3.3. Survival rate and cumulative mortality
In infected fish fed with 5% and 10% R. apiculata enriched diets the
survival rate was higher (85% and 80%); it declined to 65%, with 1%
diet. However, the cumulative mortality was the minimum (10%) in infected fish fedwith basal control diet (Fig. 10). Similarly, a lowcumulative
mortality of 15% and 20% was observed when fed with 5% or 10%
supplementation diets. The infected un-treated group suffered a high
cumulative mortality of 90%, while the un-infected group fed with control
basal diet did not suffer mortality (Fig. 11).
