Apparatus for mounting on the deck of a vessel which is useful for dredging oysters or other marine animals from water bottoms which is comprised generally of the combination of (a) a dredge, (b) a tilt-frame with which the dredge is intimately associated in its function of lifting and dumping the contents of the dredge, after its retrieval from the water bottom, and (c) a conveyor, or conveyors, located below the tilt frame, the tilt frame being pivotally mounted above said conveyor, or conveyors, such that when the filled dredge is withdrawn from the water bottoms and rested upon the tilt-frame, the tilt frame will pivot and dump the contents of the dredge onto the conveyor, or conveyors, for transport to a location on the deck of the vessel for separation, assortment, grading or collection. Preferably, the dredge and tilt frame mechanisms are mounted on a portion of a conveyor which is extended over the edge of the deck of the vessel, and the extended portion of the conveyor is hinged to a fixed conveyor portion such that, when the dredge-tilt frame mechanism is not in operation, the end section of the conveyor which carries the dredge-tilt frame mechanisms can be hoisted, or raised above the deck of the vessel to facilitate movement of the vessel in canals, harbors, or other marine facilities.
