Scientists from NOAA Fisheries Service and its state and nonprofit partners successfully used at-sea chemical sedation to help cut the remaining ropes from a young North Atlantic right whale on Jan. 15 off the coast of Cape Canaveral, Fla. The sedative given to the whale allowed the disentanglement team to safely approach the animal and remove 50 feet of rope which was wrapped through its mouth and around its flippers.
This is only the second time a free-swimming whale has been successfully sedated to enable disentanglement efforts. The first time a whale was successfully sedated and disentangled was in March 2009 off the coast of Florida.
“Our recent progress with chemical sedation is important because it’s less stressful for the animal and minimizes the amount of time spent working on these animals while maximizing the effectiveness of disentanglement operations,” said Jamison Smith, Atlantic Large Whale Disentanglement Coordinator for NOAA’s Fisheries Service. “This disentanglement was especially complex, but proved successful due to the detailed planning and collective expertise of the many response partners involved.”
The young female whale, born during the 2008-2009 calving season and estimated to be approximately 30 feet long, was originally observed entangled on Christmas Day by an aerial survey team. On Dec. 30, a disentanglement team of trained responders from the Georgia Department of Natural Resources and Florida Fish and Wildlife Conservation Commission were able to remove 150 feet of rope from the whale, but additional rope remained. NOAA and its partners continued to track the animal via satellite tag to determine if it would shed the remaining gear on its own. Calm weather conditions were necessary before attempting further intervention on Jan. 15.
During this response, scientists used for the first time a special digital monitoring tag that recorded the whale’s behavior before, during and after sedation. Sedating large whales at sea is in its infancy and data collected from the digital archival tag will be used to inform future sedation attempts that may be necessary. After disentangling the whale, scientists administered a dose of antibiotics to treat entanglement wounds and a drug to reverse the sedation. The whale will be tracked up to 30-days via a temporary satellite tag.
The disentanglement and veterinarian team consisted of scientists from: NOAA Fisheries Service, Georgia Department of Natural Resources, Florida Fish and Wildlife Conservation Commission, Woods Hole Oceanographic Institution, University of Florida, EcoHealth Alliance, and Coastwise Consulting. The Provincetown Center for Coastal Studies and the New England Aquarium also provided offsite support.
Fishing gear removed from this whale included ropes and wire mesh material, similar to what is found in the trap or pot fisheries for fish, crab and lobster along the mid-Atlantic, northeast U.S., and Canadian coasts. However, the specific fishery and its geographic origin are pending examination by experts at NOAA’s Fisheries Service.
With only 300-400 in existence, North Atlantic right whales are among the most endangered whales in the world. They are protected under the U.S. Endangered Species Act of 1973 and the Marine Mammal Protection Act of 1972. Vessel strikes and entanglement in fixed fishing gear are the two greatest threats to their recovery.
NOAA Fisheries Service encourages people to report sightings of dead, injured, or entangled whales to the Florida Fish and Wildlife Conservation Commission at 1-888-404-FWCC (3922) or the Georgia Department of Natural Resources at 1-800-2-SAVE-ME (272-8366). All live right whale sightings should be reported to the USCG via Channel 16.
NOAA’s mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources. Visit us at http://www.noaa.gov  or on Facebook at http://www.facebook.com/usnoaagov. 
Georgians can help conserve North Atlantic right whales and other nongame wildlife, native plants and natural habitats through buying a wildlife license plate featuring a bald eagle or a ruby-throated hummingbird. They can also donate to the Georgia Wildlife Conservation Fund through the state income tax checkoff and other ways. Contributions are vital to the Georgia DNR’s Nongame Conservation Section, which receives no state general funds for its mission to help conserve wildlife not legally hunted, fished for or trapped, as well as rare plants and natural habitats.
