“…However, the only native Lernaea species is Lernaea devastatrix Boxshall, Montú & Schwarzbold, 1997 which parasites wild native fish as well as farmed exotic fish. Lamproglena monodi is another non-native parasite that was introduced together with farming of Nile tilapia (Oreochromis niloticus) and it also infests natural populations of cichlids such as Astronotus ocellatus and Cichla ocellaris, as well as Tilapia rendalli, another exotic cichlid of natural ecosystems (AZEVEDO et al, 2012). Therefore, L. monody is an emerging parasite with pathogenic potential that occurs in the southeastern and southern regions of Brazil.…”

The purpose of this study was to use the informations relating to parasite crustaceans species that was published over the course of one century (1913 to 2013), in order to search for infestation and distribution patterns among these ectoparasites in Brazilian freshwater fish species. This search was carried out on 445 samples of 119 host fish of 27 families within the orders Characiformes, Perciformes, Clupeiformes, Mugiliformes, Osteoglossiformes, Symbranchiformes, Tetraodontiformes and Siluriformes from various regions of Brazil. We organized different host-parasite systems into matrices grouping species at different taxonomic and infestation levels and according to host parameters. Five families of parasites (Ergasilidae, Argulidae, Lernaeidae, Lernaeopodidae and Cymothoidae) distributed into 76 species of 27 genera were analyzed in the host samples, which presented dominance of Ergasilidae species, mainly from the genus Ergasilus. Some crustaceans are host and site-specific, especially in relation to fish in particular habitats and lifestyles (e.g. Perulernaea gamitanae, Anphira branchialis and Riggia paranensis), while other parasites frequently have no preference (e.g. Lernaea cyprinacea and Braga patagonica). We found broadly similar distribution patterns for some crustacean species among the different localities, whereas other species showed well-defined geographical patterns, and these findings were discussed.Keywords: Amazon, Branchiura, Copepoda, host, Isopoda, parasite. ResumoO objetivo deste estudo foi utilizar as informações relacionadas com espécies de crustáceos parasitas, que foram publicados durante um século (1913 a 2013), para procurar padrões de infestação e distribuição desses ectoparasitos em espécies de peixes de água doce do Brasil. Esta pesquisa foi realizada em 445 amostras de 119 peixes hospedeiros de 27 famílias de Characiformes, Perciformes, Clupeiformes, Mugiliformes, Osteoglossiiformes, Symbranchiformes, Tetraodontiformes e Siluriformes das diversas regiões do Brasil. Foram organizados em matrizes de agrupamento diferentes sistemas parasito-hospedeiros em diferentes níveis taxonômicos, níveis de infestação e parâmetros dos hospedeiros. Cinco famílias (Ergasilidae, Argulidae, Lernaeidae, Lernaeopodidae e Cymothoidae) de parasitos, distribuídos em 76 espécies de 27 gêneros, foram analisados em amostras dos hospedeiros, que apresentaram dominância de espécies Ergasilidae principalmente do gênero Ergasilus. Alguns crustáceos são hospedeiros e sítios-específicos no hospedeiro, especialmente peixes de determinados hábitat e estilo de vida (por exemplo, Perulernaea gamitanae, Anphira branchialis e Riggia paranensis), enquanto outros parasitos não têm qualquer preferência (por exemplo, Lernaea cyprinacea e Braga patagonica). Foram encontrados padrões muito semelhantes na distribuição de algumas espécies de crustáceos entre as diferentes localidades, enquanto outras espécies mostraram um padrão geográfico bem definido, o que foi discutido aqui.

