Reduction of mercury level in cultured fish by compulsory swimming

通过强制游泳引导代谢活动降低养殖鱼类汞含量。对于红鳍金枪鱼，运动组的总汞浓度略有下降。在条纹缺乏的情况下，间隔游泳组的总汞含量略有下降。在孔雀鱼实验中，总汞和甲基汞水平与运动繁殖没有显著差异。根据这些结果，在目前情况下，通过养殖来降低养殖鱼类的汞含量可能是困难的。

Reduction of cultured fish mercury level was tried by compulsory swimming leading metabolic activity. In case of red seabream, total mercury concentration was slightly decreased in exercising group. In case of striped lack, one of pelagicfishes, total mercury level was slightly decreased by interval swimming group. In case of guppy experiment, total mercury and methylmercury levels showed no significant difference with exercising breeding. According to these results, reduction of mercury level of cultured fish by exercising breeding may be difficult in the current situation.
