Study: Cooperative Fisheries Make Cash

December 7, 2007

GRANTS PASS, Ore. — At a time when a quarter of the world’s fisheries are considered depleted, can commercial fishermen make more money by fishing less?

A study published in the Friday edition of the journal Science says they can – with one condition.

They must be in a cooperative fishery, like those operating in New Zealand and Australia, where individual fishermen own a share of the total harvest rather than the competitive fisheries more common in the United States, where it’s a race to catch the most fish.

The idea is that when there are more fish and no race to catch them, fishermen spend less on fuel and other costs chasing far and wide to fill their nets, and can concentrate on delivering a high-quality product to the dock, said lead author Quentin Grafton, research director at the Crawford School of Economics and Government at Australian National University.

Leaving more fish in the sea – a fishery management target called maximum economic yield – leads to higher profits than the traditional target known as maximum sustainable yield, the study said.

“We like to say it’s a win-win,” said co-author Ray Hilborn, professor of fishery sciences at the University of Washington. “You have fishermen making more money. You have ecosystems that are healthier. And you have more fish in the ocean.”

The Food and Agriculture Organization of the United Nations has classified 25 percent of the world’s fish stocks as depleted, meaning populations are below a level that produces a maximum sustained yield.

The situation is similar in the U.S., where NOAA Fisheries has assessed 41 of 181 fisheries – 23 percent – as overfished, including the once-thriving New England cod fishery and some West Coast groundfish. Fishermen competed at both fisheries, but saw drastic harvest reductions and economic pain when fish numbers plummeted.

Only a handful of U.S. fisheries are managed so that fishermen own a share of the overall harvest, said Hilborn. Among them are Pacific halibut, Alaskan crab, and East Coast clams.

Since the West Coast groundfish fleet was cut in half by an industry-funded buyback, depleted fisheries are rebuilding, and federal fisheries managers are considering the fleet’s proposal to adopt harvest quotas for more stocks, but the process takes years, said Pete Leipzig, director of the Fishermen’s Marketing Association.

The study looked at big eye tuna and yellow fin tuna fisheries off New Zealand, and northern tiger prawn and orange roughy fisheries off Australia, all of which give fishermen individual shares of the overall harvest.

The authors plotted revenue and profit against models for fish abundance. Maximum revenues generally came at lower fish populations, but maximum profits came at higher fish populations, and the more overfished the fishery, the greater the profit gains from rebuilding. Profits turned to losses long before the last fish was caught.

To overcome opposition from fishermen, loans could be taken out to pay them for not fishing as the stocks rebuild. The loans would be repaid by the fishermen when the fish were abundant, said Grafton.

“We’ve always known that was good for conservation, and now they are showing it’s good for your bottom line,” Kate Wing, a senior ocean policy analyst for the Natural Resources Defense Council, a conservation group, said of the study’s findings.

Colin Clark, professor emeritus of mathematics at the University of British Columbia and author of the book, “The Worldwide Crisis in Fisheries,” said he has seen similar results to the study’s findings among Canadian fisheries managed with quotas.

He said a lot of countries are moving toward such systems. “The bad news is there are really problems in deep sea fisheries that take place outside anybody’s coastal waters. It’s like the Wild West with no law whatever.”
