To provide a management method capable of reducing a toxic component in a water tank in order to prevent sudden death of fish and shellfish.SOLUTION: In a water tank storing fish and shellfish in the anesthetic state, a carbon dioxide concentration in the water tank is adjusted so as to urge a reaction to ammonium ion (NH) from ammonia (NH). Aeration means 30 can be used for adjustment of the carbon dioxide concentration.SELECTED DRAWING: Figure 2
