“…Carp may damage the macrophytes by disrupting bottom sediment (Sidorkewicj et al 1999;Miller and Crowl 2006) and indirectly contribute to the elimination of large-bodied grazers as well, since high turbidity interferes with their foraging on algae (Kirk 1991). Resuspension of sediment and algae reduces penetration of light under the water and its availability for submergent vegetation (Hellström 1991;Sidorkewicj et al 1999). These effects may be stronger in the presence of larger carp, which are capable of penetrating deeper in a substratum than smaller fish (Panek 1987), and more intense in summer when carp take mainly benthic prey.…”

Sustainable development of common carp Cyprinus carpio pond fisheries in Europe postulates their multifunctional use, integrating exploitation of aquaculture resources with recreational services and maintenance of high levels of local biodiversity. Age classes of farmed carp are grown separately and pond ecosystems may be differently affected by different ontogenetic stages of fish. To examine these relationships, a study was conducted on spring and summer diet of carp, invertebrate abundance and community structure, and water quality characteristics in ponds stocked with three carp age classes in SE Poland. With the exception of young-of-the-year fish in spring, benthic dipterans prevailed in the diets of all carp age classes and their consumption increased from spring to summer. Zooplankton featured in the diet of carp only in spring. Medium-and large-sized cladocerans predominated among microcrustaceans found in the guts of one-and two-yearold carp. Consequently, in summer, total biomass of medium-and large-sized cladoceran grazers was substantially lower in ponds stocked with older-age fish than in ponds used for production of 1-summer-old fingerlings. The relatively sparse submerged vegetation cover and low water transparency in ponds with older fish stocks compared to ponds with youngof-the-year carp indicate a transition to a turbid water state mediated by a trophic cascade mechanism in the presence of older-age fish. Densities of water-column macroinvertebrates decreased with the age of carp in the ponds. These results suggest that non-aquaculture use of carp ponds should be diversified according to their environmental quality. Fingerling rearing ponds are more suitable for environmentally friendly multifunctional use than ponds with older stocks.

“…ponds, the only submerged macrophyte was sago pondweed (Stuckenia pectinata (L.) Börner, 1912) (Nieoczym & Kloskowski, 2015), an important foraging resource for coots (Allouche & Tamisier, 1984;Van Wijk, 1988;Hilt, 2006). Notably, carp have been reported to impair the growth of sago pondweed under experimental conditions through herbivory, increased water turbidity and stimulation of periphytic cover shading the macrophytes (Sidorkewicj et al, 1996(Sidorkewicj et al, , 1999; but see Lougheed et al, 1998;Miller & Provenza, 2007). In our study system, coot breeding densities were related to both water transparency and abundance of submerged vegetation; these two habitat variables are considerably interdependent (e.g.…”

Fish may influence habitat selection and reproductive success in waterfowl. We investigated the effects of common carp Cyprinus carpio on breeding coots Fulica atra along a gradient of fish size structure and density, created by separate stocking of age cohorts in ponds in eastern Poland. Coot breeding densities were higher on ponds with low biomass of small-sized, young-of-the-year fish than on ponds with medium-or large-sized fish, stocked at high biomass densities; they also increased with increasing submerged vegetation biomass (an effect correlated with water transparency) and emergent vegetation cover. Densities of nektonic and epibenthic macroinvertebrates and of amphibian larvae were also negatively influenced by fish size/density gradient, while densities of emerging insects were not affected. However, coot breeding success per pair was similar among pond types, while positively related to submerged vegetation, indicating that either plant food abundance was more important than the overall trophic impact of fish or fledgling production was additionally limited by factors other than food. Carp may adversely affect pond habitats of waterfowl both via trophic interactions and through abiotic disturbance of ecosystem processes. In coots, however, the effects can be mitigated by maintenance of abundant emergent vegetation and of submerged macrophytes resistant to fish.

“…Primary productivity of epiphyton might exceed that of phytoplankton in plant-dominated lakes (Moss et al, 1996) and its dry biomass can be greater than that of the macrophytes (Gons, 1979). Additionally, the contribution of organic detritus and mineral particles to the periphytic matrix is considerable in shallow lakes, where fish-mediated sediment bioturbation may induce high resuspension rates (Van Dijk, 1993;Sidorkewicj et al, 1999).…”

Response of epiphytic algae to nutrient loading and fish density in a shallow lake: a mesocosm experiment

et al. 2007

Studies on the effect of eutrophication on the ecology of shallow lakes, usually pay scant attention to changes within the epiphytic algal community, though the contribution of this to the ecosystem dynamics is transcendental. In order to test the influence of nutrient loadings and fish densities in the structure of algal epiphyton in a shallow lake, an experiment was performed using in situ mesocosms. Nutrient additions were related to significant decreases in the total epiphyton biovolume and that of bacillariophyceans and zygnematophyceans, but with increases in the abundance of cyanobacteria. The different response of algal groups at the higher nutrient concentrations (increases or decreases in their abundance and/or biovolume) can be related to their ecophysiological constraints such as different resistance to toxicant ammonium accumulation. Plant-associated macroinvertebrates numbers were positively correlated with total numbers of epiphyton. The presence of planktivorous fish enhanced the abundance and biovolume of all algal groups, except cyanobacteria. Fishes enhanced the abundance of plant-associated animals and of total epiphyton. Fish indirect effects (e.g., nutrients release) and their dietary particularities were among the factors that together with nutrients influenced epiphyton growth. The role of indirect effects of fishes and the importance of their dietary particularities are stressed as key factors to understand the processes controlling epiphyton ecology and the food web structure of shallow lakes.
