LOS ANGELES, CA — The hunt is on for the great blue whale in distress.

A plane, helicopter and boat searched Saturday for a blue whale entangled in fishing line off southern California after rescue efforts were suspended overnight, an official said.

The blue whale was tethered to a red-orange buoy Friday that should allow rescuers and seafaring public to more easily spot it, said Peter Wallerstein, president of Marine Animal Rescue, a nonprofit authorized to rescue marine animals.

“It’s really big,” Wallerstein said of the animal.

The entangled whale is 80 feet long, he said. The longest blue whale ever measured was more than 108 feet long, the Smithsonian Institute says.

The blue whale, an endangered species that’s also Earth’s largest animal, was last seen Friday four miles off the southern end of Catalina, an island 22 miles off mainland California, Wallerstein said.

“They can move pretty quick,” Wallerstein said of the blue whale’s whereabouts. “They travel long distances in a short period of time.”

Aerial photos Friday showed the whale surfacing and then diving, pulling a long fishing line.

“It’s in pretty good condition,” Wallerstein said Saturday. “It looks a little thin. It’s swimming really good. We put a buoy on it last night that should slow it down, and we should be able to spot it.”

The mission of federal, local and nonprofit teams is to free the blue whale from the fishing net. Whale watchers first reported the whale trapped in the netting.

The National Marine Fisheries Service has made a national priority out of addressing the injury and mortality of large whales entangled in fishing gear such as traps, pots and netting.

An average of 11 large whales have become entangled in such gear on the West Coast from 2000 to 2012, the National Oceanic and Atmospheric Administration says.

“However, along the U.S. west coast, much is unknown about why, when, where, and how whales are seriously injured or killed due to entanglement, how this threat may be affecting their populations, and what can be done to minimize the risk,” said a 2013 report by NOAA’s National Marine Fisheries Service.

There are 10,000 to 25,000 blue whales in the world, according to the World Wildlife Fund. They can be found off California, Chile and the Coral Triangle near Indonesia.
