Landing Obligation Economic Impact Analysis

Creator:: Mardle, Simon, Metz, Sebastien, Curtis, Hazel, Russell, Jennifer, and Cappell, Rod
Abstract:: Seafish has undertaken an economic impact assessment (EIA) of the landing obligation for key UK fleets targeting demersal stocks. The purpose of the EIA is to provide information that supports decision-making and understanding at a fleet segment, home nation and national level. The EIA has been undertaken in two phases:...

The Future of Aquaculture and Its Role in the Global Food System

Creator:: Anderson, James L.
Abstract:: There are only three fundamental sources for increasing seafood supply: 1) better management and utilization of wild fish stocks, 2) aquaculture and 3) aquaculture-enhanced ‘wild’ fisheries. However, nearly all of the significant growth in global seafood harvest and international trade over the past three decades has, and in the future...

Fishing History Determines Economic Value of Ecological Information in Multispecies Fisheries

Creator:: Essington, T., Sanchirico, J. N., and Baskett, M.
Abstract:: Calls to account for ecological interactions and tradeoffs in fishery management have grown over time. For example, some groups are asking to reduce global forage fish catch by 10-20% to ensure food supplies for other species These efforts follow advances in ecology and the development of large food web models,...

Understanding the Role of Women in Achieving Triple Bottom Line Outcomes for Fisheries Systems

Creator:: Anderson, James L., Chu, Jingjie, Anderson, Christopher M., Garlock, Taryn, and Meredith, Jennifer
Abstract:: Over the past several years we have been developing Fishery Performance Indicators (FPIs) to measure the degree of success fisheries systems have in achieving environmental, economic and community outcomes. We have also developed indicators of key input factors. Among the input factors we have explicitly developed indicators for women’s participation and leadership...

Estimation of Heterogeneous Responses to Size Variation in the Bering Sea Pollock Fishery

Creator:: Chen, Allen and Haynie, Alan
Abstract:: Bioeconomic modeling of an age-structured population typically assumes the value of a fish increases with size; the fish increase in weight as they age, and harvesters may receive an increase in the price per weight. When size selectivity is possible, traditional policy such as individual quotas may still result in...

Disease Risk and Market Structure in Salmon Aquaculture

Creator:: Smith, Martin, Fischer, Carolyn, and Guttormsen, Atle
Abstract:: We develop a model of a multinational firm producing commodities for a global market in multiple locations with location-specific risks and different regulatory standards. Salmon aquaculture and disease outbreaks provide an empirically relevant example. We specifically examine details of the infectious salmon anemia outbreak in Chile in the late 2000s,...

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...

Evaluating the Bio-economic Performance of the Northern Shelf Haddock (Melanogrammus aeglefinus) Fishery Using Age-structured Harvesting Strategies and Variable Growth Trajectories

Creator:: Delargy, Adam, Marshall, Tara, and Needle, Coby
Abstract:: One way to evaluate the bio-economic performance of fisheries is to base the decision to harvest on whether there is a benefit from leaving particular sizes of fish to reproduce or sell them today at market price. This takes into account both size-dependent fecundity and size-dependent pricing, two commonly overlooked...

How to Measure Economic Impacts with Multiple Interacting Policies?

Creator:: Sweeney, Jonathan, Howitt, Richard, Chan, HingLing, Pan, Minling, and Leung, PingSun
Abstract:: We present a positive mathematical programming model (PMP) for Hawaii's longline fishing fleet with the aim of examining the outcome of specific fishery policies. This model expands an earlier model which developed a generalized adaptation of the PMP framework to study fisheries. The current model provides managers with a realistic...
