Finding of a single successful introduction and strong invading potential of the female specimen of Amazon sailfin catfish does not imply Amazon sailfin catfish in the recipient area. The automatically its occurrence, i.e., introduction into the acclimatization of the Amazon sailfin catfish in southern Danube River ecosystem, regardless of the ripeness of her United States started after the allegedly releasing from gonads (Figure 3) in late summer period. Having in mind the aquaria into lakes, ponds and rivers, e.g., in Florida, in early optimal temperature range for this tropical fish species, an 1970’s, where for years only single fish was caught annually, establishment event for it seems fair unlikely. However, both until recently (the lag phase of acclimatization), when the FISK and IFRA scores it gained (26 and 61, respectively) population there suddenly boomed. Samat et al.

... All known quantitative risk screenings of the potential invasiveness of Pterygoplichthys spp. have been carried out using both FISK (Simonović, Nikolić, and Grujić, 2010;Marr et al., 2017;da Silva, 2019;Saba et al., 2020) and AS-ISK (Tarkan et al., 2017;Suresh et al., 2019). To date, the only application of AS-ISK in Vietnam including a screening for P. pardalis was recently carried out by Ruykys et al. (Ruykys et al., 2021). ...
The invasion risk of non-native suckermouth catfishes Pterygoplichthys spp. in the River Dinh (Vietnam) was evaluated using two related decision-support tools, namely the Fish Invasiveness Screening Kit (FISK) and the Aquatic Species Invasiveness Screening Kit (AS-ISK). The results of screenings obtained independently by three assessors using both toolkits were evaluated for consistency, and compared with a screening study previously obtained for Vietnam as a wide risk assessment area. Both FISK and AS-ISK based screenings were shown to provide adequate and potentially important outcomes in terms of risk of invasiveness and were consistent amongst assessors and between toolkits. The invasion risk of Pterygoplichthys in the River Ding was found to be high and the traits of these fishes that influence their success of becoming established were considered. Some aspects in the use of FISK and AS-ISK as decision-support tools as part of the overall risk analysis of species’ invasions for large risk assessment areas are discussed.

An intensive survey was undertaken and reported the existence of an invasive armoured sailfin catfish Pterygoplichthys pardalis from the Bharathapuzha River, Palakkad, Kerala, India, and its invasion as one of the foremost threats to the endemic aquatic biodiversity of Kerala. It belongs to the Genus Pterygoplichthys (Siluriformes: Loricariidae) which is known as popular aquarium fish that constitutes one of the most successful aquatic freshwaters invasive taxa, having achieved global distribution. The invasion occurred through aquarium fish culture and trading and is intensified by the distribution through rainstorm flooding and irrigation canal. The fish were identified based on morphological tests, identified fishes ranged in length (9.50-31.75cm) and weight (8.16-129.80 g). Distribution leads to understanding the changes and disturbances in fish species composition and the negative impact on the riverine ecosystem.
... Sailfin catfish is not a native Indonesian fish, it originated from the Amazon river basin, South America [9,10]. Invasion of fish from the genus Pterygoplichthys from the family Loricariidae, its released into inland open water (river, lake, reservoir) and its growing population in tropical and subtropical freshwater bodies has serious ecological consequences [11,12,13]. ...
Bengawan Solo river 548.53 km is the longest river in Java Island Indonesia, which crosses provinces of Central Java and East Java. Bengawan Solo river is heavily polluted by agricultural, industrial and domestic wastes, especially in Surakarta Residence, Central Java. The impacts of pollution in Bengawan Solo river are poor water quality, the population of native fish has declined sharply and some were almost extinct. The fish that develop was Sailfin catfish ( Pterygoplichthys pardalis ) because these fish were resistant to pollution. The study aimed to determine the growth parameters of Sailfin catfish ( P. pardalis ) in Bengawan Solo river. Estimation of growth parameter using length frequency data analysis was done using the FISAT program package. The results of growth parameters of Sailfin catfish ( P. pardalis ) showed that infinity length (L∞) = 41.75 cm; acceleration of growth (K) = 0.48 cm/year. Natural mortality (M) = 1,1; fishing mortality (F) = 2.47; and total mortality (Z) = 3.57. Exploitation rate (E) = 0.69. The conclusion is the fishing mortality of Sailfin catfish is quite high, while natural mortality is low because the fish are resistant to pollution.

