Bacteriophage concentrations and volumes used in the study^a

Expt	Phage administration method	Vol or wt of phage solution or pellets	Phages (PFU) fish−1
1	Bath	2.5-liter bath (1 × 108 PFU ml−1)
	Oral intubation	100 μl	1 × 108
2	Phage-coated feed	2% of fish body wt (1 g feed fish−1)b	2.5 × 107

^aIn all experiments, phage stock concentrations were 1 × 10⁹ PFU ml⁻¹.

^bMean fish weight, measured prior to the start of experiment 2, was 50 g.
