Abstract

BARBIERI, Geraldo. Reproduction dynamics of Rineloricaria latirostris Boulenger (Siluriformes, Loricariidae) of the Passa Cinco River, Ipeúna, São Paulo. Rev. Bras. Zool. [online]. 1994, vol.11, n.4, pp. 605-615. ISSN 0101-8175.  http://dx.doi.org/10.1590/S0101-81751994000400003.

Aspects of reproduction of Rineloricaria latirostris Boulenger, 1899 of Passa Cinco river (Ipeúna, São Paulo) were investigated during 18 months. The spawing period was determined by the analysis of the maturation curve, based of the monthly variation of the gonadosomatic index and condition factor. The size and age on the maturation and fecundity were also determined. The fecundity was realted to some parameters such as total length and total weight.

Keywords : Reproduction; dynamics; maturation; fecundity.
