Abstract
The aim of the present study was to evaluate the effects of diet with different microbial concentrations on the growth and length-weight relationship of Trichopodus trichopterus. For this aim a study was designed with four experimental treatments and the control to evaluate different microbial concentrations on growth and length-weight relationship. The counts of bacteria that were used for dietary supplementation were 1×104, 2×104, 3×104 and 4×104 CFU g-1 in T1, T2, T3 and T4 treatments, respectively. The results indicated that the use of 3×104 CFU g-1 concentration increased the length, and a positive allometric growth was observed. The higher length frequency was estimated in T3. The results indicated that the use of microbial additives with proper concentration causes different allometric growth.
