Abstract

<abstract abstract-type="main" id="are12324-abs-0001"> <title>Abstract</title> <p>This feeding trial was conducted to determine the vitamin E requirement of sea cucumber (<italic>Apostichopus japonicus</italic>) and to study the effects of vitamin E on nonspecific immune parameters. Commercial sea cucumber diets supplemented with 0, 50, 100, 200, 500 or 1000 mg kg⁻¹ vitamin E were fed to juvenile sea cucumber (7.96 ± 0.01 g) for 60 days. Specific growth rate and total coelomocyte counts were maximized in sea cucumber fed diets supplemented with 100 mg kg⁻¹ vitamin E. Reactive oxygen species production was maximized at 50 mg kg⁻¹ vitamin E, whereas superoxide dismutase activity was the highest in sea cucumber fed diets supplemented with 100 mg kg⁻¹ vitamin E. The vitamin E concentration in the body wall of the sea cucumber increased as the vitamin E level in the diet increased. Analysis of specific growth rate and total coelomocyte counts of the sea cucumber indicated that 88–92 mg kg⁻¹ vitamin E is required for maximal growth and nonspecific immune responses of <italic>A. japonicus</italic> and that 114.7 mg kg⁻¹ vitamin E is required to minimize lipid peroxidation levels.</p> </abstract>