“…According to Douëllou & Erlwanger (1994), Lamproglena monodi, a gill parasite of several species of cichlids, has Coptodon rendalli (Boulenger, 1897) as one of its preferred hosts. However, in Brazil, L. monodi has been recorded in freshwater environments as both a parasite of O. niloticus and C. rendalli (Azevedo et al, 2010;Azevedo et al, 2012;Tavares-Dias et al, 2015). Such records confirm that O. niloticus has brought along partly or all of its native parasites when introduced in Brazil (Britto & Silva-Souza, 2017).…”

“…As well as representing a direct biological risk for native fish fauna, O. niloticus invasion may also lead to the presence of other organisms, like parasitic species non-natives (Jiménez-García et al, 2001;Azevedo et al, 2012;Bittencourt et al 2014a;Zago et al, 2014;Šimková et al, 2019). Co-introductions include parasitic species, and are a rarely documented risk, particularly in Brazil (Azevedo et al, 2012;Bittencourt et al, 2014a;Zago et al, 2014), as, most of the time, parasite introductions by hosts are neglected. Diseases caused by ectoparasites are variable, and may cause destruction of scales, abundant secretion of mucus, hyperplasia and necrosis of cells (Eiras, 1994).…”

From Africa to Brazil: detection of African Oreochromis niloticus parasites in Brazilian fish farms

Aim To evaluate the introduction of Oreochromis niloticus gill parasites in the Paranapanema River basin, northern Paraná, southern Brazil, as well as to inventory its occurrences in Brazilian fish farms and discuss the risks of transmission to native fauna. Methods The gills of 632 fish specimens from four fish farms in the Paranapanema Basin were analyzed. The parasites were collected, processed and identified according to specific procedure. Literature review was carried out to compile records of occurrence of gill parasites species in other Brazilian river basins. Results A total of seven (7) species of parasites were recorded, five (5) of the genus Cichlidogyrus, one (1) of Scutogyrus (Ancyrocephalidae, Monogenoidea) and one (1) of Lamproglena, Lamproglena monodi (Copepoda, Lernaeidae). All native from Africa. Some of these species have been reported in fish farms located in five other Brazilian watersheds. However, in this study a greater number of African gill parasite species was recorded in fish farms in northern Paraná (seven species), in the Paranapanema Basin, with Cichlidogyrus rognoni reported only for this basin. Conclusions The results confirm the introduction of these African parasites along with their host, O. niloticus, and the establishment of these species in Brazilian waters, since many specimens belonging to the species identified herein presented breeding activity for at least one period of the year. Although, only L. monodi has been recorded parasitizing Brazilian native species, data reported for other countries demonstrates the imminent risk of transmission of these O. niloticus parasites to native cichlids.

“…Parasitological indexes of prevalence (P%), mean intensity of infestation (AII), and mean abundance (AX) were recorded, as described by Bush et al (1997). The identification of the parasites was based on semi-permanent mounts on the Hoyer medium to analyze the morphology and morphometry of sexual apparatus and sclerotized structures, comparing the obtained data with the literature (Douellou, 1993;Ibraheem and Izawa, 2000;Azevedo et al, 2012).…”

Parasites represent a serious obstacle in Brazilian intensive fish farming, and then, monitoring parasitic infestations in aquaculture is a duty of every tilapia producer. The objective of this study was to identify the branchial ectoparasites of Nile tilapia, evaluate the correlation between parasitic intensity, host biometrics, and limnological variables, as well as to identify gill histological changes in fish. Thus, fish representing the three phases (I, II, and III) of production were collected in two commercial fish farms - 1 and 2, necropsied, and their parasites quantified and identified. The gill alterations were processed for histological analysis. Cichlidogyrus sclerosus and Scutogyrus longicornis (Monogenoidea), and Lamproglena monodi (Lernaeidae) have been identified in the tilapia gills. The highest intensities of Monogenoidea infestation were in summer and autumn in both fish farms, with a positive correlation between parasites and water temperature. Infestation by L. monodi occurred only in Fish farm 2, with greater infestations in winter and spring, with a negative correlation between water temperature and parasitism. There was also an increase in parasitism according to the weight and length of the fish in the two fish farms. Histological changes such as hyperplasia, lamellar hypertrophy, and the presence of basophilic cysts on the secondary lamellae were detected in tilapia. Thus, water quality parameters and season of the year, which are closely related, can affect communities of parasites that infest Nile tilapia grown in cages. These findings are important to assist in planning disease control and prevention strategies for Nile tilapia fish farming, to reduce economic losses resulting from fish diseases and death.
