“…Visual-feeding fish are size-selective predators, selectively feeding on large zooplankton (Durbin 1979;O'Brien 1979). The addition of size-selective fish predators to fishless communities not only suppresses the larger zooplankton, but alters nutrient levels and increases phytoplankton standing crops (Hurlbert et al 1972;Shapiro et al 1975;Andersson et al 1978;Hurlbert and Mulla 1981;Lynch and Shapiro 198 1). While visual-feeding fish such as the bluegill (Lepomis macrochirus) may ingest filamentous algae, the algae function only as a supplemental food source during periods of low invertebrate prey abundance (Kitchell and Windell 1970).…”

The ingestion rates of filter-feeding gizzard shad for different sizes of suspended particles were measured using mixtures of microspheres and zooplankton. Ingestion rate increases as a function of particle size, leveling off at 60 pm. The particle-size-dependent ingestion rates were consistent with a model of filtering efficiency based on the cumulative frequency of interraker distances of gizzard shad gill rakers.Comparison of ponds containing gizzard shad with control ponds without fish showed that gizzard shad suppressed Ceratium, the only phytoplankton species large enough to be ingested at a maximum rate. Gizzard shad did not have a significant effect on populations of Synedra, Peridinium, Navicula, Kirchneriella, Cyclotella, and Chlamydomonas. Populations of Ankistrodesmus, Cryptomonas, Cosmarium, Rhodomonas, and algae and bacteria from 2-4 pm were enhanced by gizzard shad.

“…One such approach is to reduce the abundance of planktivorous fish in a lake to allow an increase in the size and grazing pressure of herbivorous zooplankters, with a consequent reduction in the abundance of algae. Indeed, such effects have been commonly observed when planktivore populations have been reduced by natural causes, such as winter-kill (Schindler & Comita, 1972;Brashier, Churchill & Leidahl, 1973), or by artificial means, such as fish toxins (Hrbacek et ai, 1961;Andersson et al, 1978;Stenson et al, 1978;Fott, Pechar & Prazakova, 1979). However, the intentional use of this approach has been tested only in small shallow ponds (Lynch & Shapiro, 1980;Leah, Moss& Forrest, 1980), with the exception of the work of Stenson et al (1978) in which a lake was kept free of fish for several years.…”

SUMMARY. 1. Rotenone was applied to Round Lake in the autumn of 1980 in order to eliminate predominantly planktivorous and benthivorous fish. The lake was subsequently restocked with a higher population density of piscivores. The effect of this biomanipulation on the phytoplankton and zooplankton communities and on total nutrient concentrations was monitored at fortnightly intervals during the summers, from May 1980 to September 1982. 2. The abundance of phytoplankton was much lower after biomanipulation and was consistent with observed changes in Secchi disc transparency, total attenuation coefficient and chlorophyll a concentration. Zooplankters were also less abundant in 1981 and 1982 but the decrease in numbers was more than offset by the large increase in the mean sizes of the zooplankters present, so that the estimated grazing pressures in 1981 and 1982 were at least double the 1980 value. 3. Daphnia, rare in 1980, became the dominant genus in 1981 and 1982, and a shift to progressively larger‐bodied Daphnia species was observed. 4. Although total nitrogen and total phosphorus levels were generally lower after biomanipulation, their decline could not explain the reduction in phytoplankton abundance which was attributed to the increased grazing pressure. Possible causes of the observed declines in nutrient concentrations are discussed.

“…Larger species of herbivore zooplankton became dominant, accompanied by decline of chlorophyll a concentrations and algal densities and increasing transparency (Hrbacek et al, 1961 ;Andersson et al, 1978 ;Leah et 1980 ; Shapiro et al, 1982 ;De Bernardi et al, 1982 ;Benndorf et al, 1984 ;Shapiro & Wright, 1984). We hypothesised that decrease in algal abundance and increase in water transparency would result mainly from the sharp increase in the herbivore zooplankton populations in the absence of planktivorous fish .…”

Biomanipulation was carried out in order to improve the water quality of the small hypertrophic Lake Zwemlust (1 .5 ha ; mean depth 1 .5 m) . In March 1987 the lake was drained to facilitate the elimination of fish . Fish populations were dominated by planktivorous and benthivorous species (total stock c . 1500 kg) and were collected by seine-and electro-fishing . The lake was subsequently re-stocked with 1500 northern pike fingerlings (Esox lucius L .) and a low density of adult rudd (Scardinius erythrophthalmus). The offspring of the rudd served as food for the predator pike . Stacks of Salix twigs, roots of Nuphar lutea and plantlets of Chara globularis were brought in as refuge and spawning grounds for the pike, as well as shelter for the zooplankton .The impact of this biomanipulation on the light penetration, phytoplankton density, macrophytes, zooplankton and fish communities and on nutrient concentrations was monitored from March 1987 onwards . This paper presents the results in the first year after biomanipulation .The abundance of phytoplankton in the first summer (1987) after this biomanipulation was very low, and consequently accompanied by increase of Secchi-disc transparency and drastic decline of chlorophyll a concentration .The submerged vegetation remained scarce, with only 5 % of the bottom covered by macrophytes at the end of the season .Zooplankters became more abundant and there was a shift from rotifers to cladocerans, comprised mainly of Daphnia and Bosmina species, the former including at least 3 species .The offspring of the stocked rudd was present in the lake from the end of August 1987 . Only 19% of the stocked pike survived the first year.Bioassays and experiments with zooplankton community grazing showed that the grazing pressure imposed by the zooplankton community was able to keep chlorophyll a concentrations and algal abundance to low levels, even in the presence of very high concentrations of inorganic N and P . The total nutrient level increased after biomanipulation, probably due to increased release from the sediment by bioturbation, the biomass of chironomids being high .At the end of 1987 Lake Zwemlust was still in an unstable stage . A new fish population dominated by piscivores, intended to control the planktivorous and benthivorous fish, and the submerged macrophytes did not yet stabilize .
