A significant proportion of catch by artisanal fishers in Ghana is sold through wealthy middle-women, known as “fish mothers,” who often pre-finance fishing trips. This study examined the determinants of catch sales through fish mothers. Data used came from artisanal fishermen at major coastal fishing communities in Ghana. The effects...
As fisheries management becomes more collaborative by seeking input and involvement from stakeholders, it is important to understand and address the diversity of those stakeholders. Gulf Coast fisheries communities include diverse racial and ethnic groups, particularly a large number of Vietnamese Americans involved in all aspects of the seafood industry....
This paper is the result of a project that began with NAAFE 2015 special session on Fisheries Certification, which asked what forces are driving the market for sustainable seafood. Many previous studies looked at consumers' demand, but in this paper we looked at the entire supply chain (from producers to...
National Standard 1 states that a primary function of fisheries management in the single stock case is the determination of the annual allowable harvest, and it is based on the selection of a target stock size and a control rule that will specify a harvest path that that will cause...
In many small-scale fisheries around the world, hookah diving is the main fishing method and gear to catch high-value species like sea urchin, sea cucumber, queen conch and spiny lobster. Decompression sickness (DCS) and carbon monoxide poisoning (COP) are diseases related to hookah diving and are the cause of non-fatal and...
Choosing a policy instrument is a strategic choice. In the case of fisheries interactions with marine mammals and sea turtles, the preferred policy instrument has been a command-and-control approach such as effort reductions (e.g. area closures) and/or technology standards (e.g. gear modifications), even though market based approaches are available. Since...
Parasites and diseases represent major challenges in aquaculture. In the Norwegian salmon farming industry, costs associated with treatment of sea lice are surging and reached 5bn NOK or 10% of the industry’s total export value in 2015. In addition to the direct impact on production, sea lice affect the industry...
The Pacific sardine fishery is shared but independently managed by three nations: Canada, USA and Mexico. As a result, potential conflict scenarios may arise. A stochastic optimal control methodology is presented to analyze potential conflict scenarios by first considering a deterministic logistic stock growth function and adding a stochastic term,...
The potential economic impact of a fully developed mariculture industry in Alaska is not well understood by industry or policy makers. It is also not entirely clear what is needed to move from Alaska’s current micro industry (approximately $500,000 in annual sales) to a fully developed industry. In general, the...
Alaska is the world’s principal supplier of Sablefish Anoplopoma fimbria a buttery-flavored whitefish greatly prized in Japan. Sablefish are distributed from Baja California to western Japan but the majority of commercial catches are from the Gulf of Alaska and the Aleutian Islands off Alaska. Landings volume and value of this...
This presentation provides an overview of a Special Session presentation held at the NAAFE Forum 2017 in March, 2017. The title of the special session was: Saving the World's Most Endangered Marine Mammal. The session was organized by Oriana Poindexter.

Sablefish (Anoplopoma fimbria) are distributed from Japan to Baja California. Alaska is the world’s principal supplier of sablefish with the majority of commercial landings occurring in the Gulf of Alaska and the Aleutian Islands. This demersal, long-lived fish is in one of Alaska’s highest value commercial fisheries. In terms of...
The paper puts forward a model of the Pearl River Delta (PRD) fishery in the South China Sea that integrates the ecological, social and economic costs and benefits of fisheries activities in a multidisciplinary framework. In particular, In particular, we developed integrated model by linking a regional Social Accounting Matrix...
Bering Sea/Aleutian Islands (BSAI) groundfish fisheries are hugely productive with 2008 – 2014 harvests averaging 1.6 million tons and generating $1.95 billion annually. The BSAI also hosts a commercial halibut fishery with 2013 landings of 3,500 tons and revenues of $41.5 million. Downward trends in halibut biomass combined with continued...
Purchases made by marine recreational anglers are an important source of economic activity in coastal areas around the United States. In recognition of the economic contributions anglers make to coastal state economies, NOAA Fisheries conducts surveys every three to five years in order to gather data on expenditures made by...
The Gulf of California is undoubtedly the Mexican marine region with the most research and conservation efforts. In addition to overfishing issues, it harbors endemic and Critically Endangered populations of totoaba (Totoaba macdonaldi) and vaquita (Phocoena sinus). Conservation strategies have varied, but there is a wide recognition of their historic...
This research combines a utility-theory consistent model of demand for recreational fishing trips with an age-structured stock dynamics model to provide policy relevant advice to managers of the groundfish fishery in the Northeast United States. We provide an overview of the model and describe the challenges encountered with using this...
Ecosystem services (ES) represent a way to represent and quantify multiple uses, values as well as connectivity between ecosystem processes and human well-being. Ecosystem-based fisheries management approaches may seek to quantify expected trade-offs in ecosystem services due to actions such as restoration and gear restrictions, or due to changes such...
