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.

The Surprising Importance of Freshwater Fisheries to Global Food Security

Nature Conservancy - Science

If you’re thinking about how fisheries feed people around the globe, chances are you start picturing oceans. But what about freshwater fisheries? The reality, though, is that freshwater fisheries are crucial in feeding millions of people around the globe. A recently published study in the Proceedings of the National Academy of Sciences links freshwater fisheries management to both food security and biodiversity conservation.

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

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. 

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. New research from the Solomon Islands indicates that hyperstability — when catch rates remain high even as fish are rapidly depleted — could be a major challenge for assessing data-poor coral reef fisheries. Today the fishery is commercialized and fishermen use motorized boats and underwater flashlights.”. But that’s not the case in a hyperstable fishery.

Can Big Data Save the World’s Fisheries?

Nature Conservancy - Science

Big Data – it’s the latest silver bullet that can spot business trends, prevent disease, combat crime, and even revolutionize the health of fisheries. IUU threatens sustainable fisheries worldwide, with devastating environmental and socioeconomic consequences. It accounts for 20 percent of global fish catch, contributing to economic losses of $10 to 23 billion annually and threatening the livelihoods of millions who rely on healthy fisheries.

Marty is an economist in the Nicholas School of the Environment at Duke University and one of the signers of a petition , along with myself, to Congress supporting policy that generates economic efficiency: Economists have long understood that the cause of fisheries problems is the inability to exclude users. The 2006 reauthorization of Magnuson-Stevens provided a means to use new tools like the halibut program in federal fisheries management.

The Path to Sustainable Fisheries is Paved with Data

Nature Conservancy - Science

In fact, of the more than 10,000 fisheries in the world, fewer than 440 (mostly in upper-income countries and in top-traded fish like tuna) are regularly assessed — measured — with robust scientific methods. That means the vast majority of the world’s fisheries go unmeasured and therefore unmanaged. The bad news is: Unmanaged fisheries are at high risk of over-fishing and collapse, damaging economies, human health and biodiversity. Can Big Data Save the World’s Fisheries?

Red Snapper: Conflict and Opportunity in Managing a Recreational Fishery

Nature Conservancy - Science

Managing fisheries is extremely complex and difficult , because people love to catch and eat fish. One such conflict is brewing in the Gulf of Mexico right now – how to manage the recreational red snapper fishery. The National Marine Fishery Service (NMFS) says that states are going rogue and setting non-compliant season dates inside state waters, messing up its ability to properly estimate season lengths to avoid annual overharvests.

Quick Study: A California-Style Approach to Sustainable Fisheries

Nature Conservancy - Science

Many fisheries around the world are fished at unsustainable levels, but fishermen don’t not have the ability or incentive to change practices for the longer-term benefit. In fisheries where there are some economic and regulatory incentives already in place for fishermen to collaborate on conservation goals, the authors say, an investment-based approach similar to the one used on California’s Central Coast could help reform practices and lead to a more sustainable fishery.

Furthermore, many larvae settled just a few kilometers from their parents and ended up on reefs owned by the same community that protected the aggregation, providing direct fisheries benefits.

In a study presented at the 2013 Student Conference on Conservation Science in Brisbane, Australia, I set out to understand the fishing behavior of a highly mobile, well-financed offshore fishery, using the western Indian Ocean tropical tuna purse seine fleet as a case study example. This sort of uncertainty is highly undesirable in fishery management. Purse seine fishing.
