Boaters warned of entangled blue whale
MARINE mammal rescue teams alerted boaters off Southern California on Tuesday to be on the lookout for a blue whale ensnared in the rigging of a commercial crab trap, a day after initial efforts to free the giant creature failed.
Rescuers spent an entire day trying to cut free the 24-meter-long whale on Monday, ending the operation around nightfall, and hoped for a second chance at disentangling the distressed animal, authorities said.
As of late Tuesday, the whale and a tell-tale string of yellow-and-orange buoys trailing behind it remained out of sight, said Gisele Anderson, whose husband, Dave, runs a fleet of whale-watching excursion vessels involved in the effort.
The whale was spotted about 48km off San Diego near Dana Point by the crew of Captain Dave’s Dolphin and Whale Watching Safari, Anderson said.
Blue whales, an endangered species, grow up to 30 meters in length and weigh close to 200 tons, ranking as the largest living animals on Earth.
Whale entanglements are not uncommon, and can prove lethal, according to Michael Milstein, a spokesman for the National Oceanic and Atmospheric Administration (NOAA). “The animal has to work that much harder pulling that gear around for it to survive,” Milstein said.
“It’s going to be a long-term debilitating problem for the whale if it doesn’t get free.”
Last year, 61 whales were found caught in fishing gear, crab pots and netting and nearly 40 have been reported so far this year along the US West Coast, Milstein said.
Most are gray and humpback whales, which tend to swim closer to shore, while blue whales are more common in the open ocean, according to Milstein.
He said the blue whale encountered near Dana Point was only the second one ever reported ensnared off the West Coast, and the first rescuers have tried to free.
Two buoys attached to the entanglement identified it as part of a crab trap from Morro Bay, off central California, Anderson said.
The harness was stuck in the whale’s mouth and was dragging the heavy main rigging of the trap beneath the animal, encumbering its ability to swim and feed, she said.
