“…Article eight of this treaty establishes that each country that is party to the Convention has to make efforts to avoid the introduction of non-native species (Alho et al, 2011). One way to greatly reduce the potential impact that aquarium trade may cause on the water bodies of Minas Gerais State is by better informing those involved in this market, such as sectors dealing with importation, breeding, transportation and trading of aquarium fish, as well as hobbyists.…”

A model was developed to assess the risk of invasion of ornamental non-native fishes to six rivers in the state of Minas Gerais, southeastern Brazil, with focus on species popularity. Thirty-nine aquarium shops, in six cities, were visited monthly from January to December 2007. In each city, fish species were identified, and their biology and invasion history information was obtained from the literature. We calculated the annual frequency of occurrence and average number of specimens monthly available in stores. Quarterly water temperature and dissolved oxygen data from 1997 to 2007 were obtained for the Velhas, Muriaé, Uberabinha, Sapucaí-Mirim, Doce and Todos os Santos Rivers from public databases. The invasion risk of each species was assessed through a model comprising nine parameters grouped in four variables: (i) Invasiveness (thermal and dissolved oxygen ranges, diet, parental care or fecundity), (ii) History of invasions (establishment), (iii) Propagule pressure (commercial success, comprising annual frequency of occurrence and number of specimens available monthly at stores), and (iv) Invasibility (water temperature and dissolved oxygen in the target river compatible with the species ranges). Of the 345 ornamental fish species for sale, 332 are non-native to either Minas Gerais (n = 151) or Brazil (n = 194). Based on the proposed cutting values, in particular the compatibility between species and recipient thermal ranges, five ornamental non-native species (Cyprinus rubrofuscus, Carassius auratus, Xiphophorus hellerii, Poecilia reticulata, and P. latipinna) can potentially invade the Velhas and Muriaé Rivers, four species (Cyprinus rubrofuscus, Carassius auratus, X. helleri, and P. reticulata) the Uberabinha River, four species (Cyprinus rubrofuscus, Carassius auratus, X. maculatus, and P. reticulata) the Sapucaí-Mirim River, three species (Carassius auratus, X. hellerii, and P. reticulata) the Doce River, and three species (Cyprinus rubrofuscus, P. reticulata, and Amatitlania nigrofasciata) can potentially invade the Todos os Santos River. Six recommendations are suggested to reduce the invasion risk of non-native fish on the rivers surveyed posed by aquarium trade.Um modelo foi desenvolvido para avaliar o risco de invasão de peixes ornamentais não-nativos em seis rios do estado de Minas Gerais, sudeste do Brasil, com foco na popularidade das espécies. Trinta e nove lojas de aquário em seis cidades foram visitadas mensalmente de janeiro a dezembro de 2007. Em cada cidade, as espécies foram identificadas e suas biologias e histórias de invasão foram obtidas da literatura. Calculou-se a frequência de ocorrência anual e quantidade média mensal de exemplares disponíveis nas lojas. Foram obtidas temperaturas trimestrais da água e dados de oxigênio dissolvido de 1997 a 2007 dos rios Velhas, Muriaé, Uberabinha, Sapucaí-Mirim, Doce e Todos os Santos a partir de bases de dados públicas.

“…The Convention on Biological Diversity, signed by Brazil, establishes in its article eight that each country that is party to the Convention has to make efforts to prevent the introduction, and if possible, control the populations of non-native species (Alho et al, 2011). Given the apparent establishment of P. managuensis in waters of the state of Pernambuco, and the real risk of spread and adverse ecological impacts as already occurs in Gurjão Reservoir, some management recommendations are suggested to avoid further introductions:…”

Novelty on the market, novelty in the environment: The invasion of non-native fish jaguar guapote (Perciformes) in northeastern Brazil

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.

“…According Alho et al (2011), the Pantanal and its surrounding upland plateau have experienced the introduction of various alien species, and researchers have reported that biological invasions have been indicated as one of the main causes of biodiversity loss in the world (Brown and Lomolino, 1998). And the information for fish are much more worrying, because about 50% of fish extinctions in the world may be related to the introduction of exotic species (Clavero and García-Berthou, 2005).…”
