“…However, knowledge of regulations does not necessarily indicate that some pet shop owners may not import prohibited species. For example, prohibited and invasive amphibians, crayfish and birds were sold in the European Union and Canada, despite regulations (Auliya et al, 2016; Faulkes, 2018; Genovesi et al, 2015; Patoka et al, 2014). This suggests that existing regulations need to be implemented and enforced to prevent the introduction of potentially harmful species.…”

The sale of live non-native animals has become a social norm and is of global concern.The pet trade industry has become one of the main pathways where non-native small mammals are introduced worldwide. We conducted a questionnaire survey in South African pet shops from September 2018 to September 2019 to gain insights into nonnative small mammalian species trade in South Africa. We also investigated whether the pet shop owners were aware of the South African National Environmental Management: Biodiversity Act (NEM: BA; No. 10 of 2004), which regulates and provides management and conservation of the country's biodiversity. A total of 111 pet shop owners/managers responded to the survey, with 26.6% of the owners reporting the sale of birds, 25.1% of fish and 22.5% of mammals. A total of 16 non-native small mammalian species were reported sold, with European rabbits (Oryctolagus cuniculus), Norwegian rats (Rattus norvegicus) and house mice (Mus musculus) being the most commonly sold pets. We found that breeders, animal rescues and pet shops were the major suppliers of small mammal pets, and in terms of the regulation, most respondents (67.8%) were aware of NEM: BA. However, despite the knowledge of the regulations, some of the traded species pose a serious invasion threat. As a result, we recommend increased regulation, monitoring and public awareness to prevent the potential negative impacts associated with non-native mammal species in South Africa.

“…Um comerciante, inclusive, cita a proibição, mas comercializa mesmo assim. Faulkes (2018), em estudo sobre a venda online de espécies de lagostins de água doce, evidenciou que a existência de legislação não tem impedido o comércio online de espécies em províncias do Canadá. Além disso, a falta de capacidade de fiscalização de estabelecimentos que comercializam esta e outras espécies por parte dos órgãos ambientais regionais já é algo bem conhecido (Oliveira & Saldanha 2009).…”

A temática das invasões biológicas tem sido muito debatida nos últimos 20 anos. Estudos demonstram que uma das principais vias de introdução de espécies aquáticas é de origem antrópica, principalmente para fins alimentícios e aquariofilia. Das 481 espécies exóticas invasoras (EEI) já identificadas no Brasil, Procambarus clarkii, conhecido como lagostim-vermelho-da-Louisiana, é uma das mais preocupantes por possuir diversas características biológicas e ecológicas que a torna um invasor perigoso. Apesar de ter seu cultivo e venda proibidos no Brasil desde 2008, há indícios de comércio ilegal. O objetivo do presente estudo foi investigar o comércio ilegal da espécie em estabelecimentos comerciais na Região Sul do Brasil. A coleta de dados foi conduzida através de buscas livres na internet por estabelecimentos comerciais relacionados ao ramo da aquariofilia e posterior contato com os mesmos. No total foram investigados 221 estabelecimentos comerciais dos quais 40 declararam comercializar a espécie. Foi constatado um comércio mais intenso no Paraná (50%), seguido pelo Rio Grande do Sul (32,5%) e por Santa Catarina (17,5%). Somente um estabelecimento que comercializa a espécie mencionou estar ciente da restrição, mas permanece vendendo a espécie. Em relação a características do comércio (número de indivíduos disponíveis a pronta-entrega e preço médio de venda), houve diferenças entre os estados. No Brasil, o comércio ilegal é tido como a principal fonte de novas introduções desta espécie na natureza. Sabidamente, quando uma espécie é adquirida no comércio e por algum motivo, não é mais desejada, há grandes chances de ser solta na natureza. A falta de fiscalização dos estabelecimentos comerciais contribui para a não modificação deste cenário. Sugere-se uma revisão nas listas oficiais de EEI dos estados do Paraná, Santa Catarina e Rio Grande do Sul para inserção do lagostim-vermelho-daLouisiana como espécie de alto risco de invasão.

“…Since then, that tool has been used several times to estimate risk for marbled crayfish in several regions in Europe and each time Marmokrebs has been identified as high risk (Chucholl 2013;Patoka et al 2014;Kotovska et al 2016;Chucholl and Wendler 2017;Uderbayev et al 2017;Weiperth 2019). Because of the invasion history and parthenogenic traits of this species, there is considerable concern that marbled crayfish could escape the pet trade in North America where it is extremely popular into natural habitats (Faulkes 2010(Faulkes , 2018. In North America, bioclimatic species distribution models predict the southeastern and south central USA, Mexico, and Cuba (i.e., warmer areas) would be the most likely to support populations of marbled crayfish (Feria and Faulkes 2011).…”

Invasive species have long been recognized as a serious threat to freshwater ecosystems. This is especially true for invasive species in keystone positions in food webs that can cause major disruption and can lead to unexpected outcomes. Crayfish occupy a central trophic position and non-indigenous crayfish have been shown to substantially disrupt ecosystems they invade. Here, we assess eight non-indigenous crayfish to 21 freshwater ecoregions in Canada using a screening-level risk assessment. We found that ecoregions in Canada that were warmer and contained high native freshwater diversity were most at risk from crayfish invasions, particularly: the Laurentian Great Lakes, St. Lawrence, English-Winnipeg Lakes and Coastal British Columbia ecoregions. Four crayfish species consistently had higher scores: rusty (Faxonius rusticus), virile (Faxonius virilis), signal (Pacifastacus leniusculus), and red swamp (Procambarus clarkii). Of these high-risk crayfish, only the red swamp crayfish is not yet established in Canada but is present in US waters of the transboundary Great Lakes ecoregion. Our study is the first to evaluate the relative risks that non-indigenous crayfish pose to freshwater ecosystems in Canada.
