Effect of Leucas aspera Against Aeromonas hydrophila in Nile Tilapia (Oreochromis niloticus): Immunity and Gene Expression Evaluation
The present study addressed the effects of Leucas aspera enriched diet in Nile tilapia. Three hundred Nile tilapia were fed Leucas aspera as follows: 0 g kg-1 L. aspera (C-control), 5 g kg-1 L. aspera (T1), 10 g kg-1 L. aspera (T2) and 15 g kg-1 L. aspera (T3). After 30 days of feeding, significant...

After 21 days of challenge, highest survival rate (70%) was observed in fish fed the T3 diet followed by fish fed T2 diet (65%). Serum immunological parameters such as phagocytosis, alternative complement activity, respiratory burst activity and lysozyme activity were significantly (P<0.05) enhanced in fish fed all inclusion levels of L. aspera with the maximum activity in fish fed the T2 diet. Hematological parameters were significantly (P<0.05) higher in all groups fed L. aspera diets vs. control fed fish.
