Abstract The marine recreational fishing industry in Florida has an economic impact of $7.6 billion dollars, which includes the expenditures of its 2.4 million licensed anglers. Interest in developing aquaculture techniques for marine baitfish species have served as an impetus for recent research; however, market data in Florida has not been investigated and described in over two decades. 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.
摘要佛罗里达州的海洋休闲渔业产生了76亿美元的经济影响,其中包括240万持照垂钓者的支出。对开发海洋饵鱼养殖技术的兴趣推动了最近的研究;然而,20多年来,佛罗里达州的市场数据一直没有得到调查和描述。本次调查的目的是评估和描述佛罗里达州养殖的细鳍鱼(Lagodon菱形)和猪鱼(Orthoristis chrysoptera)的活海洋诱饵鱼市场。一项调查被设计并分发给佛罗里达州37个沿海县的280家诱饵零售商。该调查旨在收集对市场评估至关重要的信息。调查问题的重点是出售的饵鱼种类、野生饵鱼的缺点、首选饵鱼的特性、对水产养殖和养殖饵的看法,以及侧重于鳍鱼和猪鱼数量和购买习惯的具体问题。共有代表31个县的119项调查被退回,回复率为42.5%。这项市场调查的结果将为目前和潜在的生产商提供宝贵的资源,他们将向佛罗里达州沿海的零售商销售活的海洋诱饵鱼。

Abstract This study assessed the impact of tilapia farming on poverty in the States of Oaxaca, Guerrero, and Chiapas, which have the highest levels of poverty in Mexico. The study uses both 2018 data from a sample of micro- and small-sized farmers in these States, and the Mexican government’s multidimensional poverty methodology. Results show fewer tilapia farmers in extreme or moderate poverty compared to the general population’s value in the municipalities and States where these farms are located, therefore asserting the positive impact of the activity. While cage farmers have more social rights deprivations, their income is greater compared to that of tank and pond farmers. Tilapia projects are also relevant to food security, increasing both household fish and animal-protein consumption.
本研究评估了墨西哥贫困程度最高的瓦哈卡州、格雷罗州和恰帕斯州罗非鱼养殖对贫困的影响。该研究使用了2018年这些州微型和小型农民样本的数据,以及墨西哥政府的多维贫困方法。结果显示,与罗非鱼养殖场所在城市和州的一般人口相比,处于极端或中等贫困状态的罗非鱼养殖户较少,因此肯定了该活动的积极影响。虽然笼养农民的社会权利被剥夺更多,但他们的收入比池养和池塘养的农民要高。罗非鱼项目也与粮食安全有关,增加了家庭鱼类和动物蛋白消费。

Economic history of U.S. catfish farming: Lessons for growth and development of aquaculture 美国鲶鱼养殖的经济史:水产养殖增长和发展的经验教训

Abstract Catfish farming continues to be the largest segment of U.S. aquaculture, and U.S. catfish farmers have demonstrated resilience and resourcefulness in adapting to changing economic conditions. 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.
摘要鲶鱼养殖仍然是美国水产养殖的最大部分,美国鲶鱼养殖户在适应不断变化的经济条件方面表现出了韧性和足智多谋。商业生产始于20世纪50年代至60年代,20世纪70年代的增长带来了加工和营销方面的挑战。到20世纪80年代初,关键的生产、加工和营销环节已经到位,将鲶鱼养殖转变为一家大型企业。关键包括开发高效曝气器、营养完整的饲料、提供全年鱼类供应的多批次生产、加工创新,以及创建用于营销和公共关系的鲶鱼研究所(TCI)。向非传统鲶鱼市场的成功扩张吸引了美国海鲜进口商从越南进口的pangasius鲶鱼的竞争,这得益于成功的营销计划。2003-2013年美国工业的萎缩是四次外部经济冲击的综合影响;价格周期低谷;2001年经济衰退;9·11恐怖袭击;以及越南进口的pangasius。价格跌至历史低点,并在3年内一直低于生产成本。2014年至2019年,采用降低成本的强化系统(分流池、强化曝气)实现了稳定增长。美国水产养殖的经验教训包括鱼种/种子技术、农民协会、研究、推广、营销和州/联邦支持的重要性。

