Abstract When markets are integrated and the law of one price holds, prices confronted by different producers should tend to uniformity, in the long run, allowance is made for differences in quality and transportation costs. However, how producers coordinate to align prices is not obvious and probably the answer will vary between markets. In this article, we investigate this question using salmon prices differentials, for the main export countries—Canada, Chile, Norway, and the United Kingdom—of farmed Atlantic salmon in the United States market. The results indicate that there is a single common stochastic trend for the prices of the main suppliers of farmed Atlantic salmon in the United States market. Moreover, the Law of One Price cannot be rejected, implying that farmed Atlantic salmon from the different producers are perfect substitutes for U.S. consumers and that markets are fully integrated. Finally, testing for price leadership, we find that the main exporters follow the lead of the least cost-efficient producer, the United Kingdom.

Abstract This study has examined consumers’ acceptance, preference, and willingness to pay (WTP) for five newly developed convenient (ready-to-cook) catfish products. The University of Arkansas at Pine Bluff, in collaboration with Texas State University and USDA Agricultural Research Services, New Orleans, has developed these products. We have collected data from 121 catfish consumers of Arkansas through 18 experimental auction sessions (Vickrey’s second-price auction). Participants evaluated the products’ sensory attributes (appearance, color, glossiness, and serving size). They elicited their WTP for each of the products through bid (quoted price) in separate sealed envelopes. Consumers’ acceptance of various product attributes was measured using a hedonic scale (Likert scale) and just about right (JAR) scale. We have measured consumers’ preferences for the products and their attributes through two-way internal preference mapping (Principal Component Analysis) and three-way internal preference mapping (Parallel Factor Analysis—PARAFAC). We have examined the role of consumers’ acceptance level for product attributes and the participants’ socioeconomic characteristics on their WTP using the Tobit model. The study revealed that the acceptance level for panko-breaded products was higher than marinated products. Consumers preferred breaded products to marinated products. The WTP for a product was higher with the higher acceptance ratings for product attributes, young participants, and African–American catfish consumers. There was a negative relation between the participants’ education level (dummy for bachelor’s degree holders) and their WTP. The study concluded that all the newly developed catfish products are likely to be successful as future seafood products in the market.

Abstract The Theory of Planned Behavior (TPB) has so far found few applications in aquaculture research. Using Rogers’ innovation adoption characteristics as a complementary framework, we explore its relevance in describing Indian carp farmers’ perceptions of the attributes of fish feed containing non-conventional ingredients (seaweeds, freshwater macrophytes, microalgae and microbes), and in understanding the factors influencing their intention to use these feeds. We find that fish farmers familiar with manufactured feed tend to have more positive attitudes to the inclusion of non-conventional ingredients in fish feed than those who are not. Perceived peer pressure, importance and benefits from the novel aquafeed, perceived comparative advantage and uncertainty regarding outcomes from its use are the main determinants of intention to adopt the proposed feed innovation. The combined application of the TPB and Rogers’ innovation framework provides valuable insights into fish farmers’ attitudes and behavioral intention toward innovation adoption, and we recommend its wider use for designing interventions that promote technological innovations and improved farm management. By exploring the underpinnings of intention to adopt an innovation, our study contributes to the literature on fish farmers’ behavior and attitudes to innovations in aquaculture.

Abstract The value chain for farmed salmon has experienced substantial changes over the past decades as a result of innovation in production technology, logistics, distribution and marketing that have helped facilitate the rapid production growth. The high level of control over the production environment in principle makes it possible for Atlantic salmon to be tailored on a number of product attributes or dimensions in response to requirements from different customer groups. However, when compared to meat production, differentiation in farmed salmon remains limited, pointing to a still immature industry. Based primarily on interviews with Norwegian producers, we offer an overview of the prominent differentiation strategies today and discuss barriers to further differentiation.

