“…Increased zooplankton densities immediately after the flooding were likely linked to the introduction of riverine species and augmented reproduction of existing backwater zooplankton (Górski et al, 2013). Zooplankton assemblage structure was heavily influenced by riverine inputs, dominated by rotifers in terms of both density and total biomass as reported from other studies within the Illinois River (Schuyler et al, 2009;Sass et al, 2014). Increased copepod densities after spring and winter inundation events support the riverine nature of the zooplankton community at the Merwin Preserve.…”

Echoes of a flood pulse: short-term effects of record flooding of the Illinois River on floodplain lakes under ecological restoration

et al. 2017

The flood pulse drives primary productivity, biotic communities, and abiotic processes in large river systems; however, the effects of floods on restored floodplain lakes and associated wetlands are poorly understood. Record flooding of the Illinois River, Illinois, in 2013 reconnected two floodplain preserves under restoration that had been disconnected from the river by levees for[80 years. Differences in hydrological connections between sites created a natural experiment where field-based data collection could be employed to document flood effects. Levee failure and subsequent river connection at Merwin Preserve increased nutrient capture and floodwater retention, shifted microbial and invertebrate communities, increased fish species richness, spawning and nursery habitat, and stimulated production of moistsoil plant communities during summer drawdown that provided foraging habitat for spring-migrating waterfowl. However, increased hydrologic connectivity during the growing season resulted in loss of submersed vegetation and habitat for autumn-migrating waterfowl. In contrast, river water overtopped the levee at Emiquon Preserve during a 6-day event that resulted in marginal changes in the bacterial community and negligible changes in water quality and community diversity.

“…In the Illinois River ecosystem, Rotifers abundances increased after the establishment of Bighead and Silver Carp. The biomass of cladocerans and copepods declined in association with the invasion of the two carps accompanied by changes of the food web structure [2]. In the East Lake studies about 13 C incorporation compared to 12 C, confirmed preference of Microcystis than small "greens" by SC.…”

“…Bighead carp were imported from eastern China to Arkansas in the 1970s to improve water quality in aquaculture ponds and sewage treatment lagoons. The fish, which can grow to 60 or more pounds, have since spread through the Mississippi River basin, Illinois River [2] and have been collected as far north as Lake Pepin in Minnesota. Because of their large size and abundance, Bighead carp routinely out-compete native fish for food.…”

Silver Carp (SC) (Hypophthalmichthys molitrix, Valenciennes, 1844) is a worldwide common fish for aquaculture and stocking in lakes and reservoirs. The fish is distributed through rivers, aquaculture and stocking in about 90 countries around the world. SC was first introduced into Lake Kinneret in 1969 and continues onwards. Total number of stocked fingerlings (1969-2013) was 18.5 × 10 6 (average: 441 × 10 3 per year). The total catch (tons) of SC in Lake Kinneret was 3218 tons, average: 75 t/year. Studies on SC in East Lake, China, revealed that the fish was a phytoplanktivorous and percentage of consumed phytoplankton varied between 83% -91% where Microcystis was the major item. In Lake Kinneret, the effects of SC and the Cichlid, Galilee St. Peters Fish (S. galilaeus) on Plankton resources are not independent and potentially competitors. SC is also known as efficient consumer of Microcystis. It was found that environmental conditions in Lake Kinneret were optimal for reasonable growth and recruitment of this fish to commercial fishery. The SC did not reproduce in Lake Kinneret and we recommended introducing annually 600 -1000 × 10 3 fingerlings for the benefit of water quality protection and fishermen income.

Invasive silver carp may compete with unionid mussels for algae: First experimental evidence

Unionid mussels are imperilled throughout the US, where their global diversity is highest. Silver carp (Hypophthalmichthys molitrix Valenciennes in Cuvier & Valenciennes, 1844), an invasive planktivorous fish, has spread throughout Midwestern rivers and currently threatens the Great Lakes. Because silver carp remove plankton and other particles from the water column, they may compete with mussels for food resources. This would be among the first examples of a direct competitive interaction between fish and mussels. To examine the potential for competition, a 30 day tank experiment was performed with 2 year old fatmucket mussels (Lampsilis siliquoidea Barnes, 1823) and age‐1 silver carp in three treatments: fatmucket only, silver carp only and fatmucket + silver carp. All tanks were given a commercial algal‐based diet daily and dry mass of suspended particles (an estimate of available food) and NH4, NO3 and NO2 concentrations were quantified every 5 days to track food availability and changes in nutrients. Initial and final silver carp total length (mm) and mass (g), and fatmucket length (mm), height (mm) and surface area (cm2) were measured. Survival was 100% over the test duration for both species. Fatmucket grew less in the fatmucket + silver carp treatment, whereas silver carp growth was undetectable regardless of treatment. Fatmucket also exhibited increased movement in the presence of silver carp. Suspended particles did not differ among treatments. Dissolved nitrogen concentrations were higher in the silver carp treatments, suggesting that silver carp increase nutrient availability in aquatic systems. Overall, the slower growth rates observed in the fatmucket + silver carp treatment compared with the mussel‐only treatment suggest exploitative competition between invasive planktivorous silver carp and fatmucket, and this competition may contribute to additional stress on already imperilled mussels.
