Mesocosm experiment reveals a strong positive effect of snail presence on macrophyte growth, resulting from control of epiphyton and nuisance filamentous algae: Implications for shallow lake management.
Liu Yang,Hu He,Baohua Guan,Jinlei Yu,Zongbao Yao,Wei Zhen,Chunyu Yin,Qianhong Wang,Erik Jeppesen,Zhengwen Liu,Zhengwen Liu +10 more
TL;DR: It is suggested that in shallow aquatic ecosystems, herbivorous snails reduce the negative impact of nutrient loading on submerged macrophyte growth, by controlling both epiphyton and nuisance filamentous algae.

Changes in Pelagic Fish Community Composition, Abundance, and Biomass along a Productivity Gradient in Subtropical Lakes
Jinlei Yu,Wei Zhen,Lingyang Kong,Hu He,Yongdong Zhang,Xiangdong Yang,Feizhou Chen,Min Zhang,Zhengwen Liu,Erik Jeppesen +9 more
TL;DR: The abundant small fish species were dominant in the authors' subtropical study lakes even in terms of biomass, and, accordingly, it is recommended that more attention be paid to the population dynamics of these species in the future.

Density-dependent effects of omnivorous bitterling (Acheilognathus macropterus) on nutrient and plankton communities: implications for lake management and restoration
Jinlei Yu,Manli Xia,Wei Zhen,Ruijie Shen,Hu He,Baohua Guan,James J. Elser,Zhengwen Liu,Zhengwen Liu +8 more
TL;DR: This study indicates that A. macropterus can negatively affect water quality and facilitate the dominance of cyanobacteria, therefore, monitoring and control of these small omnivorous species should be emphasized when restoring or managing shallow lakes.

Dominance of Myriophyllum spicatum in submerged macrophyte communities associated with grass carp
TL;DR: It is proposed that grazing by grass carp was responsible for the observed shift in dominance towards M. spicatum but as alternative explanations are possible, further tests by controlled experiments are needed to draw firm conclusions.

Megalobrama amblycephala grazes preferentially on Hydrilla verticillata but makes more efficient use of Vallisneria denseserrulata: implications for biological control of submerged macrophytes
Chunyu Yin,Chunyu Yin,Zhaoxia Wang,Yu Zhao,Gao Yiming,Wei Zhen,He Xiaolin,Chunsheng Yin,Baohua Guan +8 more
TL;DR: The results imply that V. denseserrulata is protected from overgrazing by the ability of M. amblycephala to make more effective metabolic use of ingested material than for H. verticillata.
