Abstract Brazil is a megadiverse country and participant of fundamental environmental agreements for biodiversity conservation. However, the internal politics cultures that affect negatively ecological integrity in Brazilian freshwater need to be improved on condition sustainable management. Scientific community, government stakeholders are constant conflicts goals. Meanwhile, current model aquaculture shows problems impact due lack appropriated planning legislation aquatic biota. The...
Reanalysis data have proven to be a valuable support for hydrologic modeling and calculation of standardized climate indices, useful tools characterizing local regimes improving water resource management in areas with limited availability observational data.This study examines the use ERA5 dataset emphasizing bias correction techniques enhance their applicability understanding limits case Georgia. The work assesses effectiveness five - Linear Scaling (LS), Empirical Quantile Mapping...
This work describes the length–weight relationship (LWR) of 37 fish species from Taquari River, one tributaries Jurumirim Reservoir in high Paranapanema Basin, São Paulo, Brazil. Information was not yet available FishBase on LWRs 22 and maximum weights (Wt) 24 species. New standard lengths are presented for nine as well two
The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for fishes. Our NEOTROPICAL FRESHWATER FISHES data set is to produce a large-scale inventory, covering entire from Mexico and Caribbean in north southern limits Argentina, Paraguay, Chile, Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, represented by occurrence abundance data. number of species numerous orders are as follows: Characiformes...
Knowledge of ichthyoplankton dynamics is extremely important for conservation management as it can provide information about preferential spawning sites, reproductive period, migratory routes and recruitment success, which be used to guide efforts. However, identification the eggs larvae Neotropical freshwater fish a difficult task. DNA barcodes have emerged an alternative highly accurate approach species identification, but barcoding time-consuming costly. To solve this problem, we aimed...
Abstract River damming alters the physical–chemical variables of water and often causes compartmentalisation aquatic habitats. Seasonality can add complexity to longitudinal compartmentalisation. The spatial temporal effects these two phenomena on structure ichthyofauna from a tributary under influence were evaluated, based following hypotheses: (1) transition habitats have greatest species richness; (2) community similarity decreases with increasing distance between sites; (3) conservation...
AIM: The aim of the present study was to evaluate diet and biological attributes population Apareiodon affinis residing near net-cage fish farming activities in Chavantes reservoir. METHODS: Samples were collected from two populations: one net cages (NC) an area not influenced by these denominated "reference site" (RS). Monthly sampling carried out Mar/2008 Feb/2009. Fish caught with a standardized effort using gill nets deployed for 14 hours. After all individuals measured (standard length)...
Abstract The aim of this study was to report the occurrence Austrodiplostomum compactum metacercariae in eyes 98 specimens loricariid fish ( Hypostomus ancistroides , H. hermanni iheringii margaritifer regani strigaticeps sp. and Megalancistrus parananus ) from Chavantes reservoir (23°07′36″S 49°37′35″W) located rio Paranapanema, upper Paraná river basin, municipality Ipaussu, São Paulo State, Brazil. Fish were collected October 2007 February 2009 using nylon monofilament gill nets...
Here the length–weight relationships (LWR, hereafter) of Pareiorhina pelicicei, Trichomycterus candidus, T. pirabitira, and piratymbara are provided. Samples each species were collected between April July 2017 with a hand net (1.5 mm mesh) in three sites from upper Paraná River basin, Southeastern Brazil. These results increase knowledge about LWR Neotropical freshwater fish.
This study describes the invasion of upper Paraná River basin by Pterygoplichthys ambrosettii based on a literature review and field samples. has been reported in 42 localities throughout basin, including Tietê, Paranapanema, Paraná, Grande Aguapeí rivers. The ascent P. after inundation Sete Quedas Falls release individuals aquarium hobbyists were primary drivers this invasion.
Abstract: Aim Investigating whether wild fish accept residual ration from cage farming to the point of changing their diet and fish-food interaction network. Methods The species, Astyanax lacustris, Iheringichthys labrosus, Leporinus amblyrhynchus, Schizodon nasutus Steindachnerina insculpta, bred in Chavantes Reservoir, Upper Paraná basin, was evaluated. Samples were collected on a monthly basis - March 2008 February 2009 around (NC) reference site (RS) free influence activity. Results...

Length–weight relationships (LWRs) for 35 freshwater fish species from the SP/RJ coastal basin in Brazil are presented this paper. Fishes were captured between 2011 and 2015 on an irregular basis using electrofishing, sieves, trawl nets, cast nets fish-traps. In study new LWRs reported 28 species, plus total weight length 34 nine respectively. The provides information less-studied can serve as a management conservation area.
The present study provides length-weight (LWR) and total length-standard length (LLR) relationships for 16 freshwater fish species collected in coastal rivers of the northern Brazilian, state Amapá 2015. Fishes were caught heterogenic environments like ponds, stream river channel with sieve trawl. As result, we novel information LWR LLR 11 15 species, respectively. Maximum values (first or new maximum values) TL, SL WT are presented 14, 12
The study presents length–weight relationships (LWR) and length–length (LLR) for 23 fish species captured in the Porto Primavera Reservoir, Upper Paraná River. Seventeen of LWRs 20 LLRs are reported first time. New maximum standard lengths presented 17 as well weights three new total weight records 19 species.
This paper presents length–weight relationships (LWR) for 11 freshwater fish species from the Sapucaí-Mirim River, a tributary of Grande River basin, São Paulo, Brazil. The specimens were captured in quarterly samplings between March 2011 and December 2014, using gillnets mesh size: 1.5–9.0 cm knots. present study adds new information maximum length seven species, LWR records four species.
ABSTRACT Dams are considered an important source of modification upon the structure aquatic communities and their reflexes diverse on fish fauna. Although there several hydroelectric power plants in Brazil, long-term effects feeding activity ichthyofauna unknown. Thus, this study aimed to investigate old reservoir (fifty years) trophic dynamics The diet 20 species was analyzed, identifying 37 food items belonging six categories, which enable create groups. results found here suggests that...
Abstract In this study, the inverted trophic hypothesis was tested in freshwater fish communities of a reservoir. The distribution species three habitats Jurumirim Reservoir, Brazil, examined using both richness and relative proportions different groups. These groups were used as proxy for functional structure an attempt to test ability these measures assess diversity. Assemblage structures first described non‐metric multidimensional scaling (NMDS). influence environmental conditions...
