O aquarismo é um hobby praticado mundialmente com aumento de popularidade no Brasil nas últimas décadas. A soltura peixes ornamentais em ambientes naturais equivocada, sendo considerada introdução espécies e crime ambiental. Dessa maneira, objetivou-se verificar a existência registros solturas disponíveis na web, mídia social Youtube™ Brasil. busca por vídeos situações ou descarte foi realizada entre julho dezembro do ano 2018, totalizando-se 616 horas busca. Como resultado, obteve-se 48...
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...
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...
Aim: To verify variations of early fish stages through density, species composition and ecological attributes in the lower Paranapanema River. Methods: The Canoas I II reservoirs were sampled during three reproductive periods (RP´s) between 2012 2015. Eggs larvae collected using conical-cylindrical plankton nets juveniles by seines sieves. After euthanasia fixation, samples identified at lowest taxonomic level grouped according to their strategy life history. Variations eggs, larvae,...
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...
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...
Objetivo: quantificar a abundância e biomassa de moluscos bentônicos no Lago Igapó I, Londrina, Paraná, Brasil. Material Métodos: foram realizadas duas coletas primeira em junho 2015 segunda fevereiro 2016. O substrato (incluindo os incrustados) foi amostrado utilizando um quadrante com área 1 m2, onde 10 amostragens entre três pontos distintos do lago. Os capturados anestesiados eutanasiados por superexposição ao gelo. Posteriormente, o material quantificado (n) total (kg), armazenado...
This study presents the first record of sardine Platanichthys platana (Regan, 1917) in Paranapanema River basin and provides insights into species' ecological traits. A total 164 juveniles adults were sampled 2019 2020 Lower River. Morphological analyses confirmed species identification, while reproductive revealed different age classes among individuals, with higher sex ratio females mature gonads. Additionally, stomach indicated a diet primarily composed insects, followed by...
Abstract In this study, the authors report morphological deformities in driftwood catfish Trachelyopterus galeatus (Auchenipteridae), an invasive occurring Upper Paraná River basin, Brazil. The frequency of anomalous individuals reached 18.3% all catches. X‐ray images showed anomalies, or total absence structures, pelvic girdle. also observed adipose fin and mental barbels. These findings are extreme importance for evidencing anthropogenic impact on aquatic communities as region suffers...
Understanding the potential distribution of non-native species can be an important tool in preventing biological invasions. We recorded for first time Psellogrammus kennedyi , a small characiform, Lower Paranapanema River, Brazil. According to environmental variables and prediction modeling, presents high Upper Paraná river basin. The model used herein is efficient determine where may able establish. This approach as preventive measure, once control eradication measures are often...
Studies on length-weight relationships are of great importance in fishery assessments. These studies substantial to evaluate fish population dynamics, and communion with the relative condition factor, could provide an estimation potential acting environmental conditions. In this paper, we evaluated length weight relationship factor small sized species. Fish were sampled quarterly between years 2012-2013 2018-2020 lagoons tributaries Rosana Taquaruçu reservoirs, located at lower Paranapanema...
