DEEP: Notice to Lobster Pot Fishermen


March 29, 2010

Subject: Long Island Sound Trawl Survey - Spring and Fall 2010

Enclosed are maps showing the locations of CT DEP monthly trawl survey sites to be sampled during 2010 from the research vessel R/V John Dempsey. Lines on the map give the direction and distance of each tow. For the exact start and end of each tow, please refer to the tables using the reference number for each tow printed on the map. The tables have the reference number, LORAN TD and Lat/Lon coordinates at the start and end of each tow, trawl survey site number and description of the tow (for example: East-West Tow).  Although the U.S. Coast Guard has ceased broadcasting Loran TDs as of February 2010, we will continue to provide the historical TDs for each tow for the convenience of those more familiar with that coordinate system. However, TDs are approximate and should be used as a rough guide only. Tows are now conducted using the Latitude and Longitude coordinates.

The packet includes site maps and tables for the spring and fall 2010 Long Island Sound Trawl Survey. In the past, we sent monthly reminders, however, we have reduced our mailings to two times per year; once in the spring and once in the fall. This will be your only notice for the April, May and June surveys. Check the maps for each month to see the dates the trawl survey is scheduled to occur. For the September and October months we will send a reminder a couple weeks prior to the beginning of the September survey.

This notice, along with the accompanying maps and tables, are posted on the DEP website (go to and click on COMMERCIAL in the left column, then click the link for Monthly Trawl Survey Maps).

We are providing this information in order to avoid accidental disturbance of your gear and to maintain the integrity of our survey so that we can continue to provide the best possible monitoring of the Soundís fishery resources. For this effort to be successful we need your cooperation by removing any gear you have within one-half micro second to either side of the survey line for the duration of each monthís survey.  Provided gear is set in an orderly fashion, this space -- about 500 ft -- is an adequate width for towing the relatively small net used in the survey.

Your cooperation in providing a clear path for sampling is greatly appreciated, This survey continues to provide needed information for assessments of Long Island Sound fish and lobster resources.

Each month, the survey is expected to begin in the east and progress westward. It generally takes 10-12 days of good weather (each month) to complete the survey. You can reach the R/V John Dempsey at 860-490-3275 or on VHF CH 16 & 13 anytime the vessel is on the water. The crew can tell you at any time during the survey period what sites have been done and approximately when sites in a given area will be sampled. We hope this communication can minimize the amount of time your gear will have to be moved.

Again, we appreciate your cooperation. Please contact David Simpson at the Marine Fisheries office in Old Lyme, CT if you have questions on the survey or the schedule for sampling in your area.
