This study investigated the environmental factors influencing the distribution of the endangered arapaima (Arapaima spp.) in floodplains of the Amazon. The abundance of arapaima was found to be positively related to the area and depth of the water column, and hence volume of lakes. Greater depth of water column also was related positively with the abundance and presence of arapaima in connecting channels. The abundance of arapaima was positively related to the connectivity of the lake with… 

Human and environmental influences on the distribution and abundance of arapaima in river floodplains of the Lower Amazon

Academic) Understanding the factors influencing the abundance and distribution of tropical floodplain fishes is an important component of fisheries management plans to support future sustainable

Protection gaps in Amazon floodplains will increase with climate change: Insight from the world's largest scaled freshwater fish

1. The Amazon floodplains represent important surfaces of highly valuable ecosystems, yet they remain neglected from protected areas. Although the efficiency of the protected area network of the

Factors determining the structure of fish assemblages in Tarumã River, Jaru Biological Reserve, Machado River drainage, northern Brazil

ABSTRACT Few studies on fish assemblages and relations with environmental factors in aquatic systems in southeastern Amazonia have been carried out when compared to other areas in the Amazon.

Trophic Ecology of Arapaima sp. in a ria lake—river–floodplain transition zone of the Amazon

Comparing stomach content analysis and measurements of carbon and nitrogen stable isotope values from dorsal muscle indicated that ria lakes may provide better feeding grounds for arapaima during the dry season, presumably because ria Lakes are interconnected with a large stream network and the main river channel year round.

Seasonal dynamics of the fish assemblage in a floodplain lake at the confluence of the Negro and Amazon Rivers.

An open system with high spatial and temporal heterogeneity created by the meeting of two large rivers with different water chemistry, Lago Catalão has a dynamic fish assemblage that is dominated by seasonally transient species.

Flood pulse effects on multispecies fishery yields in the Lower Amazon

This study applied regression techniques to a hydrological and fishery record for 42 species of the Amazon River floodplains to quantify and better understand flood pulse effects on fishery yields and highlighted the complex dynamics of river-floodplain fisheries in relation to interannual variability in flood pulses.

Fishery yields vary with land cover on the Amazon River floodplain

Inland fisheries underpin food security in many tropical countries. The most productive inland fisheries in tropical and subtropical developing countries occur in large river–floodplain systems that

Community-based management induces rapid recovery of a high-value tropical freshwater fishery

It is quantified how a ‘win-win’ community-based resource management program induced stock recovery of the world’s largest scaled freshwater fish (Arapaima gigas), providing both food and income, and highlighted the need to include local stakeholders in conservation planning of Amazonian floodplains.



Lateral migration of Arapaima gigas in floodplains of the Amazon

This study deduced in detail the lateral migration –those between river channels and floodplain habitats – of the pirarucu (Arapaima gigas), a giant, obligate air-breathing species of the Amazon Basin, allowing for a conceptual model of lateral migration of floodplain fishes.

Fish community structure in relation to environmental variation in floodplain lakes of the Araguaia River, Amazon Basin

We examined the relationship between structure of fish communities and 11 environmental variables in floodplain lakes from the Middle Araguaia River, Brazil. Samples were collected at the beginning

Factors regulating diversity and abundance of fish communities in Pantanal lagoons, Brazil

Results suggest that the species select lagoons to avoid or minimize their confine- ment in inappropriate floodplain habitats, and a combination of strategies determines the diversity and abundance of the fish species in the Nhecolandia Pantanal.

Factors determining the structure of fish communities in Pantanal lagoons (MS, Brazil)

The fish communities of lagoons in the Nhecolândia Pantanal were studied to determine the factors which are responsible for the composition and abundance of species. Fishes were collected in 19

Fish assemblages of tropical floodplain lagoons: exploring the role of connectivity in a dry year

Observed patterns of variation in assemblage attributes were directly correlated with factors related to hydrological connectivity, such as depth, resources (zooplankton and chlorophyll a) and nutrients (total phosphorus).

Floodplain lake fish assemblages in the Amazon River: directions in conservation biology

The Neotropical region is renowned for its high biodiversity, and the Amazon River basin contains the highest number of fish species of any river system in the world. In recent years, habitat

Relationships between fish assemblages, macrophytes and environmental gradients in the Amazon River floodplain

Canonical correspondence analysis provided evidence that floodplain fish assemblages formed by the 76 most common species were influenced by physical variables, macrophyte coverage and habitat complexity, which jointly accounted for 67% of the variance of fish species assemblage.

Population density, growth and reproduction of arapaima in an Amazonian river‐floodplain

It is hypothesised that compliance with minimum size limits of catch during the high density (managed) situation, where there was no harvest of immature fishes, may have led to faster average body growth rate and earlier reproduction, which has greatly promoted population recovery.

Conservation strategies for Arapaima gigas (Schinz, 1822) and the Amazonian várzea ecosystem.

A spatial autocorrelation analysis of molecular data obtained for Arapaima gigas suggests that genetic exchange is significantly restricted at distances greater than 2,500 km, and recommends implementing a source-sink metapopulation management and conservation model.

General aspects of floodplain ecology with special reference to Amazonian floodplains

Floodplains are wetlands which oscillate between terrestrial and aquatic phases. This makes them alternately suitable for aquatic and terrestrial organisms, but makes utilization by humans difficult.
