Abstract

De Araújo, R.S. ; Corrêa, F.; de Sousa, F.B.; Ramos, A.B.M.A.; Neto, J.L.S. & Matos, E.R., (2017). Ocorrência de Myxobolus sp. (MYXOZOA) EM Thoracocharax stellatus (KNER, 1858) (Characiformes) em um Igarapé da Floresta Amazônica, Pará, Brasil. Braz. J. Aquat. Sci. Technol. 18(2). eISSN 1983-9057. DOI: 10.14210/bjast.v21n1. Thoracocharax stellatus (KNER, 1858), belonging to the Gasteropelecidae family, is represented by small fish. The fish were captured using dragnets in an area adjacent to the Guamá River, with an average total length of 4.2±0.8 cm and total average weight of 0.9±0.3 g. Fragments of gills were collected and analyzed fresh under a light microscope, where the presence of cysts full of spores of Myxobolus sp. with unequal polar capsules was observed. This study reports the first record of Myxobolus sp. found in T. stellatus coming from a tropical river in the State of Amazonia, in which the morphological characteristics differ from those of the other species when compared.

Aquat。科学。抛光工艺。18(2)。eISSN 1983 - 9057。DOI: 10.14210 / bjast.v21n1。Thoracocharax stellatus (KNER, 1858)，属拟虾科，以小鱼为代表。采用拖网在瓜马河附近海域捕获，平均全长4.2±0.8 cm，平均总重0.9±0.3 g。在光镜下，我们收集了鳃片，并对其进行了新鲜的分析。在光镜下，我们观察到了充满孢子的囊，这些孢子具有不等极性的蒴果。本文报道了在亚马孙州热带河流中发现的第一个Myxobolus sp.的记录，其形态特征与其他物种相比有所不同。