Abstract This study examined the impact of climate change adaptation strategies on the welfare status of aquaculture fish farmers in Southwest, Nigeria. Multistage sampling procedure was used in the selection of 288 respondents. To account for selection bias due to both observable and unobservable factors where more than two options arise, the multinomial endogenous switching regression model was used to analyze the collected data. 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%. It is, therefore, recommended that policies which promote adoption of climate change adaptation strategies (especially stocking time adjustment and bore-hole construction being the strategies with the highest impact) should be formulated since they are capable of increasing welfare of aquaculture fish farmers.
摘要本研究考察了气候变化适应策略对尼日利亚西南部水产养殖户福利状况的影响。采用多阶段抽样方法选取288名调查对象。为了解释由于两个以上选项出现的可观察和不可观察因素造成的选择偏差,使用多项内生转换回归模型分析收集的数据。实证结果表明,受教育程度高的地区采用钻孔施工、放养时间调整和筑堤作为气候变化适应策略的概率增加。采用放养时间调整和筑堤措施,粮食安全指数分别提高了106.1和16.9%。此外,在收养者类别中采用放养时间调整将贫困差距缩小了87.2%。因此,建议制定促进采取气候变化适应战略的政策(特别是放养时间调整和钻孔建设是影响最大的战略),因为它们能够增加水产养殖户的福利。

Abstract The shrimp industry plays a leading role in aquaculture development in Vietnam. Currently, the government is running a credit subsidy program to support farmers investing in improved production methods. 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. These findings suggest that to promote better investment in improved production methods, the government should focus on the regulatory framework, monitoring and control of environmental impacts, and reevaluate the size of the credit subsidy.
虾产业在越南水产养殖发展中起着主导作用。目前,政府正在实施一项信贷补贴计划,以支持农民投资改进生产方法。本文旨在调查白腿虾养殖者对改进生产方法的投资意愿,并使用离散选择实验来检验当前政府对该部门的政策是否符合养殖者的偏好。结果表明,农民并不关心环境影响,而是强调增产和更成功的作物是他们投资意愿的主要驱动因素。目前的补贴利率与农民要求的利率不匹配。这些发现表明,为了促进对改进生产方法的更好投资,政府应关注监管框架,监测和控制环境影响,并重新评估信贷补贴的规模。

Abstract In this paper, we study the factors that influence consumer attitudes toward aquaculture as well as annual expenditure on aquaculture products. Our analysis is composed of two parts. First, we estimate the effects of several covariates of interest on annual seafood expenditure using a two-way censored regression model, due to the nature of the survey data. Our results indicate that consumers who are college-educated, aware of aquaculture operations in their area, and more aware about where their seafood is produced tend to spend more on farm-raised seafood. Second, attitude indices are used as dependent variables in three distinct logit regressions, one for each of the respective seafood categories, i.e., finfish, shellfish, and sea vegetables. For both the finfish and shellfish regressions, the results suggest that being older, being more informed about East Coast aquaculture operations, desiring at least state-level detail for production location, and looking closely at seafood labels more frequently were all associated with a lower probability of having a negative attitude toward aquaculture. Few explanatory variables had statistically significant effects in the sea vegetable regression, which is likely due to the low number of respondents in our sample aware of sea vegetable aquaculture operations (approximately 23%).
摘要本文研究了影响消费者对水产养殖态度的因素以及对水产养殖产品的年支出。我们的分析由两部分组成。首先,由于调查数据的性质,我们使用双向删节回归模型估计了利息的几个协变量对年度海鲜支出的影响。我们的研究结果表明,受过大学教育的消费者,了解其所在地区的水产养殖业务,更了解其海产品的生产地点,倾向于在农场养殖的海产品上花费更多。其次,在三个不同的logit回归中,态度指数被用作因变量,分别用于各自的海鲜类别,即鳍鱼,贝类和海洋蔬菜。对于鳍鱼和贝类的回归,结果表明,年龄越大,对东海岸水产养殖操作了解越多,希望至少了解生产地点的州级详细信息,更频繁地仔细查看海鲜标签,对水产养殖持负面态度的可能性越低。很少有解释变量在海菜回归中具有统计显著的影响,这可能是由于我们样本中了解海菜养殖操作的受访者数量较少(约23%)。

