“…Main part of zooplankton species composition was represented by Cyclopoida and Rotifera in 2003. Small-size zooplankton (Rotifera, copepods and especially nauplii and small Cladocera Bosmina longirostris) indicated high predation pressure by fish stock as described, e.g., by Hrbáček et al (1961), Hrbáček (1962), DeMott (1983. In 2004, higher abundances of large Cladocera (Daphnia) were registered during the most important part of the season in Fišmistr, Baštýř and Pěšák fishponds.…”

Impact of topmouth gudgeon (Pseudorasbora parva) on production of common carp (Cyprinus carpio) — question of natural food structure

et al. 2014

Four production fishponds in the Czech Republic were investigated in 2003 and 2004 during a feeding experiment on common carp (Cyprinus carpio). In 2003, topmouth gudgeon (Pseudorasbora parva) was detected in enormous amounts in all of the investigated fishponds. P. parva got into the fishponds spontaneously by water inflow from connecting channels. The objective of this paper is to describe the condition of natural food in the presence of P. parva and its subsequent effect on carp production. The estimation of the population density of P. parva achieved at least 44 kg ha −1 in 2003. In 2004, precautions against P. parva invasion were taken and its presence wasn't recorded during the season. The impact of P. parva on natural food structure was described in terms of zooplankton and zoobenthos amounts and main fish production parameters. A special focus has been taken on the density of Daphnia genus and chironomid larvae, the most preferred zooplanktonic and zoobenthic groups in feed of P. parva, respectively. In 2003, P. parva suppressed the zooplankton populations significantly, especially large cladocerans of the Daphnia genus. Influence of P. parva on zoobenthos structure and density was not detectable. Unfavorable natural food condition in 2003 caused extremely low carp production which fell to the mean value of 283 kg ha −1 and food conversion ratio reached 3.5. On the contrary, in 2004 the mean carp production and food conversion ratio attained 634 kg ha −1 and 1.6, respectively. The results described harmful competitive effect of huge populations of P. parva and its surprising economic consequences. Costs per 1 kg of growth were increased by approximately 100% in 2003 compared with results from season 2004.

“…This is the main concept of both temporal successions, described and discussed, for example, in the Plankton Ecology Group (PEG; (Sommer et al 1986(Sommer et al , 2012, and also the basis for the food web concept (Hrbácek et al 1961;Carpenter et al 1985). The predator-prey successions described have been shown repeatedly in many studies and also seen in the long-term fluctuations of the plankton community in L. Krankesjön, where the spring peak in algal biomass is rapidly grazed down by a growing cohort of herbivorous zooplankton (Fig.…”

“…Other planktivorous and benthivorous species common in Krankesjön are rudd (Scardinius erythrophtalmus (L.)), tench (Tinca tinca), bream (Abramis brama (L.)) and white bream (Blicca bjoerkna (L.)). Piscivorous fish species common in Krankesjön are perch (Perca fluviatilis) and pike (Esox lucius) (Hansson et al 2007) the food web theory (Lindeman 1942;Hairston et al 1960;Hrbácek et al 1961), by stating that top predators may indeed affect the abundance of their prey, that is, top-down control, for example:…”

A lake as a microcosm: reflections on developments in aquatic ecology

et al. 2013

In the present study, we aim at relating Forbes' remarkable paper on ''The lake as a microcosm'', published 125 years ago, to the present status of knowledge in our own research group. Hence, we relate the observations Forbes made to our own microcosm, Lake Krankesjön in southern Sweden, that has been intensively studied by several research groups for more than three decades. Specifically, we focus on the question: Have we made any significant progress or did Forbes and colleagues blaze the trail through the unknown wilderness and we are mainly paving that intellectual road? We conclude that lakes are more isolated than many other biomes, but have, indeed, many extensions, for example, input from the catchment, fishing and fish migration. We also conclude that irrespective of whether lakes should be viewed as microcosms or not, the paper by Forbes has been exceptionally influential and still is, especially since it touches upon almost all aspects of the lake ecosystem, from individual behaviour to food web interactions and environmental issues. Therefore, there is no doubt that even if 125 years have passed, Forbes' paper still is a source of inspiration and deserves to be read. Hence, although aquatic ecology has made considerable progress over the latest century, Forbes might be viewed as one of the major pioneers and visionary scientists of limnology.

“…However, several studies have shown that planktivorous fish have a significant effect on the amount of phytoplankton and on water quality through the control of the zooplankton (HRBAČEK et al, 1961;CAR-PENTER et al, 1985;CARPENTER et al, 1987;LAMMENS et al, 1990;BENNDORF, 1990;GOPHEN, 1990). With a decrease in biomass of planktivorous fish, the biomass of the crustacean plankton as well as relative abundance of cladocerans increase and in turn, phytoplankton biomass decreases.…”

The effects of fish kill and different fish stocks on the phytoplankton and zooplankton dynamics were studied in a shallow hypertrophic reservoir system. When fish stock was below 100 kg ha -1 , nutrient availability was not the main limiting factor for growth of phytoplankton. Consequently top-down forces controlled phytoplankton. In the years with high fish stock (>100 kg ha -1 ) the bottom-up forces dominated as nutrient availability was the main limiting factor for growth of phytoplankton. We can conclude that significant water quality improvement can be achieved in the reservoir system by decreasing fish stock below 100 kg ha -1 . Although clear-water phase could be stabilised temporary by macrophytes, stabilisation of good water quality requires continuous regulation of fish community.
