Smallholder fish farming contribute to improved nutrition, incomes and livelihoods of rural
communities. Despite the potential, aquaculture in most rural areas is based on extensive
production systems characterized by low availability in inputs. In Nyaguta, farmers are involved
in agricultural production activities, including fish farming. However, most farmers do not...
The aim of the paper is to explore the economic environment that makes informal fish trading possible, the nature of these activities and how they are interconnected or might stimulate IUU fishing activities in the port of Progreso, Yucatan, Mexico. The main argument is that fish trading by middlemen has...
Capture fisheries and aquaculture in freshwater bodies play a very important role and is considered to have great potential for augmenting fish production as well as diversification of livelihoods in both Cambodia and Vietnam. In Cambodia, inland fisheries remain primary importance in the fisheries sector, while aquaculture is more important...
The linefish sector is one of the 10 commercial fisheries in Namibia. This sector is made up of two subsectors: commercial right holders and angling. The angling subsector is further divided into two types of fishing activities; subsistence angling which serve as a source of food supply and recreational angling...
With the economic globalization, the consumption demand of Chinese residents has changed gradually. The paper analyzes consumption tendency of Chinese residents from two aspects, those are per capital consumption level and consumption characteristics. On the one side, per capita ownership of fish and fishery products of China is above the...
Ecolabelling has become an essential component of the global sustainable seafood trade. The MSC is currently the world leader in certification and ecolabelling programs for wild capture fisheries. While the environmental benefits of certification have been widely recognised, its economic benefits are often anecdotal or unknown. The South African hake...

This paper presents key lessons from development of a transboundary fisheries co-management (TFC) on Lake Chiuta, shared between Malawi and Mozambique. Since the mid-1990s when fisheries co-management was introduced on the Malawian side of the lake, there had been conflicts between fishing communities from both countries. The conflicts mainly centred...
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...

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...

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...
The National Oceanic and Atmospheric Administration (NOAA) executes a number of activities that support a more holistic way of studying and managing marine resources, namely an ecosystem-based approach to management (EBM). This presentation will provide an overview of NOAA’s Integrated Ecosystem Assessment (IEA) program as well as Large Marine Ecosystem...
As fisheries management is increasingly required to consider the full impacts of their operations, this work seeks to define the relationship between fishing effort and interactions with listed endangered species. The study employs logbook data containing over 64,000 sets, matched with observer data from 2008 to 2015 in an undisclosed...
Strategies for increasing production of goods from working and natural systems have raised concerns that the diversity of species on which these services depend may be eroding. This loss of natural capital threatens to homogenize global food supplies and compromise the stability of human welfare. We assess the trade-off between...
Fishers exploit populations that are heterogeneously distributed in space and time without full knowledge of species distributions and with fishing gear that is not fully selective. The ability to change catch composition is limited by species mix at a particular location and time and the capture characteristics of the fishing...
Catch shares are being increasingly adopted worldwide to halt overfishing and improve ecosystem outcomes. Rights-based fisheries management generates economic efficiency, and fishers with a financial stake in the fisheries are believed to have the incentive to become ecological stewards. However, the empirical evidence shows no significant impact of catch share...
Protected areas (PAs) are important for biodiversity conservation and can provide the benefits for current and future generations. Management effectiveness is a key factor to achieve outcomes of PAs. However, success is related to the enforcement implemented. Corruption is one of the main issues impacting and weakening enforcement. This article...
We present a bottom-up analysis of the proportion of global marine fisheries subsidies to small-scale fisheries (SSF). Using existing data, we split the reported national subsidy amounts into the fraction that goes to small- compared to large-scale fishing sectors. Results reveal a major imbalance in subsidy distribution, with SSF receiving...
Lake Michigan is the only Great Lake that supports an economically viable salmonid population, but a collapse may be on the horizon. Biomass of Chinook Salmon, the most popular sportfish in the region, decreased by 70 percent between 2013 and 2015. The decline is thought to be irreversible. Managers must...
Almost all recent empirical literatures that study the subjective wellbeing of fishers lack of relevant control as they are only based on surveys among fishers. Therefore, they cannot really answer whether being a fisher generate higher or lower life satisfaction, after controlling for other aspects of life. This study is...
In this paper we discuss dynamic adjustment paths towards economic optimal steady-state equilibrium in a fishery where two species interact through a traditional predator-prey relation. We set-up a general bio-economic predator-prey model based on the assumption that fishing effort is a public input applied when exploiting the fish stocks. By...
Marine recreational fishery plays an important role in developing marine economy and traditional fishery transformation. Recently the development of Marine recreational fishery has hit a bottleneck, traditional marine recreational fishing industry needs rapid change. Marine recreational fishery new format as an existing form of Marine recreational fishery industry has opened...
There are a range of smaller-scale fish farms operating in Ghana producing mainly tilapia and catfish based on extensive (stocking of small reserviours), intensive and semi-intensive (earthen ponds & tanks) techniques. Aquaculture production in Ghana plays a significant role in the economic development of livelihoods of fish farmers and contributes...
