PROBLEM TO BE SOLVED: To provide a land forcing aquaculture method of eliminating the need for forming aquaculture holes and enabling shellfishes to be freely opened for receiving sunlight, the forcing aquaculture method that makes illumination electrically to thereby enable growing even at night.SOLUTION: A land forcing aquaculture method is provided which is not an aquaculture hole method to put spats in aquaculture holes, in which the shellfishes of Tridacna crocea 6 are exposed and cultivated in a land aquarium 1, and after the growth, the shellfishes are harvested and commercialized in an unhurt state without being damaged in the shellfishes and contents. The forcing aquaculture method makes illumination electrically by light L and promotes the growth when the sunlight cannot be received, and the illumination is electrically made by the light L even at night when the sunlight cannot be received, and thereby symbiosis algae are grown and the Tridacna crocea 6 growing with this as bait is grown in a short term, resulting in enabling the forcing aquaculture.SELECTED DRAWING: Figure 5【課題】養殖穴を形成する必要が無く、自由に貝を開けて太陽光を受光する陸上養殖方法において、電気的に照光して夜間も成長可能とした、促成養殖方法を提供する。【解決手段】養殖穴の中に稚貝を入れる養殖穴方法ではなく、ヒメジャコ６の貝が露出した状態で陸上の水槽１中で養殖し、成長後に貝や中身を傷付けずに無傷の状態で収穫し商品化する方法において、太陽光を受光できない時に、電気的にライトＬで照光して成長を促す促成養殖方法でり、太陽光を受光できない夜間でも、電気的にライトＬで照光することによって、共生藻が成長し、これを餌にして成長するヒメジャコ６も短期間に成長し、促成養殖が可能となる。【選択図】図５