Abstract Sea cage farming of seabream and seabass is the most important form of aquaculture production in the Mediterranean Sea. Despite the continuous global growth in aquaculture production and demand, the economic performance of seabream and seabass companies has not followed the same trend. In recent years, companies have faced successive periods of market instability, with high volatility in supply and market prices that have strongly affected their operational margins. Despite the regional importance of this industry, only a handful of studies have examined the economic performance of these farms. In this paper, we investigate the technical efficiency and scale effects of Mediterranean aquaculture farms. Furthermore, environmental impact in terms of nutrient emissions from the farms is examined and discussed. Technical efficiency effects are analyzed using Data Envelopment Analysis (DEA), and the bootstrap procedure is used for bias correction. The results show that the mean technical efficiency could be improved by between 16% and 34%, and scale efficiency suggests that farms could improve their efficiency by operating at an optimal scale. Compared to measurements in previous studies, the environmental variables show that the emission of nutrients from the farms per kilo of fish produced has not changed over the past twenty years. Finally, policy implications suggest that more attention toward improving technical efficiency may help improve the robustness of the sector and that environmental regulation might be needed in order to improve the environmental performance of farms.

Abstract Aquaculture production of turbot in Galicia (Spain) has grown significantly in the last 35 years. The evolution of the sector and the variations in its production technologies are the result of the confluence of different phenomena such as horizontal integration, the arrival of foreign investment or the independence of imported inputs. This article analyses the evolution of Galician-farmed turbot sector production. Five main factors (space, technology, production, marketing and environment), and profitability are studied and analyzed. The results show that the average rate of return in the sector has increased significantly over the last years.

Abstract In recent years, European producers of cultured sea bass and sea bream have experienced a highly competitive market with low prices that have caused profitability challenges. An important factor of economic competitiveness for firms is to produce efficiently. In this paper, technical efficiency of European producers of cultured sea bass and sea bream is evaluated for the period 2008–2017 using the stochastic production frontier (SPF) approach. In addition, the effect of a set of specific-firm factors on firms’ efficiency is investigated. The majority of firms in the sample were found to have a technical efficiency over 90% with Cypriot and Greek firms being, on average, the most efficient. We also found evidence that the technical efficiency of these firms is positively related to their size. Moreover, the high degree of average efficiency means that further production growth requires innovations that move up the production frontier.

Abstract The farmed salmon supply chain in Europe is changing. There is a growing concentration at intermediary levels in the supply chain and more product differentiation in the market. This means that different price determination processes could apply in various product sub-markets. In this study, price transmission relationships in the salmon value chain were investigated at two different product levels. Specifically, a relatively unprocessed salmon product (fresh salmon) and a more processed product (smoked salmon) were investigated since processing costs might have a significant impact on a vertical price linkage. A threshold cointegration model was applied to estimate the price transmission between the Norwegian export market and the retail markets of France and Spain. The results indicated a price transmission relationship along the fresh salmon chain in both markets; but not along the smoked salmon chains in either market. Furthermore, for the fresh salmon value chain, asymmetric adjustment was observed in both markets.

Abstract U.S. catfish producers have been exploring the adoption of alternative-production technologies (intensive-aeration, in-pond raceways, and split-pond systems) in recent years for achieving cost efficiencies. A multi-state (Alabama, Arkansas, and Mississippi) survey was conducted to identify specific reasons influencing the decisions of producers whether or not to adopt these alternative catfish production technologies. High yield and greater control over the production process were the major reasons for the adoption of alternative catfish production technologies. High investment costs and increased risks associated with these technologies were the main reasons for not adopting new technologies. Early adopters had significantly larger farms, greater numbers of ponds, and a significantly greater percentage of use of hybrid catfish. Econometric analysis suggested that characteristics of the technology such as productivity, perceived risk, and adoption costs, influenced early adoption decisions. Institutional factors such as prior involvement in Extension/research programs and farm characteristics of the scale of operation also shaped adoption decisions. Understanding the characteristics (of the technology, farms, and producers) that lead to greater adoption, may provide guidance to increase the rate of successful transfer of new technologies to fish producers.
