“All of these captures help create the largest slaughter of dolphins on the planet,” says activist Ric O’Barry in the film, who is the campaign director for Earth Island Institute’s Save Japan Dolphins.

O’Barry, who is the protagonist of “The Cove,” was the original dolphin trainer for “Flipper,” the hit TV show. He has spent the past several decades as an activist working to free the world’s captive dolphins. “I feel somewhat responsible because it was the ‘Flipper’ TV series that created this multibillion-dollar industry,” he says. “It created this desire to swim with them and to kiss them and hold them and hug them and love them to death, and it created all these captures.” He adds: “I spent 10 years building that industry up, and I spent the last 35 trying to tear it down.”

It’s now illegal to import a dolphin caught in Taiji, or any similar drive around the world, into the United States. “NOAA [National Oceanic and Atmospheric Administration] does not and would not issue permits to import animals from the Japanese drive fisheries. It doesn’t meet the humane collection requirement of the Marine Mammal Protection Act,” explains Tom Eagle, a fishery biologist for the National Marine Fisheries Service, which is a part of NOAA.

But that wasn’t always the case. While the Marine Mammal Protection Act was passed in the early ’70s, as recently as the ’80s, marine theme parks, including SeaWorld, aquariums and even the U.S. Navy imported dolphins captured in Japan in slaughter drives.

“There was a time in our history when we took animals from this hunt, and of course we viewed it in a defensible way; they were the only animals that were going to survive,” says Jacobs of SeaWorld. “If you could ask these animals: ‘Who wants to volunteer to go to an aquarium?’ I think that you’d have quite a few animals that would volunteer.” (In this hypothetical human-marine mammal conversation, the reply might be: “If it’s all the same to you, I’d rather just go back to the ocean, thanks.”)

In 1993, environmentalists at Earth Island Institute threatened to sue the federal government if it allowed the importation of four live Pacific false killer whales (which despite the name are actually a type of dolphin) caught in a drive in Japan. NOAA did not issue the permits, and hasn’t allowed the importation of dolphins from such barbaric captures since.

Bottlenose dolphins, like the ones made famous in “Flipper,” haven’t been captured in U.S. waters since 1989. The last capture of any live dolphin in U.S. waters was in 1993 for the Shedd Aquarium in Chicago. It’s a point that Steve Feldman, a spokesperson for the Association of Zoos and Aquariums, wants to make clear. “We don’t have these animals. We wouldn’t take these animals,” he says, adding that AZA supports a petition denouncing the dolphin killings in Taiji, which has so far collected 124,000 signatures.

So, where do the jumping, splashing, performing dolphins in the U.S. come from today? They’re mostly bred in captivity. “Over 65 percent of bottlenose dolphins in our collections right now were born there,” says Menard. What about the other 35 percent? Dolphins can live to be 30 or 40 years old, so some of those in captivity were indeed once wild. The others are their descendants.

Among the 218 zoos and aquariums that are members of the AZA, there are about 200 dolphins living in captivity. More than 75 percent of those were born in captivity, according to Feldman.

Yet every year, wild dolphins captured in Taiji continue to be sold in Japan and internationally to the captivity industry. O’Barry estimates that about two dozen live dolphins are sold from Taiji every year, with buyers including aquariums and swim-with-dolphin operations in China, Dubai, Turkey, Mexico and the Philippines. In an e-mail statement, the Japan Embassy in the United States confirmed that from Taiji, “live animals go to domestic aquariums as well as foreign ones, but we don’t have a specific number.”

Yet even in countries where dolphins captured in this cruel manner are no longer being displayed, activists argue that the industry has an obligation to do a better job policing its own. Lending support to an online petition and officially denouncing the practice is not enough.

While the World Association of Zoos and Aquariums has joined groups like the AZA in officially denouncing the Taiji drive fishery, it has not expelled its members who continue to trade in the dolphins captured there.

“Members of the World Association of Zoos and Aquariums should be taken out of that membership organization until they end the use of these drive fisheries as a source of dolphins,” says Mark Berman, associate director of Earth Island Institute. He argues that the AZA should also publicly condemn American citizens operating in other countries, who trade in the dolphins captured this way.

And aquariums and marine parks, who profit from marine mammals, could be doing more to educate their visitors about the horrors taking place in Taiji. “They could at least tell their millions of visitors that this is going on,” says O’Barry. “How can it be really educational if you don’t give them the information?”

It’s O’Barry’s conviction that no dolphin can thrive in captivity, regardless of whether it was bred there, or caught in the wild in a drive. “You’re talking about a creature that’s primary sense is sonar,” he says. “You have a sonic creature in a concrete box. There are generations of dolphins born in a concrete tank who have never seen the ocean, have never seen a live fish, and have never experienced the tides or the current. They’ve lived in a concrete box. They were born there. These are freaks that we have inbred for our amusement.”

The dolphinariums disagree. “Based on objective science, dolphins in AZA-accredited facilities are healthy, long-lived and thriving,” writes the AZA’s Feldman in an e-mail. “Not only do these dolphins receive great care, they play an important role in science-based education programs that inspire millions to care more and do more for ocean conservation.”

Whether “The Cove” will shame Japan into ending the killing of dolphins in Taiji rests on whether the Japanese people get to see the film. The Tokyo International Film Festival recently decided not to screen the film, despite the fact that the theme of this year’s festival is ecology, and rolling out a “green carpet.”

O’Barry is asking Americans to boycott dolphin shows to protest the slaughter in Japan. And in September when the dolphin drive begins in Taiji, he will return to the cove to try to bring more attention to the bloodshed. This year, he says he’ll have actor Ben Stiller in tow.
