Quirky livestream that lets viewers help fish is a hit with millions

  • When viewers see enough fish, they alert a water worker who opens the lock to let the fish swim through
  • Letting the fish through help them make their springtime migration to shallow spawning grounds

UTRECHT, Netherlands: The central Dutch city of Utrecht has installed a ” fish doorbell ” on a river lock that lets viewers of an online livestream alert authorities to fish being held up as they make their springtime migration to shallow spawning grounds.
The idea is simple: An underwater camera at Utrecht’s Weerdsluis lock sends live footage to a website. When somebody watching the site sees a fish, they can click a button that sends a screenshot to organizers. When they see enough fish, they alert a water worker who opens the lock to let the fish swim through.
Now in its fifth year, the site has attracted millions of viewers from around the world with its quirky mix of slow TV and ecological activism.

Much of the time, the screen is just a murky green with occasional bubbles, but sometimes a fish swims past. As the water warms up, more fish show up.

Without the help, native freshwater fish like bream, pike and bass can become backed up behind the lock and form easy prey for predators in the spring, when the lock is rarely opened for passing boats.
The bell is the brainchild of ecologist and concept developer Mark van Heukelum. He’s been happily surprised at the response, with millions of people from around the world tuning in over the years.

“I guess the combination of a good cause, a beautiful story and just a simple idea generates all this attention,” he said.
Anna Nijs, an ecologist with Utrecht municipality, was also amazed at the popularity of the concept around the world.
“We get a lot of fan mail from people who think it’s slow TV and they find it relaxing,” said Nijs. Besides, “they appreciate that they can actually do something to help.”

Some Warren Buffett wisdom on his last day leading Berkshire Hathaway

OMAHA, Nebraska: The advice that legendary investor Warren Buffett offered on investing and life over the years helped earn him legions of followers who eagerly read his annual letters and filled an arena in Omaha every year to listen to him at Berkshire Hathaway’s annual meetings.
Buffett’s last day as CEO is Wednesday after six decades of building up the Berkshire conglomerate. He’ll remain chairman, but Greg Abel will take over leadership.
Here’s a collection of some of Buffett’s most famous quotes from over the years:
___
“Be fearful when others are greedy, and greedy when others are fearful.”
That’s how Buffett summed up his investing approach of buying out-of-favor stocks and companies when they were selling for less than he estimated they were worth.
He also urged investors to stick with industries they understand that fall within their “circle of competence” and offered this classic maxim: “Rule No. 1: Never lose money. Rule No. 2: Never forget Rule No. 1.”
___
“After they first obey all rules, I then want employees to ask themselves whether they are willing to have any contemplated act appear the next day on the front page of their local paper to be read by their spouses, children and friends with the reporting done by an informed and critical reporter.
“If they follow this test, they need not fear my other message to them: Lose money for the firm and I will be understanding; lose a shred of reputation for the firm and I will be ruthless.”
That’s the ethical standard Buffett explained to a Congressional committee in 1991 that he would apply as he cleaned up the Wall Street investment firm Salomon Brothers. He has reiterated the newspaper test many times since over the years.
___
“You only find out who is swimming naked when the tide goes out.”
Many companies might do well when times are good and the economy is growing, but Buffett told investors that a crisis always reveals whether businesses are making sound decisions.
___
“Who you associate with is just enormously important. Don’t expect that you’ll make every decision right on that. But you are going to have your life progress in the general direction of the people you work with, that you admire, that become your friends.”
Buffett always told young people that they should try to hang out with people who they feel are better than them because that will help improve their lives. He said that’s especially true when choosing a spouse, which might be the most important decision in life.
___
“Our unwavering conclusion: never bet against America.”
Buffett has always remained steadfast in his belief in the American capitalist system. He wrote in 2021 that “there has been no incubator for unleashing human potential like America. Despite some severe interruptions, our country’s economic progress has been breathtaking.”
