While some of the steps the ancient Hawaiians took to protect their catch are extreme by today’s standards, conservation experts would find many of them familiar.

When the first Europeans settled on the remote Pacific island chain of Hawaii in the 18th century, fishing had been going strong for centuries. 

Each local ruler made sure it stayed that way.

“If [the ruler's agent] decided¹ that the fish stock on a particular reef needed to rest - people had been fishing it too much - then he would put a kapu on that reef,” says geographer² Jack³ Kittinger of Stanford University's Center for Ocean Solutions.

“Kapu” roughly translates as “forbidden,” and that was enough for the local fishers, Kittinger says.

Capt. James Cook, the first European to reach Hawaii, saw the kapu system in action. 

Cook would see Hawaiian fishermen out on the water one day.

"The next day there was a kapu put on the bay by the local king, and no one was on the water," Kittinger says. "People obeyed these things.”

It was also kapu to catch skipjack tuna for roughly half the year, and mackerel scad the other half. 

Also, only a professional class of fishermen was allowed to fish in deeper waters and use certain types of equipment.

Those and other traditional methods kept the coral reef ecosystems⁴ producing as much or more fish as they are today. And they had done so for about 400 years before Europeans arrived, according to a study by Kittinger and his co-author published in Fish and Fisheries. 

Today, on the other hand, overfishing threatens the Hawaiian reefs, and more than half of the reefs around the world.

When Kittinger looks at today’s efforts to control overfishing, he sees a lot of parallels with the ancient Hawaiian practices. 

“They had basically the same tools in the toolbox that we have today," he says. "We do the same thing. We say, ‘You can use this gear here, but you can’t use it there. This area is off limits,’ and so on and so forth⁵. But the difference is how those strategies are implemented⁶.”

The difference, he says, is if you broke a kapu, “You’re in deep trouble,” he says. It could mean blinding or even death. 

Some other strategies are out of step with modern values. Women were forbidden from eating certain kinds of prized fish. Turtles were off-limits for everyone but chiefs and high priests. 

These rules had the effect of protecting these species. 

“We think that the fact that they were protected probably arose as a response to understanding that those species were vulnerable,” Kittinger says.

Living on remote islands in the middle of the ocean, subject to storms, droughts, tsunamis⁷ and so on, Kittinger says protecting the food supply was a matter of life and death for the ancient Hawaiians.

But with ocean ecosystems worldwide in decline, Kittinger says we could learn from their experience.

“These days, you get a slap on the wrist if you break a fisheries law," he says. "And it just tells us we don’t really take enforcement that seriously. If we were really serious about protecting the resource, we need to be more serious about the violations⁸ and what happens with the violator.”

He is not suggesting bringing back the death penalty for violators, but says today’s more relaxed attitudes are not enough.
