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...

A Quantitative Approach to Determine Cardiovascular and Neurodevelopment Risks and Benfits from Methylmercury and Omega 3 Fatty Acids in Fish Consumed in the Columbia River Basin

Creator:: Cusack, Leanne, Harding, Anna, Kile, Molly, Harper, Barbara, and Stone, Dave
Abstract:: Background: Fish are an important part of a well-balanced diet as it contains high quality proteins, as well as polyunsaturated fatty acids that are known to play an important role in human health. Consumption of fish, however, is the primary route of exposure to methylmercury in humans. A quantitative risk-benefit...

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...

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...

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...

The Creation of Shared Value by Exploiting Synergies of Marketing Tools in Seafood

Creator:: Chapela, Rosa, Santiago, José L., and Fernandez, Mercedes M.
Abstract:: The concept of shared value has been defined by Porter and Cramer as those policies and operating practices that enhance the competitiveness of a company while simultaneously advancing the economic and social conditions in the communities in which it operates. This concept guides a coordinated process of stakeholders' engagement to...

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...

Stock Proxies in Efficiency Analysis of Fisheries

Creator:: Duy, Nguyen Ngoc and Flaaten, Ola
Abstract:: This study proposes three methods for technical efficiency (TE) estimation using three different fish stock proxy measures while applying the stochastic production frontier (SPF) approach. We apply these methods to two Vietnamese offshore fisheries, gillnet and hand-line, for which measures of stock abundance are unavailable. Based on the assumption of...
