Abstract
This study evaluated dietary effects on growth performance, antioxidant capacity and metabolic
response of Nile tilapia Oreochromis niloticus fed diet with raw azolla (RA) and fermented azolla (FA) following
thermal stress. Fish were fed diet with different levels of RA [10% (10RA); 20% (20RA); 30% (30RA); 40%
(40RA)], FA [10% (10FA); 20% (20FA); 30% (30FA); 40% (40FA)] and a control diet (C) without azolla for ten
weeks. Growth and survival were monitored periodically. After rearing, fish were subjected to different temperature
(low: 25C, medium: 28C and high: 33C), and after a week, antioxidant capacity [superoxide dismutase (SOD),
glutathione peroxidase (GPx) and glutathione reductase(GR)] and metabolic response [glucose (Gluc), triglycerides
(Trig) and lactate (Lac)] were analyzed. The growth performance of fish fed diet with 20RA, 20FD and 30FD were
better as compared to C. In addition, fish fed with 10-40% FA had a better FCR as compared to C. Disregarding
levels, fish fed with FA showed better %Survival after the feeding trial (74%). No significant difference was found
on antioxidant capacity (SOD, GPx, GR) and metabolic response (Gluc, trig, Lac) of fish among treatments. The
activities of antioxidant capacity and metabolic response of Nile tilapia against thermal stress showed no interaction
effect between levels and temperature. Overall, inclusion of 20RA and 20-30FD in the diet could be a potential feed
ingredient in the diet of Nile tilapia.

Key words: Azolla, Antioxidants, Growth performance, Metabolic response, Nile tilapia, Thermal stress
