Abstract:: The trans-boundary migration of fish stocks creates spatial externalities, and hence, makes international cooperation beneficial. This study provides a model for the management of straddling and highly migratory fish stocks and examines the relationship between fish migrations and the benefits from cooperation. Previous studies on trans-boundary fish stock management have...

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...

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...

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...

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,...

Abstract:: This study investigates harvesters’ effort in terms of days at using dynamic discrete choice model. Fishing effort as a form of time has been analyzed with trip level data, in which only averaged daily catch is available. On the other hand, daily level data enables us to have the variation...

Abstract:: By 2015 The European Common Fisheries Policy Reform includes a landing obligation (discard ban) in some fisheries and over the next few years all EU fisheries will be facing the landing obligation restriction. This is one of the most significant changes of the Common Fishery Policy (CFP) since 1983, the...

Abstract:: 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...

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...
