“…Our results also revealed a positive relationship between freshwater fishery activities and fish species richness (see Figure ) maintained by one of the world's largest annual inland fishery productions (Li et al, ; Wang et al, ). These results were unexpected as fisheries are often presumed to only have a detrimental environmental impact on freshwater fish diversity (Zhao et al, ).…”

“…These results were unexpected as fisheries are often presumed to only have a detrimental environmental impact on freshwater fish diversity (Zhao et al, ). However, the opposite effect as found in this study may be partly explained by effective conservation strategies based on restocking natural systems with freshwater fishes, which typically involves either stock enhancement, which aims to maintain fish populations at a stable level, or multiple releases to increase both the number of recruits and the spawning biomass (Bai et al, ; Li, Liu, Wang, & Silva, ). However, these restocking efforts may have consequences such as the direct or indirect genetic effects to the native populations (Van Zyll de Jong, Gibson, & Cowx, ).…”

“…A more detailed study into the ecological condition and integrity of local fish populations could provide a better insight into the true contribution of fisheries to local freshwater fish diversity. In fact, the world‐leading high production of inland fisheries in China mainly comes from aquaculture and stocking‐based capture fisheries rather than from wild species‐based capture fisheries (Chen et al, ; Li et al, ).…”

“…China is one of the largest developing countries with the densest human population (i.e., around 151 people per km 2 , http://worldpopulationreview.com/) and a large and rapidly developing economy with growth rates averaging 6% over 30 years (IMF Report, ; National Bureau of Statistics of China, ; Yu, Zhang, & Liu, ). China is also the global leader in freshwater fisheries and aquaculture production (i.e., 41.1% over the 1950–2015 period) (Wang et al, ; Zhao, Gozlan, & Zhang, ), with almost all natural and man‐made water bodies used for various freshwater fishery activities (Li, Liu, Wang, & De Silva, ; Wang et al, ). However, these human pressures on the environment are not evenly distributed across all Chinese regions and significant regional socio‐economic differences persist (Deng, Huang, Rozelle, & Uchida, ; Kang et al, ; Liu & Diamond, ).…”

“…The Yangtze River Economic Belt (YREB), one of the largest economic zones of China, has significantly higher economic growth and population density in the eastern and coastal subregions than those in the western and inland subregions (Chen et al, ). In addition, fishery activities are mostly located in central provinces along the middle and lower reaches of the Yangtze River basin (Li et al, ; Wang et al, ). Due to the large amount and regional imbalance of economic growth and fishery activities, these human stressors are often thought to be the main drivers of freshwater fish diversity changes in China (Hulme, ; Kang et al, ; Xing, Zhang, Fan, & Zhao, ).…”

Understanding drivers of freshwater fish assemblages is critically important for biodiversity conservation strategies, especially in rapidly developing countries, which often have environmental protections lagging behind economic development. The influences of natural and human factors in structuring fish assemblages and their relative contributions are likely to change given the increasing magnitude of human activities. To discriminate natural and human drivers of fish diversity and assemblage patterns in developing countries with rapid socio‐economic development, a dataset of 908 freshwater fish species and 13 metrics including three categories of both natural (i.e., biogeographic) and human drivers (i.e., economic growth, inland fisheries) in China were analysed with machine learning algorithms (i.e., self‐organizing map, random forest). Here, we found that biogeographic drivers explained 21.8% of the observed fish assemblage patterns in China and remained stronger predictors when compared to human drivers (i.e., 15.6%, respectively). Freshwater fish species richness was positively correlated to rainfall, air temperature, surface water area and inland fisheries production but negatively correlated with urbanization. In addition, the strong structuring effects of climatic variables on Chinese fish richness patterns suggested that the fish assemblages could be particularly vulnerable to climate change. Our results showed that natural biogeographic factors still dominate in driving freshwater fish assemblage patterns despite increased human disturbances on aquatic ecosystems in a rapidly developing country. These findings consequently suggested that we should consider both natural (e.g., climate) and human (e.g., urbanization, inland fisheries) factors when establishing aquatic conservation strategies and priorities for developing countries that are experiencing rapid socio‐economic changes.

When more is more: taking advantage of species diversity to move towards sustainable aquaculture

Human population growth has increased demand for food products, which is expected to double in coming decades. Until recently, this demand has been met by expanding agricultural area and intensifying agrochemical‐based monoculture of a few species. However, this development pathway has been criticised due to its negative impacts on the environment and other human activities. Therefore, new production practices are needed to meet human food requirements sustainably in the future. Herein, we assert that polyculture practices can ensure the transition of aquaculture towards sustainable development. We review traditional and recent polyculture practices (ponds, recirculated aquaculture systems, integrated multi‐trophic aquaculture, aquaponics, integrated agriculture–aquaculture) to highlight how they improve aquaculture through the coexistence and interactions of species. This overview highlights the importance of species compatibility (i.e. species that can live in the same farming environment without detrimental interactions) and complementarity (i.e. complementary use of available resources and/or commensalism/mutualism) to achieve efficient and ethical aquaculture. Overall, polyculture combines aspects of productivity, environmental protection, resource sharing, and animal welfare. However, several challenges must be addressed to facilitate polyculture development across the world. We developed a four‐step conceptual framework for designing innovative polyculture systems. This framework highlights the importance of (i) using prospective approaches to consider which species to combine, (ii) performing integrated assessment of rearing environments to determine in which farming system a particular combination of species is the most relevant, (iii) developing new tools and strategies to facilitate polyculture system management, and (iv) implementing polyculture innovation for relevant stakeholders involved in aquaculture transitions.
