Approved Weak Rope for Atlantic Large Whale Take Reduction Plan

Requirements for the use of buoy line with a maximum breaking strength of 1,700 lbs through the use of manufactured weak rope (below) or weak inserts are outlined in the 2021 modifications to the Atlantic Large Whale Take Reduction Plan. These requirements apply to the Northeast Lobster/Jonah crab trap/pot fishery only. Requirements for all other areas, other trap/pot fisheries, and gillnet fisheries remain the same. 

The modifications remove the requirement for weak link at buoys and other surface system flotation devices, though they are not prohibited, and adds requirements for weak rope or insertions within the buoy line. 

Fishermen are also encouraged to maintain their buoy lines to be as knot-free as possible, using the least number of knots necessary given the length of the buoy line. Splices are considered to be less of an entanglement threat and are preferable to knots.

Average breaking strengths were determined through 10 consecutive tests on a calibrated rope-breaking machine at the NEFSC lab in 2021. To be approved, the average breaking strength must be within 10 percent of 1,700 lbs. These tests are the basis for NOAA Fisheries approval of this rope. 

Approved Fully Formed Weak Rope - Braided Ropes

The approved braided ropes can be used as full weak rope (but not inserts) connected to your regular line using a knot at the depth required for your fishing area (the depth of your lowest required weak insertion or the proportion of your rope required to be weak).

Currently the fully formed weak ropes approved for use are:
