PURPOSE:To enable high-density packing of fish and shellfish and enable the culture and feeding of fish and the change of fish meat quality, etc., by cutting the spinal cord in the backbone of a fish and shellfish, etc., to paralyze the fish and shellfish and decrease the oxygen consumption of the fish, etc. CONSTITUTION:The spinal cord in the backbone 2 of a fish or shellfish body 1, etc., is cut to paralyze the fish or shellfish 1, etc., decrease the oxygen consumption of the fish, etc., disable the violent struggle and leap of the fish, etc., and enable the transportation or culture of the fish and shellfish 1, etc., in high density. As an alternative, the temperature of the body of the fish or shellfish 1 is lowered to about 0 deg.C at a stroke to vary the nature of the fish meat in living state or microorganisms such as viruses in an aqueous solution in a water tank for the transportation or culture of a fish or shellfish 1 is eliminated by using a filtration tool 16 composed of a pair of gas-permeable electrodes 20 having terminals 19 at both ends and a gas-permeable insulating material 18 such as filter paper or sieve placed between the electrodes and immersing the filtration tool in the solution. |
