Catathyridium garmani (Jordan &amp;amp; Goss, 1889) é registrada pela primeira vez para o litoral nordeste do Brasil com base em 26 exemplares coletados no estuário do rio Paraguaçu, município de São Félix, estado da Bahia. Amplia-se desta forma o limite setentrional da espécie que até o momento restringia-se ao estado do Rio de Janeiro. São ainda apresentados dados morfométricos e meristícos dos exemplares coletados.

Population structure of two Astyanax Baird &amp;amp; Girard, 1854 (Teleostei, Characidae) species from upper Paraguaçu river
Provedor de dados: 52
Autores: Santos,Alexandre Clistenes de Alcântara; Novaes,José Luís Costa.
The fishes of the family Characidae are among the main species of fresh water fishes in South America. In this work, some aspects of the population structure of two Astyanax species were assessed. The fishes were caught in Santo Antônio and São José rivers, in the Paraguaçu basin, by standardized monthly samplings adapted to the microhabitats. Astyanax sp. b (São José river) presented larger size than Astyanax sp. a (Santo Antônio river). The length-weight relationship showed positive allometric growth for Astyanax sp. a, and negative for Astyanax sp. b. Both the species showed a long reproductive period, with higher activities in dry period.

Composition and seasonal variation of the ichthyofauna from upper Rio Paraguaçu (Chapada Diamantina, Bahia, Brazil)
Provedor de dados: 52
Autores: Santos,Alexandre Clistenes de Alcântara; Caramaschi,Érica Pellegrini.
The aim of this work was to characterize the composition of the ichthyofauna of the upper course of the Rio Paraguaçu. Two excursions were carried out, one in the dry season, and the other in the rainy season, with 36 localities sampled. A total of 63 species were collected. Multivariate analyses indicated that abiotic variables such as the channel order and altitude were the main influences on the number of species present. The number of species in each excursion was equivalent in the two seasons, suggesting that seasonal changes have little influence on the ichthyofauna of this area.
