Title 50 - Wildlife and Fisheries
A. Extended Funnel. 1. Description. The extended funnel BRD consists of an extension with large-mesh webbing in the center (the large-mesh escape section) and small-mesh webbing on each end held open by a semi-rigid hoop. A funnel of small-mesh webbing is placed inside the extension to form a passage for shrimp to the codend. It also creates an area of reduced water flow to allow for fish escapement through the large mesh. One side of the funnel is extended vertically to form a lead panel and area of reduced water flow. There are two sizes of extended funnel BRDs, a standard size and an inshore size for small trawls. 2. Minimum Construction and Installation Requirements for Standard Size. (a) Extension Material. The small-mesh sections used on both sides of the large-mesh escape section are constructed of 1 (b) Large-Mesh Escape Section. The large-mesh escape section is constructed of 8 to 10 inch (20.3 to 25.4 cm), stretched mesh, webbing. This section is cut on the bar to form a section that is 15 inches (38.1 cm) in length by 95 inches (241.3 cm) in circumference. The leading edge is attached to the 6 (c) Funnel. The funnel is constructed of 1 (d) Semi-Rigid Hoop. A 30-inch (76.2-cm) diameter hoop constructed of plastic-coated trawl cable, swaged together with a (e) Installation. The extended funnel BRD is attached 8 inches (20.3 cm) behind the posterior edge of the TED. If it is attached behind a soft TED, a second semi-rigid hoop, as prescribed in paragraph A.2.(d), must be installed in the front section of the BRD extension webbing at the leading edge of the funnel. The codend of the trawl net is attached to the trailing edge of the BRD. 3. Minimum Construction and Installation Requirements for Inshore Size. (a) Extension Material. The small-mesh sections used on both sides of the large-mesh escape section are constructed of 1 (b) Large-Mesh Escape Section. The large-mesh escape section is constructed of 8 to 10 inch (20.3 to 25.4 cm), stretched mesh, webbing. This section is cut on the bar to form a section that is 15 inches (38.1 cm) by 75 inches (190.5 cm) in circumference. The leading edge is attached to the 6 (c) Funnel. The funnel is constructed of 1 (d) Semi-Rigid Hoop. A 24-inch (61.0-cm) diameter hoop constructed of plastic-coated trawl cable, swaged together with a (e) Installation. The extended funnel BRD is attached 8 inches (20.3 cm) behind the posterior edge of the TED. If it is attached behind a soft TED, a second semi-rigid hoop, as prescribed in paragraph A.3.(d), must be installed in the front section of the BRD extension webbing at the leading edge of the funnel. The codend of the trawl net is attached to the trailing edge of the BRD. B. Expanded Mesh. The expanded mesh BRD is constructed and installed exactly the same as the standard size extended funnel BRD, except that one side of the funnel is not extended to form a lead panel. C. Fisheye. 1. Description. The fisheye BRD is a cone-shaped rigid frame constructed from aluminum or steel rod of at least 2. Minimum Construction and Installation Requirements. The fisheye has a minimum opening dimension of 5 inches (12.7 cm) and a minimum total opening area of 36 square inches (91.4 square cm). The fisheye must be installed at the top center of the codend of the trawl to create an opening in the trawl facing in the direction of the mouth of the trawl no further forward than 11 ft (3.4 m) from the codend drawstring (tie-off rings) or 70 percent of the distance between the codend drawstring and the forward edge of the codend, excluding any extension, whichever is the shorter distance. In the Gulf EEZ only, when the fisheye BRD is installed in this position, no part of the lazy line attachment system (i.e., any mechanism, such as elephant ears or choker straps, used to attach the lazy line to the codend) may overlap the fisheye escape opening when the fisheye is installed aft of the attachment point of the codend retrieval system. D. Gulf fisheye. 1. Description. The Gulf fisheye BRD is a cone-shaped rigid frame constructed from aluminum or steel that is inserted into the top center of the codend, or is offset not more than 15 meshes perpendicular to the top center of the codend, to form an escape opening. 2. Minimum Construction and Installation Requirements. The Gulf fisheye is a cone-shaped rigid frame constructed of aluminum or steel rods. The rods must be at least E. Jones-Davis. 