Alteration in the relative percentage of survival (RPS) rate of rainbow
trout (Oncorhynchus mykiss) exposed to 5, 10 and 25 mu g ml(-1)
levamisole for 2 h against Yersinia ruckeri was investigated. The
average weight of the 120 fish used in this study was 6.3g. Upon
challenge with a virulent strain, the relative survival percentage of
respectively 83.3\%, 86.7\% and 76.6\% was recorded. The results suggest
that the application of levamisole in fish farms could increase
resistance to infection of fish and offer economic benefits. | |
