寻找具有成本效益的策略来减少镉（Cd）的吸收是对水产养殖业消费者食品安全的重大关注。本试验研究了钙（Ca）对共养鲢鱼（Hypophthalmichthys molitrix）和三角帆贻贝（Hyriopsis cumingii）镉吸收的保护作用。结果表明，钙对鲢鱼肌肉（48% - 72%）、鱼鳃（51% - 57%）、肝脏（52% - 81%）和肾脏（54% - 81%）以及三角帆贻贝足（8% - 32%）和内脏（40% - 47%）的Cd吸收量有显著降低（p< 0.001） （p< 0.05）。结果表明，钙处理是减少水产养殖中镉积累的有效手段。由于钙经常被用于提高三角帆贻贝生产的珍珠的质量，因此共养食用鱼的质量可能会因为潜在地减少镉的吸收而得到改善。
Discovering cost effective strategies to reduce cadmium (Cd) uptake is of great concern for consumer food safety in the aquaculture industry. This study investigated the protective effects of calcium (Ca) on Cd uptake in co-cultured silver carp (Hypophthalmichthys molitrix) and triangle sail mussel (Hyriopsis cumingii). The results show that Ca—depending on its applied concentration—caused a significant decrease in the Cd uptake into muscle (by 48 %–72 %), gills (by 51 %–57 %), liver (by 52 %–81 %) and kidney (by 54 %–81 %) of silver carp (p< 0.001), as well as foot (by 8 %–32 %) and visceral mass (by 40 %–47 %) of triangle sail mussels (p< 0.05). The results indicate that Ca treatment is an effective means of reducing Cd accumulation in aquaculture. Since Ca is often used to increase the quality of pearls produced by triangle sail mussel, the quality of co-cultured edible fish might improve as a consequence of the potentially reduced Cd uptake.
