Abstract:: Tilapia exports to the US have been claimed to double in the last three years following the two bans on Vietnamese catfish imports in November 2001 and June 2003. The aim of these bans was to restrict imports from the major exporter of Catfish (Vietnam) reducing competition for US catfish...

Abstract:: Ideally, we seek to develop perfectly integrated ecological-economic models, drawing on the best data, modeling and knowledge of each of the disciplines, into one coherent model to inform policy. The realities of achieving such are thwarted by data and model compatibility issues. For example, ecological data may be available on...

Abstract:: Tilapia is one of the fastest growing aquaculture species in the world. It is produced and consumed in all continents and in more countries than most other species, making the market more heterogeneous than for other successful aquaculture species such as salmon and shrimp. This paper investigates the degree of...

Abstract:: This study investigates the economic impact to fisheries and associated sectors if wild fisheries continue operating to 2030 without considering the effects of climate change. Estimates of climate change impacts in Australian fisheries and their associated probability distributions were derived from the literature and expert consultations. An Input- Output model...

Creator:: Norman, Ana, Pascoe, Sean, and Theaubaud, Olivier
Abstract:: Climate change is expected to impact the productivity of wild and farmed fisheries worldwide. These impacts will vary by region and consequently affect differently the supply to markets. Market driven interactions between fisheries from different regions and between different target species means that changes in supply from one region or...

Abstract:: As changes in climate and corresponding ocean shifts threaten U.S. fisheries with uncertain change, West Coast marine scientists and fishery management institutions have newly emphasized ecosystem-based analysis and management. The development of the West Coast-specific California Current Integrated Ecosystem Assessment (CCIEA) has accordingly allowed for economic analyses and the social...

Abstract:: Marine scientists and policymakers are encouraging ecosystem-based fishery management (EBFM), but there is limited guidance on how to operationalize the concept. We develop a method for EBFM based on financial asset management that uses the joint probability distribution of species in an ecosystem. Illustrating our method with the Chesapeake Bay,...

Abstract:: In multi-species fisheries managed under ITQs, the existence of joint production may lead to complex catch-quota balancing issues. Previous modelling and experimental research suggest that, in such fisheries, some fishers may benefit from the ability to trade packages of fishing quotas, rather than fulfill their quota needs by simultaneously bidding...

Abstract:: Incorporating catch or harvest rate information in repeated-choice recreation fishing demand models is challenging, since multiple sources of information may be available and detail on how harvest rates change within a season is often lacking. This paper develops a framework for evaluating which source(s) of information should be used to...

Abstract:: To examine the impact of the Landing Obligation (LO) on the Irish fishing industry and explore possible mitigation strategies, we carried out two trials on commercial fishing vessels in 2015. One vessel targeted Nephrops, the other mixed demersal whitefish in Irish waters. The study was in two phases. In month...
