Catch shares slow the fisheries frenzy: Some confirmatory evidence

Environmental Economics

Economists regularly turn to one famous example when making the case for property rights in fisheries: Alaskan halibut. As soon as the season’s total allowable catch was reached – often just 24 hours after starting – the fishery was closed to preserve stock for the following year. Not surprisingly, given anecdotes like this, economists have long felt themselves on secure ground when advocating for catch shares in fisheries management.

Hyperstability: The Achilles’ Heel of Data-Poor Fisheries

Nature Conservancy - Science

There’s a basic logic to managing fisheries: as a fish population decreases you’ll catch fewer fish. Today the fishery is commercialized and fishermen use motorized boats and underwater flashlights.”. But that’s not the case in a hyperstable fishery.

Why we might need more catch shares in fisheries management

Environmental Economics

  NOAA Fisheries has determined 75 percent of the July-December quota of 431,460 pounds whole weight will be landed by August 28, 2016.    Reduction of the commercial vermilion snapper trip limit when 75 percent of the July-December quota is reached in federal waters of the South Atlantic complies with regulations implemented under the Fishery Management Plan for the Snapper-Grouper Fishery of the South Atlantic Region.

Quick Take: Technology Opens New Doors for Fisheries

Conservancy Talk

This week, I joined colleagues and partners at the Seaweb Seafood Summit in New Orleans, Louisiana to discuss sustainable seafood and fisheries. A consistent theme emerged: technology and innovation is opening new doors for small-scale fisheries. Small-scale fisheries account for a full 80 percent of the world’s fish catch, and play a critical role in the livelihoods of millions of people, particularly in the developing world.

My contribution to fisheries management

Environmental Economics

From the minutes of the November SSC Meeting in Charleston: DR. WHITEHEAD: I will add to that if separating quota by gear is a good idea and then separating quota by region has been suggested is a good idea, it is just a hop, skip and a jump to separating quota by fishermen to be a good idea; which would extend the season. DR. WHITEHEAD: Yes, the transferability of endorsements can only increase the economic efficiency of this amendment where economic efficiency can be measured by profits

Some empirical evidence on the benefits of catch shares in commercial fisheries

Environmental Economics

But over the last decade or so, a different kind of fisheries management program known as catch shares has been gaining ground. Researchers looked at monthly data from 39 federally managed commercial fisheries (worth a combined $402 million) such as Pacific halibut, Atlantic cod, New England haddock, Gulf of Mexico red snapper and more, which operate under catch share programs.

The 2006 reauthorization of Magnuson-Stevens provided a means to use new tools like the halibut program in federal fisheries management.

Red Snapper: Conflict and Opportunity in Managing a Recreational Fishery
