“…In fact, this ecological decline did not become so extreme from pelagic grazing alone. Frequent declines of zooplankton were observed in studies conducted by Ke et al (2009) and Lin et al (2014) when manipulated lakes were introduced with filter feeders. By not being limited to enclosures, zooplankton could maintain a relative stable quantity that was lower than the surrounding water.…”

“…Krebs (1979) figured out that fish will alternatively choose for profitable food where food resources are abundantly available. Ke et al (2009) found that both silver carp and bighead carp had a preference on grazing for zooplankton when reared at relatively low density. Nevertheless, within the confined area in our experimental mesocosm, silver carp and bighead carp at higher density were impelled to graze phytoplankton for food as zooplankton decline that mentioned above caused insufficient availabilities of preferential food.…”

“…It has great values not only for food fish but also for biological control of bloom-forming cyanobacteria in lakes, ponds and reservoirs (Ke et al, 2009). Due to fast growth rate, easy cultivation, high feed efficiency ratio and high nutritional value, commercial harvest of silver carp has steadily increased in recent years, especially in China.…”

“…Unfortunately, toxic cyanobacterial blooms occurs in these regions each year since the 1980s (Xie ). From 2004 to 2005, we examined the possibility of bio‐filtering toxic Microcystis blooms by stocking silver and bighead carp in large fish pens in Meiliang Bay of Lake Taihu (Ke, Xie, Guo, Liu & Yang ; Ke, Xie & Guo ). It was difficult to evaluate the effect of this practice on the water quality because of the free water exchange between the fish enclosure and the surrounding lake.…”

Summary A non‐classical biomanipulation experiment was carried out in Gonghu Bay of Lake Taihu in 2009. Silver and bighead carp were stocked in a large fish enclosure to control cyanobacterial blooms. Water quality, plankton abundance, and the intracellular and extracellular microcystins (MCs) in lake water were investigated monthly in 2009. The concentrations of nitrogen nutrients were significantly lower in the fish enclosure than in the surrounding lake, while phosphorus (especially total phosphorus) concentration was higher in fish enclosure. During the blooming period, Cyanophyta contributed to more than 90% of the phytoplankton in the surrounding lake, whereas it represented only 40–80% in the fish enclosure. The phytoplankton and crustacean zooplankton biomasses and the zooplankton/phytoplankton ratios were all significantly lower in the fish enclosure than in the lake. This result suggested that silver and bighead carp can effectively suppress the phytoplankton biomass with the initial stocking density of 7.5 g m−3 for silver carp and 1.1 g m−3 for bighead carp, despite a simultaneous decrease in the grazing pressure of the zooplankton on the phytoplankton. During the blooming period, the intracellular and extracellular MCs in the fish enclosure were reduced by 93.8% and 69.8% compared with the surrounding lake. MCs content varied from 0.34 to 18.8 ng (mean 4.8 ng) MC‐LReqg−1 wet weight in the muscle sample of silver and bighead carp in the experimental enclosure, which suggested that these fish were safe to consume for human. However, the long‐term effects of MCs on aquatic ecosystem and on public health cannot be overlooked.
