PROBLEM TO BE SOLVED: To provide a land farming method and land farming facilities capable of reducing power cost because the pump power cost and blower power cost for aeration in breeding water purification treatment run into a large sum of money and press land farming management.SOLUTION: In fish and shellfish land farming facilities disposed of a portion or all of physical purification processing means, biological purification processing means, chemical purification processing means and electrochemical purification processing means, etc., the advection of water between respective purification treatment tanks including a breeding aquarium 1 is performed by a natural downward flow to the maximum, so that it is adjusted by water surface adjusting means. The water surface adjusting means can be made by a method for vertically adjusting an installation floor surface, and a method for increasing and decreasing a tank cross section and a tank effective depth using a tank effective capacity as a required capacity, etc. Also, aeration using a blower at the position with poor aeration efficiency and high diffusion water depth, which is conventionally widely used as aeration means, is reduced to the utmost.【課題】飼育水の浄化処理におけるポンプ動力費及び曝気用ブロワ動力費が多額になり、陸上養殖経営を圧迫するので、動力費の低減を可能とした陸上養殖方法及び陸上養殖施設を提供する。【解決手段】物理浄化処理手段、生物浄化処理手段、化学浄化処理手段及び電気化学浄化処理手段等を一部又は全てを配設した魚介類陸上養殖施設において、飼育水槽1を含めた、各浄化処理槽間の水の移流を最大限に自然流下とするために、水面調整手段で調整する。水面調整手段としては、設置床面を上下調整する方法、槽有効容量を所要容量として、槽断面積及び槽有効高さを増減する方法等で出来る。又、曝気手段として、従来において多用されている、曝気効率の悪い散気水深の大きい位置でのブロワによる曝気を極力に削減する構成とする。【選択図】図1
