“…Based on previous studies (Jurajda, Adámek, Janač et al, 2016), the reservoir was estimated to contain ≈8000 bream of this size class, or ≈181 ind/ha. As transmitter implantation took place in late autumn, it was not possible to determine the sex of the fish (no visible signs of sexual maturity).…”

As temperatures drop and fish metabolism slows, cyprinids are generally assumed to form dense, static shoals or migrate to suitable sites up tributaries to reduce predation risk. Using telemetry, common bream Abramis brama (L.) were observed to remain active and (presumably) foraged throughout winter in an area in the middle of an 8‐m‐deep valley reservoir coinciding with a 3–5 m zone of warmer, oxygenated water below an inverse thermocline. Tagged bream appeared to avoid cold, shallow zones (<1.5 m) at the inlet and banks and the deepest zone (5–8 m) near the dam/outlet, possibly due to poor food availability. Under certain conditions, bream populations showed higher levels of winter activity (and feeding) than previously assumed, with implications for both reservoir fisheries management and future studies assessing cyprinid behaviour, energy budgets and diet in lakes and reservoirs.

“…Consequently, removal of perch juveniles, larvae and eggs may be undertaken as a biomanipulation measure, while larger perch are left behind (e.g. Jurajda et al 2016). However, what constitutes a "large piscivorous perch" differs considerably between studies, e.g.…”

“…fish. In a broader sense, biomanipulation efforts also tend to focus on reducing benthivorous fish in addition to planktonophagous species (Jurajda et al 2016), whose feeding habits may support eutrophication processes in reservoirs through bioturbation (Adámek & Maršálek 2013). In the Czech Republic, there are a number of ongoing biomanipulation projects aimed at improving water quality in drinking water reservoirs through ecological measures rather than through chemical intervention.…”

“…Successful biomanipulation studies involving biological agents like barley straw showed cost-effective results with a small capital amount for treating eutrophic reservoirs in African provinces (Mustapha 2010). Biomanipulation experiments enhanced with ecohydrological approaches will always provide a sustainable and positive cost-bene t platform to treat water bodies over conventional methods involving costly ex-situ treatment or equipment analysis and other externalities (Jurajda et al 2016).…”

Eutrophication of water bodies and deterioration of water quality is an emerging environmental crisis. The root causes, pathways and consequences of eutrophication are multidirectional and provide a huge scope of riskanalysis and risk-assessment in the domain of remediation studies. However, a deep insight on restoration studies shows a global transitional trend of evolution of traditional restoration methods to advanced innovative techniques with pioneering development in the eld of science and technology. This study introduces a novel approach of considering ecohydrological assessment of eutrophication emphasizing classical biomanipulation practices and their evolution into innovative methods coined as 'eco-bioengineering' method. The main objective of this study is to critically analyse and recognize the research gaps in classical biomanipulations and appreciate the reproducibility and e cacy of eco-bioengineering methods at micro-and macrolevel aquatic ecosystems. Comprehensive literature review was conducted in o ine and online planforms, and our survey revealed continuation of a historical trend in classical biomanipulation practices (75.36%) and an ascending drift in eco-bioengineering research (24.64%) in the immediate decade (2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018)(2019)(2020). At a global scale, recent biomanipulation research is skewedly distributed in Europe (43.48%), East Asia (34.78%), North America (8.70%), South America (2.90%), South Africa (4.35%), Oceania (1.45%), Middle East (1.45%) and non-speci c regions (2.90%). Finally, this study revealed the comprehensiveness of eco-bioengineering methods and their strong ecological resilience to recurrence of eutrophication and uctuating environmental ows in the future. Therefore, this study reinforces eco-bioengineering methods a cost-effective green technologies that will sustainable solutions for restoration of eutrophic waters at a global scale.
