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...
Choices are often limited as the most popular alternatives reach capacity and sell out; thereafter, selection is over less preferred choices. In the context of nonmarket goods, willingness to pay (WTP) welfare measures provide an estimate of the value of characteristics – often calculated through the modeling of preferences using...
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,...
Notwithstanding the increasing use of area and seasonal closures to promote the sustainable use of coral reef fisheries, few studies have examined the socio-economic performance of these management strategies. This study describes small-scale fishermen's views regarding the biological and socioeconomic performance of these management tools off Puerto Rico. Our findings,...
Based on financial risk analysis and portfolio theory, this paper aims to estimate the underlying risk of the European fish quota distribution among European member States along the time. Firstly, we have assigned a fishing portfolio to each member state (FP(jt)) and its related value based financial portfolio (FPV(ijt)), where...
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...
In this paper, we analyze how public monitoring and enforcement (M\&E) efforts affect the success of a collective property right. We develop a bioeconomic model to generate several theoretical predictions, which we test empirically by assembling and analyzing novel data on public patrolling and fishing activity in the Chilean abalone...
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,...
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...
The way of individual (fishing) quota is now widely recognized as a useful way for fishing resource management. However, even in the (internationally) shared resources, distributions of non-transferable fishing quota for each country should be justified, shouldn't be? The research considers the logistics "to begin with" in the theoretical international...
