This study examines the relationships between fish, environmental variables and submerged macrophytes within the irrigation system of the lower valley of the Río Colorado in southern Argentina. Using Canonical Correspondence Analysis (CCA), the strongest environmental gradients detected were conductivity and carp ( Cyprinus carpi) biomass per unit area of channel cross-section. These variables were positively associated with each other and also with water turbidity. Sites scoring high on these… 
Influence of the macrophyte Eichhornia azurea on fish assemblage of the Upper Paraná River floodplain (Brazil)
Any strategy to manage fish diversity and fish stocks has to consider aquatic macrophytes, as shown by the patterns observed, which can be explained by factors such as oxygen concentration, food resource availability and predation.
Effects of waterfowl, large fish and periphyton on the spring growth of Potamogeton pectinatus L. in Lake Mogan, Turkey
It is suggested that even if waterfowl and large fish are in high densities, their effect on fennel pondweed spring growth in lakes with abundant submerged vegetation, such as Lake Mogan, is low.
The structuring role of free-floating versus submerged plants in a subtropical shallow lake
The results suggest that bottom-up effects of free-floating plants are weak when cover is low or intermediate, and cascading effects on phytoplankton through free- floating plant impacts on piscivorous fish are unlikely to be strong.
Propagule bank and plant emergence of macrophytes in artificial channels of a temperate irrigation area in Argentina
The irrigation district of the lower valley of Río Colorado (62° 37′ W, 39° 23′ S) was examined during 1995 and 1996 to evaluate propagule bank abundance and regeneration in five irrigation and five
Dense macrophytes influence the horizontal distribution of fish in floodplain lakes
It is demonstrated that oxygen content influences fish species composition, and indicates that fish species are able to use less suitable microhabitats most likely because of morphological, physiological and behavioral adaptations.
Successful reproduction of common carp Cyprinus carpio in irrigation waterways
The successful reproduction of feral C. carpio in irrigation waterways confirms its high adaptability and plasticity of traits and its classification into the phytolithophil guild, as opposed to thephytophil wild form.
Spatiotemporal Variation in Shallow-Water Freshwater Fish Distribution and Abundance in a Large Subtropical Coastal Lagoon
Patos Lagoon is located off the southern Brazilian coast and represents one of the largest coastal lagoons in the world. We estimated hydrological and physicochemical conditions associated with
Drivers of Macrophyte Assemblage Structure in Southeast Queensland Streams
Recent drought and population growth along the east Australian coastline, combined with water quality issues and degradation of rivers of national significance, have focused attention on the
Aquatic Nuisance Species in the Great Lakes and Mississippi River Basin—A Risk Assessment in Support of GLMRIS
Risk increased over time for some aquatic nuisance species based on the time frame in which these species were considered likely to establish in the new basin, and the need to balance multiple uses of the Chicago Area Waterway System must be considered when identifying control measures to prevent aquatic nuisance Species movement between the two basins.


Macrophytes, a key to understanding changes caused by eutrophication in shallow freshwater ecosystems.
The model hypothesis suggests that periphyton development acted as a trigger for macrophyte decline, with a postponed phytoplankton reaction due to allelopathic growth limitation by substances excreted by the macrophytes, and the supposed role of allelopathy is now experimentally supported.
Effects of benthivorous bream (Abramis brama) and carp (Cyprinus carpio) on sediment resuspension and concentrations of nutrients and chlorophyll a
No relationship was found between size of fish and amount of resuspension, but the effect of bream was twice as great as that of carp, and Silicate, chlorophyll a, total P and total N were all positively correlated with fish biomass, but orthophosphate showed no correlation.
Benthic-pelagic interactions in shallow water columns: an experimentalist's perspective
Shallow water column benthic and pelagic communities are thought to be linked by trophic relationships, through life history or ontogenetic links, and by biologically or physically-mediated
