摘要：
PROBLEM TO BE SOLVED: To provide technologies for providing an artificial environment for breeding semisulcospira libertinas.SOLUTION: In breeding semisulcospira libertinas as baits for larvae of fireflies, limestones whose diameter is from 5 cm to 10 cm for eluting shell components for young shells are disposed within a water tank in which water temperature is retained from 15°C to 30°C and water is circulated by a filter device. Further, artificial aquatic plants to which diatom is easily attached as baits for the young shells, fallen leave of magnolia obovata or formula feed pellets for fish and herbivores are fed to the water tank to breed the semisulcospira libertinas.【課題】人工的なカワニナ類の飼育環境を実現するための技術を提供する。【解決手段】蛍幼虫の餌となるカワニナ類の飼育する際に、水温を摂氏１５度乃至３０度に維持し、濾過装置を用いて循環させた水槽中内で、稚貝の殻成分を溶出する直径５乃至１０ｃｍ程度の石灰石を配置し、稚貝の餌となる珪藻の付着が容易な人工水草、朴木の落葉または魚や草食動物用の配合飼料ペレットを供給して、飼育するようにした。【選択図】図１
