| MarineFisheries UPDATED ADVISORY TO MARINERS May 7, 2007 AGGREGATION OF RIGHT WHALES FROM LONG POINT TO HIGHLAND LIGHT Updated Advisory to Mariners An aggregation of right whales off Provincetown has prompted the Division of Marine Fisheries (MarineFisheries) to re-issue an advisory to all vessel operators. Operators are advised to reduce speed (10 knots), post lookouts, and proceed with caution to avoid colliding with this highly endangered whale. On April 25, MarineFisheries issued an initial advisory for this area. The DMF/CCS aerial survey team reported an aggregation of 20 right whales surface feeding around the tip of Cape Cod. Survey efforts conducted on May 5 established that right whales are still present and feeding in this area. Whales that are surface feeding on dense blooms of plankton (copepods) are at great risk for vessel strike. We will re-evaluate the level of risk after analyzing whether the plankton resources in this region remains high enough to support right whale feeding, aggregation, and residency. When right whales depart the area, the advisory will be lifted. Vessels are prohibited by state and federal law from approaching within 500 yards of a right whale. Massachusetts Environmental Police and U.S. Coast Guard are authorized to enforce the 500-yard rule. Fishermen are reminded that the approach rule also prohibits them from starting fishing operations (setting or hauling gear) within 500 yards of a right whale. Right whales are the most endangered large whale in the North Atlantic, with a population of approximately 350 animals. Ship strikes are a major cause of human-induced mortality for right whales and more vessel traffic is expected in this area over the next few weeks with seasonal increases in recreational and commercial fishing, as well as whale watching, and passenger ship activity. On March 12, 2007, the CCS aerial surveillance team spotted a juvenile right whale off Provincetown with deep propeller wounds. It is unknown where this vessel interaction took place, but based on the condition of the wound, the injury likely occurred only weeks prior to the sighting. This sighting highlights the risk posed to right whales by vessel traffic. Management of maritime activities near right whales is part of the MarineFisheries Right Whale Conservation Program. The Right Whale Conservation Program is a cooperative effort between MarineFisheries and the Provincetown Center for Coastal Studies (CCS) to study and protect right whales in Cape Cod Bay. Real-time monitoring of right whales through vessel and aerialbased surveillance, and forecasting of right whale presence through habitat analysis, makes the Massachusetts Right Whale Conservation Program the most comprehensive of any program throughout the species range. The presence of whales is also being monitored by MarineFisheries and Cornell University researchers through real-time acoustic listening stations. Since 2003, MarineFisheries has collaborated with Cornell University and Woods Hole Oceanographic Institute (WHOI) to build the worlds first real-time acoustic monitoring system for right whales in Cape Cod Bay. Right whale call are detected by the buoys and communicated back to Cornell and shared with researchers, vessel operators, and fishery managers. Support for the Conservation Program is granted from NOAA Fisheries and the National Fish & Wildlife Foundation. The National Marine Fisheries Service (NOAA Fisheries) issues warnings to mariners via the Northern Right Whale Sighting Advisory System (SAS). Participating agencies in the SAS include MarineFisheries and the Massachusetts Environmental Police, the U.S. Coast Guard, the U.S. Army Corps of Engineers (ACOE), CCS, and other research groups.
