Finally we evaluated the ability of a bacteria pathogen, V.
anguillarum, to grow in the presence of rainbow trout skin mucus
from the three different experimental groups. Surprisingly, the PTS
skin mucus elicited different V. anguillarum growth curves compared
to the skin mucus collected from the PTNS group. Whereas after 8 h,
PTS mucus allowed greater V. anguillarum growth, after 24 h, PTS
mucus inhibited V. anguillarum growth by 20% compared to the 10% recorded
in the PTNS group. Thus, either the presence of salt in the skin
mucus or the actual mucus antimicrobial properties of the PTS skin
mucus are beneficial against bacterial pathogen growth. This is again,
a novel explanation as to why salt can improve fish health during live
transportation of fish
