“…Similarly, in Lake Chivero, Zimbabwe, smaller fish were found in the littoral zone dominated by E. crassipes in comparison to the pelagic zone (Brendonck et al, 2003). However, the above-mentioned studies did not show any evidence for an effect of invasive macrophytes on species diversity; and Slade et al (2005) and Hoyer et al (2008) found no differences in fish assemblages between invaded and native macrophyte communities.…”

“…In relatively vegetated areas, fish abundance decreased in invaded vegetation following a drop in water depth due to increased habitat complexity and decreased dissolved oxygen concentrations (Troutman et al, 2007). In contrast, other studies have shown that fish abundance did not differ between areas with or without invasive macrophytes (e.g., M. spicatum, Slade et al, 2005;H. verticillata, Hoyer et al, 2008;Phragmites austalis, Aday, 2007;Kulesza et al, 2009).…”

Effects of invasive macrophytes on freshwater fish and macroinvertebrate communities: the role of invasive plant traits

2011

Biological invasions of aquatic plants (i.e., macrophytes) are a worldwide phenomenon, and within the last 15 years researchers have started to focus on the influence of these species on aquatic communities and ecosystem dynamics. We reviewed current literature to identify how invasive macrophyte species impact fishes and macroinvertebrates, explore how these mechanisms deviate (or not) from the accepted model of plant-fish interactions, and assess how traits that enable macrophytes to invade are linked to effects on fish and macroinvertebrate communities. We found that in certain instances, invasive macrophytes increased habitat complexity, hypoxia, allelopathic chemicals, facilitation of other exotic species, and inferior food quality leading to a decrease in abundance of native fish and macroinvertebrate species. However, mechanisms underlying invasive macrophyte impacts on fish and macroinvertebrate communities (i.e., biomass production, photosynthesis, decomposition, and substrate stabilization) were not fundamentally different than those of native macrophytes. We identified three invasive traits largely responsible for negative effects on fish and macroinvertebrate communities: increased growth rate, allelopathic chemical production, and phenotypic plasticity allowing for greater adaptation to environmental conditions than native species. We suggest that information on invasive macrophytes (including invasive traits) along with environmental data could be used to create models to better predict impacts of macrophyte invasion. However, effects of invasive macrophytes on trophic dynamics are less well-known and more research is essential to define system level processes.

“…Aquatic macrophytes play an important role in structuring fish assemblages (Carpenter and Lodge 1986;Dibble et al 1996;Agostinho et al 2003;Slade et al 2005). They provide higher carrying capacity for food resources due to the availability of substrates for prey and higher productivity.…”

Influence of the macrophyte Eichhornia azurea on fish assemblage of the Upper Paraná River floodplain (Brazil)

The architecture of aquatic macrophytes adds structural complexity to the littoral region. This increased habitat heterogeneity prompts greater diversity and stability of biotic communities. However, there are few studies that explore the ecological role of macrophytes in the Neotropical region. Then, the aim of this study was to determine spatial and diel influence of near-shore Eichhornia azurea stands on fish assemblage attributes and structure, in the Upper Paraná River floodplain, considering a meso-habitat scale. To achieve this objective, fish were trapped in four stands of macrophytes, in three positions (middle and border of the stand and open area) with samplings taken at different times of the day (6 h, 12 h and 18 h). A total of 537 fish of 16 species were caught. Dissolved oxygen varied significantly among positions. Fish assemblage attributes (species richness, evenness and Shannon Diversity Index) also varied among positions. Fish assemblage structure (summarized by a detrended correspondence analysis) and size structure were strongly influenced by times of the day and positions. The patterns observed can be explained by factors such as oxygen concentration, food resource availability and predation, all influenced by macrophytes. We suggest that any strategy to manage fish diversity and fish stocks has to consider aquatic macrophytes.

“…Although the importance of subaquatic structures in determining fish assemblages has long been the subject of discussion (Noble, 1980;Crowder & Cooper, 1982;Ploskey, 1985, Carpenter & Lodge, 1986, most of the studies on this topic have been restricted to examining the role of macrophytes (Dibble et al, 1996;Miranda & Hodges, 2000;Slade et al, 2005;Agostinho et al, 2007aPadial et al, 2009) and artificial structures (Freitas & Petrere, 2001;Santos et al, 2008Santos et al, , 2011a. However, some studies have evaluated the role of fallen trunks and the impact of their removal on the biota of a given area and have also highlighted the role of submerged trunks in creating structure within habitats (Sass et al, 2006;Roth et al, 2007, Helmus & Sass, 2008Ahrenstorff et al, 2009).…”

The role of submerged trees in structuring fish assemblages in reservoirs: two case studies in South America

et al. 2011

The importance of subaquatic structures in determining fish assemblages is well documented in the literature, but few studies have examined the influence of submerged vegetation resulting from river impoundments in which arboreal vegetation was not removed. The purpose of this study was to evaluate the role of submerged trunks determining abundance and composition of fish assemblages by comparing habitats with and without them in two reservoirs of different ages. The results of this study demonstrated the importance of structured areas (with submerged vegetation) to the abundance of fish in both reservoirs. However, the role of these structures in maintaining species richness and diversity was significant only during the initial years after the impoundment. The occupation of these habitats by small invertivorous fish indicates that the nonremoval of arboreal vegetation in these reservoirs contributes to the increase of their biogenic capacity. In addition, vegetation provides shelter against predation. Considering the conservation of fishery resources, we conclude that the pre-removal of arboreal vegetation in new reservoirs should be allowed only to the extent necessary to maintain acceptable water quality, even considering transitory and localized hypoxic processes.
