Rapid survey of ichthyofauna from rivers and streams of coastal hydrographic regions of Santa Catarina state, Brazil

Abstract

The lack of knowledge on the distribution and taxonomy of ichthyofauna from coastal Atlantic Rainforest of Santa Catarina state, Brazil, is noteworthy. This study presents a rapid but comprehensive survey of fish species from the coastal hydrographic regions of Santa Catarina. The samples were conducted in October 2012, in 19 sampling sites of five hydrographic regions, using sieves, seine nets, and throw nets. A total of 1,878 individuals belonging to 51 species distributed in 16 families are reported; four freshwater fish species represent distribution novelties for the region. The families Characidae and Loricariidae were predominant, mainly due to the abundance of Astyanax sp., Mimagoniates microlepis, Epactionotus itaimbezinho, and Pareiorhaphis stomias. Therefore, this study provides important contributions to the knowledge of the freshwater fishes from the studied area.

Lista De Especies De Peces De La Cuenca Del Río Queguay, Río Uruguay Bajo

“…La riqueza de especies reportada en este trabajo para la cuenca del Río Queguay representa el 42% de las especies reportadas para la eco-región Uruguay bajo (Albert et al, 2011) y sigue el patrón general descrito para la región Neotropical, con el predominio de las especies de los órdenes Characiformes y Siluriformes, y de las familias Characidae, Loricariidae y Cichlidae (Langeani et al, 2005;Cassati et al, 2009;Abrahão et al, 2015). La composición de especies encontrada fue similar a la del mayor afluente de la ecorregión Uruguay bajo, la cuenca del Río Negro (Serra et al, 2014).…”

Ficha de Epactionotus itaimbezinho

“…Dentes acessórios localizados mais internamente e ligados ao osso dérmico formando posteriormente (em pré-maxila) e anterior (no dentário) margens de dentes, que encerram a principal série de dentes bífidos emergentes e pré-emergentes. Dentes acessórios alongados, nitidamente apontados, dirigidos em posição ventral posterior (no pré-maxila) e ventral anterior (no dentário) (Reis & Schaefer, 1998 (Reis & Schaefer, 1998;Abrahão et al, 2015;Delapieve et al, 2020).…”

Ficha de Pareiorhaphis nudula

“…Endêmica do Brasil: Sim Pareiorhaphis nudula é endêmica do Brasil e conhecida das bacias dos rios Araranguá, Mampituba, Tubarão, Três Forquilhas e rio Maquiné, nos estados de Santa Catarina e Rio Grande do Sul (Reis & Pereira, 1999;Weber, 2003;Ferraris Jr., 2007;Abrahão et al, 2015;Bertaco et al, 2016).…”
