Decay rates of F. psychrophilum phages during storage on fish feed pellets, in glycerol/buffer, and in buffer^a

Condition	Temp (°C)	Mean FpV-9 decay rate ± SD day−1b
Feeding pellets	20	0.036 ± 0.011*
Glycerol/buffer	−80	0.001 ± 0.001
Buffer	20	0.036 ± 0.002*

^aDecay rates were determined for F. psychrophilum phages during storage on fish feed pellets at 20°C, in glycerol/buffer at −80°C, and in buffer at 20°C.

^b*, a decrease in phage infectivity over time that was statistically significant (i.e., the slope was significantly different from 0; P < 0.05).
