Entangled whale found off California coast just one of many, say experts

Rescuers resumed their efforts Saturday cutting off more fishing gear from an entangled humpback whale off the California coast, in a case that advocates say highlights a growing problem.

Calif. Rescuers will try again Saturday, Oct. 31, to remove more than 100 feet of fishing line from an entangled humpback whale that has been moving south along the Southern California coast.

A humpback whale off the coast of Los Angeles swam free Saturday after spending two days entangled in hundreds of feet of fishing line.

The entangled whale, thought to be between between 35 and 50 feet long, was spotted Friday 45 miles south of Los Angeles, along the Orange County coast. Rescuers from the National Oceanic and Atmospheric Administration (NOAA) were able to remove 150 feet of rope, but the whale soon became agitated and dove deeper, preventing further removal.

When rescuers resumed their efforts Saturday, a SeaWorld team cut over 230 feet of trap line off of the whale, leaving only some line in its mouth that they were unable to reach. But even though there may be little rope left, the line that remains could inhibit the whale's feeding. 

“We need to be realistic with regards to the ultimate outcome for this animal,” Dave Koontz, a SeaWorld spokesman, told NBC News. “While a significant amount of line was removed from the whale yesterday and today, there is still line in its mouth."

Experts say this case highlights a growing trend of whale entanglement.

In April 2015, The Center for Biological Diversity reported a record number of entanglements off the US Pacific coast last year. Of the 30 individual cases, a number twice that of the previous year, experts believe only seven of these whales survived.

Many more cases go undetected. As The Christian Science Monitor reported Saturday, “more than 300,000 whales, dolphins and porpoises die as bycatch every year, either from drowning or from the injuries sustained while struggling to escape.”

Several different causes could be behind the increase, say experts. EarthJustice reported in May that overfishing along the California coast has led to scarce supplies of food resources such as anchovies and sardines, causing whales to search for food closer inland. Harbor Patrol St. Steve Marble told the Los Angeles Times that unusually warm ocean temperatures have brought more whales to the coast of Southern California.

“Our response network is really just a Band-Aid,” Justin Viezbicke, and NOAA program specialist who helped with Saturday’s rescue, told the Associated Press. “We’re looking for ways to be proactive and minimize these situations in the future.”

Other long-term efforts to reduce whale entanglement include trap limits and industry retrieval of lost crab pots. But The Center for Biological Diversity, EarthJustice, and Oceana say more needs to be done, and they recently asked the California Department of Fish and Wildlife to consider other measures such as breakaway lines, fishery closures in whale feeding areas, and restrictions on the number of vertical fishing lines in the water.

“There are simple, common-sense solutions that will protect the whales, and we’re calling on the state to manage this fishery to protect whales,” said Catherine Kilduff, an attorney with The Center for Biological Diversity, said in a press release. “We want to see meaningful changes to address this growing problem before the next crab season begins.”

What is the Monitor difference? Tackling the tough headlines – with humanity. Listening to sources – with respect. Seeing the story that others are missing by reporting what so often gets overlooked: the values that connect us. That’s Monitor reporting – news that changes how you see the world.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
