Bivalve-seed collector, intended for collecting, protecting and raising seeds, both in natural rearing farms and in artificial beds. The collector comprises a plane and flexible support formed by a net or a grid 1-2, and a similarly flexible, continuous closure plate 4 which is preferably made from plastic, which bears on one of the surfaces of the net or of the grid and is connected to the threads or ribs of the latter. The assembly formed by the support and the plate may assume various shapes. <IMAGE> |
