Florida pompano is prominent for its high feed conversion efficiency, rapid growth, and high market demand. Xylanase, in comparison with protease, is not produced endogenously in Florida Pompano. The aim of this trial was to evaluate the effect of varying enzymes inclusion levels on the growth performance of the Florida Pompano. The basal diet was formulated to contain 40 % protein, then supplemented with commercial sources of protease or xylanase at multiple levels of 0.2, 0.4 and 0.6 g kg-3 to form a total of seven tested diets including the basal. Twenty fish were stocked with the initial weight of 8.30 ± 0.27 g in a 36 polypropylene tanks (0.8 m3) recirculating system. Five replicates were assigned for each diet, except the basal with 6. Pompano were fed according to the body weight (4.5 %- 7 %) four times a day. Feed input was adjusted according to visual observations and bi-weekly FCR. Overall, there was no statistically significant difference between diets and level of inclusion. However. there were significant differences between protease and xylanases. In conclusion, despite no statistical significance, protease and xylanase increased biological response of Florida pompano compared to the basal numerically. Therefore, inclusion levels will be dependent on the enzyme of choice.
