“…In P. braueri and P. pardalis, Shannon diversity, equitability and species richness of parasites were low. In host fish populations, parasite diversity and richness depend directly on the population dynamics of birth, death, migration, age and diet of the host, presence of infective forms, environment quality, seasonality and geographical factors, among other biotic and abiotic factors (Luque et al 2013;Hoshino and Tavares-Dias 2014;Tavares-Dias et al 2014).…”

This study investigated the metazoan parasite fauna in Peckoltia braueri and Pterygoplichthys pardalis from a tributary of the Amazon River system, in northern Brazil. In P. braueri, 630 parasites were collected, belonging to Unilatus unilatus, Nothogyrodactylus sp., Genarchella genarchella, Proteocephalus sp., Gorytocephalus elongorchis, Dolops longicauda and Hirudinea gen. sp., with a dominance of monogenean species. In P. pardalis, 120 parasites were collected, belonging to U. unilatus, Acanthostomum gnerii and Gorytocephalus elongorchis, and this acanthocephalan was the dominant species. In both hosts, the parasites presented clumped distribution, high prevalence, low abundance, low Shannon diversity, and low species richness, with a predominance of helminth species. In P. braueri, host length was positively correlated with parasite species richness and Shannon index. There was no difference in the body condition of parasitized and non-parasitized fishes in either host. This was the first report of these parasites in P. braueri and P. pardalis.

Fauna de metazoários parasitando Peckoltia braueri e Pterygoplichthys pardalis (Loricariidae), bagres do nordeste da Amazônia brasileira RESUMOEste estudo investigou a fauna de parasitos metazoários em Peckoltia braueri e Pterygoplichthys pardalis de um tributário do sistema do Rio Amazonas, no Amapá, norte do Brasil. Em P. braueri foram coletados 630 parasitos das espécies Unilatus unilatus, Nothogyrodactylus sp., Genarchella genarchella, Proteocephalus sp., Gorytocephalus elongorchis, Dolops longicauda e Hirudinea gen. sp., com dominância das espécies de monogenoideas. Em P. pardalis foram coletados 120 parasitos das espécies U. unilatus, Acanthostomum gnerii e Gorytocephalus elongorchis, sendo este acantocéfalo a espécie dominante. Os parasitos em ambos hospedeiros apresentaram dispersão agregada, elevada prevalência, baixa abundância, baixa diversidade de Shannon e baixa riqueza de espécies, com predominância de espécies de helmintos. Em P. braueri, o comprimento dos hospedeiros apresentou correlação positiva com a riqueza de espécies de parasitos e o índice de Shannon. Não houve diferença entre a condição corporal de peixes parasitados e não parasitados para os dois hospedeiros. Este foi o primeiro relato desses parasitos para P. braueri e P. pardalis.

Summary This study investigated the influence of the rainy and dry seasons on the parasite communities of Cichlasoma amazonarum (Kullander, 1983) in a tributary of the Amazon River system, northern Brazil. Of 112 fish examined, 95.5% were parasitized by Ichthyophthirius multifiliis, Piscinoodinium pillulare, Gussevia disparoides, Posthodiplostomum sp., Procamallanus (Spirocamallanus) inopinatus, and Echinorhynchus paranensis, as well as by the Glossiphoniidae leech. Ichthyophthirius multifiliis and P. pillulare were the dominant parasite species, with I. multifiliis the most prevalent and abundant; the leech (Glossiphoniidae) was the least prevalent and least abundant. Parasites presented an aggregate dispersion pattern and seasonal variations in infestation levels, influenced by the environmental conditions in the rainy season. Variation in the parasite dynamics created overall changes in the parasite communities, characterized by greater diversity, species richness and evenness during the rainy season. However, there was a high similarity (99.8%) in the parasite community structure between the rainy and dry seasons. During the dry season the hosts had predominantly 1–3 parasite species compared to 3–4 parasites in the rainy season. Some parasites in the eastern Amazon undergo population changes relating to seasonality. These results thus indicate the correct season to apply adequate prophylactic measures to reduce negative impacts of parasites in this wild ornamental fish when captured.

Metynnis lippincottianus is a freshwater native fish to the Guiana basin and Amazon basin and was recently introduced into the São Francisco River in Brazil. This study aimed to determine the helminths parasites of M. lippincottianus from the Três Marias Reservoir, upper São Francisco River, State of Minas Gerais, Southeast Brazil. From 67 hosts examined, 63 were parasitized by 9,257 helminths represented by five species: Dadayius sp. [prevalence (P) = 1.49%, mean abundance (MA) = 0.01]; proteocephalid plerocercoids (P = 43.28%, MA = 5.04); Procamallanus (Spirocamallanus) inopinatus (P = 29.85%, MA = 0.54); Spinitectus rodolphiheringi (P = 2.99%, MA = 0.03); Spinoxyuris sp. (P = 85.07%, MA = 132.54). These findings show that M. lippincottianus is an additional host to the helminths infecting fish native to the São Francisco River (plerocercoids, P. (S.) inopinatus and S. rodolphiheringi), and highlight the fact that Dadayius sp. and Spinoxyuris sp., which were typically found in native Metynnis spp. in other basins, also parasitizing the non-native serrasalmid M. lippincottianus in São Francisco River. These two helminth species have thrived in this freshwater ecosystem with the expansion of the geographical distribution of the host species to the São Francisco River.
