Abstract Trade credits provide financing to buyers who might not, otherwise, be able to operate a business. However, sellers may use trade credits to exploit market power and this introduces a market failure that reduces efficiency and social welfare when compared to a competitive market. The objective of this study is to investigate the costs of trade credits for fish feed to fish farmers in Bangladesh

Rural fish farming is being promoted as a good source of protein and income diversification to fight poverty and inequality. However, its actual contribution to these rural households and local com...

Abstract A sample of 2,185 Ghanaian households from the GLSS6 was examined using a latent class model of structural heterogeneity in a linear regression framework to assess their fish consumption patterns. The results suggest that Ghanaian households fall into two consumption categories, namely “traditional” and “non-traditional” households, though there is some overlap between the two household groups

Abstract Geographical concentration of industries tends to be important for firms that depend on innovation and are intensive in the use of specialized technology and labor. In this paper, we investigate the interaction between agglomeration and trade performance in the Norwegian aquaculture industry. We include a variable for regional clustering in a standard gravity model and estimate its impact

Abstract This study address whether different sustainability initiatives by the companies listed at the Oslo Seafood Index impact company value. With signaling theory as framework, it is argued that sustainability reports and other initiatives may contribute to reduce the information asymmetry between managers and equity holders. Using financial data from the company’s annual reports in combination

Abstract The U.S. catfish aquaculture industry has undergone a continuous and alarming contraction over the last 15 years or so. The rapid increase in cheaper imports, which has coincided with the decline in the domestic catfish farming industry, is being blamed by industry commentators as a major cause of the decline. The impact of increased market share of imports on prices is of particular significance

Abstract Concerns that additional supplies of U.S. farm-raised fish may compete with domestic wild fish has contributed to resistance and litigation that has slowed aquaculture development in the U.S. We employ a contingent choice experiment to large seafood wholesalers and suppliers in the U.S. to investigate market potential of new farmed finfish species from the Gulf of Mexico. We estimate probabilities

Abstract The aquaculture sector in Malawi has not shown significant growth in terms of production and productivity. This study applied the translog stochastic frontier to determine the technical efficiency in tilapia production in Malawi. Multi-stage sampling procedure was used to select 211 tilapia farms for the study. The determinants of tilapia output in Malawi are seed, fertilizer input and farm

Abstract This paper discusses how transaction data can be used to shed light on trade dynamics in seafood exports, with Norwegian salmon exports as the case. There is a large literature on exports and imports of salmon between countries, but less is known about how the heterogeneity of exporters and importers relates to the aggregate data. We utilize transaction data for all exports of salmon in the

Abstract This study analyzes fresh and brackish water aquacultures—especially carp, tilapia, and shrimp production—in major Asian aquaculture-producing countries. Different indicators have been used, involving dimensions that may be affected by climate change. High diversity is believed to indicate high adaption capacity, while resilience is estimated by known biological properties of each species

Abstract The Norwegian salmon farming sector has experienced an increase in industry concentration for the last 20 years attributed to agglomeration externalities and scale economies; big firms increase their size and market share while small firms remain operating at the minimum level. However, small firms have higher profitability ratios than their bigger counterparts, a fact that contradicts economic

Abstract The ever-growing industry of farmed warm-water shrimp in developing countries claims the continued expansion of export markets in developed countries, where they form a growing share of markets traditionally supplied by wild-caught shrimp. In this market transition, developing countries can benefit from knowledge regarding the consumer valuation of shrimp attributes to reasonably target product

Abstract Land-based farming of salmon is emerging for a number of reasons. The demand for salmon is increasing in many parts of the world. In recent years there has been limited growth in production due to binding government regulations and environmental challenges in sea-based salmon aquaculture. This is true both for Norway (sea lice, salmon escapes) and Chile (sea lice, disease problems), the two

Abstract Sea bass (Lates calcarifer) is a key aquaculture species in Malaysia, produced as part of a polyculture system in cages but predominantly as a single species in ponds. The production of sea bass in Malaysia has decreased substantially since 2015. Several studies suggest disease may be the main cause for such decline, but changing economic conditions may also have played a role in this decline

