ABSTRACT:
The assembly comprises a frame-truss subassembly, to which are attached an internal subassembly for directing a flow of encountered water during dragging and a subassembly for collecting and discharging shellfish. An external subassembly is used for encasing the frame-truss subassembly together with the internal subassembly and the subassembly for collecting and discharging shellfish. The frame-truss subassembly includes a pair of lateral trusses, spaced at a distance commensurable with a width of the assembly. The internal subassembly includes an anterior panel with a forwards oriented concavity and a posterior panel with a backwards oriented concavity. The subassembly for collecting and discharging, disposed behind the internal subassembly includes a louver platform, a grid receptacle supported by the platform and a mechanism for topple over the grid receptacle. At least two sets of a multiplicity of hinged flaps are used.
