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.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":"25 1","pages":"135 - 158"},"PeriodicalIF":3.9,"publicationDate":"2020-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/13657305.2020.1840663","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48427720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":"25 1","pages":"339 - 366"},"PeriodicalIF":3.9,"publicationDate":"2020-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/13657305.2020.1840661","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43104229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":"25 1","pages":"106 - 125"},"PeriodicalIF":3.9,"publicationDate":"2020-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/13657305.2020.1840662","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42170874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":"25 1","pages":"70 - 88"},"PeriodicalIF":3.9,"publicationDate":"2020-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/13657305.2020.1803446","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46812732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
