Ascorbic acid (AA) is known to perform numerous biochemical and physiological functions especially for teleost fish. A feeding trial with a total of six hundred Caspian brown trout fingerlings (9.6±0.6 g) was conducted to determine the effect of AA on bone collagen and body composition of the Caspian brown trout (Salmo trutta caspius) as a valuable native teleost species. Five different diets containing 0, 50, 100, 200 and 400 mg kg-1 L-Ascorbyl-2-Polyphosphate were prepared as experimental treatments. Feeding of the fish was done in triplicates for 9 weeks in each treatment, each containing 40 Caspian brown trout fingerlings. The results showed significant differences in final weight, bone collagen and body composition of Caspian brown Trout fingerlings at the end of the feeding trial (p<0.05). Increase trends in AA amount of diets cause significant rise of weight (p<0.05), reaching to the final weight of 29.74±3.52 g at the 200 mg AA kg-1 treatment. Fish fed by 200 mg AA kg-1 diet had also the maximum amount of bone collagen; which had significant difference with control treatment (p<0.05). Besides, the highest ash content and fat concentrations were found in 50 mg kg-1 AA. Based on the broken line model, the optimum bone collagen and protein amounts were obtained at 247.54 and 250.55 mg AA kg-1 diet, respectively.
