Non-native species are a major driver of biodiversity loss. Aquaculture activities play key role in introductions, including the escape fishes from fish farm facilities. Here, impact flooding due to El Niño rains 2015/2016 Lower and Middle Paranapanema River basin, southern Brazil, was investigated by evaluating escapes 12 farms. The resulted approximately 1.14 million into river, encompassing 21 three hybrids. were most abundant escapees, especially Oreochromisniloticus (Linnaeus, 1758)...
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...
Abstract: The Paranapanema River is an important, extensively explored tributary of the Upper Paraná basin. fish fauna has been investigated since 1990s; however, no study characterized richness species throughout basin, including main channel river, marginal lagoons, its tributaries, and sub-tributaries. Thus, we performed a review with 90 independent studies conducted at upper, middle, lower sections We recorded 225 species, which 165 were native, 60 non-native. found that 77% within basin...

The aim of this study is to report the presence a three non-native hybrid long-whiskered catfishes (family Pimelodidae) in Upper Paraná River basin, Brazil. Genetic analyses demonstrated that presumptive hybrids were result crossbreeding Pseudoplatystoma reticulatum (central Amazonas basin and Lower River) Leiarius marmoratus (Amazonas, Essequibo Orinoco rivers), producing commonly known Brazil as cachandiá. potential threat biodiversity, due possible genetic contamination, competition...
Abstract. Garcia DAZ, Vidotto-Magnoni AP, Costa ADA, Casimiro ACR, Jarduli LR, Ferraz JD, De Almeida FS, Orsi ML. 2019. Importance of the Congonhas River for conservation fish fauna Upper Paraná basin, Brazil. Biodiversitas 20: 474-481. The basin is among most fragmented watersheds in world. belongs to this drainage system, which has its mouth Capivara Reservoir and can be considered largest tributary free-from-dam, becoming important maintenance species richness. In order know more about...
The aim of this work was to determine the reproductive tactic population Moenkhausia intermedia , inhabiting Capivara Reservoir, lower Paranapanema River. Four different stretches reservoir were selected, and sampling carried out quarterly, in period from 2001 2004. Fish captured utilizing gill nets, cast seine nets. Later, fish identified measured had their sex identified. Here we describe proportion, standard length at first maturation (), site spawning, fecundity type spawning. showed an...
Myocastor coypus is a large semi-aquatic rodent ranked as one of the 100 most invasive species in world. In Brazil, few ecological studies have been proposed to understand relationship this with environment. To date, drivers that facilitate its establishment new areas remain unknown. However, it generally accepted natural distribution limited far southern Brazil. The present study aimed geographic M. and indicate greater risk based on bioclimatic predictors surveillance map. We observed...
Brazil has one of the most significant diversity freshwater fish in world, and this drives trade fishing tourism. Several species sport have characteristics behaviors that favor tourism its related activities. Live baits are widely used fisheries across country, at end fisheries, is common anglers may release remaining bait rivers, lakes or reservoirs. Here we report for first time crab Dilocarcinus pagei Paranapanema River basin, list were introduced similarly. During field samplings...
The combination of highly equipped smartphones, with the increased use social media, has offered a wide database. Given this, citizen science can be used to record and monitor non-native fish fauna, target new samples collaborate monitoring occurrences in areas. We aimed demonstrate efficiency media as tool cooperate studies species. Consequently, we determined occurrence points S. brasiliensis Iguaçu River basin, indicating sites greatest analyzing impact invasion on native fauna basin....
The aging process of reservoirs has been extensively investigated; however, little is known about how fish populations are adjusted after many years impoundment. Thus, this study aimed to compare the diet, length-weight relationship, sizes classes, variation in size, and age Astyanax lacustris Lütken, 1875 collected from lotic lentic habitats an reservoir. group consisted 730 captured fishes. We found that specimens had a wider range size classes (1.0 12.0 cm), were linked high frequency...
Abstract We evaluated the fish composition and ecological attributes of ichthyofauna collected in a limnological zone Taquaruçu Reservoir, lower Paranapanema River. Information about community was updated when compared to previous study (2006). Non-metric multidimensional scaling (NMDS) showed differences species between periods weighted means (CWMs) exhibited changes functional over time. Four indices were used principal coordinate analysis (PcoA) measure space species, whereas β-diversity...
Fish introductions are common practices due to intentionally or unintentionally translocations of species between watersheds. Herein we report the spread non-native cichlid Laetacara araguaiae Ottoni & Costa 2009 in Paranapanema River basin, southern Brazil. Native from Araguaia (Central Brazil), this was probably introduced by releases made aquarists. Its new area occurrence is characterized as natural nursery and important for life cycle native fish. Due its biological characteristics,...
RESUMO: O aquarismo é um hobby difundido mundialmente, com registros desde as civilizações antigas. No Brasil, a prática tem aumentado seu prestígio e representatividade. Dentre modalidades do de água doce, o "jumbo" se tornado popular, sua gerado ampla divulgação via Internet . A modalidade caracteriza pela escolha espécies peixes médio grande porte comportamento agressivo predatório, que representa ameaça aos ambientes naturais principalmente como consequência descarte inadequado das...
