2. The escapement opening of the FFE must be diamond or oval in shape and
must remain unobstructed at all times. Diamond shaped FFEs must
measure at least 5 1/2" x 6 1/2" or 6" x 6", inside diameter. Oval shaped
FFEs must measure at least 9" x 5", inside diameter (see Figure 1).
3. The apex (narrow end) of the FFE must face the headrope of the trawl.
4. FFEs shall have at least three (3) legs and no more than four (4) legs and measure at least 12 inches in length.
5. The opening of the FFE shall be installed on the outside of the tailbag of the
trawl no further forward than 65% of the functional tailbag length from the
tailbag tie-off, (Table 1).
7. At least one FFE shall be installed in each tailbag.
8. The center of the FFE escapement opening must be installed no more than
19 meshes from the top centerline of the tailbag.
FFEs must be constructed from aluminum, steel, or stainless steel round bar or
tubing.
B. Eight inch (8") PVC "Sea Eagle" Fish Excluder:

the trawl.
2. The opening of the "Sea Eagle" shall be installed in the tailbag of the trawl
no further forward than 38% of the functional tailbag length from the tailbag
tie-off (Table 2).
3. At least one "Sea Eagle" shall be installed in each tailbag.

either side of the tailbag between 0 and 15 meshes from the top centerline
of the tailbag.

to the tailbag and to create an area of reduced water flow to allow for fish
escapement through the larger mesh outer netting.

A. These restrictions do not apply to a single test trawl net (try net) with a headrope
length of 16 feet or less, if it is operated under the following conditions: it is either
pulled immediately in front of another net or is not connected to another net in any
way; no more than one net is used at a time; and it is not towed as a primary net.
B. Channel nets, float nets, fixed nets, and butterfly nets are not required to use BRDs.
III. SPECIAL PROVISIONS:
Persons wishing to test BRD designs not covered by this proclamation may submit
BRD designs to the NCDMF, Morehead City office, for consideration of issuing a
time-limited Scientific and Educational Collecting Permit.
IV. DEFINITIONS: For the purposes of Proclamation SH-3-2001, the following terms are hereby defined:
Tailbag - That portion of the trawl net at which the trawl body taper ends and the straight extension begins, extending to the terminal end of the trawl.
