The device for gathering seed oysters comprises collectors in the form of discs 4, separated by spacers 5, threaded onto an elongate tube-shaped floating structure 1 which is ballasted at its lower part 3. The device for gathering seed oysters may be in the form of a line consisting a set of gathering devices joined together by linkage means. The invention also relates to the collector discs 4, whose surfaces are roughened and which comprise, at the centre, a mortise allowing them to be driven on an appropriate apparatus for the emptying operation. <IMAGE> |
