“…Hubbs et al (2008) and our composite drainage basin checklist were the most similar but with differences. Our checklist included three fishes reported in Texas after 2008: native Ameiurus nebulosus (Craig et al 2015), non-native Xiphophorus variatus (Cohen et al 2014), and non-native Hypophthalmichthys nobilis (T. Bister, Texas Parks and Wildlife Inland Fisheries, personal communication 10 March 2019). Fishes included by Hubbs et al (2008) and excluded from our checklist were Cyprinella sp., Cycleptus sp., and Ictalurus sp., because Page et al (2013) did not recognize these three putative species.…”

“…Origins of non-native fishes are from marine waters of Texas and from inland waters of North America and other continents (Table 2). Based on published accounts, non-native fishes were introduced for human consumption and sport (Nico and Fuller 1999), bait bucket releases (Howells 2001), vegetation control (Guillory and Gasaway 1978), accidental aquaculture releases (Howells 2001), and aquarium releases (Cohen et al 2014).…”

“…In addition, species distributions were updated to document range expansions (e.g., Percina carbonaria , Hubbs et al 2008), range contractions (e.g., Ictalurus lupus , Kelsch and Hendricks 1990), and name changes (e.g., Micropterus treculi to Micropterus treculii ) using standardized taxonomic nomenclature (e.g., Nelson et al 2004). Since Hubbs et al (2008), American Fisheries Society and American Society of Ichthyologists and Herpetologists (AFS-ASIH) Committee of Names of Fishes published a revised common and scientific names list (Page et al 2013), new native species were reported within Texas (e.g., Craig et al 2015), a fish name was synonymized (Echelle et al 2013), introduced species became established (e.g., Cohen et al 2014), and species ranges expanded (e.g., Dautreuil et al 2016) and contracted (e.g., Craig et al 2017).…”

Species checklists and dichotomous keys are valuable tools that provide many services for ecological studies and management through tracking native and non-native species through time. We developed nine drainage basin checklists and dichotomous keys for 196 inland fishes of Texas, consisting of 171 native fishes and 25 non-native fishes. Our checklists were updated from previous checklists and revised using reports of new established native and non-native fishes in Texas, reports of new fish occurrences among drainages, and changes in species taxonomic nomenclature. We provided the first dichotomous keys for major drainage basins in Texas. Among the 171 native inland fishes, 6 species are considered extinct or extirpated, 13 species are listed as threatened or endangered by U.S. Fish and Wildlife Service, and 59 species are listed as Species of Greatest Conservation Need (SGCN) by the state of Texas. Red River drainage basin was the most speciose with 120 fishes. Rio Grande & Pecos drainage basin had the greatest number of threatened or endangered fishes (N = 7) and the greatest number of SGCN fishes (N = 28). We revised drainage basin occurrences for 77 species. Drainage basin checklists and dichotomous keys provide finer resolution of species distributions within the geopolitical boundaries of Texas and can reduce probability of errors in fish identification errors by removing species not occurring within a natural boundary.

“…However, fish originating from the ornamental trade are often more cold-tolerant than their wild-type counterparts (e.g. [ 15 ] for Poecilia reticulata ; [ 14 ] for Xiphophorus variatus ). In fact, several studies showed certain tilapias ( Oreochromis spp.)…”

On the occurrence of three non-native cichlid species including the first record of a feral population ofPelmatolapia(Tilapia)mariae(Boulenger, 1899) in Europe

et al. 2017

Thermally influenced freshwater systems provide suitable conditions for non-native species of tropical and subtropical origin to survive and form proliferating populations beyond their native ranges. In Germany, non-native convict cichlids (Amatitlania nigrofasciata) and tilapia (Oreochromis sp.) have established populations in the Gillbach, a small stream that receives warm water discharge from a local power plant. Here, we report on the discovery of spotted tilapia (Pelmatolapia mariae) in the Gillbach, the first record of a reproducing population of this species in Europe. It has been hypothesized that Oreochromis sp. in the Gillbach are descendants of aquaculture escapees and our mtDNA analysis found both O. mossambicus and O. niloticus maternal lineages, which are commonly used for hybrids in aquaculture. Convict cichlids and spotted tilapia were most probably introduced into the Gillbach by aquarium hobbyists. Despite their high invasiveness worldwide, we argue that all three cichlid species are unlikely to spread and persist permanently beyond the thermally influenced range of the Gillbach river system. However, convict cichlids from the Gillbach are known to host both native and non-native fish parasites and thus, non-native cichlids may constitute threats to the native fish fauna. We therefore strongly recommend continuous monitoring of the Gillbach and similar systems.

“…The species has been introduced to nonnative watersheds in tropical and subtropical regions of every continent except Antarctica, which is thought to be due to its popularity in the aquarium trade (Cohen et al. 2014 ). The introduction of Xiphophorus species is associated with concurrent declines in the abundance and diversity of native species, which is a cause for concern among conservation organizations aiming to control the spread of invasive species (Máiz-Tomé et al.…”

We present the complete mitochondrial genome sequence of the Variable Platyfish, Xiphophorus variatus (Meek 1904) (Cyprinodontiformes: Poeciliidae). The genome consists of 16,624 bp which encodes 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs, and 1 control region. Genome-wide nucleotide composition is 27.79% adenine, 31.11% cytosine, 15.63% guanine, and 25.48% thymine. The X. variatus mitochondrial genome shares similar GC content and identical gene order and gene strand location with other members of Poeciliidae. The sequence presented herein will be of utility for future phylogenetic and biomedical research and for designing primers for species detection from environmental DNA samples.
