A drag (31, 131, 231, 331, 411) for harvesting seabed dwelling marine animals such as scallops, sea urchins and sea cucumbers. The drag (31, 131, 231, 331, 411) has a towing bar assembly (33, 133, 233, 333) connectable to a vessel via a warp, a drag frame with a front portion (39, 139, 239, 339) attached to the towing bar assembly (33, 133, 233, 333) and a rear portion (41, 141, 241, 341) which is attachable to a container (62, 162, 262, 362). The drag frame has a first side member (45, 145, 245, 345) and a second side member (47, 147, 247, 347), each having a lower seabed engaging surface (49, 149, 249, 349) and a sweeper (51, 151, 251, 351) comprising a resilient element having a fixed end which is operatively connected to the first side member (45, 145, 245, 345) and to the second side member (47, 147, 247, 347) and a free end (57, 157, 257, 357) which extends to a position planar with or extending beyond the lower seabed engaging surfaces (49, 149, 249, 349) of the first (45, 145, 245, 345) and second sides (47, 147, 247, 347) so as to sweep across the seabed, in use.

A fishing dredge (101) for making a catch of molluscs such as scallops. The fishing dredge has a dredge frame (104) with rotatable sea bed engaging members (105) arranged along the length of the sides of the dredge frame, a catch tray (103) for collecting an unearthed catch which is positioned in the dredge frame between the rotatable sea bed engaging members and sea bed engaging teeth (141) mounted on the dredge frame, the teeth being positioned at or near the front of the dredge frame for unearthing objects buried in the sea bed. The dredge frame is also fitted with a sorting mechanism (127) positioned between the sea bed engaging teeth (141) and the catch tray (103) for separating the catch from other unearthed objects and for moving the catch into the catch tray.

A raking element and an assembly of raking elements which may be arranged in a frame for a fishing dredge. The raking element comprises a length of resilient material which is shaped into a flat-spiral torsional spring with a predetermined torque at one end which is connectable at a first end to a fishing dredge frame. The second end of the length of resilient material forms a blade which digs into the sea bed, in use. The present invention provides an improved apparatus for raking or digging the seabed which improves the longevity of the blades whilst retaining an appropriate degree of resilience in the spring to allow it to be displaced when passing over a seabed obstacle.

A frame for a fishing dredge which has a sea bed engaging portion and an upper portion. Teeth are resiliently mounted on the frame to extend beyond the seabed engaging portion of the frame such that at least two of the teeth are resiliently mounted to move independently of one another. This feature allows the frame to move over obstacles encountered on the sea bed. The frame is also provided with funnelling means adapted to direct water into and through the frame in order to clear debris from the frame.

A fishing dredge and in particular to a belly (62) for a fishing dredge which comprises a sea bed engaging portion (63) and an upper portion (65). The sea bed engaging portion has a plurality of rotatably mounted rollers (47) and connectors (51) which together form a mesh such that at least one of the rollers forms part of the mesh. The belly (62) can roll across the sea bed thereby reducing the damage to the sea bed caused by dragging existing dredging apparatus across the sea bed.
