Modelling a Small-Scale Sea Cucumber Fishery in Yucatan

Creator:: Hernández-Flores, Alvaro
Abstract:: The status of many sea cucumber fisheries in the world is overexploited. Some of the reasons are: an increase in demand from China, the distance of these fisheries to China, and the high rate of fisheries development. Most sea cucumber fisheries are small-scale with a simple management system. To overcome overexploitation,...

Reputation as a Central Resource to Create Social Networks and Market Transactions. The Case of Mercado del Mar in Guadalajara, Mexico

Creator:: Pedroza-Gutiérrez, Carmen and Hernández, Juan M.
Abstract:: Fish consumption in Mexico is considered low (around 12 kg per person per year) and non-homogeneously distributed across the country. One of the reasons for this situation is the scarcity of wholesale selling sites. In this context, the Mercado del Mar (MM), located in Guadalajara city, Jalisco, is the second...

The Influence of Network Properties on the Agility of Seafood Supply Chains

Creator:: Hernández, Juan M. and Pedroza-Gutiérrez, Carmen
Abstract:: The fisheries supply chains integrate multiple and heterogeneous agents linked through commercial (buyer/seller) relationships. In a large and competitive trade market, every agent can choose his/her partners, but the functioning of the supply chain depends on the aggregation of every agent's decisions that configures the global network of relationships. In...

The Cost of Avoiding Sea Cucumber Stock Depletion

Creator:: Hernández-Flores, Alvaro, Cuevas-Jiménez, Alfonso, and Aranda-Nah, Javier
Abstract:: In 2013 a stock of sea cucumber (Isostichopus badionotus) was discovered in northern shelf of Yucatan. A survey calculated a biomass of 17,600 tons. The species has an attractive price for local fishers, therefore, in order to avoid the “race for sea cucumbers” and the collapse of the stock, authorities...

Quantitative Relationship between Resazurin and Respiration in Stream Ecosystems

Creator:: Gonzalez-Pinzon, Ricardo, Haggerty, Roy, Argerich, Alba, Acker, Sarah, and Myrold, David
Abstract:: After three decades of active research in hydrology and stream ecology, the connection between solute transport, stream metabolism and nutrient dynamics is still unresolved. This existing gap obscures the functionality of stream ecosystems and how they interact with other landscape processes. To date, determining rates of metabolism is accomplished with...

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...

Co-Management of a Recreational Fishery with a Social-Ecological Approach

Creator:: Palomo, Leopoldo and Hernández Flores, Dr. Alvaro
Abstract:: Most regulations for recreational fishing in Mexico focus primarily on offshore boat fishing. However, regulations for inshore recreational fishing in Mexico are insufficient. Every year hundreds of European and American fishermen visit Punta Allen, Mexico to practice fly-fishing. Punta Allen is a coastal village located in the Sian Ka'an Biosphere...

Socio-Economic Analysis of the Results of Implementing a Rights-Based Management System in a Small-Scale Fishery in the Gulf of California: The Gulf Curvina

Creator:: Ortiz-Rodríguez, Rafael, Yee-Sánchez, Silvia, Fraire-Cervantes, José A., Olivares-Bañuelos, Nadia Citlali, Licón-González, Héctor, and Rodríguez-Harker, Laura F.
Abstract:: Annual socio-economic surveys, pared with third-party landing monitoring data, have allowed a multi-year analysis of the economic impacts and perceptions of implementing an individual vessel quota rights-based management system in the gulf corvina (Cynoscion othonopterus) fishery. This fishery is targeted by four communities, including an indigenous one, in the Upper...
