Right Whale Closures Still In Effect

Seasonal Trap and Gillnet Gear Closure to Protect Right Whales Will Remain in Effect
This advisory serves as notice that the Seasonal Trap and Gillnet Closures to Protect Right Whales remain
in effect until May 15 due to the continued presence of right whales in Massachusetts’ waters. DMF is
closely monitoring the presence of North Atlantic right whales and may lift these closures (and the small
vessel speed limit in Cape Cod Bay) prior to May 15 if observational data demonstrate right whales have
migrated out of our coastal waters. The commercial trap gear closure applies only to those state waters
north of Cape Cod to the New Hampshire border and east of Cape Cod east of 70°00’ west longitude (see
map), whereas the commercial gillnet closure and the recreational buoyed trap gear closure apply within
all waters under the jurisdiction of the Commonwealth. These closures are each designed to prevent
endangered right whales from becoming entangled in fixed gear and associated buoy lines. Given the
density of right whales in Massachusetts waters, DMF has also extended the seasonal speed restriction in
Cape Cod Bay until May 15 (see Notice).
The Division of Marine Fisheries, in conjunction with the Provincetown Center for Coastal Studies,
continues aerial surveillance of right whales north and east of Cape Cod. Most recently, on April 26, 2024
aerial surveillance of Cape Cod Bay detected 52 right whales, including 3 mother/calf pairs (Figure 1). In
addition, other right whale observations during the month of April have demonstrated aggregations of
right whales throughout the spatial extent of Massachusetts coastal waters and surrounding areas (Figure
2). This heavy use of Massachusetts waters in the month of April is very common. Additional
surveillance flights are anticipated to occur over the next several days to update our understanding of
whale distribution. DMF will reevaluate the status of this closure based on the presence or absence of
whales.
