“…Overall, economic growth, technical innovation, grower's education, production scale, and environmental protection are often found to be crucial determinants of aquaculture's technical efficiency (Asche et al, 2009; Fernández Sánchez et al, 2020; Rahman et al, 2020; Scuderi & Chen, 2018) and ecological efficiency (Du et al, 2021; Zhang et al, 2021). Therefore, we aim to investigate these factors' impact on the efficiencies of Chinese aquaculture industries.…”

Promoting the productivity and environmental sustainability of aquaculture is critical in ensuring its healthy development. This study assesses freshwater aquaculture's technical efficiency and ecological efficiency in China's 19 inland provinces from 2008 to 2019, aiming to reveal its productivity and environmental sustainability status. We employ the three‐stage Data Envelopment Analysis‐CCR (T‐DEA‐CCR) and three‐stage Slack‐Based Measure‐DEA (T‐SBM‐DEA) methods to explore the technical efficiency and the ecological efficiency while accounting for environmental conditions and random errors. The average technical efficiency and ecological efficiency during 2008–2019 are 0.857 and 0.702, respectively, indicating substantial scope for enhancing the productivity and environmental sustainability of China's inland aquaculture. We further investigate the regional development using the club convergence, finding that the provincial‐level technical efficiencies have already achieved population convergence while the ecological efficiencies diverge into two clubs, suggesting that Chinese freshwater aquaculture's productivity and environmental sustainability have different development pathways. Acknowledging the pivotal roles of environmental protection and growers' training in aquaculture's productivity and environmental sustainability, policymakers may institute funding and recognition to foster the adoption of innovative, environmentally responsible practices by operators.

“…In the case of aquaculture, carp polyculture (a suitable composition of silver carp, catla, rohu, common carp, mrigal, sarputi, and grass carp suggested by previous studies [29][30][31]), mixed culture of freshwater giant prawns with carp polyculture (e.g., [32][33][34]), and Asian stinging catfish or shingi monoculture (e.g., [35][36][37]) were practiced in order to produce a greater amount of fish while following sustainable environment-friendly aqua- In contrast, none of the control farmers received any support and no change was carried out in their homesteads (Figure 3c-f). They were only asked to provide baseline data and other seasonal production data.…”

Waterlogging is a major problem in the south-western region of Bangladesh; this study was conducted in the eight most affected areas in order to enhance agricultural production by applying Land- and Water-based adaptive and alternative Farming Practices (LWFP). The study was designed to support target (research) farmers by raising one part of their homestead to use for living and agricultural farming, with the other part excavated to store rainwater and use for aquaculture. The study selected two groups of control farmers: those with ponds and those without. The study was conducted in two phases (i.e., phase 1—pilot phase and phase 2—extended phase), with each year divided into three cropping seasons: summer, rainy, and winter. The study found that the research farmers’ income was significantly higher from vegetables (both pilot and extended phases: p < 0.001), dike crops (both pilot and extended phases: p < 0.001), fish (both pilot and extended phases: p < 0.001), livestock (pilot phase: p < 0.01 and extended phase: p < 0.001), and poultry (pilot phase: p < 0.05 and extended phase: p < 0.001) compared to the control farmers. Moreover, the research supported the empowerment of women, which was not found in the control farms. Overall, the research program was embraced by the local communities as a very successful model. Furthermore, the study showed how waterlogging marginally affects very poor people, and that they can cope with this severe problem by adopting various farming practices. Therefore, the application of this research approach is suggested for similarly affected areas.

“…A Färe-Primont index approach was used to analyze the efficiency of aquaculture with regard to the 'Gher' aquaculture system in Bangladesh. It was discovered that the total factor productivity increased by 0.86% per year, mainly driven by technological changes of 0.54% per year and assorted efficiency changes of 0.06% per year [24]. Data envelopment analysis, combined with the double-bootstrapping technique, was used to analyze the cost and technical efficiencies of intensive shrimp farming in Ningshun, Vietnam.…”

Aquatic products are important sources of protein and food consumption, which are pivotal to solving the problem of food shortage. As the world’s largest producer of aquatic products, China’s aquaculture has developed rapidly. However, a large quantity of pollutants has also been generated in the fish farming process, which is detrimental to the sustainable development of China’s aquaculture. Therefore, under double constraints with regard to resources and the environment, fishery development must achieve cleaner production. Measuring green total factor productivity in aquaculture is fundamental to improving aquaculture production efficiency and reducing pollution emissions. This paper investigated the green total factor productivity in China using the SBM-ML method and analyzed the dynamic evolution of fish farming, measuring its change characteristics with regard to time and spatial differences. The results indicated that the total factor productivity indexes of mariculture and freshwater aquaculture in China are 1.050 and 1.060, respectively. Regionally, mariculture in the East China Sea region has the highest green total factor productivity of 1.072, followed by the South China Sea region with 1.056, and the green total factor productivity in the Yellow Sea region is the lowest—only 1.030. The results of the freshwater aquaculture calculations showed the opposite geographical distribution characteristics in China, with the highest in the western region (1.098), followed by the central region (1.046), with the lowest being in the eastern region (1.038). Evidently, both mariculture and freshwater aquaculture have noticeable spatiotemporal heterogeneity. Relevant policy recommendations are provided to improve the green production efficiency of fishery.
