| Parasitic and infectious diseases are common in finfish, but are difficult to accurately estimate the economic impacts on the production in a country with large dimensions like Brazil. The aim of this study was to estimate the costs caused by economic losses of finfish due to mortality by diseases in Brazil. A model for estimating the costs related to parasitic and bacterial diseases in farmed fish and an estimative of these economic impacts are presented. We used official data of production and mortality of finfish for rough estimation of economic losses. The losses herein presented are related to direct and indirect economic costs for freshwater farmed fish, which were estimated in US$ 84 million per year. Finally, it was possible to establish by the... |

| In vivo and in vitro antiparasitic activity of the essential oil of Lippia sidoides and blood and histological alterations were assessed in Colossoma macropomum (tambaqui). Essential oil concentrations of 10, 20, 40, 80, 160 and 320 mg/L were assayed in vitro against monogenoideans Anacanthorus spathulatus, Notozothecium janauachensis and Mymarothecium boegeri from fish gills. Lippia sidoides essential oil concentrations of 320 and 160 mg/L were 100% effective against monogenoideans in 10 min and 1 h of exposure, respectively. However, the effectiveness of 100% concentrations of 80 mg/L and 40 mg/L occurred in 3 and 6 h, respectively. In the in vivo tests, juvenile fish were submitted to 60 min of baths with 10 mg/L and 15 min of baths with 20 mg/L of the... |

| This study examined the in vitro and in vivo, histopathological, anti-parasitic and hematopathological effects of the essential oil of Lippia origanoides on Colossoma macropomum. Essential oil concentrations of 10, 20, 40, 80, 160 and 320 mg·L-1 were tested in vitro against monogenoideans (Anacanthorus spathulatus, Notozothecium janauachensis and Mymarothecium boegeri) from the gills of C. macropomum. Concentrations of 320 and 160 mg·L-1 were 100% effective against these parasites within 20 and 60 min of exposure, respectively. The 80 mg·L-1 concentration was approximately 80% effective with 3 h of exposure, reaching 100% with 6 h of exposure. The 40 mg·L-1 concentration was also 100% effective with 6 h of exposure. The other concentrations were only... |

| This paper describes the first study on parasite diversity in Auchenipterus nuchalis Spix & Agassiz, 1829 (Auchenipteridae). In 31 fish caught in a tributary of the Amazon River, 10,708 parasites were collected, such as Ichthyophthirius multifiliis, Piscinoodinium pilullare, Cosmetocleithrum striatuli, metacercariae of Posthodiplostomum sp, and larvae and adults of Procamallanus (Spirocamallanus) inopinatus. These parasite species showed aggregated dispersion, except for C. striatuli, which had a uniform dispersion. The component community of parasites showed a low Brillouin diversity (0.67 ± 0.27), low species richness (3.5 ± 0.8) and low evenness (0.43 ± 0.17), and it was characterized by the presence of species with high prevalence and abundance.... |

| Hoplias malabaricus and Hoplerythrinus unitaeniatus are Erythrinidae family widely distributed in the Amazon River system of great value to both commercial and subsistence fi shing for riverine populations. As such, the objective of the present study was to investigate the endoparasite communities of H. malabaricus and H. unitaeniatus of a tributary of the Amazon River in the north of Brazil. The endoparasite communities of H. unitaeniatus and H. malabaricus were taxonomically similar (85%) and consisted of Clinostomum marginatum, Contracaecum sp., Guyanema seriei seriei, Procamallanus (Spirocamallanus) inopinatus, Pseudoproleptus sp. and Gorytocephalus spectabilis, although the dominant endoparasite was C. marginatum, which was the most prevalent and... |

| This study investigated the parasitic fauna of Cichlasoma bimaculatum of a tributary from the Amazon River system, northern Brazil. The prevalence of infection was 94.6 % and, in total, 428 267 parasites, such as Ichthyophthirius multifiliis, Piscinoodinium pillulare (Protozoa), Gussevia arilla (Monogenoidea), Posthodiplostomum sp. (Digenea) and Procamallanus (Spirocamallanus) inopinatus (Nematoda) were collected. However, the dominance was mainly of I. multifiliis, while P. (S.) inopinatus was the parasite species with the lower levels of prevalence and abundance of infection. These parasite species showed an aggregated dispersion pattern. The parasitic fauna was characterized by the presence of few species of parasites with high prevalence and abundance,... |

| This study presents the first report of infection by Linguadactyloides brinkmanni Thatcher & Krytsky, 1983 (Monogenoidea, Dactylogyridae, Linguadactyloidinae) on the gills of hybrid tambatinga (Colossoma macropomum x Piaractus brachypomus) from fish farms from the city of Macapá, state of Amapá, Brazil. Out of 201 hybrid tambatinga examined, ten were infected by L. brinkmanni (prevalence= 4.9%). From these hosts, 21 specimens of L. brinkmanni were collected and the mean intensity of infection was 2.1 (1-4 parasites/host). This study expands the distribution of this monogenoidean for a new host. |

| 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... |

| Assessment of biodiversity is fundamental for the understanding of ecological interactions, but fish parasites were neglected in biodiversity estimates for a long time. The aim of this paper was to investigate the diversity of parasites in Satanoperca jurupari in the Amazon River system in Brazil. Of the fish examined, 90.0% were parasitized by one or more species of protozoans and metazoans, and a total of 3,110,094 parasites were collected. Ichthyophthirius multifiliis, Piscinoodinium pillulare, Sciadicleithum juruparii, Clinostomum marginatum, Posthodiplostomum sp., Genarchella genarchella, Argulus multicolor and Ergasilus coatiarus were found. However, I. multifiliis and P. pillulare were the most prevalent, abundant and dominant parasites, while A.... |

| Na Amazônia brasileira, as pesquisas sobre parasitoides de Tephritidae avançaram nos anos recentes. Estão assinaladas nove espécies de Braconidae (duas não formalmente descritas), sendo Doryctobracon areolatus (Szépligeti) e Opius bellus Gahan as mais abundantes e amplamente distribuídas. Entre os Figitidae, ocorrem quatro espécies, com predomínio de Aganaspis pelleranoi (Brèthes). Algumas espécies vegetais apresentam potencial como "multiplicadoras de parasitoides", como Spondias mombin (Anacardiaceae) e Bellucia egensis (Melastomataceae), com índices de parasitismo de até 50% dos pupários. Bellucia grossularioides (Melastomataceae) apresenta parasitismo de até 20%, porém torna-se relevante em função de sua elevada abundância e ampla distribuição.... |
