ABSTRACT:
A weedless turtle exclusion device which excludes turtles and like sized things from trawl nets and the like, while allowing the desired catch therethrough. A deflector, through which the catch passes en route to the net's tail bag or codend is situated between optional spacer rings in the trawling net and comprises a circular frame angularly affixed to the internal walls of the net's chute. Situated at upstream connection points are parallel deflection bars, running from the upstream connection points toward the downstream side of the frame. The bars are spaced allowing passage of the desired catch, e.g., shrimp, while narrow enough to deflect the larger turtles. They are unconnected on their downstream side and angled about five to thirty-five (5-35) degrees relative to the frame, forming an opening between their downstream end and the frame. In operation (FIG. 4) the catch and turtles are directed into the trawl via a large mouth opening into the chute area. The catch passes unhindered while the larger turtles are deflected off of the angled deflection bars and through a trap door out of the net. Seaweed, etc., under the action of the water current, passes through the chute, coming into contact with the deflection bars and normally wrapping around them. Due to the bars' configuration the water current forces the seaweed to slide down and off them passing through the opening, freeing the seaweed from the deflector and preventing clogging.
