“…Despite this development, the application of this technique for estimating Farrell (1957)'s technical efficiency has thus far been limited in aquaculture. For our best knowledge, there are only the works of Chang et al (2010), Asche et al (2013), , Lam Anh et al (2018) and Hai Au et al (2018) used the single bootstrap for correcting bias in estimation of technical efficiency (see Sharma &Lueng, 2003 andIliyasu et al, 2014 for reviewing technical efficiency studies adopting DEA in aquaculture before the year of 2010; and Table 1 below for this decade).…”

The paper adopts the bootstrap procedures proposed by Simar and Wilson for data envelopment analysis to analyze technical efficiency in aquaculture. The data of 318 intensive shrimp farming households in the south-central coast of Vietnam is used as a case for analysis. The result demonstrates that the null hypothesis of constant returns-to-scale is rejected in favour of variable returns-to-scale for the production technology.Moreover, the potential improvement is certainly greater using bootstrapping than that using the conventional data envelopment analysis, which has been adopted widely in the aquaculture literature for technical efficiency estimation. By adopting the double bootstrap proposed by Simar & Wilson (2007), the bias-corrected technical efficiency is 0.69, and at the 95% confidence interval with the lower limit of 0.65 and the upper limit of 0.75. In addition, factors that might statistically positive influence technical efficiency in this farming are larger farm size, having access to formal credit; whereas negative influences are cultural length.

Economic efficiency analysis of fish farming in Bharatpur District, Rajasthan: A corporate social responsibility (CSR) initiative

et al. 2022

The innovative corporate social responsibility (CSR) initiative of Lupin Human Welfare and Research Foundation, Bharatpur, Rajasthan, India, through fish farming in Kaman Block of Bharatpur has transformed the lives of the local population. Fish farming started with 240 families in 1980, is now benefiting 2000 people and has brought economic and social transformation in this region. Cost-benefit analysis indicated that fish farmers culturing Indian major carps (IMC) for 18 months from spawn to table size registered a benefit-cost ratio (BCR) of 2.15. The fish farmers who cultured IMC for 12 months (from fingerlings to table size ) achieved a BCR of 1.77. The results of data envelopment analysis (DEA) showed that the technical efficiency was around 0.95, indicating highly efficient farms. Polluted water, disruption in power supply and poaching were found to be major constraints faced by the farmers. Keywords: Constraint analysis, Costs and returns analysis, Data envelopment analysis, Indian major carps

“…Accordingly, we defined a dummy variable to capture the extensive margin of the aquaculture farm in the non-fishery labor market. It has been well documented that aquaculture production is associated with the severe problem of land subsidence in Taiwan [4,6,12]. Since one research objective in this paper is to examine whether the use of marketing channels has any impact on environmental quality, we defined a dummy variable to indicate if the fishery farm used groundwater as the major water source in its aquaculture production.…”

“…Finally, since it has been well documented that aquaculture production has resulted in severe land subsidence problems by pumping groundwater during production in Taiwan, we examined the externality of producers' use of different marketing channels on the use of groundwater in aquaculture production. This part of the analysis sheds light on the relationship between marketing strategy and environmental sustainability because aquaculture production has resulted in serious pollution and land subsidence [4,5]. Due to the scarcity of fresh water in Taiwan, the over-pumping of groundwater in aquaculture production is common, making Taiwan a good study area for addressing this topic [6].…”

Can Direct Marketing Increase Fishery Profitability and Environmental Quality? Empirical Evidence of Aquaculture Farm Households in Taiwan

Marketing strategies play a significant role in determining farm income. Although direct marketing has been proposed as an innovative way to improve producers’ economic welfare, little is known about producers’ adoption of direct marketing among aquaculture farms. This study examines the adoption of wholesaler markets, individual wholesalers or shippers, and direct marketing among aquaculture farms. In addition, we quantify the effects of the use of different marketing channels on fishery revenues, profits, and production inputs. A sample of 25,180 aquaculture family farms in Taiwan was drawn from the fishery census survey. After estimating the simultaneous equation system model, we find that the use of multiple marketing channels generates the highest fishery revenues, which highlights the importance of marketing channel diversity on selling fishery products. Moreover, we find a positive effect of direct marketing on fishery revenues and profits. We also find that the use of direct marketing can reduce the use of groundwater in aquaculture production. Since the decrease in groundwater use can mitigate the severity of land subsidence, this paper provides evidence that direct marketing can possibly provide a win-win strategy to improve fishery producers’ revenues and environmental quality.
