Dietary fatty acid transfer in pelagic food webs across trophic and climatic differences of Chinese lakes.

In eutrophic lake ecosystems, cyanobacteria typically lead to unbalanced phytoplankton community structure and low dietary quality for consumers at higher trophic levels. However, it still remains poorly understood how zooplankton manage to respond to seasonal and spatial differences in lake trophic gradients and temperature factors to retain highly required dietary nutrients from phytoplankton. In this field study, we investigated seston and different size classes of zooplankton of temperate and subtropical large lakes of different trophic conditions in China.

Rapid in situ assessment of high-resolution spatial and temporal distribution of cyanobacterial blooms using fishery echosounder.

Cyanobacterial blooms are increasing in frequency, magnitude, and duration globally because of enhanced eutrophication and climate change. Thus, comprehensive investigation and systematic monitoring of the spatial and temporal distribution of cyanobacteria in aquatic environments are urgently needed to better understand bloom development and complex interactions within a dynamic environment. Various methods have been used to investigate the distribution of cyanobacteria, however, none of them can provide high-resolution data for the three-dimensional spatial structure of the bloom and its dynamics in real time.

Age, growth, mortality and recruitment of thin sharpbelly Günther, 1873 in three shallow lakes along the middle and lower reaches of the Yangtze River basin, China.

Despite being the most dominant and widespread small fish species in the lakes along the middle and lower reaches of the Yangtze River basin, has been paid little attention by fisheries scientists and little is known about its population characteristics. For this reason, we estimated age, growth, mortality and recruitment of this species based on three shallow lakes, Biandantang Lake, Shengjin Lake and Kuilei Lake (BDT, SJH and KLH, respectively) in this region. A total of 13,585 (8,818 in BDT, 2,207 in SJH and 2,560 in KLH) individuals were collected during monthly sampling from July 2016 to September 2017.

Global metabolic responses of the lenok (Brachymystax lenok) to thermal stress.

High temperature is a powerful stressor for fish living in natural and artificial environments, especially for cold water species. Understanding the impact of thermal stress on physiological processes of fish is crucial for better cultivation and fisheries management. However, the metabolic mechanism of cold water fish to thermal stress is still not completely clear.

Species-specific variations in reproductive traits of three yellow catfish species (Pelteobagrus spp.) in relation to habitats in the Three Gorges Reservoir, China.

The reproductive biology of three yellow catfish congeners was studied in the Three Gorges Reservoir of the Yangtze River, China. We compared reproductive traits among the lentic, transitional, and lotic zones. A total of 4502 individuals of the three species was collected, and the sex ratio, size at 50% maturity, spawning season, fecundity, and egg size were determined.

Paradigm changes in freshwater aquaculture practices in China: Moving towards achieving environmental integrity and sustainability.

Contribution of fisheries and aquaculture to global food security is linked to increased fish consumption. Projections indicate that an additional 30-40 million tonnes of fish will be required by 2030. China leads global aquaculture production accounting for 60% in volume and 45% in value.

Effects of Brevibacillus brevis FJAT-1501-BPA on growth performance, faecal microflora, faecal enzyme activities and blood parameters of weaned piglets.

A feeding expriment was performed to investigate the effects of dietary supplementation with Brevibacillus brevis FJAT-1501-BPA fermentation on the growth performance, faecal microflora, faecal enzyme activities and blood parameters of weaned piglets. A total of 150 weaned piglets were randomly assigned to different treatments groups, which were fed the same basic diet supplemented with 10, 1, 0.1, 0.

Maintaining economic value of ecosystem services whilst reducing environmental cost: a way to achieve freshwater restoration in China.

Freshwater fisheries are central to food security in China and this remains one of the most important priorities for the growing human population. Thus, combining ecosystem restoration with economics is pivotal in setting successful conservation in China. Here, we have developed a practical management model that combines fishery improvement with conservation.

[Relationships between spatial distribution of two dominant small-sized fishes and submerged macrophyte cover in Niushan Lake of China].

By using a set of pelagic gillnets with eight mesh sizes, an investigation was made on the spatial distribution of small fishes in submerged macrophyte habitats in a shallow macrophytic lake (Niushan Lake) in the middle reach of Yangtze River in summer, 2005. The fish composition, abundance, and size structure were examined along a biomass gradient of the most dominant submerged macrophyte Potamogeton maackianus. A total of 1124 individuals from 13 fish species were caught during the study period.

[Species composition, diversity and density of small fishes in two different habitats in Niushan Lake].

This paper studied the spatial distribution of small fishes in a shallow macrophytic lake, Niushan Lake in spring 2003, and its relations with habitat heterogeneity. Based on the macrophyte cover condition, distance from lake shore and water depth, two representative habitat types in the lake were selected. Habitat A was near the shore with dense submersed macrophyte, while habitat B was far from the shore with sparse submersed macrophyte.
