“…and InvBasa, to provide awareness about new invasions (Adriaens et al, 2015;Wallace et al, 2016, Fundacion Humedales, 2017. Lastly, and more importantly, it is necessary to implement educational programs to provide high-quality information to hobbyists, retailers and fish farmers (Azevedo-Santos et al, 2015), as for example, informing about threats 8 e170033 [8] related to the introduction of non-native fish, and the list of invasive species forbidden in the market (e.g. Federal Law 203 of 2008 which prohibits the importation of P. hypophthalmus).…”

“…For example, excessive growth and unexpected aggressive behavior of fishes may lead to environmental problems, i.e, aquarium dumping (Duggan et al, 2006;Gertzen et al, 2008). Under these circumstances, many hobbyists are poorly informed about adequate practices (i.e, correct disposal of pets or even sacrifice), and discard unwanted pets into nearby waterways (Duggan et al, 2006;Gertzen et al, 2008;Magalhães, Jacobi, 2013a;Azevedo-Santos et al, 2015;Maceda-Veiga et al, 2016). Pet abandonment has become one of the most challenging issues in biosecurity concerning species invasions (CBD, 2010).…”

“…In Brazil, where native fish diversity is high (Frehse et al, 2016), official reports of aquarium dumping are rare, but evidence indicates that this activity is frequent and increasing in several regions (Gomes et al, 2011;Magalhães, Jacobi, 2013a;Garcia et al, 2014;AzevedoSantos et al, 2015;França et al, 2017). There are records regarding small characids, osphronemids and poeciliids (Magalhães, Jacobi, 2013a;Azevedo-Santos et al, 2015), but the market of large-bodied non-native aquarium fishes may represent an important source of fish propagules. Sales of large ornamental species, known as "tankbusters" among hobbyists, has grown rapidly in the last decade (Magalhães, Jacobi, 2010;Gomes et al, 2011;Magalhães, Jacobi, 2013a;Garcia et al, 2014;França et al, 2017).…”

As ornamental fishkeeping practices spread in Brazil (Gomes et al, 2011;Magalhães, Jacobi, 2013a;Assis et al, 2014;Garcia et al, 2014;Magalhães, 2015), an informal trade system has developed among hobbyists, which is currently nonregulated, non-monitored and apparently not recognized by environmental agencies (Magalhães, 2015).…”

Informal sales of large-bodied non-native aquarium fishes (known as "tankbusters") is increasing among Brazilian hobbyists. In this study, we surveyed this non-regulated trade on Facebook ® from May 2012 to September 2016, systematically collecting information about the fishes available for trading: species, family, common/scientific names, native range, juvenile length, behavior, number of specimens available in five geographical regions from Brazil. We also assessed the invasion risk of the most frequently sold species using the Fish Invasiveness Screening Test (FIST). We found 93 taxa belonging to 35 families. Cichlidae was the dominant family, and most species were native to South America. All species are sold at very small sizes (< 10.0 cm), and most display aggressive behavior. The hybrid Amphilophus trimaculatus × Amphilophus citrinellus, Astronotus ocellatus, Uaru amphiacanthoides, Osteoglossum bicirrhosum, Cichla piquiti, Pangasianodon hypophthalmus, Datnioides microlepis and Cichla kelberi were the main species available. The southeast region showed the greatest trading activity. Based on biological traits, the FIST indicated that Arapaima gigas, C. kelberi and C. temensis are high-risk species in terms of biological invasions via aquarium dumping. We suggest management strategies such as trade regulations, monitoring, euthanasia and educational programs to prevent further introductions via aquarium dumping.Keywords: Aquarium releases, Aquarium trade, Biological invasions, Invasiveness, Propagule pressure.A venda de juvenis de peixes não-nativos de grandes dimensões, chamados de "peixes jumbo", está aumentando entre aquaristas no Brasil. Neste trabalho, pesquisou-se este comércio informal pelo Facebook ® de maio/2012 a setembro/2016, coletando-se informações sobre espécies, família, nomes vulgares/científicos, origem, tamanho juvenil, comportamento e número/frequência de exemplares disponíveis nas cinco regiões geográficas do Brasil. Também avaliou-se o risco de invasão das espécies mais vendidas usando o protocolo Fish Invasiveness Screening Test (FIST). Foram encontradas 93 espécies pertencentes a 35 famílias. Cichlidae foi a família dominante, e a maioria das espécies é nativa da América do Sul. Todas as espécies foram vendidas como juvenis (< 10.0 cm), e a maioria exibe comportamento agressivo. O híbrido Amphilophus trimaculatus × Amphilophus citrinellus, Astronotus ocellatus, Uaru amphiacanthoides, Osteoglossum bicirrhosum, Cichla piquiti, Pangasianodon hypophthalmus, Datnioides microlepis e Cichla kelberi foram as espécies mais comercializadas. A região sudeste apresentou a maior porcentagem de vendas, e o FIST mostrou que Arapaima gigas, C. kelberi e C. temensis foram consideradas de alto risco para desencadear invasões biológicas mediadas por descarte de aquários. Recomendações como a regulação do comércio, monitoramento, sacrifício das espécies e campanhas educacionais para os aquaristas são sugeridas para evitar futuras introduções de peixes via descarte de aquários.

“…In Brazil, fish species introductions have been increasingly reported in the literature in recent years (Orsi and Agostinho, 1999;Alves et al, 2007;Magalhães, 2010;Azevedo-Santos et al, 2015), although the actual number of non-native species is supposed to be underestimated (Vitule, 2009;Magalhães and Jacobi, 2010;Azevedo-Santos et al, 2015). Therefore, it is worth emphasizing the importance of reporting the presence of any non-native species in natural, semi-natural or artificial environments in any region of the country.…”

In Brazil, more than 150 non-native fish species have been introduced either intentionally or unintentionally, mainly due to aquaculture, fishery improvement and ornamental trade. The non-native jaguar guapote Parachromis managuensis was recorded in two artificial ponds, four rivers, one stream and two reservoirs, ecosystems belonging to the Una, Ipojuca, Capibaribe and Pajeú River basins, Pernambuco, northeastern Brazil. The sampling period was between October 2006 and July 2015. A total of 376 individuals of P. managuensis was captured by seines, casting nets and gillnets. This species may have been introduced in the study sites by accidental release during pond drainage in fish farms, stocking for the purpose of animal protein production or by aquarium dumping. The presence of various ontogenetic life stages in all studied environments is a strong evidence that the species is established. Seven management actions are proposed to prevent further introductions of P. managuensis in other environments of the region.
