Region policy instruments that transfer funds between jurisdictions are popular tools for mitigating spatial economic disparities. Given the regional aspect of fishing activity, these policy tools often benefit fisheries firms. In this paper, I study the effect of the regional policy area in Norway- a geographical area that is, among...
This is an empirical analysis of the Malindi Ungwana Bay prawn fishery in the coast of Kenya. A resource allocation problem is at the heart of the conflict between artisanal fishers and commercial trawlers exploiting the prawn fishery in the bay. The Prawn Fishery Management plan by the government has...
The small-scale coastal fisheries of Virginia account for a significant portion of the state’s total annual landings and employ thousands of individuals. Despite the value of these fisheries, the number of commercial licenses sold has declined more than 15% since 1994. Declines are attributed to various factors, but indicate potential...
This paper identifies the effect of Mauritian regulation changes on EU industrial vessels’ fishing activities and their implications for food security. The rich resources of Mauritanian waters have historically been utilized by large foreign trawlers, creating small ripple effects and jobs in Mauritania. However, in 2012, Mauritanian authorities introduced new...
Low-value fish/ fishery by-products are potential economic resources for developing animal feeds. Accordingly, fish protein hydrolyzed technology is an excellent way to provide protein sources for animal nutrition. However, the nutritional quality and applying this new feed supplement are severely related to the production stages and next characteristics of agricultural...
Myctophid/lanternfish is one of the major fish stocks in the Oman Sea. The commercial utilization of lanternfish in the Persian side of the Oman Sea began in 2007. The vessels catching the lanternfish have not been specifically designed and equipped for this fishing operation. In addition, the lack of purposeful...
The European Union has set 2021 as the deadline for having a marine spatial plan in place for all its members. Despite the substantial literature analysing the last four decades of MSP implementation worldwide, the quantification of its economic effects remains at early stages. This presentation presents a methodological approach...
The European Union, under the European Maritime and Fisheries Fund, implement the Community-Led Local Development (CLLD). This programme is designed to address the main challenges faced in the fisheries areas by proposing and testing new solutions by the coastal population. In this sense, Spain plays a key role due to...
Iceland adopted an ITQ system for all of its fisheries more than three decades ago. The system has worked well in increasing the economic performance of the fisheries and, at least seemingly, the enforcement of the TACs. The Fisheries Directorate (FD) is aware of the potential problem of discards and...
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...
There is no doubt that policy makers must ensure that the different regulation frameworks contribute to the maintenance of resilient ecosystems that sustain healthy resources for commercial fishers, contributing to the economies that depend on their activity and supply markets with healthy products. However, marine recreational fishing also contributes significantly...
This study was conducted between January 2017 to December 2018 in two fishing communities of Bayelsa and Rivers States, Nigeria. The choice of Imibikiri in Brass local government area, of Bayelsa State and Finima in Bonny Island local government, of Rivers State, was based on accessibility, security, fish production intensity,...
Scientific evidence reveals that renewable resource stock dynamics are subject to uncertainty due to changes in environmental conditions. Despite its critical impacts on management, little is known about the effects of such uncertainty on the formation of regional fisheries management organizations (RFMOs). In this paper, we design a dynamic stock...
Despite the use of gear requirements and access restrictions to manage lobster fishery interactions with north Atlantic right whales since 1997, the population is likely below 370 animals. The Dynamic Area Management (DAM) program (2002–2009) used “real time” right whale sightings data to provide temporary protection using closures or whale-modified-gear...
In the past two decades resource economists have made great headway in understanding spatial-dynamic processes in resource exploitation and management. However, despite this progress, there remain large gaps in understanding the spatialdynamics of recreational resources. Here we first develop a general bioeconomic model of a renewable recreational resource use, under...
Local users may invest in managing common pool resources, thereby promoting social and ecological resilience. Institutional or economic limits on access are regarded as essential preconditions for incentivizing local investments, but we show here that investment incentives can exist even under open access. We modeled a recreational harvest fishery in...
