The results were presented in a repetitive manner. The authors can show only Tables 4,8 and 12 which encompassed all data in other tables.
My inquiry is related to the curious fact that final weights of Tilapia under different treatments were not shown. If one wants to calculate the total weight gain based on FI and FCR ( or FE) presented ,we will come up with figures ridiculously small for Tilapia after 16 weeks of raising ( plus 2 weeks for adaptation)
