| L-ascorbyl-2-polyphosphate (ApP) was used as a vitamin C source to study the ascorbic acid (AA) requirements for the early postlarval stages of white shrimp (<i>Penaeus vannamei</i>). First the stability of ApP in the diets was determined: ApP losses after pelletizing and 10 min immersion in seawater were 25-35% and 30%, respectively. Semipurified diets with five levels of ApP (0, 20, 40, 100 and 200 mg kg<sup>-1</sup> expressed as active AA were fed <i>ad libitum</i> to <i>P. vannamei</i> (PL-14 stage, mean dry weight 0.73 mg) for 26 days. Each treatment was run in five replicates. No significant differences in growth were observed among treatments after 26 days of feeding. As of day 19 of feeding, increased... |

| Postlarvae of tiger shrimp, <i>Penaeus monodon</i> (Fabricius), were fed semipurified diets supplemented with various levels of astaxanthin (AX) and ascorbic acid-polyphosphate (ApP): three groups were fed 230 mg AX kg<sup>-1</sup> diet combined with 100, 1700 and 3400 mg ascorbic acid (AA) kg<sup>-1</sup> diet, respectively; two diets contained 810 mg AX kg<sup>-1</sup> mixed with 200 and 1700 mg AA kg<sup>-1</sup>, respectively. Each treatment was run in four replicates. Incorporated levels of AA and AX, production output, and physiological condition were recorded after 4 weeks feeding. Whole-body AA (21-47 µg<sup>-1</sup>) and AX concentrations (19-35 µg<sup>-1</sup>)... |
