Welfare is measured by fish productivity and fish income per cycle and Household Dietary Diversity Score. Our analysis revealed that distance to the sale-point, membership in farmers’ organizations, awareness of pond maintenance benefits, access to information through private extension services, and location were the main drivers behind adopting SA technologies. Results showed that adopting SA technologies increases welfare outcomes of SSA households; however, the non-adopters stand to benefit the most in terms of an increase in welfare outcomes if they adopt the technologies. Our research findings suggested that policies targeted at raising SSA households’ income and dietary diversity can be realized through interventions to raise farmer’s awareness, adoption, and technical know-how about the SA technologies.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44429453","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}

Vietnamese farmers need to efficiently manage their shrimp farming to compete in global markets. This study aims to investigate input- and output-specific technical and scale inefficiencies in Vietnamese shrimp farming practice and their determinants. The research used a survey among 200 shrimp farmers from Ca Mau, Kien Giang, and Soc Trang provinces in Vietnam, and applied a two-stage approach with a Russell-type (input–output) directional distance function for measuring input- and output-specific technical inefficiency, and a bootstrap truncated regression for exploring the determinants of inefficiencies. Results show that main drivers of technical inefficiencies in Vietnamese intensive white-leg shrimp farms are inappropriate management of energy (inefficiency of 32%), seed (inefficiency of 22%) and shrimp yield production (88%). Furthermore, male farmers experienced in shrimp farming, with proper training and applied plastic-lined ponds are generally better in managing pond areas, use of seed, feed, and labor. Technological innovations, better post larvae quality and their stocking management can help to improve shrimp farming performance.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2021-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43539545","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}

In the Northwest Atlantic, interest in sea scallop (Placopecten magellanicus) (hereafter scallop) aquaculture has grown substantially. However, technical and economic challenges have hindered industry growth. We conducted bioeconomic simulations for various sized farms that targeted either live “whole” scallops or the shucked adductor muscle “meat.” The majority of farms selling whole scallops were profitable. However, all farms selling meats generated negative returns. Labor made up the greatest portion of costs in model simulations and increased linearly with farm size, representing a significant bottleneck. Whole scallop farm value was most sensitive to changes in (1) market price and (2) time to market. Our analysis suggests four strategies to increase farmed scallop production in the Northwest Atlantic: (1) mechanize low density net culture, (2) optimize net stocking densities, (3) build site selection tools, and (4) invest in consumer education, end-markets, and biotoxin testing for whole scallops. The sector will require a combination of regulatory, industry, and research cooperation to overcome these pressing challenges, but holds the potential to profitably diversify the bivalve aquaculture industry.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43917873","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 what-if analysis using a deterministic static model to simulate the annual income statement of a typical grow-out farm was carried out. Data was obtained from ten European facilities located in the Mediterranean Sea. Our findings show the importance of the farm’s scale and the production of larger fish to obtain better economic results. Another important conclusion is that increase in fish growth and survival rates, innovating in feed and improving the breeding and health conditions, could compensate the reductions in the sea bass sales prices more efficiently than using other alternatives.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2021-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43569920","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}

This paper analyzes its social acceptance compared to traditional fishing, mainly by applying the structural equations methodology. This technique has been widely used in recent times in social sciences but is minor in this field. We propose a model in which we break down its acceptance in two dimensions: Product and company. We also try to see if there are differences in the perception of men and women. To this end, we have carried out 803 personal surveys in several Spanish coastal provinces. Among the results, we can highlight the good level of acceptance of its products, positively influencing their companies' perception. We can recommend the development of synergies between the different agents involved to improve their acceptance. By gender, general acceptance is higher in men than in women; however, we have not detected significant differences in both groups' perceptions when analyzed using structural equations.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45175688","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}

However, empirical works focusing on low-value species in developing countries are scarcer due to the lack of data. This paper investigates the sources of productivity changes over time using a meta-frontier Malmquist productivity index. The dataset contains 2,100 observations in an unbalanced panel data set for pangas and tilapia in Bangladesh. The results indicate that the overall productivity index and its components increase over time but at a decreasing rate. The technology change effect has the largest impact, followed by technical efficiency change. The scale effects are less than one, indicating that farms are scale inefficient. Nevertheless, the convergence toward the technology frontier seems to level off due to a declining ability to minimize the efficiency change and technological change gaps over time. The results also show a larger disparity among the farms in recent years, lowering the mean technical efficiency, with a few farms driving the frontier outward and the average farms lagging.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2021-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44677286","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}

The multilevel internal instrument variable approach is employed to identify the causal relationships between performance and leverage. Our results show that technical efficiency has been increasing across all firms over the period 2008–2016. The agency-cost hypothesis holds such that leverage has an inverted U-shaped relationship with performance. This implies that leverage increases with efficiency, but efficiency begins to decrease at sufficiently higher levels of leverage. The reverse relationship confirms the franchise-value hypothesis, which states that firms with high efficiency will try to protect the value of their high income by holding more equity capital.

Public listing at stock exchanges can provide improved access and cheaper financing for firms. Since the public listing is a fairly recent phenomenon and relatively few aquaculture firms have entered stock markets, it is useful to investigate the differences in profitability among listed and private aquaculture firms. Our econometric estimates based on a unique panel dataset of Norwegian salmon companies indicate that the sources of profitability, as measured by return on assets (ROA), are different among the two groups of companies. Listed companies are able to increase profitability through working capital optimization; however, they are more negatively affected by operating leverage and liquidity. This indicates that using liquidity as a risk reduction measure is costly in the industry. Although private firms have historically performed better on average in terms of ROA, the difference is not statistically different.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2021-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47761561","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}
