“…Part of the outcomes of this correlational study was supported by a suite of experiments (Zambrano and Hinojosa 1999 Field experiments -Semi-natural ponds). Further, a high food web overlap between C. carpio together with invasive Nile tilapia and crayfish acocil was detected in the Xochimilco aquatic system (Mexico City) (Zambrano et al 2010). …”

“…Cyprinus carpio was intentionally stocked in the reservoir and it is quite probable that only the physical barrier imposed by the dam is confining this species. Cyprinus carpio has a broad tolerance to different environmental factors, including eutrophication and turbidity (Zambrano et al, 1998) that characterize the downstream reaches of the Sauce Grande River. In contrast, the restriction of P. trucha in clear waters would probably also obey to the fact that this environment more closely resembles the natural habitats (low water conductivity and turbidity, low amounts of nutrients) of this species in freshwater ecosystems of Patagonia (Macchi et al, 2007).…”

Aim We evaluated the longitudinal patterns in distribution of native and non-native fish species in a hydrologically fragmented and environmentally variable lowland temperate river. Methods Four sites representing contrasting habitat and environmental conditions were sampled: a clear water reservoir, a turbid water lagoon and two river reaches with clear and turbid waters each. Environmental variables were measured in situ and in the laboratory. Fishes were sampled using trammel and beach seine nets. Results Two main environmental scenarios were identified: the upstream reaches, with colder, clearer and nutrient-oxygen poor waters (reservoir and its downstream river) and the downstream reaches, where turbidity, dissolved oxygen, water temperature, conductivity and nutrients largely increased (lagoon and its downstream river). Fourteen species with a high non-native/native (4:10) ratio were collected. Non-native species (NNS) were confined to lentic conditions, where the silverside Odontesthes bonariensis dominated. Native species (NS) better thrive in lotic conditions where the turbid scenario further favored tolerant species. Environmental conditions also seemed to influence the distribution of NNS. Fish assemblage structure considering either, all species, NNS or NS significantly differed among sampled reaches and habitat (lentic-lotic) conditions. Total fish abundance was higher in lentic reaches. Species richness and diversity were favored by the turbid scenario. Beta diversity was mostly explained by the replacement component revealing the substitution of species as the main pattern of variation. Water conductivity, nitrates and dissolved oxygen were the most important predictor variables in the best and most frequent explanatory models of fish assemblage structures. Conclusions Our results revealed that a low diversified Neotropical fish fauna is disrupted by habitat fragmentation due to the creation of artificial impoundments and the introduction of NNS. Environmental conditions further modulate the fish assemblage structure by affecting the distribution of species where tolerant species were favored by turbid, nutrient-rich waters with higher conductivity and pH.

“…The disturbance of sediments associated with benthic feeding of omnivorous fish may increase the turbidity of water [8,9] and facilitate the release of nutrients in shallow lakes [10][11][12]. Common carp (Cyprinus carpio) may cause the resuspension of sediment and nutrient release through feeding on and expelling sediment [13]. Excretion by omnivorous fish can increase nutrient concentrations and stimulate phytoplankton growth [3,9], which also leads to reduced light intensity at the sediment surface [14][15][16].…”

The presence of omnivorous fish is known to affect aquatic ecosystems, including water quality. The effect, however, depends on the species in question, and our knowledge is limited on the effect of omnivorous crucian carp (Carassius auratus), a common and often the most numerous fish species in eutrophic shallow lakes in China. We conducted a 70-day outdoor experiment in mesocosms with and without crucian carp to examine whether this species adversely affects water quality by increasing the levels of total nitrogen (TN) and total phosphorus (TP), thereby stimulating the biomass of phytoplankton and increasing water turbidity. Compared with carp-free controls, the presence of crucian carp resulted in higher TN and TP in the water column, greater phytoplankton biomass and lower periphyton biomass, measured as chlorophyll a. Total suspended solids (TSS) also increased in the presence of fish. We conclude that crucian carp can increase TN and TP, enhance phytoplankton biomass, and increase water turbidity, thereby contributing significantly to the deterioration of the water quality. In addition to controlling external nutrient loading, the removal of crucian carp may help to improve water quality in warm shallow eutrophic lakes.