1. Description. The Jones-Davis BRD is similar to the expanded mesh and the extended funnel BRDs except that the fish escape openings are windows cut around the funnel rather than large-mesh sections. In addition, a webbing cone fish deflector is installed behind the funnel. 2. Minimum Construction and Installation Requirements. The Jones-Davis BRD must contain all of the following. (a) Webbing extension. The webbing extension must be constructed from a single piece of 1 (b) 28-inch (71.1-cm) cable hoop. A single hoop must be constructed of (c) 24-inch (61.0-cm) hoop. A single hoop must be constructed of either number 60 twine 80 inches (203.2 cm) in length or (d) Funnel. The funnel must be constructed from four sections of 1 (e) Attachment of the funnel in the webbing extension. The funnel must be installed two meshes behind the leading edge of the extension starting at the center seam of the extension and the center mesh of the funnel's top section leading edge. On the same row of meshes, the funnel must be sewn evenly all the way around the inside of the extension. The funnel's top and bottom back edges must be attached one mesh behind the 28-inch (71.1-cm) cable hoop (front hoop). Starting at the top center seam, the back edge of the top funnel section must be attached four meshes each side of the center. Counting around 60 meshes from the top center, the back edge of the bottom section must be attached 4 meshes on each side of the bottom center. Clearance between the side of the funnel and the 28-inch (71.1-cm) cable hoop (front hoop) must be at least 6 inches (15.2 cm) when measured in the hanging position. (f) Cutting the escape openings. The leading edge of the escape opening must be located within 18 inches (45.7 cm) of the posterior edge of the turtle excluder device (TED) grid. The area of the escape opening must total at least 864 in2 (5,574.2 cm2 ). Two escape openings 10 meshes wide by 13 meshes deep must be cut 6 meshes apart in the extension webbing, starting at the top center extension seam, 3 meshes back from the leading edge and 16 meshes to the left and to the right (total of four openings). The four escape openings must be double selvaged for strength. (g) Alternative Method for Constructing the Funnel and Escape Openings. The following method for constructing the funnel and escape openings may be used instead of the method described in paragraphs F.2.d., F.2.e., and F.2.f. of this section. With this alternative method, the funnel and escape openings are formed by cutting a flap in each side of the extension webbing; pushing the flaps inward; and attaching the top and bottom edges along the bars of the extension webbing to form the v-shape of the funnel. Minimum requirements applicable to this method include: (1) The funnel's top and bottom back edges must be attached one mesh behind the 28-inch (71.1-cm) cable hoop (front hoop); (2) clearance between the side of the funnel and the 28-inch (71.1-cm) cable hoop (front hoop) must be at least 6 inches (15.2 cm) when measured in the hanging position; (3) the leading edge of the escape opening must be located within 18 inches (45.7 cm) of the posterior edge of the turtle excluder device (TED) grid; and, (4) the area of the escape opening must total at least 864 in2 (5,574.2 cm2 ). To construct the funnel and escape openings using this method, begin 3 (h) Cone fish deflector. The cone fish deflector is constructed of 2 pieces of 1 (i) 11-inch (27.9-cm) cable hoop for cone deflector. A single hoop must be constructed of (j) Installation of the cone in the extension. The cone must be installed in the extension 12 inches (30.5 cm) behind the back edge of the funnel and attached in four places. The midpoint of a piece of number 60 twine 4 ft (1.22 m) in length must be attached to the apex of the cone. This piece of twine must be attached to the 28-inch (71.1-cm) cable hoop at the center of each of its sides; the points of attachment for the two pieces of twine must be measured 20 inches (50.8 cm) from the midpoint attachment. Two 8-inch (20.3-cm) pieces of number 60 twine must be attached to the top and bottom of the 11-inch (27.9-cm) cone hoop. The opposite ends of these two pieces of twine must be attached to the top and bottom center of the 24-inch (61-cm) cable hoop; the points of attachment for the two pieces of twine must be measured 4 inches (10.2 cm) from the points where they are tied to the 11-inch (27.9-cm) cone hoop.
