Table 4: Movement of L. salmonis (lice) between initially infected and initially uninfected Atlantic salmon hosts. Day 0 post cohabitation (dpc) lice counts were done immediately before initiation of cohabitation. Number of fish indicates the number of fish lethally sampled to collect and count L. salmonis. There was no significant difference in the number of male lice/fish between groups (p<0.05). No female L. salmonis were observed to have switched hosts. |
