Shrimps with an initial weight of 11.10 ± 0.26 g were fed diets supplemented with 6.6% red pepper (RP), 2.4% marigold flower (MF), and 100 mg/kg synthetic astaxanthin (SA), each of which contained 100 mg/kg total carotenoid, and a control diet (BD), without carotenoid supplement for 60 days. Dietary carotenoid sources did not significantly affect the growth of the shrimps (P > 0.05). SA supplementation yielded the highest survival rate (92%), followed by RP (82%) and the other diets (75%) (P < 0.05). All dietary carotenoid sources provided higher carotenoid accumulation compared to the control group (P < 0.05), but the difference between them was not significant (P > 0.05). RP and SA resulted in a greater protein increase in shrimp muscle than MF (P < 0.05); however, lipid, ash, and water content were similar in all diet groups (P > 0.05).
