“…Other trichodinids like T. reticulata and T. nobilis were observed to be parasitizing several ornamental fish species including C. auratus ; Trichodinids such as T. acuta in X. helleri, X. maculatus, P. sphenops, B. splendens were previously reported (Piazza et al, 2006). The present study showed a higher prevalence of trichodinids than that found by Thilakaratne et al (2003), Piazza et al Martins et al (2012), Kayis et al (2013) and Marques et al (2015). In fish farm Biguaçu, D. rerio presented mortality outbreaks caused by trichodinids in pond-reared fish, but the fish farmer did not quantify both the amount of dead fish and financial losses.…”

ABSTRACT. The ornamental fish aquaculture represents a consolidated market worldwide. In Brazil, the major volume of commercialized freshwater ornamental fish is originated from fish farms managed by small and midsized farmers. The aim of this study was to characterize the metazoan parasitic fauna associated with the main freshwater ornamental fish farmed in Southern Brazil. Between July 2014 and January 2015, 423 fishes belonging to nine freshwater species were examined: angelfish Pterophylum scalare, siamese fighting fish Betta splendens, telescope and comet goldfish Carassius auratus, zebrafish Danio rerio, blood red swordtail Xiphophorus helleri, caramel and wagtail platy fish Xiphophorus maculatus, black molly Poecilia sphenops, white cloud mountain minnow Tanichthys albonubes and goldfinned barb Puntius sachsii. Water quality was measured in fishponds from each facility. Specimens were obtained from three ornamental fish farms located in three micro-regions in the State of Santa Catarina (Biguaçu, Camboriú e Joinville). Parasitological indexes were obtained after parasitological analysis of mucus, gills, and eyes. Trichodinids, Piscinoodinium pillulare, and Ichthyophthirius multifiliis were found in all fish farms analyzed. However, P. pillulare showed the greatest prevalence and mean intensity, compared to the other protozoa analyzed. 75% prevalence and mean intensity 57.5 were observed in the gills of P. scalare from fish farm Araquari. This study showed that fish farm Biguaçu, was the facility presenting the greatest parasite diversity. P. scalare and C. auratus were the most parasitized fish species presenting the higher richness when compared to another species. These ornamental species are widely traded and require greater care in cultivation because it is essential to produce healthy fish with attractive features accepted by the market.

“…Until 2006 trichodinids from farmed fishes in Brazil were recognized only at their generic level. From that year on, several studies have been performed in order to identify trichodinids at specific level (GHIRALDELLI et al, 2006;PINTO et al, 2009;JERÔNIMO et al, 2011;MARTINS et al, 2010a;MARTINS et al, 2012;MIRANDA et al, 2012;PÁDUA et al, 2012c).…”

The Phylum Protozoa brings together several organisms evolutionarily different that may act as ecto or endoparasites of fishes over the world being responsible for diseases, which, in turn, may lead to economical and social impacts in different countries. Apart from the recent advances for the diagnosis of fish diseases in Brazil, little is known on the protozoan parasites and their relationship with environment and host. This revision presents the most important protozoan parasites found in farmed fish from Brazil, not only with emphasis on its diagnosis, biology, transmission and host-parasite relationship, but also on some information that may be useful to researchers in determining the correct diagnosis in fish farms.Keywords: Fish parasites, disease, ciliate, dinoflagellate, pathogenicity. ResumoO filo Protozoa reúne diversos organismos evolutivamente distintos que podem atuar como ecto ou endoparasitos de peixes em todo o mundo, sendo responsáveis por doenças as quais, por sua vez, podem ocasionar impactos econômico e social nos diferentes países. Apesar dos recentes avanços no campo de diagnóstico de doenças em peixes no Brasil, ainda pouco se conhece sobre a fauna de protozoários parasitos de peixes e suas relações com o ambiente e hospedeiro. Esta revisão apresenta os mais importantes protozoários parasitos encontrados em peixes cultivados no Brasil, não apenas com ênfase no seu diagnóstico, biologia, transmissão e relação hospedeiro-parasito, mas também algumas informações que podem ser úteis para pesquisadores para o correto diagnóstico em pisciculturas.Palavras-chave: Parasitos de peixes, enfermidade, ciliado, dinoflagelado, patogenicidade.

During a survey of trichodinids in Chongqing, China, two populations of Trichodina reticulata Hirschmann & Partsch, 1955 were isolated from gills of the freshwater fishes, Carassius auratus and Ctenopharyngodon idellus, and 11 molecular samples containing small subunit (SSU) rDNA and internal transcribed spacer (ITS)-5.8S rDNA were newly sequenced. Both populations fell within the range of morphometry and corresponded well with the diagnostic morphological features of Trichodina reticulata Hirschmann & Partsch, 1955. It should be noted that one population possessed obvious central granules in the adhesive disc, while the other one did not. The detailed morphological redescription for these two populations is given in this work. Although some intraspecific differences were found, both populations were confirmed as Trichodina reticulata based on the morphological study and molecular data, including the sequence analysis of the primary and secondary structures of SSU rDNA, genetic distances and phylogenetic tree. Our study supports the assertion that central granules in the adhesive disc might be an auxiliary feature rather than a heritable character for determining taxonomic affiliations among trichodinids.
