Zusammenfassung:Figs 10, 11. Histological sections of gonads of Characidium pterostictum Gomes, 1947 specimens collected in upper Sinos river, RS, between January and December 2007 (3 μm thick sections, staining through PAS + ferric hematoxylin + Metanil Yellow). Figure "9" = spawning capable ovary, with predominance of tertiary yolky oocytes (O3) among some pre-vitellogenic oocytes (Op). Figure "10" = spawning capable testes showing many spermatozoa (Sz) in the lumen and few sperm cysts (C).
