Abstract :– In present study, thiobarbituric acid insert ignore into journalissuearticles values(TBARS); properties insert ignore into journalissuearticles values(mg malonaldehyde kg-1); in rainbow trout insert ignore into journalissuearticles values(Oncorhynchus mykiss); fed with standard diets supplemented with canthaxanthin, astaxanthin and red pepper meal besides control group were investigated. In experiment, total of 375 rainbow trout with an initial average weight of 154 g were fed by dividing into 4 groups. The fishes were fed for 60 days with four diets insert ignore into journalissuearticles values(canthaxanthin70 mg kg-1, astaxanthin 50 mg kg-1, red pepper meal 765 mg kg-1 and control);. After the feeding period, the fishes in diet groups were evaluated in terms of total carotenoid concentration and TBARS. At the end of the trial, fodder supplemented with canthaxanthin, astaxanthin and red pepper meal caused carotenoid accumulation over 6 mg kg-1 concentration in the muscle tissues of the fishes. Frozen storage insert ignore into journalissuearticles values(at -30 ºC); of gutted, cleaned and glazed raw fishes for 12 months significantly reduced the total carotenoid concentration and TBARS value