The Cíes Islands show an extremely rich biodiversity, making them the core element of Galicia’s Atlantic Islands, and are an extremely attractive area for the development of small-scale fishing, as well as for tourism and recreational activities, which could constitute a priori a potential risk insofar as maintaining the natural...
Marine recreational fishing (MRF) is a leisure activity and a cultural ecosystem service that, beyond the welfare obtained by its practitioners, has an interesting potential to boost maritime economies. However, it does not represent a formal sector on the national accounts and, in Europe, it lacks a systematic and common...
First-sale prices of fish respond to both local and global drivers, and artisanal fishermen are often considered as price-acceptors due to their limited capacity to influence them, a key issue for their survival and value added creation. However, in artisanal fisheries, the frequent lack of data hinders us from understanding...
The EU framework for the collection and management of fisheries data (EU Reg. 1004/2017) requires estimates of four variables related to capital value and capital cost of fishing fleets, i.e. Consumption of fixed capital, Value of physical capital, Value of quota and other fishing rights, Investments in tangible assets. The...
The valuation marine ecosystem services have been receiving increasing attention in scientific literature, however most of the research is focused in marketed services and does not consider the part of the total economic value. Some services like cultural services that are not direct (touristically) or indirectly marketed as part of...
Iran is among the pioneers in the farming of rainbow trout that is mostly up to 1 kg with a production of 173,000 tonnes in 2018, principally used for domestic consumption. Farmers use labour-intensive hand feeding and counting eggs by hand. Imported trout eggs are preferred to domestic eggs as...
This contribution aims to provide an economic assessment of the seabream and seabass industry in the Mediterranean, in order to describe the recent development and current situation of the economy and markets of this industry. It focuses on analyzing the economic and financial structure at different levels of aggregation (industry,...
The estimation of production frontiers using revenue as the dependent variable is very common in fisheries research since in multi-species fisheries boats catch several species and their output must be aggregated somehow. The objective of this paper is to decompose revenue efficiency into two components, one due to quantities and...
Nigeria with an annual potential of 2.5 million tonnes of fish from aquaculture produced only 316,727 tonnes in 2015 out of the domestic production of 1.027 million tonnes and total fish demand of 3.25 million tonnes. The government has put in place a lot of initiatives to increase aquaculture production...
Fishing systems provide employment, income generation, poverty alleviation, and food security. The coexistence of small-scale fisheries (SSFs) and large-scale fisheries (LSFs) increases management complexity. Management actions have ecological and social implications that must be addressed carefully. We applied a bioeconomic game-theoretical model to the four-gear mullet fishery in southern Brazil—one...
Although aquaculture is the food-production industry that has grown the most in recent years, its companies inherently face more variability in their results than companies from other industries This can be explained by the increasing complexity in their decision-making processes, due to the large number of, external and internal, influencing...
This paper studies the price volatility transmission between the different markets along the value chain of fresh anchovy (Engraulis encrasicolus) in Spain. For this purpose, the prices at the ex-vessel market, the wholesale market and the retail market are considered. As a methodology, a Vector Autoregressive Model (VAR) and an...
Decision-making in aquaculture is becoming increasingly complex due to the need of taking into account large volumes of data, and to consider other aspects besides the economic ones, such as product quality or the environmental sustainability, which are sometimes opposing and difficult to integrate. However, the development of simulation and...

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...
Despite an extensive literature on food-sharing, little attention has been given to the practice in the context of fish harvesting and consumption. We examine it as a possible, almost inadvertent, source of fishery management and we examine its role in trade. Our model is a simple general-equilibrium model of a small costal economy...
The study examined Fish Value Chain (FVC) in Yola area of Adamawa state, Nigeria. Primary data were collected using questionnaire and were analysed using descriptive and inferential statistics. The results showed that female dominate the fish marketing and processing nodes with 79% and 62% respectively while male (77%) dominate the...
When climate change alters the distribution of fish stocks, stocks that were previously owned by a single country can suddenly become shared between countries. Current models predict that in such cases, if no agreement on management is formed, stocks may be severely depleted. A similar problem arises when a new...
