Currently, great progress in the artificial propagation of commercially important portunid crabs of the genus has been achieved, and various methods have been adopted in mass-scale hatchery activities. This study analyzed the biological testing of formulated diets with different dose supplementations of vitamin E for the broodstock of female blue swimming crabs, (Linnaeus, 1758) Female crab samples were collected from the coastal region of Padang, West Sumatra. The method used in this study was completely randomized design, with four treatment regimens (n=5 crabs each) of dietary vitamin E (0, 300, 600, and 900 IU/kg formulated diets). The results show that the supplementation of vitamin E in the formulated diet had a significant effect (P <0.05) on the absolute weight growth, carapace length and carapace width. Supplementation of vitamin E on in formulated diet causes broodstock blue swimming crab molting, with a percentage value of 40-80% on day 20 and 20% on day 30, with a 100% survival rate.
目前，在具有商业重要性的梭子蟹属螃蟹的人工繁殖方面已取得了巨大进展，并且在大规模孵化活动中采用了各种方法。本研究分析了不同剂量维生素E添加量的配合饲料对雌性蓝蟹（Callinectes sapidus，林奈，1758）亲体的生物学测试。雌性蟹样本采自西苏门答腊省巴东的沿海地区。本研究采用的方法是完全随机设计，有四种饮食维生素E处理方案（每组n = 5只螃蟹）（0、300、600和900 IU/kg配合饲料）。结果表明，配合饲料中添加维生素E对绝对体重增长、甲壳长度和甲壳宽度有显著影响（P <0.05）。配合饲料中添加维生素E会使亲体蓝蟹蜕壳，在第20天蜕壳百分比为40 - 80%，第30天为20%，存活率为100%。
