Table 5 Experimental design showing three test replicates for each combination of UV radiation exposure time and bacteria concentration

From: Ultraviolet radiation as disinfection for fish surgical tools

  Bacteria concentration
UV radiation duration None (negative control) Low Medium High
0 min (sham) - 3 3 3
2 min 3 3 3 3
5 min 3 3 3 3
15 min 3 3 3 3
  1. Tests involving R. salmoninarum included five test replicates. ‘None’ represents the negative control. Concentrations for ‘Low,’ ‘Medium,’ and ‘High’ are given in Table  4.
