This study is based on a large-scale survey of practices of aquaculture operators in Cambodia, Laos, Myanmar, Thailand, and Vietnam. Climate-related risks to profits of aquaculture farms in the Mekong Region are typically managed alongside water-related, disease and other business risks. Farmers who were more concerned with risks to profitability had a history of undertaking more risk management practices. Farmers growing shrimp (rather than fish), or adopting more intensified production systems, had more risk management practices. Wealthier and more educated farmers had experience with more practices for dealing with current risks, as well as recognized the need for strategies to adapt to a changing climate in the future. Information access is a factor in the adoption of new practices and strategies. Adoption of aeration or use of information-communication technologies to manage climate-related risks, for example, was more likely among more educated and wealthy farmers who belonged to growers’ groups. The findings also suggest that attitudes toward innovation, levels of investment and social norms influence adoption of technological, organizational and informational practices.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":"25 1","pages":"388 - 410"},"PeriodicalIF":3.9,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/13657305.2021.1917727","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44467873","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 species Atlantic salmon dominates the global salmon market, but its two largest producers, Norway and Chile also farm in sea pens significant quantities of large rainbow trout (as opposed to portion-sized Rainbow trout farmed in freshwaters in other parts of the World, e.g., Iran, Peru, Turkey, and others). Suggesting that these trout have some attributes that make it a useful complement to Atlantic salmon. We investigate development in supply volumes of these species and conduct a cointegration analysis using monthly prices from 2000 to 2018. The results show that the markets for fresh and frozen rainbow trout are tightly integrated with fresh Atlantic salmon, and, where the latter is a price leader. This means that many consumers consider the two products as substitutes, with no clear preferences. There is no apparent productivity argument for the continued production of rainbow trout vis-à-vis Atlantic salmon. However, there may exist a fringe of consumers that prefer its characteristics, motivating firms to maintain its production as a means of diversification.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":"25 1","pages":"159 - 176"},"PeriodicalIF":3.9,"publicationDate":"2021-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/13657305.2020.1857469","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45187179","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}

Moreover, allocative inefficiency, implying the inappropriateness of input mixes—given their respective prices—was found to be the primary cause of cost inefficiency in this aquaculture. The result from bootstrap truncated regression in the second stage suggested that lower input levels of chemicals/drugs and fingerlings and higher input levels of feed used per ha may help to increase the cost-efficiency of shrimp farming.

However, farmers are facing challenges due to increasing environmental problems in rivers used as the primary source of water in aquaculture pond production. To deal with these challenges, farmers have organized co-management communities, which gives them a stronger voice among river users. This study investigates the effects of co-management on technical efficiency and environmental stressors using a second-stage Data Envelopment Analysis model. Environmental stressors are identified through interviews with 306 farmers in eight sub-districts, of which two are practicing co-management. The results show that farmers in areas with co-management have relatively high technical efficiency after taking other drivers into account. Furthermore, the farmer’s technical efficiency seems to be less affected by the identified environmental stressors. In conclusion, co-management could be used as a tool to improve technical efficiency and limit stress factors for farmers. It could be initiated by the farmers themselves or by policymakers and natural resource managers and could improve the livelihoods of small-scale shrimp polyculture farmers.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":"26 1","pages":"98 - 117"},"PeriodicalIF":3.9,"publicationDate":"2021-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/13657305.2021.1897190","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41561999","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 objectives of this survey were to evaluate and describe the live marine baitfish market for cultured pinfish (Lagodon rhomboides) and pigfish (Orthopristis chrysoptera) in Florida. A survey was designed and distributed to 280 bait retailers in 37 coastal counties of Florida. The survey was developed to gather information vital to market evaluation. Survey questions focused on baitfish species sold, shortcomings of wild baitfish, preferred baitfish characteristics, perception of aquaculture and cultured bait, and specific questions with an emphasis on quantities and purchasing habits for pinfish and pigfish. A total of 119 surveys representing 31 counties were returned for a 42.5% response rate. The results of this market survey will serve as a valuable resource for current and potential producers who market live marine baitfish to retailers throughout coastal Florida.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":"26 1","pages":"57 - 76"},"PeriodicalIF":3.9,"publicationDate":"2021-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/13657305.2021.1893864","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42324891","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}

Commercial production began in the 1950s–1960s, with growth leading to processing and marketing challenges in the 1970s. By the early 1980s, the key production, processing, and marketing pieces were in place to transform catfish farming into a major enterprise. Keys included development of efficient aerators, nutritionally complete feeds, multiple-batch production providing year-round supply of fish, processing innovations, and creation of The Catfish Institute (TCI) for marketing and public relations. The successful expansion into nontraditional catfish markets attracted competition of pangasius catfish imported from Vietnam by U.S. seafood importers, free riding on successful marketing programs. The 2003–2013 contraction of the U.S. industry was the combined effect of four external economic shocks; trough of price cycle; 2001 recession; September 11 terrorist attacks; and Vietnamese pangasius imports. Prices fell to historical lows and remained below production cost for 3 years. Adoption of intensive systems (split ponds, intensive aeration) that reduced costs led to steady growth from 2014 to 2019. Lessons for U.S. aquaculture include the importance of fingerling/seed technologies, farmer associations, research, Extension, marketing, and state/federal support.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":"26 1","pages":"1 - 35"},"PeriodicalIF":3.9,"publicationDate":"2021-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/13657305.2021.1896606","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49345154","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 empirical findings revealed that level of education brought about increase in the probability of adopting bore-hole construction, stocking time adjustment and embankment creation as adaptation strategies to climate change. Also, adoption of stocking time adjustment and embankment creation by the adopters increased food security index by 106.1 and 16.9%, respectively. Furthermore, adoption of stocking time adjustment in the adopters’ category reduced the poverty gap by 87.2%.

This paper aimed to investigate white-legged shrimp farmers’ willingness to invest in improved production methods and to examine whether the current government policy for the sector is in line with farmers’ preferences using a discrete choice experiment. The results show that farmers do not care about the environmental impacts but emphasize increased yields and more successful crops as the main drivers of their willingness to invest. There is a mismatch between the current subsidized interest rate and farmers’ required interest rate.
