“…Zhang et al [78] reported that these species exhibit the elongation of their spines in response to elevated predation by cyclops copepods and modulate the length of their spines to a shorter state when confronted with heightened predation from fish. Additionally, previous studies also documented that Brachionus exhibit notable resilience to cyanobacterial toxins and this resilience enables them to effectively exploit colonial blue-green algae and endure their blooms [79]. The capacity of Brachionus and Keratella to endure these adverse influences elucidates their positioning as two of the genera capable of thriving in eutrophic environments.…”

A study was conducted to evaluate zooplankton species composition, abundance, and diversity in both natural and artificial lakes with varying trophic levels and to determine the relationship between zooplankton community structure and lake environmental conditions. This study hypothesized that correlations exist between zooplankton community structures and environmental parameters associated with eutrophication in natural and man-made lakes. Sampling was conducted across 16 distinct freshwater lentic ecosystems in Malaysia, including natural lakes/swamps, reservoirs, constructed lakes/ponds, and old mining lakes, spanning a range of trophic levels from mesotrophic to hypereutrophic conditions. Physicochemical parameters were measured in situ, while water and zooplankton samples were collected for nutrient analyses, as well as for zooplankton identification and enumeration. Throughout this study, a total of 58 zooplankton species, consisting of 36 species of rotifers, 12 species of cladocerans, and 10 species of copepods, were recorded. The highest zooplankton density (365.7 ± 13.7 ind L−1) was recorded in constructed lakes/ponds while the lowest density was recorded in natural shallow lakes/swamps (200.5 ± 25.5 ind L−1). On the other hand, significantly higher (p < 0.05) mean species diversity was observed in natural lakes/swamps (H’ = 2.2 ± 0.0); whereas, the lowest diversity was in old mining lakes (H’ = 1.5 ± 0.1). The canonical correspondence analysis (CCA) scores indicated that Polyarthra vulgaris and Chydorus ventricosus were the discriminating species in natural shallow lakes/swamps associated with high water transparency. Meanwhile, the small-sized cladocerans (Ceriodaphnia cornuta) and rotifers (Keratella spp., Brachionus spp., and Trichocerca spp.) were the most discriminating species in lakes with high turbidity, nutrients, and chlorophyll a concentrations, which are the main features of reservoirs and constructed lakes/ponds. Low density and diversity in old mining lakes were due to a low species number and the dominance of two species, Lophocharis curvata (38.8%) and Ptygura libera (39.7%). Overall, the high dominance of a specific zooplankton species resulted in lower biodiversity in artificial ecosystems compared to natural ecosystems. This study elucidated that zooplankton community structure in lakes was significantly influenced by the environmental conditions related to the lake trophic status.

“…49 Variation may occur due to stochastic changes in hydrodynamics. 50 Daphnia, despite their ability to create periods of clear water, are mostly unable to feed on bloom-forming colonial or filamentous cyanobacteria, 51 as the size of the particles the daphnids filter is limited. [52][53][54] The lifespan of Daphnia is very short, and its seasonal succession is rapid.…”

Cyanobacterial blooms, occurring frequently in eutrophic freshwaters worldwide, are considered as potential hazards to ecosystems and human health, and it is often difficult and expensive to control their outbreaks in large lakes through reduction of nutrient loadings. Biomanipulation, launched as an ecology-based solution in the 1970s, was once believed to be an effective way to counteract cyanobacterial blooms. It is divided into traditional biomanipulation (TB) and nontraditional biomanipulation (NTB) that use filter-feeding Daphnia and filter-feeding fish, respectively. There have been numerous reviews on the former, yet few on the latter. Here, we first revisit the debate on the digestibility of cyanobacteria in silver and bighead carp. Then, we review 42 experiments that clearly mention cyanobacterial changes and reveal substantial reductions in cyanobacterial abundance by filter-feeding carp in 88% of the cases. In particular, in a whole-lake experiment in Lake Donghu, increased stock of silver and bighead carp effectively decreased Microcystis blooms from a coverage of 87% in 2021 to 0% in 2022. Finally, we discuss possible factors related to NTB��s effectiveness that depends not only on standing stock, niche divergence and shape preference of the fish but also on trophic status of the waterbodies. Particularly, silver and bighead carp feed more effectively on colony-forming Microcystis than on filamentous cyanobacteria, but are capable of increasing small-sized algae. NTB can be used to prevent or diminish cyanobacterial blooms that are poorly grazed by Daphnia, providing an effective and sustainable in-lake ecotechnology to combat heavy cyanobacterial blooms in eutrophic waterbodies.