Abstract Regional economic assessments (REAs), including economic contribution and impact analyses, are often used in resource-based industries to inform policymakers, elected officials, and the general public of an industry’s role within the regional economy. However, REAs have been difficult to conduct for the aquaculture industry due to issues with data availability and quality. This paper will provide an overview of economic contribution analysis, the challenges associated with applying these analyses to U.S. aquaculture production, and techniques to overcome these challenges. The Florida shellfish aquaculture industry is used as an example to highlight some of the data issues and how using different methods within a REA can lead to inaccurate representations of an industry’s economic contribution.
区域经济评估(REAs),包括经济贡献和影响分析,通常用于资源型产业,以告知政策制定者、民选官员和公众该产业在区域经济中的作用。然而,由于数据的可得性和质量问题,很难对水产养殖业进行区域评估。本文将概述经济贡献分析,将这些分析应用于美国水产养殖生产所面临的挑战,以及克服这些挑战的技术。以佛罗里达州贝类养殖业为例,强调了一些数据问题,以及在REA中使用不同的方法如何导致对行业经济贡献的不准确表述。

Abstract While there in general appears to be public support for shellfish aquaculture operations, the construction of oyster farms often meets opposition where an important argument is devaluation of housing property. This makes it important to study the effect of construction of oyster farms on property value. In this paper house sales data from Rhode Island between 2000 and 2013 is analyzed to evaluate the effect of oyster farm construction on property values using a difference-in-difference (DiD) approach within a hedonic price model (HPM). Given the use of sales data this study focuses on the perceptions of people in the housing market. We found that the impacts are more nuanced and complex: overall on average the construction of oyster farms increased the value of the houses located closer to the farm. When the houses are grouped by their value category, however, our results show that the value of luxury houses decreased significantly.
摘要虽然公众普遍支持贝类养殖,但牡蛎养殖场的建设经常遭到反对,其中一个重要论点是房地产贬值。这使得研究牡蛎养殖场建设对财产价值的影响变得重要。本文分析了2000年至2013年间罗德岛州的房屋销售数据,以使用特征价格模型(HPM)中的差异法(DiD)评估牡蛎养殖场建设对房地产价值的影响。考虑到销售数据的使用,本研究侧重于人们对住房市场的看法。我们发现,影响更为微妙和复杂:总体而言,牡蛎养殖场的建设平均增加了离养殖场更近的房屋的价值。然而,当房屋按其价值类别分组时,我们的结果表明,豪宅的价值显著下降。

Shared waters—shared problems: The role of self-governance in managing common pool resources 共享的水资源-共享的问题:自治在管理公共池资源中的作用

Abstract Seafood production governance, primarily and traditionally a governmental activity, is increasingly designed and performed by private actors, such as business organizations and/or Non-Governmental Organization. This is often seen as complementary to public regulation in handling collective problems, but there are few studies within the aquaculture sector which investigate the extent and potential of such arrangements. The aim of this paper is to study self-regulation among groups of fish farmers as a means to solve collective challenges in the commons and to derive lessons for future cooperative arrangements. Using data from the Norwegian salmon industry, we investigate the extent of private self-regulated collaborations, the motivation for collaboration, and the self-reported obstacles. We further elucidate the strengths and weaknesses of such arrangements, both regarding day-to-day operations and in times of crisis. The findings show that private self-regulation plays an important role in increasing available resources in addressing common challenges and coordinating the production to limit negative externalities. However, such arrangements cannot work in isolation and need to be aligned with the role and functioning of public authorities. In fact, the looming shadow of the state is an important prerequisite for the successful role of such arrangements.
海产品生产治理,主要和传统上是一项政府活动,越来越多地由私人行为者设计和执行,如商业组织和/或非政府组织。这通常被看作是对处理集体问题的公共管制的补充,但是在水产养殖部门内很少有研究调查这种安排的程度和潜力。本文的目的是研究养鱼户群体之间的自我调节,作为解决共同挑战的一种手段,并为未来的合作安排提供经验教训。利用挪威鲑鱼产业的数据,我们调查了私人自我监管合作的程度、合作的动机和自我报告的障碍。我们进一步阐明这种安排在日常业务和危机时期的长处和短处。研究结果表明,私人自我调节在增加可用资源以应对共同挑战和协调生产以限制负面外部性方面发挥着重要作用。但是,这种安排不能孤立地发挥作用,需要与公共当局的作用和职能保持一致。事实上,若隐若现的国家阴影是这种安排成功发挥作用的重要前提。
