Effect of Dietary Supplementation of Green Tea (Camellia Sinensis) on Growth, Body Composition and Serum Biochemistry of the Asian Seabass, Lates calcarifer Fingerlings

The current study aimed to evaluate the effect of dietary supplementation of different levels of green tea (Camellia sinensis) on growth performance, body composition and serum biochemistry of Asian Sea bass, Lates Calcarifer. Therefore, Asian sea bass fingerlings with an initial body weight of 43.20 ± 0.11 grams were randomly assigned into 3 groups as triplicates. Fish were tested with three experimental diets of similar protein content (514.8 ± 0.06 g/kg-1) and energy (48.4 ± 0.02 kcal/g) for 90 days. The first diet was treated as control without any inclusion of additives. The other two diets were mixed with green tea of 10 g/kg-1 and 20 g/kg-1 respectively. The results clearly shown a significant (P<0.05) improvement of growth performance in all fish fed with green tea as dietary additive when compared with control, whereas the maximum performance is attained from the first treatment with lower dose (10 g/kg-1) of green tea additive. the current study can concluded that, the dietary inclusion of low levels of green tea as feed additives has relatively improved the growth performance, feed utilization and general health without any adverse effects on biochemical profile of Asian sea bass (Lates calcarifer).
