“…Additionally, we included records available in grey literature (Penados Saravia 2014) and records from unpublished data in short reports (Cano Alfaro, unpublished data) deposited in the CDC-CECON database. Interactions with the environment and interspecific interactions of plecos with local fauna were described and compiled along with previous literature describing interactions outside the natural range of plecos (Rice et al 2007;Nico 2010;Amador del Ángel et al 2014;Toro-Ramírez et al 2014; Ríos-Muñoz 2015; Wakida-Kusunoki and Toro-Ramírez 2016), expanding on the natural history of Pterygoplichthys as an invasive genus in the rivers of Central America.…”

Fishes have been introduced in non-native ecosystems all over the world. These introductions have been recognised for their overall negative effects on native biodiversity. Plecos (Pterygoplichthys Gill, 1858) have been introduced worldwide due to bad practices in the aquarium trade and, in Central America, there is little information regarding these invasive fishes. Plecos have been demonstrated to be a threat in non-native ecosystems because they interfere with their new ecosystems through bottom-up impacts, altering nutrient availability and interactions with native wildlife. Herein, new records of plecos are reported for river basins from Guatemala in northern Central America where they had not previously been reported. Evidence of interactions of plecos with the native fauna that had not been recorded to date are also included. We compiled a total of 34 records in Guatemala, with eight new records. We present the first records of the genus in a river basin of the Caribbean drainage for Guatemala. Three new interactions of fauna preying upon plecos are presented (Black vulture, Bare-throated tiger Heron and Domestic dog), along with a compilation of previously known interactions. Establishing a monitoring and surveillance programme should be a priority in Guatemala, along with other actions to safeguard the native wildlife that could be at high risk because of biological invasions, such as the one with plecos. In order to better understand this invasion, joint efforts of local fishermen and rangers with State institutions should be promoted.

“…Its invasion success has been attributed to different reasons, such as alteration of bank structure and erosion (Nico et al, 2009), disruption of aquatic food chains (Capps et al, 2011), the presence of parental care and premature reproduction (Rueda-Jasso et al, 2013), and their resistance to certain salinity (Capps et al, 2011). However, the most influential characteristics for its success are that the females are highly prolific and iteroparous reproducers (Gibbs et al, 2013) combined with the lack of predators in the new invaded water catchments (Rueda-Jasso et al, 2013;Toro-Ramírez et al, 2014). However, although Toro-Ramírez et al (2014) indicated that the common snook (Centropomus undecimalis [Bloch, 1792]) could be a predator (reported only in one location) of the species, the invasion has continued, and its population has grown.…”

Shelf-life of loricariid catfish (Pterygoplichthys disjunctivus [Weber, 1991]) roe stored in ice

Recent research has shown the feasibility of using loricariid catfish muscle, either fresh (Marquez-Rios et al., 2016) or as a raw material for gel-type products (unpublished data) intended for human consumption. However, due to the relatively high total fecundity of the species, going from 2000 to 2500 eggs per left gonad (with a maximum capacity of 6,686 eggs) in the summer months (Rueda-Jasso et al., 2013), and its gonad proportion (representing around 30% of the fish weight). It is well recognized that fish roe is a nutritionally rich source, usually thrown away by the fish processors. In this regard, the loricariid catfish roe could also be used as a good source of nutrients since it possesses

“…These impacts could occur anywhere ACF establish an invasive population. Invasive ACF are preyed upon by native piscivorous predators such as common snook ( Centropomus undecimalis ) and the Neotropical cormorant ( Phalacrocorax brasilianus ) [32,33], although their effects on these and other native predators have not been evaluated.…”

Variation in Neotropical river otter (Lontra longicaudis) diet: Effects of an invasive prey species

2019

Predation is one of the main barriers that exotic species may face in newly colonized areas and may help stop or control the potential negative impacts of invasive species in the environment. We evaluated if the consumption of an invasive prey (armored catfish: Pterygoplichtys sp.) affects the dietary niche breadth and trophic level of a native predator (Neotropical river otter: Lontra longicaudis) in northern Guatemala. We examined otter scats from three rivers: two where the invasive armored catfish occurred and one without the invasive fish. Samples were collected two and seven years after the first report of the catfish in the area. We performed gross scat analysis and stable isotope analyses of nitrogen and carbon of fecal matter. Where the invasive armored catfish occurred, it was the main prey item for L. longicaudis. Particularly in the river outside of protected areas seven years after the first report of the catfish, where it accounted for 49% of the otter diet. Concordance was found between the two techniques to estimate dietary niche breadth and trophic level. The dietary niche breath of otters was narrower seven years after the invasion in comparison to two years after the invasion in both invaded rivers, but the extent of the reduction was lesser inside the protected area. Finally, the trophic level of otters also showed a reduction related to the occurrence of the armored catfish in their diet.
