Summary: Fish community manipulation plays a crucial role in restoring submerged aquatic vegetation in shallow lakes of the middle and lower Yangtze River Basin. In-situ fish exclusion experiments and large-scale lake manipulations demonstrated that removal of benthivorous and herbivorous fish can significantly increase SAV coverage and biomass, as well as improve water quality. This study highlights the importance of considering fish community manipulation alongside nutrient reduction when restoring SAV in shallow lakes.

Summary: The discharge of wastewaters harmed the recreational value of Lake Vesijarvi, but various measures were taken to mitigate this. The diversion of wastewaters reduced phosphorus concentration and intensive fish removal proved to be more successful in reducing cyanobacterial blooms. Later attempts at oxygenation and larger-scale intervention did not have the same positive impact and were eventually abandoned. The evaluation of fish removal intensity for maintaining the lake's current state is still ongoing.

Summary: Degradation of lake ecosystem is a common issue worldwide, and it is crucial to remediate degraded lakes to ensure water safety and ecosystem health. Restoring submerged macrophyte has been recognized as an important measure, but its contribution to overall ecological remediation is limited. Fish manipulation, which can improve water quality and promote submerged macrophyte restoration, is often overlooked in ecological remediation projects. Future studies should focus on understanding the role of fish in lake nutrient cycle and their impact on submerged macrophyte, in order to guide fish manipulation for effective remediation of shallow lakes. It is suggested that fish manipulation measures should be considered in more ecological remediation projects globally.

Summary: This study investigates the drivers of water column light attenuation (K-d) in Lake Fil, Denmark, after its re-establishment in 2012. The findings show that higher wind speed increases K-d on the same day and the next day, with significant influence from wind direction. The fast variations in K-d highlight the importance of wind on the light climate and subsequent biological elements in shallow lakes.

Summary: Longhu Lake in southeast China, a shallow eutrophic lake under biomanipulation for around 20 years, exhibits a typical bimodal structure in plankton size spectra, with relatively smaller size classes and low biomass of crustacean zooplankton. Seasonal fluctuations in size spectra are influenced by water temperature (positively) and nutrients (negatively), but the patterns and coefficients of determination remain consistent across seasons, indicating a stable plankton community in this long-term managed eutrophic lake.

Summary: A study found that the Sediment-Inferred lake-water Total Phosphorous (SI-TP) mass balance model can successfully reconstruct long-term mean lake-water total phosphorus (TP) concentrations in lakes with dominant external phosphorus supply. However, its applicability in lakes with high internal phosphorus loading, where sediment diagenesis degrades the sediment phosphorus record, has not been demonstrated. The study tested the SI-TP model in Lake Sobygaard in Denmark, which has high internal P loading, and observed sediment degradation. The resulting SI-TP record was similar to the monitored TP values, indicating the model's potential for wider application in lakes with high internal P loading.

Summary: Eutrophication and salinization interact to negatively affect freshwater ecosystems. In a study of eight lakes in Southwest China, we found that phytoplankton dynamics were more pronounced in shallow lakes and peaked in the warm season. Total nitrogen and total phosphorus were positively correlated with species number, density, and biomass, but this correlation weakened at high TP and low N:P ratio, indicating nitrogen limitation. Salinity showed a unimodal relationship with phytoplankton characteristics, peaking at 400-1000 mu S/cm (Cond). Different dominant taxa (cyanobacteria and chlorophyta) responded differently to nitrogen and salinity, with chlorophyta dominating at low TN and cyanobacteria dominating at high TN and Cond.

Summary: Eutrophication and global warming accelerate the growth of cyanobacterial blooms and the spread of invasive cyanobacterial species. This study found that phosphorus deficiency inhibits the growth of C. ovalisporum, while multiple pulses of phosphorus promote its growth and phosphorus absorption. Additionally, C. ovalisporum secretes more exopolysaccharides and alkaline phosphatase under phosphorus deficiency. These findings provide new insights into the outbreak and dispersal strategies of C. ovalisporum.

Summary: Fish community structure in shallow lakes is influenced by macrophyte cover, which provides important habitats and food sources. This study examined the relationships between fish and macrophytes at both lake and point scales in 88 Danish shallow lakes. The results showed negative relationships between macrophyte cover and fish abundance and biomass, with stronger effects at the point scale. Chlorophyll a, a measure of primary productivity, was positively related to fish abundance, except for certain fish species. The findings highlight the complex interactions between fish and macrophytes, which are influenced by lake characteristics.

Summary: Freshwater ecosystems have suffered from a significant decrease in biodiversity due to eutrophication and habitat loss. However, by re-establishing ecosystems or creating new lakes, nutrients removal, biodiversity, and recreation can be improved. Through the use of structural equation modeling, the impact of environmental variables and landscape features on fish species richness and composition in new and natural lakes in Denmark was investigated. Fish species richness is influenced by basin elevation, lake area, and salinity at the basin outlet.

Summary: Climate change and urbanization have complex interactions with phytoplankton blooms (PBs) in Lake Dianchi. Our study found that PBs in the lake had advanced initiation and longer duration, likely due to increased water temperature and reduced nutrient concentrations. However, the area and severity of PBs showed a decreasing trend, possibly attributed to increased wind speed and/or reduced nutrient levels. Urbanization, with the enhanced land surface temperature, could alter the thermodynamic characteristics and regulate the phenology and severity of PBs in the lake.

Summary: With the retreat of glaciers, new ponds and lakes are formed, which become more productive as vegetation develops. Our study in West Greenland found that older lakes had higher nutrient concentrations and organic matter content, as well as higher biomass and richness of certain aquatic organisms. The food web in the older lakes was more complex, with a longer food chain and higher taxonomic diversity, suggesting a succession process following glacial retreat.

Summary: In temperate shallow lakes, submerged macrophytes enhance zooplankton grazing and maintain a clear-water state. However, the role of macrophytes for zooplankton and their grazing potential in tropical lakes remains unclear. Our study in a tropical lake in China found that the dominance of copepods differed between basins, with cyclopoids dominating in the algal basin and calanoids in the macrophyte basins. The biomass ratios of calanoid:copepod and zooplankton:phytoplankton were higher in the macrophyte basins. Our results suggest that restoration measures involving macrophyte transplantation and fish removal can reduce fish predation and maintain clear-water state in tropical lakes, although top-down control may be weaker compared to temperate lakes.

Summary: Salinization of freshwater ecosystems caused by climate change and water abstraction for agriculture is a major challenge. Understanding how aquatic ecosystems respond to salinization is crucial for climate change adaptation, especially in arid areas. Experimental mesocosm facilities were established in Turkey to examine the effects of salinization and climate change on shallow lake ecosystems. The experiments showed that salinization, modulated by climate, significantly impacted the structure and function of lake ecosystems. The design of the mesocosm facilities, basic results, and recommendations for conducting mesocosm experiments under saline/hypersaline conditions are presented.

Summary: Sustainable management of lakes requires addressing ecological, economic, and social challenges, with a focus on achieving ecological improvement in a co-beneficial context. In-lake restoration measures can bring rapid ecosystem responses, especially when combined with circular economy practices. However, lake restoration approaches need to be carefully assessed to ensure they effectively address lake-specific problems, are cost-effective, and promote valuable ecosystem services.
