Cowichan Bay sea lion rescued from life-threatening entanglement<\/p>\n

A Steller sea lion is breathing a little easier now following the successfull removal of a severe neck entanglement, authorities say.<\/p>\n
The female sea lion, later named Stl\u2019eluqum by members of the Cowichan Tribes, was first spotted in Cowichan Bay on Nov. 7. The Vancouver Aquarium Marine Mammal Rescue Society (VAMMR) was notified shortly thereafter.<\/p>\n
VAMMR and Fisheries and Oceans Canada (DFO) engaged in a \u201ccomplex, weeks-long rescue effort,\u201d that was \u201csupported by the Cowichan Tribes, coastal observers, and a highly engaged online community,\u201d according to the Vancouver Aquarium.<\/p>\n
But weather challenges, limited daylight and the animal\u2019s infrequent movement patterns hampered many attempts to help.<\/p>\n<\/p>\n
Meanwhile, a thick polypropylene rope wrapped around her neck was causing rapidly worsening injuries, making the rescue increasingly urgent.<\/p>\n
On Dec. 9, VAMMR and the DFO spent all day searching for the animal but it was a fortuitous spotting by a Cowichan Tribes member late in the day that enabled rescuers to help it.<\/p>\n
\u201cThe team safely sedated the sea lion and, once they began removing the rope, discovered it had been wrapped around her neck four times. After the debris was removed, the sedative was reversed and the animal swam away,\u201d said a Vancouver Aquarium press release.<\/p>\n
The organization said \u201cover the past two decades, the Vancouver Aquarium Marine Mammal Rescue Society has played a leading role in developing a specialized technique to safely disentangle sea lions. The method uses a dart-delivered immobilization drug combination that allows trained responders to safely approach the animal and remove the debris.\u201d<\/p>\n
VAMMR\u2019s executive director and head veternarian Dr. Martin Haulena is the only veterinarian in Canada \u2014 and one of only a few worldwide \u2014 qualified to perform the procedure.<\/p>\n
\u201cThese are large, wild animals, and the risks involved in disentanglement trips can be significant for both the responders and the sea lion,\u201d Haulena said. \u201cMost of these cases are caused by marine debris and, if nothing is done, the outcome is usually fatal. In this case the rope was cutting deeper by the day and removing it was critical to this animal\u2019s survival.\u201d<\/p>\n
Haulena reminds the public that this time of the year in particular, can lead to increased waste and more marine debris.<\/p>\n
\u201cEntanglement in ropes, plastics, and other discarded materials continues to be a major threat to marine mammals along the B.C. coast, and preventing debris from entering the ocean is essential to reducing these incidents.\u201d<\/p>\n