Abstract Theoretical and empirical research on farm management suggests that management practices and managerial ability affect farms’ financial performance. However, the explicit application of these concepts is scarce within the aquaculture field. In this study, the impact of management practices and managerial ability on the financial performance of aquaculture farms are investigated in Bangladesh

Abstract This study examines Bangladesh fish farmers’ perception for risk sources, risk management strategies, and the relationship with socio-demographic variables. Data were collected from a sample of 350 farmers in Bangladesh. Exploratory factor analysis of a set of perception measurement items was used to assess farmers’ attitudes towards risk and their risk management strategies. The results reveal

Abstract We assess the financial performance of an Atlantic salmon (Salmo salar) monoculture versus an Atlantic salmon, blue mussel (Mytilus edulis), and sugar kelp (Saccharina latissima) Integrated Multi-Trophic Aquaculture (IMTA) operation. Using updated methods and models, we improve on earlier studies of IMTA economics. A discounted cash-flow analysis was used to assess the profitability of hypothetical

Abstract The aquaculture sector is a capital intensive production process where access to credit is helpful in order to develop and manage farms in developing countries. Nevertheless, a supply of credit is often not readily available, which is creating credit constraint situations. This study investigates how credit constraints affect the productivity of aquaculture farmers in Bangladesh. An endogenous

Abstract The L46 (Hypancistrus zebra) stands out as one of the most valuable Amazonian species in the international market for ornamental fish and faces a notable problem: the risk of extinction versus the demand for new specimens for aquariums. Considering that breeding in captivity can be a conservational tool for aquatic species and an alternative source for generating income, the objective of the

Abstract Recently, a great deal of research has focused on culturing marine baitfish for the recreational fishing market but there is limited information on the marine bait industry. Developing protocols required to culture marine baitfish is important, but information is also needed on the baitfish retail market. This research presents the results of a recent survey of Texas bait stands regarding

Abstract The study investigates the efficiency of a sample of Italian aquaculture firms according to their legal status, size, and location. An efficiency analysis was conducted for a sample of 160 units using an output-oriented Data Envelopment Analysis. The average value of the efficiency scores reveals that it should be possible to significantly increase firm performance. The most inefficient farms

Abstract According to governmental plans, Norway faces huge expansions in the production of farmed Atlantic salmon. However, it is municipalities that designate coastal areas to aquaculture activities and their motivation depends on net benefits at municipal level from such use. Yet, there is little empirical evidence on costs and benefits of using coastal areas to aquaculture activities. We set up

Abstract Often, increases in farmed seabass and seabream production surpluses from Turkey and Greece have been blamed to lead to price declines and aquaculture sector crises. In this study, we investigate whether Turkish exports of farmed European seabass affect prices of European Union (EU) farmed European seabass. This is done by examining the existence of market integration between the prices of

Abstract In this paper, a time-varying student-t copula is used to capture information on price volatility dependence in the short-, medium-, and long-run horizon in the US market for frozen and fresh salmon, trout, tilapia and catfish. Using monthly data from July 1992 to March 2017, the volatility dynamics for these aquaculture species are assessed. The analysis allows indicating significant differences

Abstract This article provides econometric estimates of the determinants of collaboration in innovation processes and innovation outcomes in Norwegian aquaculture and other seafood sector firms, using linked innovation survey and register data on individual firms for the years 1990–2010. The seafood sector in Norway has an extensive innovation system and a high research and development (R&D) intensity

Abstract Certification schemes are becoming increasingly important within aquaculture management, but the indicators that are used by these schemes are subject to considerable debate. Many have questioned their actual impact on improving the industry, and whether they effectively address the many externalities of aquaculture production. In this paper, we study the choice of indicators in eight major

Abstract Enteric Septicemia of Catfish (ESC) is a ruinous bacterial disease affecting the U.S. catfish industry. Previous attempts to develop ESC vaccines have failed to achieve industry acceptance, largely attributed to difficulties in delivering the vaccine to immunocompetent fish. Recently, a live attenuated ESC vaccine has been developed, coupled with a mechanized platform designed to accurately

