NMFS announces that lobster trap/pot and anchored gillnet fishermen must comply with required gear modifications (see below) in a DAM zone east of Chatham, MA, March 7 through March 21, 2008

(from E-mail dated March 1, 2008:)

Dear ALWTRT Member or Interested Party:

On February 25, 2008, six North Atlantic right whales were sighted east of Chatham, Massachusetts, in the proximity of 41º 40' N. latitude and 69º 40' W. longitude which resulted in NOAA’s National Marine Fisheries Service (NMFS) taking action under the Dynamic Area Management (DAM) program to provide protection for this aggregation of right whales.

NMFS announces that lobster trap/pot and anchored gillnet fishermen must comply with the required gear modifications (see below) in an area east of Chatham, Massachusetts, effective 0001 hours March 7, 2008, through 2400 hours March 21, 2008. The regulations apply to lobster trap/pot and anchored gillnet fishermen in an area totaling approximately 1,238 square nautical miles. Once effective, all anchored gillnet and lobster trap/pot gear must comply with the gear restrictions required to continue fishing in a DAM zone for the restricted time period. In addition, NMFS requires that no additional gear be set in the DAM zone during the 15-day period unless that gear has been modified accordingly.

The coordinates for the DAM Zone effective from 0001 hours March 7, 2008 , through 2400 hours March 21, 2008 , are as follows:
42º 02´ N., 69º 24´ W. (NW Corner)
42º 02´ N., 69º 11´ W.
41º 19´ N., 69º 11´ W.
41º 19´ N., 69º 59´ W., then follow the northern Nantucket coastline westward to
41º 19´ N., 70º 04´ W.
41º 19´ N., 70º 09´ W.
41º 39´ N., 70º 09´ W., then follow the Cape Cod coastline eastward to
41º 45´ N., 69º 56´ W.
41º 45´ N., 69º 33´ W.
41º 49´ N., 69º 24´ W.
42º 02´ N., 69º 24´ W. (NW Corner)

Special note for gillnet fishermen: a portion of this DAM zone overlaps the Northeast Multispecies year-round Closed Area I found at 50 CFR 648.81(f)(a), and the Northeast Multispecies seasonal Gulf of Maine Rolling Closure Area I for found at 50 CFR 648.81(f)(i). Due to these closures, sink gillnet gear is prohibited from these portions of the DAM zone.

A permit holder letter including the DAM zone coordinates and restrictions is now posted on the ALWTRP website (http://www.nero.nmfs.gov/whaletrp) under “What’s New.” An outreach supplement showing the DAM zone overlayed onto a Nautical Chart is also available. NMFS will be notifying the public of the DAM zone by issuing radio announcements, working through appropriate media, distributing the permit holder letter to affected fishermen, as well as other means. As an ALWTRT member or interested party, NMFS appreciates your assistance in spreading the word about the DAM zone and its gear restrictions.

To obtain the DAM regulations in their entirety, please call 978-281-9300 x6505. In addition, these regulations are available by accessing the ALWTRP web page (http://www.nero.nmfs.gov/whaletrp/) and going to “The Plan” and “Elements of the Plan.” If you have any questions regarding these regulations, please call 978-281-9300 x6505 or the ALWTRP Coordinator at the number below. If you have questions about the gear requirements for this DAM zone, you may also contact John Higgins ( or 207-677-2316).

DAM Program Gear Requirements

In addition to those gear modifications currently implemented under the ALWTRP at 50 CFR 229.32, the following gear modifications are required in the DAM zone. If the requirements and exceptions for gear modification in the DAM zone, as described below, differ from other ALWTRP requirements for any overlapping areas and times, then the more restrictive requirements will apply in the DAM zone. Please note that the below provides a summary of the DAM Program gear requirements and is not a substitute for the ALWTRP regulations.

Lobster Trap/Pot Gear

Fishermen utilizing lobster trap/pot gear within the portions of Northern Inshore State Lobster Waters, Northern Nearshore Lobster Waters, and Stellwagen Bank/Jeffrey’s Ledge Restricted Area that overlap with the DAM zone are required to utilize all of the following gear modifications while the DAM zone is in effect:

  1. Groundlines must be made of either sinking or neutrally buoyant line. Floating groundlines are prohibited;
  2. All buoy lines must be made of either sinking or neutrally buoyant line, except the bottom portion of the line, which may be a section of floating line not to exceed one-third the overall length of the buoy line;
  3. Fishermen are allowed to use two buoy lines per trawl; and
  4. A weak link with a maximum breaking strength of 600 lb (272.4 kg) must be placed at all buoys.

Fishermen utilizing lobster trap/pot gear within the portion of the Offshore Lobster Waters Area that overlap with the DAM zone are required to utilize all of the following gear modifications while the DAM zone is in effect:

  1. Groundlines must be made of either sinking or neutrally buoyant line. Floating groundlines are prohibited;
  2. All buoy lines must be made of either sinking or neutrally buoyant line, except the bottom portion of the line, which may be a section of floating line not to exceed one-third the overall length of the buoy line;
  3. Fishermen are allowed to use two buoy lines per trawl; and
  4. A weak link with a maximum breaking strength of 1,500 lb (680.4 kg) must be placed at all buoys.

Anchored Gillnet Gear

Fishermen utilizing anchored gillnet gear within the portions of Other Northeast Gillnet Waters Area and Stellwagen Bank/Jeffrey’s Ledge Restricted Area that overlap with the DAM zone are required to utilize all the following gear modifications while the DAM zone is in effect:

  1. Groundlines must be made of either sinking or neutrally buoyant line. Floating groundlines are prohibited;
  2. All buoy lines must be made of either sinking or neutrally buoyant line, except the bottom portion of the line, which may be a section of floating line not to exceed one-third the overall length of the buoy line;
  3. Fishermen are allowed to use two buoy lines per string;
  4. Each net panel must have a total of five weak links with a maximum breaking strength of 1,100 lb (498.8 kg). Net panels are typically 50 fathoms (91.4 m) in length, but the weak link requirements would apply to all variations in panel size. These weak links must include three floatline weak links. The placement of the weak links on the floatline must be: one at the center of the net panel and one each as close as possible to each of the bridle ends of the net panel. The remaining two weak links must be placed in the center of each of the up and down lines at the panel ends;
  5. A weak link with a maximum breaking strength of 1,100 lb (498.8 kg) must be placed at all buoys; and
  6. All anchored gillnets, regardless of the number of net panels, must be securely anchored with the holding power of at least a 22 lb (10.0 kg) Danforth-style anchor at each end of the net string.