Besides, it is expected that global climate change effects favor species invasion, exacerbating aquatic environments species introduction vulnerability (Dukes et al., 2009 Pterygoplichthys genus has a history of introductions in many places and has a damaging reputation in countries where it has been introduced, such as Canada (Mendoza et al., 2009), United States (Florida, Hawaii, Nevada, Texas, California), Puerto Rico (Courtenay et al., 1984;Rodríguez-Barreras et al., 2020), Jamaica (Jones, 2008), Philippines (Chavez et al., 2006), Taiwan (Shih-Hsiung et al., 2005, Liang & Shieh, 2005, Singapore (Tan & Tan, 2003), Vietnam (Zworykin & Budaev, 2013), Serbia (Simonović et al., 2010), Costa Rica (Bussing, 2002), and Mexico, where the species are established in Balsas and Mezcala rivers in Michoacan state (Conabio, 2004;Imac, 2005;La Jornada, 2005), Amacuzac River, Morelos (Trujillo-Jiménez, 2003), and Catazajá and Medellín lagoons (Wakida-Kusunoki et al., 2007). ...
Aim:
We report Pterygoplichthys pardalis introduction - a freshwater fish species from the Amazon river basin - in the Cauca river basin and in Salvajina and Calima dams, Colombia.
Scope:
We registered and taxonomically evaluated P. pardalis to verify its identification, seeking to avoid the elimination of native morphologically similar species.
Methodology:
Material deposited in some ichthyology collections was examined, evaluating 35 morphometric characters for identification following Armbruster’s keys. These results were compared with the available literature for Pterygoplichthys genus.
Conclusions:
This article reports some identification errors, mainly regarding Pterygoplichthys undecimalis, which actually correspond to P. pardalis. We also suggest two possible mechanisms that explain P. pardalis introduction into national basins: i) oversights during ornamental fish species trade and by their buyers, and ii) aquaculture projects that, seeking to “improve” regional economy, not take into consideration characteristics and suitability of the species they seek to promote. Finally, this article alerts about P. pardalis introduction in national basins and their possible effects on native species and ecosystems.
... The two South American fish species recorded in Serbia, Amazon sailfin catfish (Pterygoplichthys pardalis) and guppy (Poecilia reticulata), were most probably released by aquarists. Only a single individual of the Amazon sailfin catfish was registered in the Danube (Simonović et al. 2010), while a stable population of the guppy was recorded in a termal stream near the city of Niš (Milenković et al. 2013). Although the Amur sleeper (Perccottus glenii) invaded the Danube River only recently (Hegediš et al. 2007;Jarić et al. 2012), it is one of the most widespread non-native invasive fish species in Eurasia (Reshetnikov and Ficetola 2011). ...
The Danube River basin represents a hotspot for the European freshwater diversity. The Danube in Serbia is characterized by a significant level of fish diversity, as well as by economically important fish resources. However, the Danube fish fauna is facing a number of adverse anthropogenic impacts, such as unsustainable fishery, habitat loss and fragmentation, water pollution and non-native species invasions. In this chapter, the major adverse impacts on the Danube fish communities in Serbia are presented, and the critical management measures are discussed, such as those related to supportive stocking and other conservation efforts. In order to ensure adequate protection and sustainable management of fish resources in the Danube in Serbia, it will be critical to introduce effective monitoring system, to establish and enforce adequate management measures, and to intensify research efforts on critical issues related to fish management and conservation.
... have established in several countries (Copp et al. 2005), the information on their biology, ecology, establishment, and abundance, which is important for managing its spread, is not widely DOI: 10.3750/AIEP/02551 available. Food habits of Pterygoplichthys disjunctivus (Weber, 1991) were investigated in the USA (Nico andMartin 2001, Hoover et al. 2004) and Serbia (Simonović et al. 2010); sex ratio-in the Philippines (Jumawan et al. 2016), Hawaii (Yamamoto and Tagawa 2000), and Taiwan (Liang et al. 2005); fecundity-in the USA (Gibbs et al. 2008(Gibbs et al. , 2017, Mexico (Rueda-Jasso et al. 2013), and the Philippines (Jumawan et al. 2016); and the size at first maturity and breeding period-in the USA (Gibbs et al. 2008), the Philippines (Jumawan and Herrera 2014), and Mexico (Rueda-Jasso et al. 2013). These parameters might differ within and/or across the regions of its occurrence. ...
