  • Supplemented diets with xanthophylls of T. erecta (zeaxanthin and lutein) produced an increase in the concentration of carotenoids in L. vannamei.

  • The shrimp pigment profile was predominated by astaxanthin. Zeaxanthin and lutein were recorded in low amounts.

  • It was concluded that the precursor xanthophylls were transformed and accumulated mainly as esterified astaxanthin by experimental subjects.

  • It was concluded that the greater accumulation of astaxanthin in the postlarvae produced a significant increase in survival.

  • According to other studies, the accumulation of astaxanthin in shrimp enhances physiological responses and the productive performance in culture.
