Abstract Many of the most important commercial and recreational species megadiverse Brazilian freshwater fishes migrate in rivers among essential habitats during all life stages. These movements, however, have been severely blocked by hundreds hydroelectric dams reservoirs they will be even more obstructed due to new developments. Fishways used many countries allow fish pass around dams. Fishway construction is booming Brazil, but poor understanding migrations has led legislators,...
Abstract It is difficult for agencies to evaluate the impacts of many planned dams on São Francisco River, Brazil, migratory fishes because fish migrations are poorly known. We conducted a study zulega Prochilodus argenteus , an important commercial and recreational in identify spawning areas determine linear home range. During two seasons (2001–2003), we radio‐tagged three main‐stem reaches downstream Três Marias Dam (TMD), located at river kilometer (rkm) 2,109. tagged 10 (TM), which 5 km...
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...
Pseudopimelodidae comprises 49 species of freshwater catfish endemic to South America, with limited research on their acoustic behaviour. This study focuses the pacamã Lophiosilurus alexandri Steindachner, 1876, a vulnerable São Francisco River basin, known for its ecological and economic importance. Sound production by this was analysed first time. Three individuals were recorded while being held underwater revealing two distinct sound types (type I type II) associated pectoral fin...

Abstract – Upstream fish passage was evaluated during 12 months in the vertical‐slot Igarapava Fish Ladder constructed around Dam, heavily dammed Grande River, Southeast Brazil. A video monitoring system used to observe 61,621 that passed ladder, of which 93.5% were identified 15 taxa. Among migratory species, most abundant Pimelodus maculatus (33.6% all fish), Leporinus octofasciatus (31.4%), friderici (4.5%), and Prochilodus lineatus (3.1%). Seven taxa classified as nonmigratory, these...
Abstract Serrasalmid fishes form a highly specialized group of biters that show large trophic diversity, ranging from pacus able to crush seeds piranhas capable cutting flesh. Their oral jaw system has been hypothesized be forceful, but variation in bite performance and morphology with respect diet not previously investigated. We tested whether herbivorous species have higher forces, larger muscles more robust jaws than carnivorous species. measured vivo theoretical forces 27 serrasalmid...
In the Rio Doce basin of southeastern Brazil, freshwater fish Hoplias malabaricus (trahira) is a widespread predatory characin and one few resilient native fishes in highly impacted lake system. order to test for genetic differentiation populations within this biogeographic relationships among species other basins, study was conducted using RAPD-PCR analysis samples (N = 63) phylogeographic analyses with mitochondrial DNA (mtDNA) haplotypes, including Grande Macacu river basins. basin,...
Turbine dewatering and stop/startup may lead to the death of tons fish at Brazilian power dams. The Três Marias Dam (TMD) on São Francisco River has adopted two techniques reduce quantity fish, mostly mandi (Pimelodus maculatus, Pimelodidae), affected by these maneuvers. They are: (i) spill before turbine attract out tailrace, (ii) screens in stop log slots during prevent from entering draft tube. Here, we investigated whether reduced TMD. We also determined biomass trapped be predicted...
Abstract Hypostomus is the most diverse genus within Loricariidae. These catfish species exhibit a very conservative morphology with relatively few external characteristics that differ between different species. In consequence, there challenge to understand distinction of this genus. This study aims describe sounds produced by ten from Araguari River and Paraopeba (Minas Gerais, Brazil), examine whether acoustic features could be used distinguish species, corresponding sound production...
The genus Pygocentrus contains three valid piranha species (P. cariba, P. nattereri and piraya) that are allopatric in tropical subtropical freshwater environments of South America. This study uses acoustic features to differentiate the species. Sounds were recorded two populations (red- yellow-bellied) piraya; providing sound description for first time cariba piraya. Calls distinct from all other studied populations. Red- yellow-bellied calls different each but similar those These...
Jaú, Zungaro jahu (Ihering, 1898), a large migratory catfish endemic to the rio da Prata basin, has fragile conservation status and its ecology is poorly known. We radio-tracked female jaú with total length of 1.5 m that was passed upstream Funil Dam, Grande, describe movements, habitat use, linear home range, diel activity. To track fish, we made five tracking trips in period from April, 2003 January, 2004. In addition main body Reservoir, fish also used reservoir-river transition zone...
Abstract Highly productive floodplain rivers in Brazil and elsewhere provide livelihood recreational fishing for millions of people around the world, but damming controlled water discharge are a threat to these valuable ecosystems. Supplemental releases (SWRs) at dam increasingly used restoring fisheries productivity many rivers. We proposed conceptual model hypothetical release enhance using Três Marias Reservoir (TMR) on São Francisco River (SFR), Brazil. The information needed by follows:...

Dict changes of the trahira Hoplias malabariCIIs (Bloch) (Erythrinidac, Characiformes) due to piscivorous introductions in Rio Doce valley lakes.Two pisei vorous fishes , peacock bass (CicMa /IIo//Owlus Spix & Agassi z, 1831 ) (Perciformes) and piranha (Pygocenlrus Ilauereri Kner, 1860) (Characiformes), were introduced some lakes (19°50 ' S, 42°40' W) for sport fisheries enhancement.As a consequence, small individuais species practically vanished host lakes.In this study, effects on diet ofa...
Abstract Serrasalmus marginatus is a piranha species native from the lower Paraná River basin and has been invasive in upper since 1980s. In piranhas, sounds of different have features. The aim this study was to investigate if produced by could be used distinguish two morphotypes: red‐ yellow‐eyed S. Araguari (upper basin). All temporal frequency features were equivalent both groups eye colour; it corresponds species‐specific signature described for . Nonetheless, amplitude all statistically...
