ABSTRACT:
The present invention is directed to a novel device for reducing the friction which is generated when a trawl net is dragged along the ocean bottom. A trawl net, as it is being dragged in a forwardly direction, comes in contact with not only debris on the ocean floor but also with the substrate comprising the ocean floor, thus increasing the friction being applied to the net, which reduces the life of the net. The novel device contemplated herein is a device which is generally spherical in configuration, although somewhat elongated in one direction resembling a bobbin. The device is made of at least two parts which can be easily placed on the net webs or net lines, preferably at a rearwardly location with respect to the forward movement of the net. As the net is being pulled, the device, which is in contact with the ocean bottom, rolls, thereby reducing the contact between the net and the ocean bottom and also maintaining the net at a distance certain from the ocean bottom. This friction reducing device works particularly well with the type of trawl nets used in shrimp fishing.
