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.
