Penaeus japonicus postlarvae, reared under laboratory conditions, were fed an astaxanthin enriched diet to the investigate carotenoid metabolic capabilities during the postlarval development. Animals fed astaxanthin were found to absorb this carotenoid. The decrease of pigment concentration in the carotenoid starved group is related to the duration of the experimental feeding conditions; the carotenoid depletion depends upon the postlarval status at the starting point. As has been shown for adult prawns, the carotenoid pattern of postlarval stages, regardless of the diet, consists mainly of free and esterified astaxanthin; the relative amounts of these fractions undergo slight variations depending on the diet.
在实验室条件下饲养的日本对虾后期幼体，喂食富含虾青素的饲料，以研究后期幼体发育过程中的类胡萝卜素代谢能力。发现喂食虾青素的动物会吸收这种类胡萝卜素。类胡萝卜素饥饿组中色素浓度的降低与实验喂养条件的持续时间有关；类胡萝卜素的消耗取决于起始点的后期幼体状态。正如对成年对虾所显示的那样，后期幼体阶段的类胡萝卜素模式，无论饮食如何，主要由游离和酯化虾青素组成；这些组分的相对含量会因饮食而略有变化。
