The effects of different levels of vitamin c added in the diet of brook trout (34.65±0.45 g) for 10 weeks on growth,condition factor (cf),feed conversion ratio (fcr) and meat composition were investigated. fish samples were fed on nutrition added with 0,100,500 and 1.000 mg/kg of l-ascorbyl-2-monophosphate (amp). experiment was performed using a 3×4 completely randomized factorial design. according to the results,weights at the end of experiment demonstrated differences between the treatments. the highest value was obtained as 98.34±0.10 g with the nutrition added with 500 mg/kg of vitamin c,while the lowest value was observed as 92.40±0.19 g in the control group. differences between different levels of vitamin c were found statistically significant (p<0.01). differences between treatment groups regarding feed conversion ratio were also found statistically significant (p<0.01). the best feed conversion ratio was determined as 1.42±0.11 on average in the group fed on nutrition with 500 mg/kg vitamin c addition,and the lowest was as 1.68±0.22 in the control group. according to the results of the analysis on the characteristics of meat composition,condition factor was found statistically insignificant (p>0.05),while hepatosomatic and viscerosomatic indices were statistically significant (p<0.05).
