“…Despite the revenues and jobs generated by the aquarium/ornamental fish trade (reviewed in Tlusty, 2002), it has been identified as a major driver for nonnative fish introductions into the wild, particularly for the freshwater species (Copp et al, 2005;Duggan et al, 2006;Corfield et al, 2008). Also, in the USA, 26% of human-mediated alien fish diversity was attributed to the aquarium trade (Fuller et al, 1999) and 115 freshwater aquarium species have been reported as introduced into the wild (Padilla & Williams, 2004).…”

The aquarium trade has been recognized as an important pathway for the introduction of invasive species around the world. This study investigates the availability of ornamental fish species in ten large-size, centrally positioned aquarium stores that control a large share of imports and the Hellenic market chain, and aims to provide a provisional checklist on the aquarium fish trade in Greece. For each recorded species, additional data concerning various aspects (e.g. natural environment, native range, established as aliens, conservation status and threats to humans) were collected from Fishbase, IUCN red list and the scientific literature. Overall, 326 fish species belonging to 64 families were reported according to the store labels. The majority of the species recorded were freshwater (66%), originating mainly from South America and Asia, while most of the marine species (26%) had primarily an Indo-Pacific native distribution. Among the freshwater fishes, Cichlidae and Cyprinidae were the dominant families with 64 and 27 species, respectively, while the family Acanthuridae dominated within the marine fishes with ten species. The vast majority of both freshwater and marine species (>90%) were tropical. Concerning the presence of alien species, 62 ornamental species have been established outside their natural range, with 22 of them positively confirmed as aliens in the European waters. Moreover, 25 species were listed in the critically endangered (CR), endangered (EN) and vulnerable (VU) categories of the IUCN red list. Even more surprisingly, for 192 species recorded, data were missing to assign their conservation status or had not been assessed at all. Finally, the majority of the species (84%) were harmless to humans. However, 35 species (11%) were recognised as potentially harmful (i.e. venomous, ciguatera poisoning, traumatogenic) and two were found to be poisonous if consumed. In conclusion, the aquarium fish sector in Greece is practically uncontrolled given the presence of: a) threatened species, b) species potentially harmful to humans and c) species capable of establishing non-indigenous populations, if released into the wild.

“…Propagule pressure of NICS is recognized as one of the main factors of establishment (Capinha et al, 2013). Consequently, the quantity of NICS in the pet trade is directly correlated with the probability of their release into the wild and their possible establishment similarly to fish released from aquaria (Duggan et al, 2006). Although a risk assessment for ornamental NICS in the Czech Republic (Patoka et al, 2014a) and an analysis of keeper behaviour (Patoka et al, 2014b) have been published, detailed information focused on the origin of imported ornamental crayfish and their prices and quantities 04p2…”

“…Fishkeeping is increasing in popularity, but hobbyists are poorly informed or reckless about environmentally friendly practices (Duggan et al, 2006;Gertzen et al, 2008;Holmberg et al, 2015;Maceda-Veiga et al, 2016). 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).…”

“…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).…”

Small size today, aquarium dumping tomorrow: sales of juvenile non-native large fish as an important threat in Brazil

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.
