LEVANTAMENTO PARASITOLÓGICO EM Hoplias Malabaricus, Bloch, (1794) (TRAIRA) DE ÁGUAS DA REGIÃO DE SANTA MARIA - RS

Abstract

No presente trabalho estudou-se os parasitos encontrados em 139 traíras coletadas nas diferentes estações do ano em lagoas e açudes do município de Santa Maria, RS. Os objetivos deste levantamento foram: determinar a localização preferencial dos parasites no hospedeiro, relacionar a prevalência dos parasites com as estações do ano e identificar os mesmos a nível de gênero e se possível espécie. Dos 139 peixes necropsiados, 2812 parasites foram coletados ficando assim distribuídos: 469 na primavera, 921 no verão, 482 no outono e 940 no inverno. Destes 2812 parasitos, 1637 foram nematódeos pertencentes as seguintes espécies: Contracaecum sp, Parasseuratum soaresi, Paracappilaria piscicola, Guyanema baudi, Spirocamallanus hilarii, Procamallanus peraccuratus e nematódeos não identificados; 931 trematódeos pertencentes a Ithyoclinostomulum dimorphum, Tylodelphylus sp. 1, Dendrorchis sp, Clinostomum sp e Halipegus overstreeti; 106 acantocéfalos pertencentes a Quadrigyrus machadoi; 138 microcrustáceos do gênero Ergasilus e 20 argulídeos do gênero Dolops.

Morphological aspects of Clinostomidae metacercariae (Trematoda: Digenea) in Hoplerytrinus unitaeniatusand Hoplias malabaricus (Pisces: Erythrinidae) of the Neotropical region, Brazil

“…In Brazil that metacercaria was reported parasitizing the mesentery, musculature, heart, esophagus, cloaca, gills, opercula and fins (Pavanelli et al 1990, Moreira 2000, Rodrigues 2010. In the present study, the prevalence indices were lower than those recorded in H. malabaricus by Pavanelli et al (1990), Weiblen and Brandão (1992), Paraguassú and Luque (2007) and Rodrigues (2010), but the mean intensity of infection was very close to those recorded by Pavanelli et al (1990) (1.53), Weiblen and Brandão (1992)…”

“…Metacercariae of I. dimorphum were reported from H. malabaricus of State of Espírito Santo, (Travassos et al 1964); State of Paraná (Pavanelli et al 1990); State of Rio Grande do Sul (Weiblen and Brandão 1992, Fortes et al 1996, Gallio et al 2007, Rodrigues 2010; State of Rio de Janeiro (Paraguassú and Luque 2007); from H. malabaricus and H. unitaeniatus of State of Minas Gerais (Moreira 2000), Schizodon borelli of High Paraná River Basin (Machado et al 1996). This is the first report of metacercariae of I. dimorphum in Amazonian fish.…”

Digenea of Hoplias intermedius and Hoplias malabaricus (Actinopterygii, Erythrinidae) from upper São Francisco River, Brazil

“…Among trahiras, the prevalence was 14.3% in the Parque de Reserva and Refúgio Soóretama, State of Espírito Santo (calculated value by the authors from one fish parasitized of seven examined by TRAVASSOS et al, 1964); 41.1% in the Paraná River (PAVANELLI et al, 1990), while suggested hematophagy due to the brown pigment noted in the caeca of the parasites; 17.9% in the lakes and dams from Santa Maria, State of Rio Grande do Sul (WEIBLEN & BRANDÃO, 1992); 30.8% in the Lages Reservoir, State of Rio de Janeiro (PARAGUASSÚ & LUQUE, 2007); 42% in the lake of the Cachoeira do Sul municipality (GALLIO et al, 2007); 71.4% (calculated value by the authors, from five parasitized fish of seven examined) of trahiras from Carioca Hosts: Hoplias intermedius (Günther, 1864) and Hoplias malabaricus (Bloch, 1794) (new hosts).…”
