“…This period of development generally requires at least 100 km of river distance with flowing water because the eggs can sink if flow velocity is below 0.2 m/s. Fish numbers in the Yangtze River and associated fishery harvests have been declining due to overfishing, illegal fishing, and water pollution from industrial waste discharge, agricultural chemical runoff, aquaculture, and community sewage (Cao et al, 2008;Ye et al, 2014). The changes of fish early resources since 1997 have shown in Figure 2.…”

“…The richness of omnivorous fish species is reported to increase with decreasing latitude [26]; fish, overall, become smaller, and their abundance is higher [27,28]. In China, crucian carp (Carassius carassius), common carp (Cyprinus carpio), sharpbelly (Hemiculter leucisculus), Sijiao (Toxabramis swinhonis), silver carp (Hypophthalmichthys molitrix), bighead carp (Hypophthalmichthys nobilis), and some smaller-sized zooplanktivorous fish species are common, especially in shallow subtropical lakes [21,29]. A large number of shallow lakes are located in the Yangtze River basin [30] (subtropical zone).…”

How fish communities change with eutrophication in temperate lakes is well documented, while only a few studies are available from subtropical lakes. We investigate the fish community structure in 36 lakes located in the Yangtze River basin, covering a wide nutrient gradient. We found that fish species richness and total fish catch per unit effort (CPUE) increased significantly with chlorophyll a (Chla). Among the different feeding types, the proportion of zooplanktivores increased significantly with Chla, while the percentage of omnibenthivores showed no obvious changes; the CPUE of piscivorous Culter spp. increased with Chla, while their proportion of total catch decreased pronouncedly. Based on the index of relative importance (IRI), the most important and dominant fish species was the zooplanktivorous Sijiao (Toxabramis swinhonis), followed by the omniplanktivorous sharpbelly (Hemiculter leucisculus) and the omnibenthivorous crucian carp (Carassius carassius), a small-sized species belonging to the Cyprinidae family. The CPUE of these three species increased significantly with Chla. The focus has, so far, been directed at large fish, but as emphasized by our results, the abundant small fish species were dominant in our subtropical study lakes even in terms of biomass, and, accordingly, we recommend that more attention be paid to the population dynamics of these species in the future.

“…Chen et al (2011) reported changes in fish assemblages following the completion of TGD. Other studies focused on the reproduction of major commercially important fish such as the major Chinese carp Hu et al 2014) or endangered species (Chen et al 2011;Zhang et al 2014) while some studies focused on heavy metal accumulation (Cai et al 2012;Yi and Zhang 2012) or conservation biology Ye et al 2014). There is a severe lack of research work on trophic ecology of fish related to the TGD construction.…”

Introduction: Damming is one of the dramatic impacts to river food webs due to habitat fragmentation and changes in the hydrological regimes. The world's largest dam, the Three Gorges Dam (TGD), has been constructed in the middle of Yangtze River since 2003. The objective of this study was to understand the effects of altered hydrological regime on the trophic structure of fish food web along the hydrological gradient in the TGD.
