摘要：
To provide a ferrous ion controlled release unglazing and a manufacturing method thereof, and a bivalve farming tool and an aquatic environment maintenance method using the unglazing which can release ferrous ion controlling and for a long term, can promote growth of phytoplankton, can raise amount of production of aquatic biology including bivalve, can suppress a reduction layer and can neutralize underwater acidic substances.SOLUTION: A ferrous ion controlled release unglazing 10 that solidified waste containing shell powder as a chief ingredient, clay as a binder and citric acid iron are burnt and the surface is porous can release ferrous ion controlling and for a long term, can promote growth of phytoplankton, can raise amount of production of aquatic biology including bivalve such as shor-necked clam 16, can suppress a reduction layer and can neutralize underwater acidic substances.SELECTED DRAWING: Figure 5【課題】水中に二価鉄イオンを長期間徐放出でき、植物プランクトン等の成長を促進させ、二枚貝を含む水棲生物の生産量を高められ、かつ還元層を抑制でき、水中の酸性物質を中和できる二価鉄イオン徐放出素焼物およびその製造方法ならびにこの素焼物を用いた二枚貝養殖具および水域環境保全方法を提供する。【解決手段】主成分の貝殻粉末と、バインダである粘土と、クエン酸鉄とを含む固化体を焼成した表面が多孔質の二価鉄イオン徐放出素焼物１０は、水中に二価鉄イオンを長期間徐放出でき、植物プランクトン等の成長を促進させ、アサリ１６などの二枚貝を含む水棲生物の生産量を高められ、かつ還元層を抑制でき、水中の酸性物質を中和することができる。【選択図】図５
