Effect of diets containing Astaxanthin on continuous quality fish rainbow trout

The effect of diet containing astaxanthin on continuous quality fish rainbow trout for 8 weeks with synthetic astaxanthin concentrations of 100,60,40 mg per kg (mg / kg) were used for food. Trends and compare the quality of the samples, using chemical indicators, as well as color index L * a * b *)), in five separate time periods every 4 days (16,12,8,4,0) in typical refrigerator temperature were taken. The results showed that the highest levels of astaxanthin (100 mg) in the diet of rainbow trout compared with the amounts (40 mg) (60 mg) resulted in improved Meat quality status in terms of reducing the amount of PH, PV TBA and FFA in maximum storage time was due to the antioxidant properties of these compounds As the antioxidant and control groups were statistically significant (0/05> P) also can be colored based on the highest levels of astaxanthin for use in feed for the fish offered.
