The length-weight relationship was isometric for both the sexes. The length structure analysis showed that the larger individuals (from 18.1cm to 27.0cm in length) predominated, and the lowest abundances occurred at the size extremes (9.1-12cm and 27.1- 30.0cm). The reproduction period occured between October and January for the females and between November and January for the males. The liver somatic index cannot be used as an indicator of the reproduction period in either of the sexes, due to no correlation between the liver somatic index and the gonad somatic index. The gonad weight exerted no influence on the monthly mean condition factor and the correlation between the condition factor and gonad somatic index was high. The condition factor could be an indicator of the reproduction period of this species.

Aprobado: Marzo 15 de 2011 RESUMEN La fecundidad en peces, es la estimación de la cantidad de ovocitos que una hembra podría expulsar en un desove, siendo uno de los indicadores más utilizados para evaluar el potencial reproductivo de una especie y sus posibilidades para la piscicultura. Para aportar al conocimiento de este criterio, se estudiaron los ovarios de hembras silvestres maduras, las cuales fueron pesadas individualmente al igual que sus ovarios y calculado el Índice gonadosómatico (IGS). Luego cada ovario fue digerido en solución Gilson durante 20 días y luego tamizado en malla de 500 µm y los ovocitos retenidos fueron contados y obtenida la fecundidad. -
Scientific Note a Cave Population of Isbrueckerichthys Alipionis (Gosline, 1947) in the Upper Ribeira Karst Area, Southeastern B
Neotropical Ichthyology, 6(4):679-682, 2008 Copyright © 2008 Sociedade Brasileira de Ictiologia Scientific Note A cave population of Isbrueckerichthys alipionis (Gosline, 1947) in the Upper Ribeira karst area, southeastern Brazil (Siluriformes: Loricariidae) Eleonora Trajano1, Sandro Secutti1, Edson H. L. Pereira2 and Roberto E. Reis2 A cave population of the armored catfish Isbrueckerichthys alipionis is reported from the Santana Cave, in the rio Betari wa- tershed, Upper Ribeira karst area, Iporanga, São Paulo State, southeastern Brazil. The cave population was compared to an epigean population of I. alipionis and no significant differences where found in morphology or degree of pigmentation. As the cave population is known for at least 30 years and is apparently isolated from epigean streams, it is classified as troglophilic. The discovery of this troglophilic species in the Santana Cave is an additional strong argument for the conservation of that cave. Uma população cavernícola do cascudo Isbrueckerichthys alipionis é registrada na Caverna Santana, na bacia do rio Betari, na área cárstica do Alto Ribeira, Iporanga, São Paulo, Brasil. A população cavernícola foi comparada com uma população epígea de I. alipionis e nenhuma diferença significativa foi encontrada em morfologia ou grau de pigmentação. Como a população cavernícola é conhecida há pelo menos 30 anos e aparentemente está isolada de cursos d’água epígeos, ela é classificada como troglófila. A descoberta dessa espécie troglofílica na Caverna Santana é um forte argumento adicional para a conservação dessa caverna.

P. cordiformis is proposed Valenciennes, 1840 (Loricariidae: Hypostominae) for specimens with the following features: a heart-like inhabits the basins of the Parana and Uruguay rivers body form, pharynx disproportionately larger, testes in Argentina, Brazil, Paraguay and Uruguay (Ferraris, more anteriorly located, ovary and anterior testis with 2007). For the genus Rhinelepis Agassiz, 1829 only overlapping fields, vitellaria less extended in relation to body length and with fields not confluent posteriorly, another species is considered valid, Rhinelepis aspera and eggs wider than those described for P.
