Abstract

Sixty juvenile Nile tilapia (Oreochromis niloticus) ranging from 30 — 40 g were divided randomly into 3 groups: control, group (A) and group (B) (in duplicate) with 10 fish in each group. The control group was fed basal diet. The second group (A) was given feed with addition of 0.5% Lantana camara extract. The third group (B) was given feed with addition of 2% Lantana camara extract. After 60 days, groups fed with diet mixed with different concentration of Lantana camara extract showed significant improvement in growth performance, hematological and biochemical parameters compared to the control group. At the end of the experiment fish were challenged with Streptococcus species, groups fed on diet mixed with different concentration of Lantana camara extract showed decrease in mortality rate compared to the control group. In conclusion, adding 2% Lantana camara to fish diet promote growth, improve fish health and reduce mortality in association with challenge with Streptococcus sp.
