Title

REPRODUCTIVE BIOLOGY OF PSEUDOTOCINCLUS TIETENSIS (SILURIFORMES: LORICARIIDAE: HYPOPTOPOMATINAE), A THREATENED FISH SPECIES

Pages

  218-227

Abstract

 Pseudotocinclus tietensis is endemic to the Upper Tietê River basin and classified asvulnerable. The reproductive biology of this species is still unknown, therefore, we investigated itsreproductive strategy and gonad development during its annual REPRODUCTIVE CYCLE. The fish werecollected throughout one year, and histology of the GONADS, FECUNDITY and oocyte diameter wasconducted. Three phases of gonad maturation were found in males and females (immature, developing, and spawning capable), and the development stages of the gametes were identified withineach stage. In the testes, four stages of gamete development were distinguished: spermatogonia, spermatocytes, spermatids and spermatozoa. During spermiation, the spermatozoa were released intothe tubular lumen and then continued through the efferent ducts. In the ovaries, five stages of gametedevelopment were identified: chromatin nuclear, perinucleolar, yolk vesicle formation, vitellogenicand ripe. The minimum diameter of ovulating oocytes was 297 μm, and the absolute FECUNDITY was64 to 306 oocytes. Males with spermatozoa in the lobular lumen and females with vitellogenic andripe oocytes were found throughout the year. PSEUDOTOCINCLUS TIETENSIS has asynchronous ovariandevelopment and gametes with fertilization capacity can be eliminated throughout the annual cycle.