The East Kolkata Wetlands in India (a Ramsar site) are sewage-fed, nutrient-rich water bodies successfully used for fish production. The vermiculated sailfin catfish, Pterygoplichthys disjunctivus (Weber, 1991), exotic to India, has invaded these wetlands. The management and control of this catfish has been hindered, because of the lack of information on its abundance, population structure, biological traits, level of establishment, and competition with native fish species. Within 2013–2015 studies were carried out on the population structure of P. disjunctivus, its food habits, reproductive biology, and initial impacts in the wetlands through monthly and seasonal collection of samples, examination of food items, reproductive parameters, catch data, and gathering fishers experience. The length (TL) and weight of the specimens ranged from 10 to 55 cm and from 120 to 1250 g, respectively. Major food items of the catfish were detrital matter (%IRI 56), unidentified plant matter (%IRI 11), fish eggs (%IRI 11), polychaete worms (%IRI 5), and other minor items (%IRI 0.3 to 4). At 50% similarity, the food items of P. disjunctivus overlapped with that of Macrognathus pancalus, Channa punctata, Nandus nandus, Anabas testudineus, Clarias batrachus, Oreochromis niloticus, Cirrhinus mrigala, and Cyprinus carpio, while at 80% it overlapped with that of C. mrigala and C. carpio. The fecundity of P. disjunctivus, in the wetlands, was the highest recorded for the species. Females attained the first maturity at 24 cm TL and reproduced multiple times within July–November. The breeding period of the species overlapped with 13 native fish species, of which it seriously overlapped with that of Gudusia chapra, Amblypharyngodon mola, Pethia conchonius, P. ticto, N. nandus, C. punctata, and A. testudineus. The sailfin catfish has established reproducing populations in the wetlands and reached ‘invasive’ proportions constituting 4.83% (300.04 t·year–1) of the mean annual fish catch (6203.85 t·year–1) from the wetlands. The invasive risk assessment showed a high risk of the species in the current scenario and probable climate change scenarios in future in the region. Pterygoplichthys disjunctivus has successfully colonized the sensitive East Kolkata Wetlands, which might easily spread to neighboring water bodies including the sensitive Ganga River and Sundarban mangroves and cause ecological and economic disturbance unless preventive measures are taken as the species has high invasive risk in the region.
... Their quick adaptability to captivity conditions and popularity among aquarists for more than two decades have led to their introduction and dispersion in non-native distant ecosystems (Wakida-Kusunoki et al. 2007). They are very efficient invaders with a large geographic distribution, currently known to inhabit North and Central America, some islands of the western Caribbean (Guzmán and Barragán 1997;Nico and Fuller 1999;Hoover et al. 2004;Chávez et al. 2006;Hubilla et al. 2007;Wakida-Kusunoki et al. 2007;Hossain et al. 2008;Levin et al. 2008;Krishnakumar et al. 2009;Nico et al. 2009a;Trujillo-Jiménez et al. 2010;Wathsala and Upali 2013), Southeast Asia (Bunkley- Williams et al. 1994;Nico and Martin 2001;Tan and Tan 2003;López-Fernández and Winemiller 2005;Chávez et al. 2006;Page and Robins 2006;Gibbs et al. 2008;Hubbs et al. 2008;Neal et al. 2009;Nico et al. 2009b), and eastern Europe and Near East (Ozdilek 2007;Keszka et al. 2008;Simonović et al. 2010;Emiroğlu et al. 2016). ...
