.
