摘要
真珠収穫後のアコヤガイ貝肉を主原料とし，海事作業から発生する貝掃除屑を加えてコンポスト化試験を行った。その結果，アコヤガイ貝肉は約 45 日の処理でコンポスト化が可能である事が分かった。また，貝掃除屑はコンポスト材料の通気性向上や，コンポストの肥料成分を増加させる効果が認められた。完熟したコンポストは，塩分を含むが，コマツナに対して肥料効果を示した。以上より，真珠養殖過程で廃棄される貝肉および貝掃除屑は，農業資材として有効活用できる事が示され，真珠養殖による環境負荷の低減につながると期待された。
Waste from activities associated with pearl culturing has become a cause of environmental deterioration on pearl farms. As part of our researches on reducing the environmental burden of Akoya pearl culturing, we investigated methods of composting pearl culture waste and effectively using this compost. We conducted composting tests using the soft body of Pinctada fucata after pearl harvesting as the main material, supplemented with debris resulting from sessile organisms removed during shell cleaning, and plant materials. We found that it was possible to convert Akoya oyster meat to mature compost in approximately 45 days without desalinization, and it was observed that including the debris of removed sessile organisms improved the aeration of the composting materials and increased the fertilizer components of the mature compost. Moreover, a seedling test showed that the mature oyster meat compost, when used at a rate of 10 g compost/1000 cm3 soil, improved the fresh weight of komatsuna. These results indicated that compost made from discarded oyster meat and the debris of removed sessile organisms can be effectively utilized in agriculture. The compost is also expected to reduce the environmental burden on pearl farms.
