“…Our work identified the introduction of 22 NNFF in Guatemala, adding seven species (i.e., Colossoma macropomum, Hypostomus sp., Lepomis gibbosus, Oreochromis niloticus, O. urolepis, Parachromis dovii, and Salmo trutta) to previous reports for the country (see Kihn-Pineda and Cano 2012;Elías et al 2018;Gaitán et al 2020). We identified aquaculture as the main source of introduction of NNFF (73%, Fig.…”

“…Second, there is a lack of management and control of unintentional releases from aquaculture farms. Third, riverscape connectivity across political boundaries allows the dispersal of non-native species (Schmitter-Soto et al 2015;Esselman et al 2013); and fourth, intentional releases of ornamental fishes by aquarium hobbyists (Elías et al 2018).…”

“…Recently, unique molecular diversity has been uncovered (e.g., Elías et al 2020;Elías et al 2022), and species are still being discovered (e.g., Dallevo-Gomes et al 2020). Currently, 15 NNFF have been reported across the country (Kihn-Pineda and Cano 2012; Elías et al 2018;Gaitán et al 2020) but their distribution and status have not been assessed.…”

“…This agency has continued using NNFF for aquaculture and the stocking of freshwater systems across the country. In addition, popular species in the aquarium trade have been reported (Kihn-Pineda et al 2006;Kihn-Pineda and Cano 2012;Ariano-Sánchez et al 2017;Elías et al 2018;Gaitán et al 2020). Some of these species are considered potentially invasive (e.g.…”

“…3; Table 1). The remaining four introduced aquarium species were reported during the past 20 years (Kihn-Pineda et al 2006;Kihn-Pineda and Cano 2012;Penados Saravia 2014;Elías et al 2018;Gaitán et al 2020), highlighting the aquarium trade as a potential source of new introductions due to bad practices (e.g., intentional release by aquarium hobbyists; Duggan et al 2006) or the increase of aquarium trade in Guatemala. Although there is no evidence of established populations (sensu Blackburn et al 2011) of C. auratus, Hypostomus sp., Piaractus brachypomus, or Poecilia reticulata in Guatemala, these species have successfully established populations in other parts of the world (e.g., Lindholm et al 2005;Schofield et al 2006;Pound et al 2011;Correa et al 2014;Oliveira et al 2014), underscoring the need for active monitoring in the waterbodies where these species have been reported.…”

Non-native freshwater fishes have been introduced to Guatemalan freshwater ecosystems since the beginning of the last century without prior risk assessment or subsequent evaluation of their impacts. We synthesized historical records, and distributional data from a literature review, online databases and museum records of non-native freshwater fishes in Guatemala. We found records for 22 non-native freshwater fishes with the oldest records dating back to 1926. Non-native freshwater fishes were recorded in 64% of the river sub-basins in Guatemala and we identified that at least 12 species have established populations. The Jaguar guapote (Parachromis managuensis) and Tilapias (Oreochromis spp.) are the most widespread non-native fishes. The species of non-native freshwater fishes introduced indicates that they are human selected (e.g., for farming purposes). Our work shows that aquaculture has been the major driver of introductions in the country, but aquarium release has become an important source in the last 20 years. Given the potential impact of non-native freshwater fishes on native fauna and ecosystems, we highlight an urgent need to assess their ecological effects, as well as to establish a fish fauna monitoring program in Guatemala to detect new introductions. Government and non-governmental agencies should promote the use of native species to supply fish demands in alignment with environmental policies and the objectives of the fishing agency in Guatemala.

Freshwater Fishes of Central America: Distribution, Assessment, and Major Threats

et al. 2022

View full text Add to dashboard Cite

Central America contains a rich diversity of freshwater habitats that support more than 600 species of freshwater fishes. However, despite several perceived threats to the integrity of the freshwater habitats throughout the region, a formal analysis of extinction risk for the region’s ichthyofauna is lacking. In this manuscript, we report an updated checklist of species and a novel comprehensive assessment of the conservation status of Central American freshwater fishes by applying the IUCN Red List Categories and Criteria to species at the global level. We also analyze the distribution of freshwater fishes across Central America and generate baseline geospatial data that can be used in multi-species conservation planning processes, which is available through the Red List Website. Our results indicate that between 15 and 28% of freshwater fishes in the region are threatened with extinction, with considerable uncertainty resulting from elevated data deficiency. We identify major and widespread threats in the region, including pollution, agriculture, aquaculture, biological resource use, natural system modifications, invasive species, and land development. This analysis represents an important first step in formulating effective conservation planning and action initiatives for a taxonomic group that historically has received few protections and can be used to inform conservation priorities of freshwater ecosystems at both national and regional scales.
