Submersible container and in particular cage for aquatic culture, comprising a frame covered with a net provided with an access means. The frame is composed of at least three longitudinal members 1, 2, 3, 4 whose feet 5, 6, 7, 8 on the one hand and heads 13, 14, 15, 16 on the other hand are joined by tensioning devices 9, 10, 11, 12, 17, 18, 19, 20 in order to constitute a lower regular polygon and an upper regular polygon which are parallel, superposed and angularly offset, by virtue of an inclination of the longitudinal members, by an angle sufficient for two successive longitudinal members to overlap. Tensioning devices 21, 22, 23, 24 are provided between at least some of the feet and at least some of the heads. The longitudinal members 1, 2, 3, 4 consist of tubes which are closed at both ends but are provided with an opening 29 to the outside at the feet and are connected at the heads with the central pipe 34 of a compressed air source 35. <IMAGE> |
