Indonesian tuna fisheries are complex due to variation in the scale of fleet in the fisheries, their multi-species nature and problems with data collection. Moreover, like many developing-country fisheries, their management needs to take into account many other goals besides rents maximization, such as the distribution of rents and the...
Nigeria’s domestic supply of fishery products falls short of the demand; however, there is a growing aquaculture industry that has come to the rescue in filling the gap between supply and demand. Most of the aquaculture fish farmers are prone to the risk of climate change, since weather and extreme...
Most of fish farmed by small scale producers in developing countries is sold directly to local markets without passing through a processing industry. Besides problems related to sanitary requirements, this situation highlights the low added value retained by fish farmers. In Brazil, the integration between small scale fish farmers and...
The paper focuses on the combination of the cooperative fisheries management with the non-cooperative literature. It has important modeling contributions by creating a new framework on co-management. The structure of the model is repeated coalition game with the possibility to deviate combined with introduction of a variation of a club...
Quantitative fish stock assessment methods have become increasingly complex. However, the quality of available data may still restrict their applicability, being a particular concern in data-poor situations and where management decisions rely on either commercial fisheries or scientific survey data. In this study we address this issue by proposing a...
What is the impact of the recent spike in Eastern Atlantic and Mediterranean bluefin tuna catch on the global price of bluefin and its substitutes? Will boosting the eastern bluefin quota even further benefit the fishing industry? And who stands to win and lose from supply increases? Using a novel...
Under the IIFET 2018 Special Session “Tools for Stock Assessment, Economic Fishery Analysis, and Risk Assessment for Sustainable Management Strategies of Data Poor Stocks in Mixed, Small Scale and Indigenous Fisheries” a number of stakeholder presentations addressed the current status, challenges, needs and future perspectives for implementation of management and...
Ocean health is a major concern for coastal communities dependent on the ocean for their livelihood. Recent changes in in ocean health force researchers to examine the factors that influence the decline in ocean health. The paper developed production functions using the Global Ocean Health Index (OHI) for 2014 and...
Stated preference (SP) methods such as contingent valuation and choice experiments are often used to estimate values associated with marine and coastal ecosystem services. However, applications do not always apply best practices, leading to questions regarding the validity and relevance of welfare estimates. This presentation outlines contemporary best-practice recommendations for...
A vessel-based bio-economic model (IAM) is presented and applied to the Bay of Biscay sole fishery to investigate alternative quota management systems from a multi-criteria perspective. For this study, the model integrates several institutional arrangements related to catch share management. The current French co-management system with non-transferability of quota is...
Although the formal process of Brexit has started, there is high uncertainty about Brexit’s impacts on the future of demersal mixed fisheries in the North Sea. As migratory demersal stocks (e.g. cod, haddock, hake and saithe) traverse the zones of various countries, one challenging issue is to agree on how...
Regulators in many countries have adopted quotas as a means of dealing with the open access problem inherent in fisheries. Unit quotas for the Norwegian purse seine fleet were introduced in 1996 but consolidation of licenses has been in place since 1978. The current Norwegian regulatory system does allow for...
Using theoretical trade model of generali equilibrium, the paper consider non-cooperative decision of interior solutions of fishery amounts and resource price under integrated market price as constraints. The paper proved non-existence of interior solitions equilibrium under the conditions with very generalized robustness in not only stationary equilibrium but also transition...
The fisheries sectorof Sri Lanka means of livelihoodfor 2.6 million peopleand the vast majority of themare involved in small scale fisheries. The study was taken up with the objectivesof to identify social &political membership status of small scale fishery value chain members, to assess the level of decision making power...
The fisheries sector faces the challenge of determining effective management, in an ecosystem perspective in order to mitigate the Global Warming Potential (GWP).The main focus of the study was to analyze the resource utilization in the value chain of Maldives fish processing and the environmental performances of the steps involved....
Any fisheries governance system is made up of policies and institutions in the broad sense of the term that govern the sector. When a system of governance is unsatisfactory, in particular because of the inadequacies and dysfunctions of these policies and institutions, and the way in which public action is...
Historically, cod fishing along the coast of northern Norway has been about fishing as much as possible with the least possible resource effort. This traditional logic is rooted in biology (cod’s migration pattern), meteorology (weather conditions) and traditional capture technology (small and not as seaworthy boats). The logic is further...
This study identifies differences in fishing efficiency of vessels operating in the Nha Trang purse seine fishery in Vietnam. The deterministic DEA methodology is used to assess relative capacity utilization of the fishing fleet. Double bootstrap DEA method is adopted to overcome some of the drawbacks of nonparametric DEA methodology...
