Reference Points for Vulnerable Fish Species Based on Bioeconomic Age-Structured Models: An Approach for Totoaba macdonaldi

Creator:: Rodríguez-García, Oswaldo Uriel, De Anda-Montañez, Juan Antonio, Valenzuela-Quiñonez, Fausto, Hernández-Flores, Alvaro, Salas-Márquez, Silvia, and María Da-Rocha, José
Abstract:: Management objectives of vulnerable fish species must focus on maintaining healthy population status. Hence, reference points should be constrained to ensure recruitment. We assessed bioeconomic reference points for the totoaba (Totoaba macdonaldi), an endemic fish to the Gulf of California, reaching lengths of 2 m and 25 years. Totoaba fishing...

FIPs: Their Growth and Performance 2006 to 2016

Creator:: Cannon, James, Sousa, Pedro, and Veiga, Pedro
Abstract:: Retailers and suppliers of seafood are concerned about assured supply and their broader reputation with consumers. In theory, these concerns align with efforts to manage fisheries sustainably and reduce their environmental and social impacts. Hence engaging seafood supply chains more actively in fisheries management should help improve the fisheries in...

Quantity vs Quality: Freshness and Fishing Trip Length

Creator:: Abe, Keita and Ishimura, Gakushi
Abstract:: We suggest freshness as a critical factor in determining fishing trip duration. Using daily logbook data from a Japanese-based longline fishery, we find that prices are highly elastic with respect to the freshness of the product, with a 1% decrease in our freshness measure corresponding with a 3.85% decrease in...

Confidence of the Trembling Hand: Bayseian Learning with Data Poor Stocks

Creator:: Holzer, Jorge and Qu, Qian
Abstract:: Management of data-poor fisheries typically relies on setting an annual catch limit (ACL) using catch-based methods that are concerned with estimating a sustainable harvest and hinge on the logic that historic catches reflect a level of exploitation the stock can sustain. The resulting harvest control rules routinely set ACLs at...

Arctic Char Fish Farming in Iceland: Is it a Success?

Creator:: Heimisson, Asgeir Fridrik, Arnason, Ragnar, and Olafsdottir, Gudrun
Abstract:: Fish farming has grown very rabidly during the past few decades. One component of this expansion is the introduction of new species, previously unknown to most consumers, to world markets. Arctic char, a cold water salmonid, is one of these species. In 1987, the total commercial supply only amounted to...

A Gendered Analysis of the Differential Livelihood Impacts of a Closed Fishing Season on Resource Dependent Stakeholders in Tamil Nadu, India

Creator:: Salim, Shyam, Axelrod, Mark, and Novak Colwell, Julia
Abstract:: This research examines the gendered livelihood implications of fisheries management decisions through an exploration of a seasonal ban on fishing. The 45 day closed fishing season on the Eastern coast of India began in 2001 and applies to mechanized boats. While there is existing research on the impact of the...

Some Distributional Consequences of Collective Rights in Artisanal Fisheries

Creator:: Dresdner, Jorge, Gómez, Walter, and Jara, Miguel
Abstract:: This paper analyzes the equity consequences of different fishing quota distributions among artisanal fisher organizations. We develop a basic model to analyze optimal decisions with a collective fishing rights system. With this model as a conceptual framework, using a Theil index as a distributive measure, and employing optimization techniques we...

Measuring the Value of Forage Fish to Recreational Fishermen

Creator:: Hutniczak, Barbara, Lipton, Doug, and Townsend, Howard
Abstract:: Fisheries management has been traditionally single-species oriented. Only recently more pressure has been put on developing a holistic, science-based approach that considers the ecosystem as a whole. This approach is widely known as ecosystem-based fisheries management (EBFM). One of the most often highlighted aspects of EBFM is the relevance of predator-prey...

Value Chain and Price Integration in the Spanish Salted Cod Market

Creator:: Fernandez Polanco, Jose, Bjorndal, Trond, and Llorente, Ignacio
Abstract:: The Spanish market for salted cod has undergone important transformations in recent decades. The collapse of the Newfoundland fishery dramatically reduced local processors’ access to the raw material, which previously was mainly supplied by Spanish vessels. The price of salted cod increased and processors margins decreased. By using price integration...
