“…The Lake Bacalar water basin has been recognized as one of the hydrological basins with highest priority for conservation by the Mexican National Commission for the Use and Knowledge of the Biodiversity (CONABIO) [79]. Fortunately, most wetlands and lakes in this region are relatively pristine, excepting the Hondo River on the border between Mexico and Belize, which has been heavily impacted by the discharge of organic waste and pesticides, by vegetation clearing, and by the introduction of invasive such as tilapia [80], and the Amazon sailfin catfish ( Pterygoplichthys pardalis ), which was recently detected [59,81,82] near La Unión [59]. The impact of this declining water quality and the rising incidence of invasive species on the native fish fauna needs to be carefully monitored and eDNA-based studies could provide a cost-effective way to meet this need.…”

Environmental DNA (eDNA) is an effective approach for detecting vertebrates and plants, especially in aquatic ecosystems, but prior studies have largely examined eDNA in cool temperate settings. By contrast, this study employs eDNA to survey the fish fauna in tropical Lake Bacalar (Mexico) with the additional goal of assessing the possible presence of invasive fishes, such as Amazon sailfin catfish and tilapia. Sediment and water samples were collected from eight stations in Lake Bacalar on three occasions over a 4-month interval. Each sample was stored in the presence or absence of lysis buffer to compare eDNA recovery. Short fragments (184–187 bp) of the cytochrome c oxidase I (COI) gene were amplified using fusion primers and then sequenced on Ion Torrent PGM or S5 before their source species were determined using a custom reference sequence database constructed on BOLD. In total, eDNA sequences were recovered from 75 species of vertebrates including 47 fishes, 15 birds, 7 mammals, 5 reptiles, and 1 amphibian. Although all species are known from this region, six fish species represent new records for the study area, while two require verification. Sequences for five species (2 birds, 2 mammals, 1 reptile) were only detected from sediments, while sequences from 52 species were only recovered from water. Because DNA from the Amazon sailfin catfish was not detected, we used a mock eDNA experiment to confirm our methods would enable its detection. In summary, we developed protocols that recovered eDNA from tropical oligotrophic aquatic ecosystems and confirmed their effectiveness in detecting fishes and diverse species of vertebrates.

“…Records have been reported from Texas, Nevada and Florida, USA (Fuller et al, 1999;Capps, 2008, Gibbs et al, 2008Pound et al, 2011), Puerto Rico (Bunkled-Williams et al, 1994), Taiwan (Liang et al, 2005(Liang et al, , 2006, the Philippines (Chávez et al, 2006), Vietnam (Levin et al, 2008), Java and Australia (Capps, 2008), Bangladesh (Hoosain et al, 2008), Turkey (Ozdilek, 2007), Poland (Keszka et al, 2008) and Italy (Piazzini et al, 2010); a recent Danube invasion has also been reported (Simonovic et al, 2011). Several studies report the invasion of loricariids in Mexico (Guzman and Barragan, 1997;Mendoza et al, 2007;Okolodkov et al, 2007;Wakida-Kusonoki et al, 2007;Wakida-Kusunoki and Amador-del Angel, 2008;Capps et al, 2011).…”

“…In Mexico, the sailfin catfish was detected for the first time in the Mezcala River, Guerrero (Balsas Basin), in 1995 (Guzmán and Barragán, 1997) and later in Tecpatan, Chiapas, the surroundings of Villahermosa, Tabasco (Mendoza et al, 2007), and in the Grijalva-Usumacinta Basin (Tabasco and Chiapas) (Wakida-Kusunoki et al, 2007;Wakida-Kusunoki and Amador del-Angel, 2008). The first specimens were identified as Liposarcus multiradiatus, a synonym of Pterygoplichthys multiradiatus (Armbruster, 2004); however, the species is currently identified as P. disjunctivus (Armbruster pers.…”

Invasive Pterygoplichthys disjunctivus (Weber, 1991) (synonymy: Liposarcus multiradiatus) armored catfish were first reported in Mexico in 1995 and have spread successfully in several aquatic ecosystems. In Adolfo López Mateos El Infiernillo Reservoir, Michoacán -Guerrero, the population of this armored catfish is growing substantially because natural predators are not present and exploitation by humans does not occur. Over a complete annual cycle, we studied the following population parameters: weight, total and standard length, the relationship of weight to total length, the hepatosomatic (HSI) and gonadosomatic (GSI) indices, total fecundity (TF) and relative fecundity (RF). The average total (TL) and standard lengths (SL) were 248 ± 37.5 and 188 ± 30.7 mm, respectively, and the average weight (W) was 135.3± 66.8 g. The largest fish reported was 520 mm in TL and weighed 1 280 g. The species showed an extended reproductive season from May to November, as indicated by the GSI, TF and RF. The strongest reproductive peak occurred from July through October. During the annual cycle, the highest monthly average fecundity was 2 447 eggs, and the average relative fecundity was 12.6 eggs per g of fish (August and September). This information will be crucial for calculating the current biomass and future growth of the population. The calculation of these results could provide a basis for the exploitation of this resource for human consumption and animal feeds.