Abstract This article analyzes the effects of agglomeration externalities on productivity and efficiency by applying a stochastic production frontier model with a technical inefficiency model to the aquaculture industry. Agglomeration externalities refer to the costs and benefits to firms from clustering. Agglomeration studies within aquaculture have focused on the intensive salmon industry, whereas

Abstract This paper investigates how pricing efficiency of Norwegian salmon exports varies across destination market characteristics. Efficiency is defined as the rate at which individual transaction prices adjust to common market information, and is estimated by dynamic fixed effects panel models with parameters conditional on trade attributes using micro-level trade data. Our results show that contract

Abstract While export-oriented shrimp farming has become an important source of income for many small-scale farmers in developing countries, the rate at which products are rejected at the ports of developed countries has remained high mainly due to the overuse of antibiotics. To reveal what determines the overuse of antibiotics, we interviewed 201 shrimp farmers in Viet Nam in 2015 and collected shrimp

Abstract Integrated aquaculture systems have the potential to enhance the environmental sustainability of aquaculture production, if economically feasible. Data from integrated tilapia-prawn production trials were used to develop economic-engineering enterprise budgets for ponds with and without substrate that targeted two different types of markets, using two production scales and two forms of land

Abstract Since 2005, Norwegian salmon farmers have experienced increasing unit costs, contrasting pre-2005 trends characterized by innovations, rapid productivity growth, and diminishing unit costs. This article investigates these cost changes using a panel of salmon producers. The drivers behind cost changes in the industry are identified for the period of 2001–2014 using a flexible cost function

Abstract We measure the impact that sanitary treatments that control ectoparasite Caligus rogercresseyi abundance have on unit production costs of Salmo salar farms in Chile. We follow complete production cycles for a sample of farms between 2009 and 2015. We estimate a simultaneous salmon biomass growth and Caligus abundance model. The statistical analysis determines the effect of antiparasitic treatments

Abstract Despite the growing popularity of culture-based fisheries (CBFs) associated with village irrigation systems (VISs) in Sri Lanka, there is less knowledge about factors that influence productivity levels. CBFs compete with rice for access to water in the VIS, so maximizing the efficiency of CBFs is essential to ensure that the limited water resources are used most effectively. To address this

Abstract We investigate empirically market interactions in the Turkish wild and farmed sea bass and sea bream markets. For gilthead sea bream and European sea bass, we conduct a Granger causality test between the prices of the wild and farmed products, based on the estimation of a vector autoregressive model. Our data set consists of annual fish prices from 1996 to 2016. Our empirical results show

Abstract Volatility in catfish pond bank and feed prices lead to profit uncertainty in the catfish industry. Analysis of the factors that affect those prices and development of a forecasting model would provide guidance to catfish farm managers. Error-correction models (ECM) based on cointegrating relationships among variables were specified following development of a single-equation ARIMAX model.

Abstract While there have been a number of studies investigating the market integration between farmed and wild seafood, the relationship in terms of volatility has received little attention. However, with the high degree of market integration for similar species, one would also expect substantial volatility spillover. In this paper, we investigate the price volatility relationship between seafood

Abstract The stringency of the regulatory environment has been shown to negatively affect the growth of aquaculture. A technical efficiency analysis of baitfish/sportfish production in the United States was performed using a stochastic production frontier model and a jointly estimated maximum-likelihood procedure (Frontier 4.1). Determinants of inefficiency were assessed for their relationship to farm

Abstract The risk of norovirus food poisoning from oyster consumption can be minimized by consumers, as thorough cooking can destroy norovirus. This paper uses data from 23 prefectures in Japan during 1970–2010 to examine how the demand for oysters responds to this manageable risk. We find that the incidence rate of norovirus has no effect on the price of oysters in prefectures that specialize in oysters

Abstract Australia banned imports of uncooked prawns from Asia in early 2017 after an outbreak of the deadly white spot disease in southern Queensland. The ban expired after 6 months, and it remains unclear what the source of the epidemic was, or the mechanism through which it may have entered the country. The Queensland State Government offered financial assistance to selected producers, although