The dispersion of invasive alien species has become a global ecological and conservation crisis. Specifically, aquatic emergent invasive alien species constitute a major threat to the economic and environmental health of marine and coastal ecosystems. The Mexican part of the Gulf of Mexico and its associated hydrological basins are currently affected by some of these alien bioinvaders. During the last two decades, a rapid colonization and proliferation of two fish species complexes and two decapod alien species has been documented in this area. The main hydrological basins draining into the GoM have been invaded by the species complex of armored catfishes of the genus Pterygoplichthys and by the Australian red-claw crayfish Cherax quadricarinatus. In regard to coastal and marine environments, the invasive species are represented by the lionfish complex (Pterois spp.) and the giant tiger shrimp Penaeus monodon. Given their rapid expansion and potential direct interaction with the fishing sector and ecosystem structure, they must be analyzed as a single unit and from a big basin integrated perspective. Apart from the visible effects that some of these species may have on non-native locations, their full impact may not be immediately apparent. One of the main concerns for the Mexican public administration is the quantification and forecast of the effects derived from the population expansion of these invaders. Under this perspective, this chapter presents a spatial-detailed integration of the four emergent species/complexes that have invaded the Mexican portion of the extended GoM basin, as well as the temporal evolution of the process. Although effective solutions to control these invasive species are a long way off, several innovative initiatives are being developed in many communities. As an example, the promotion of the lionfish as a gourmet product soon became widespread among fishermen and restaurant owners, allowing its local control through specific fishing practices. The more specific our understanding is of the negative effects caused by the invaders, the more specifically we can address the mitigation of their threats; thus we hope that, by raising general awareness, the effects of these aquatic emergent invasive alien species will be reduced in the future. Meanwhile, a tight cooperation between decision-makers, politicians, and fishermen remains the only way to effectively manage the threat posed by these taxa.
... Among commonly-traded freshwater ornamental fishes, suckermouth armoured catfishes of the family Loricariidae and genus Pterygoplichthys T.N. Gill native to inland water bodies of South America, have established successful invasive populations throughout the world (Fuller et al. 1999;Nico and Martin 2001;Nakabo 2002;Chavez et al. 2006;Joshi 2006;Page and Robins 2006;Armando et al. 2007;Ozdilek 2007;Hossain et al. 2008;Keszka et al. 2008;Nico et al. 2009;Piazzini et al. 2010;Simonović et al. 2010;Wu et al. 2011;Gibbs et al. 2013;Golani and Snovsky 2013;Jones et al. 2013;Rueda-Jasso et al. 2013;Sumanasinghe and Amarasinghe 2013;Zworykin and Budaev 2013;Ishikawa and Tachihara 2014;Jumawan and Herrera 2014;Wei et al. 2017).

Loricariid catfishes of the genus Pterygoplichthys are native to South America and have been introduced in many localities around the world. They are freshwater fishes, but may also use low-salinity habitats such as estuaries for feeding or dispersal. Here we report results of a field survey and salinity-tolerance experiments for a population of Pterygoplichthys sp. collected in Kerala, India. In both chronic and acute salinity-tolerance trials, fish were able to withstand salinities up to 12 ppt with no mortality; however, fish transferred to salinities > 12 ppt did not survive. The experimental results provide evidence that nonnative Pterygoplichthys sp. are able to tolerate mesohaline conditions for extended periods, and can easily invade the brackish water ecosystems of the state. Further, Pterygoplichthys sp. from Kerala have greater salinity tolerance than other congeners. These data are vital to predicting the invasion of non-native fishes such as Pterygoplichthys spp. into coastal systems in Kerala and worldwide. This is particularly important as estuarine ecosystems are under threat of global climate change and sea-level rise. In light of the results of the present study and considering the reports of negative impacts of the species in invaded water bodies, management authorities may consider controlling populations and/or instituting awareness programmes to prevent the spread of this nuisance aquatic invasive species in Kerala.

... The current status, distribution or potential impact of the guppy in both countries is unknown. However, recent research in Serbia suggests that the guppy (found in 1970) has become naturalized in a thermal stream, together with other ornamental organisms, allochthonous plant species (Vallisneria spiralis, Elodea canadensis and Lundwigia repens) and the alien snail Melanoides tuberculate(Milenković et al., 2014).The Amazon sailfin catfish, native to the Amazon River Basin of Brazil and Peru, is a new non-indigenous fish species recorded in the Serbian section of the Danube River at river km 1026, making this the first report for the inland waters of Europe(Simonović et al., 2010).The status of this species in the Danube is unknown, although it may negatively impact the aquatic food base and native invertebrate and vertebrate species(Nico & Martin, 2001).Eurasian ruffe (Gymnocephalus cernua, Percidae), which is native to the Caspian, Aral, Black, Baltic and North Sea basins, Siberia(Petriki, Naziridis, Apostolou, Koutrakis, & Bobori, 2014), occurs in the Balkan countries situated in the Danube River Basin. This species has been recorded in several aquatic ecosystems outside of its native range, both in Europe and in North America(Brown, Selgeby, & Collins, 1998;Hume, Adams, Bean, & Maitland, 2013). ...
