Abstract
An apparatus for aquaculture, in particular for rearing water-dwelling fry, which is intended to be placed preferably in flowing water or water with some wave formation, is kept floating with the aid of floating elements, and consists of a breeding space formed by two end walls, two side walls, and a bottom plate, where the side walls have a number of openings. A flow-intensifying member is arranged in the upper edge of the breeding space. The size of the openings is adjustable.
