ABSTRACT:
A device for protecting shellfish dredge chain bags, featuring arcuate strips of reinforced rubber attached to the bottom side of the bag to cushion and separate the bag from abrasive action against the ocean floor when it becomes weighted with rocks and shellfish. These arcuate strips are cut from used vehicle tires and are attached to the chain bag in a manner that protects the forward edge and corners of the strip and the attaching device from catching on the ocean floor while allowing the longer portion of the reinforced rubber strip to trail beneath the chain bag.
