“…Many populations of I. whitei have declined or disappeared during the last 25 years, largely because of predation by or competition from non-native fish species (e.g., Contreras-MacBeath et al 1998) and water pollution. Non-native species now dominate many areas of the Balsas River basin.…”

“…In many springs and lakes of central Mexico, non-native fish species such as Cyprinus carpio (Cyprinidae), Ictalurus punctatus (Ictaluridae), Oncorhynchus mykiss (Salmonidae), Micropterus salmoides (Centrarchidae), or Oreochromis aureus (Cichlidae) have been stocked to provide a food source (Lyons et al 1998; Moncayo-Estrada et al 2012; Gesundheit and Macías-García 2018). Smaller-bodied non-native fish species such as poeciliids often arrive as contaminants from these stockings or as escapees or direct releases of aquarium fish (Contreras-MacBeath et al 1998; Lyons et al 1998; Moncayo-Estrada et al 2012, 2015; Gesundheit and Macías-García 2018). The interactions of goodeids with non-native species are generally poorly documented or understood (Ramírez-Carrillo and Macías-García 2015; Ramírez-García et al 2018), but in almost all cases the establishment of one or more non-natives is associated with declines in abundance of the goodeids (e.g., Soto-Galera et al 1998, 1999; Gesundheit and Macías-García 2018).…”

The current distribution and abundance of the 40 species of Goodeidae fishes known from Mexico are described, and a total of 84 Evolutionarily Significant Units (ESUs) is designated within these species. Two species and four ESUs are likely extinct with no captive populations, and three species and eight ESUs are probably extinct in the wild but have at least one captive population in Mexico, the United States, or Europe. Of the 35 extant species, the analyses indicate that nine should be considered as critically endangered, 14 as endangered, nine as vulnerable, and only three as least concern. Twenty-seven of these species have experienced substantial declines in distribution or abundance or both since 2000, and only eight appear to have remained relatively stable. Of the 72 extant ESUs, our analyses indicate that 29 should be considered as critically endangered, 21 as endangered, 18 as vulnerable, and only four as least concern. Brief summaries of the historic and current distributions and abundance of each species are provided, as well as ESU. Three strategies are recommended to conserve Mexican goodeids: protect the best-quality remaining habitats where goodeids still persist, restore degraded habitat and re-introduce species or ESUs where practical, and establish captive populations to ensure continued survival of the many species and ESUs that will almost inevitably go extinct in the coming years. Limited resources require cooperation and collaboration between scientists, conservationists, and aquarium hobbyists for successful captive maintenance.

“…There are now established populations in at least 72 different countries across the globe [33]. This includes Mexico [34], where they are found in many localities including the Lerma-Santiago River system, the main basin of the Mexican High Plateau and a watershed noted for its high levels of endemicity. Endemics include Goodeinae, a clade consisting of ca 45 species of small livebearing fish [35], 17 of which are included in the IUCN Red List of Threatened Species [36] (see also [37,38]).…”

Exotic invaders gain foraging benefits by shoaling with native fish

et al. 2014

Freshwater habitats are under increasing threat due to invasions of exotic fish. These invasions typically begin with the introduction of small numbers of individuals unfamiliar with the new habitat. One way in which the invaders might overcome this disadvantage is by associating with native taxa occupying a similar ecological niche. Here we used guppies (Poecilia reticulata) from a feral population in Mexico to test the prediction that exotic shoaling fish can associate with heterospecifics, and that they improve their foraging efficiency by doing so. Guppies have invaded the Mexican High Plateau and are implicated in the declines of many native topminnow (Goodeinae) species. We show that heterospecific associations between guppies and topminnows can deliver the same foraging benefits as conspecific shoals, and that variation in foraging gains is linked to differences in association tendency. These results uncover a mechanism enabling founding individuals to survive during the most vulnerable phase of an invasion and help explain why guppies have established viable populations in many parts of Mexico as well in every continent except Antarctica.

“…Such species also often show high tolerance to stressful physical and chemical factors in the environment. Together with the absence of natural predators, such invasive species are often highly successful once they are established in new locations (Contreras-Macbeath et al 1998). In aquatic systems, the presence of IAS such as loricariids may also affect water quality, as they dig large galleries to build their nests.…”

“…For example, in the lower Balsas River region (Mexico), the presence of Armed Fish, Pterygoplichthys disjunctivus (C. Weber, 1991), has reduced the catch of tilapia, with annual losses estimated to be 36 million Mexican pesos (Mendoza et al 2007). In addition, species of Doradidae and Loricariidae from South America have been detected worldwide as IAS in aquatic systems due to their high commercialization value as ornamental fish (Contreras-Macbeath et al 1998).…”

First records of Agamyxis pectinifrons (Cope, 1870) (Siluriformes, Doradidae) from the state of Chiapas, Mexico, and an extension of the geographic range in the Grijalva river basin

We provide the first records of occurrence of Spotted Raphael Catfish, Agamyxis pectinifrons, in Chiapas, Mexico, and extend the geographic range of this species in the Grijalva river basin. We collected 42 specimens, for which we present morphological and meristic data from 28 of these. The larger number of individuals and the range of sizes recorded suggest that A. pectinifrons is established in this region of the Grijalva basin.
