“…The prevalence of this species in the mouth, gills, and nasal cavity of C. macropomum has been reported to be of 95%, in fish farmed in Manaus, in the state of Amazonas (Benetton & Malta, 1999). Heavy infestation of this parasite in young fish causes mortality and economic losses (Godoi et al, 2012).…”

-The objective of this work was to evaluate the parasitic fauna of hybrid tambacu (Colossoma macropomum x Piaractus mesopotamicus) from fish farms and the host-parasite relationship. A hundred and fourteen fish were collected from four fish farms in Macapá, in the state of Amapá, Brazil, 80.7% of which were infected by: Ichthyophthirius multifiliis (Ciliophora); Piscinoodinium pillulare (Dinoflagellida); Anacanthorus spatulatus, Notozothecium janauachensis, and Mymarothecium viatorum (Monogenoidea); Neoechinorhynchus buttnerae (Acanthocephala); Cucullanus colossomi (Nematoda); Perulernaea gamitanae (Lernaeidae); and Proteocephalidae larvae (Cestoda). A total of 8,136,252 parasites were collected from the examined fish. This is the first record of N. buttnerae, C. colossomi, N. janauachensis, M. viatorum, and Proteocephalidae for hybrid tambacu in Brazil. Ichthyophthirius multifiliis was the most prevalent parasite, whereas endohelminths were the less. A positive correlation was observed between number of I. multifiliis and total length and weight of fish, as well as between number of P. gamitanae and total length. The infection by I. multifiliis had association with the parasitism by Monogenoidea. Low water quality contributes to high parasitism of hybrid tambacu by ectoparasites, which, however, does not influence the relative condition factor of fish.Index terms: Colossoma macropomum, Ichthyophthirius multifiliis, Piaractus mesopotamicus, ectoparasite, native fish, host-parasite relationship.

The matrinxã, Brycon amazonicus, is one of the main species being used for aquaculture and fishery activities in the Amazonian region, yet little is known about the parasites that cause its diseases. The present study monitored parasite fauna infesting an intensive husbandry system in a stream channel. The collections were carried out monthly from September, 1997 to January, 1998. Water quality parameters, fish removal procedures, as well as biometry and anaesthetic data were observed in order to monitor the management conditions. Of the 80 sampled fish, 71 (89%) were infested with four Monogenoidea species (Anacanthorus spiralocirrus, Jainus amazonensis, Tereancistrum kerri and Trinibaculum brazilensis), 12 (15%) one of Nematoda Spirocamallanus inopinatus, and three (3.75%) with the Copepoda Ergasilus bryconis. Monogenoidea presented the highest prevalence and intensity of infestation. The KruskallWallis non-parametric variance analysis showed a significant difference (P < 0.05) in the monthly parasite indexes of A. spiralocirrus, J. amazonensis and T. brazilensis, however no significant difference (P ≥ 0.05) was detected for T. kerri. Evaluation of the management conditions pointed out that monthly capture anaesthesia and hauling procedures may have been responsible for some of the clinical signals such as loss of scales, erosion and no pigments on the caudal fin and cornea opacity, which were the most frequently found injuries in husbandry.

“…However, some infestations seriously compromise the performance and growth of cultured fish. The main parasites recorded for tambaqui are: the monogeneans Anacanthorus spathulatus Kritsky, Thatcher & Kayton 1979, A. (Fischer et al 2003) and Perulernaea gamitanae Thatcher &Paredes 1985 (Benetton andMalta 1999); the myxosporidean Henneguya piaractus Martins & Souza 1997, and the ciliated protozoan Ichthyophthirius multifiliis Fouquet 1876.…”

Parasite-host relationship between the tambaqui (Colossoma macropomum Cuvier 1818) and ectoparasites, collected from fish farms in the city of Rolim de Moura, State of Rondônia, Western Amazon, Brazil

In this study we investigated the relationship between tambaqui fish (Colossoma macropomum Cuvier 1818) and parasites in two fish farms (L204S and L180N) in the state of Rondônia, Brazil, during a 1-year period. The objective of the study was to describe the relationships between parasites, hosts and the environment. From the 80 fish specimens collected, 100% were parasitized by at least one parasite species. Seven ectoparasites species were recorded, six of the class Monogenea: Anacanthorus spathulatus, Mymarothecium spp. (Mymarothecium sp. 1, Mymarothecium sp. 2 and M. viatorum), Notozothecium sp. and Linguadactyloides brinkimanni, classified as dominants, and the copepod Perulernaea gamitanae, classified as subordinate. Despite their high prevalence, the parasites were not abundant. A. spathulatus presented positive and significant correlations between the abundance of parasitism and the standard length of the hosts in the two fish farms; Mymarothecium spp. showed significant correlations, negative in L180N, and positive in L204S; significant positive correlations were observed for Notozothecium sp. in L204S, and for L.brinkimanni in L180N. Young monogeneans were found; these parasites presented a negative correlation in L180N and a significant negative correlation in L204S. The results of the correlation between the relative condition factor (Kn) and the abundance of parasites were not significant for the recorded parasite species. Regarding the hepatosomatic relation (HSR) of fish and the abundance of parasites, Anacanthorus spathulatus showed a significant negative correlation with the HSR in L180N, and a positive correlation in L204S. Mymarothecium spp. and Notozothecium sp. presented significant positive correlations in L204S. Considering the correlation of the fish splenosomatic relation (SSR) and the abundance of parasites, L. brinkimanni presented significant correlations, positive in L180N and negative in L204S. Despite 100% prevalence, the high water quality contributes to infracommunities with low parasite abundance and good levels of Kn, HSR and SSR, allowing good tambaqui development.
