| Research Abstract |
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.
