PROBLEM TO BE SOLVED: To make completely closed circulation type land breeding for abalones possible.SOLUTION: A completely closed circulation type land breeding system for abalones has: a foam separator 15 which removes suspension property organic matters contained in water in a breeding tank 2; an electrolytic chlorine generator 16 which converts persistent organic matters contained in the water in the breeding tank into easily decomposable organic matters; a biofilter apparatus 18 which nitrifies ammonia contained in the water in the breeding tank and converts it into nitrate; a denitrification apparatus 24 which denitrifies nitrate; and a sludge recovery tank 8 which collects sludge in the breeding tank. The breeding tank is provided with: a breeding tank body 3; a plurality of breeding baskets 4 which are arranged inside the breeding tank body while forming a water flow space 301 between a bottom of the breeding tank body and itself; a plurality of shelters 6 which are vertically arranged in the breeding basket respectively and are housed; air generating means 5 which are placed below the breeding baskets; and a plurality of sludge pockets 7 which are formed in parts on the bottom of the breeding tank. The denitrification apparatus is provided with: a denitrification area 25; and a circulation area 27 for circulating water that has passed the denitrification area 25 again in the denitrification area.
