PURPOSE: A method for maintaining freshness of live fish using ion minerals and a method for culturing the live fish are provided to reduce the mortality rate of the live fish by adding the ion minerals to a fish farm and to enable a consumer to eat sliced raw fish which is fresh. CONSTITUTION: A method for maintaining freshness of live fish using ion minerals and a method for culturing the live fish include a step of adding mineral salts having pH 7 to a culture farm or an aquarium. The ion minerals include calcium, potassium, magnesium, zinc, iron, manganese, copper, and chlorine. The mineral salts are calcium chloride(CaCl_2), potassium chloride(KCl), magnesium chloride(MgCl_2), zinc chloride(ZnCl_2), ferric chloride(FeCl_2), manganese chloride(MnCl_2), cupric chloride(CuCl_2), calcium hydroxide(Ca(OH)_2), potassium hydroxide(KOH), magnesium hydroxide(Mg(OH)_2), zinc hydroxide(Zn(OH)_2), iron hydroxide(Fe(OH)_2), manganese hydroxide(Mn(OH)_2), or copper hydroxide(Cu(OH)_2). |
