“…Since the fingerlings require more O 2 and due to lack of O 2 they Mean ± SD 27 ± 3.7 6.4 ± 0.5 7.25 ± 0.6 become more prone to infection. High stocking density of fingerlings is another reason for ectoparasitic disease outbreak (Hossain et al 2008). High stocking density increases the chance of ectoparasite transmission from fish to fish easily.…”

“…It is evident from the available literature that parasitic diseases caused significant damage in nursery system of carp mostly affecting the fry and fingerlings (Gopalkrisnan 1961). The parasitic community of fish show considerable variation with the environmental conditions in which fish live (Hossain et al 2008). Certain environmental conditions are more conducive to disease among which water temperature is one of the important criteria associated with disease out break.…”

Resumo -O objetivo deste trabalho foi avaliar a fauna parasitária dos peixes híbridos cachapinta (Pseudoplatystoma corruscans macho x P. reticulatum fêmea) e jundiara (Leiarius marmoratus macho x P. reticulatum fêmea) no período de larvicultura. Um total de 315 animais, 126 híbridos jundiara e 189 híbridos cachapinta, foram examinados de acordo com o estágio de desenvolvimento: larvas, pós-larvas e alevinos. Larvas e pós-larvas foram prensadas entre lâmina e lamínula e observadas sob microscopia óptica. Os alevinos foram observados externamente em estereomicroscópio e necropsiados para avaliação interna dos órgãos. Foram aferidos os parâmetros de qualidade de água em todas as fases de cultivo. O exame parasitológico revelou a presença dos protozoários Epistylis sp. e Trichodina sp., no tegumento e nas brânquias, Ichthyophthirius multifiliis no tegumento, dos helmintos Monogenea nas brânquias, e das metacercárias de digenéticos em brânquias, baço, rins, fígado e intestino, em ambos os híbridos analisados. Os parasitos Epystilis sp., Trichodina sp. e metacercária de digenéticos ocorrem com maior frequência nos dois híbridos, nas fases de pós-larvas e alevinos. Há maior prevalência e diversidade de parasitos na fase de alevinagem dos híbridos estudados.Termos para indexação: Epistylis, Ichthyophthirius multifiliis, Trichodina, bagre, larvicultura, parasitos. Parasitic fauna of the siluriform hybrids cachapinta and jundiara in the first stages of developmentAbstract -The objective of this work was to evaluate the parasitic fauna of the hybrid fish cachapinta (Pseudoplatystoma corruscans male x P. reticulatum female) and jundiara (Leiarius marmoratus male x P. reticulatum female) at the hatchery stages. A total of 315 animals, 126 hybrids of jundiara and 189 hybrids of cachapinta were examined according to their development stage: larvae, post-larvae, and fingerlings. Larvae and post-larvae were pressed between a slide and a cover slip and were observed under optical microscopy. Fingerlings were externally observed in a stereomicroscope and dissected for internal evaluation of organs. Water quality parameters were measured in all cultivation phases. The parasitological exam showed the presence of the protozoa Epistylis sp. and Trichodina sp., on integument and gills, and Ichthyophthirius multifiliis on integument, of the helminth Monogenea on gills, and of digenean metacercariae on gills, spleen, kidneys, liver, and intestines in both hybrid fish evaluated. The parasites Epistylis sp., Trichodina sp., and digenean metacercariae occur most frequently in the two hybrids at the stages of post-larvae and fingerlings. There is a higher prevalence and diversity of parasites in the fingerling phase of the studied hybrids.

“…Members of the family Trichodinidae, they present complex structures on the aboral face, composing the adhesive disk (BASSON; VAN AS, 2006), which presents fast circular movements that can cause abrasive lesion on the host when at high levels of parasitism, even being able to cause mortality (KHAN, 2004). Situations like these usually occur in fish breeding, since changes in the environmental quality directly influence the occurrence of these protozoa (HOSSAIN et al, 2008).…”

Family Trichodinidae comprises ciliate protozoa distributed worldwide; they are considered some of the main parasitological agents infecting cultivated fish. However, the trichodinidae parasitizing important fish species cultured in Brazil are unknown, and more taxonomic studies on this group of parasites are required. This research morphologically characterizes Trichodina colisae Asmat & Sultana, (2005) of pacu (Piaractus mesopotamicus) and patinga hybrid (P. mesopotamicus × P. brachypomus) cultivated in the central and southeast regions of the country. Fresh assemblies were made from mucus scraped from the skin, fins and gills, fixed with methanol and, subsequently, impregnated with silver nitrate and stained with Giemsa for assessment under light microscopy. This research reports not only the second occurrence of T. colisae in the world, but also its first occurrence in South America.
