Ichthyofauna of Mundaú river basin, Ceará State, Northeastern Brazil

Abstract

Mundaú river basin is located at Center-North Ceará State and occupies a total area of 2,227 km2, including Estuário do Rio Mundaú Environmental Protection Area. This study aimed to catalog the fishes of this basin. Collections were performed with active and passive gear in 35 sampling sites, between 2012 and 2014, in several habitats (main channels, streams, floodplains, permanent and temporary pools, ponds, and dams). A total of 2,545 specimens were collected, belonging to 55 species distributed in 10 orders, 31 families, and 50 genera; 30 of these are strictly freshwater species, and 25 estuarine-marine species. Three species (Hemigrammus guyanensis Gery, 1995, H. rodwayi Durbin, 1909 and Poecilia sarrafae Bragança & Costa, 2011) represent new records for the Mid-Northeastern Caatinga ecoregion. Besides, two cynolebiid species, Hypsolebias sp. and Anablepsoides cearensis (Costa & Vono, 2009), were found and the latter, currently classified as critically endangered, had its occurrence area widened.

Ichthyofauna of the Reserva Biológica Guaribas and surrounding areas, state of Paraíba, Brazil

“…Hemigrammus rodwayi has been reported for streams in Guiana, Suriname, French Guiana and the Amazon basin (Reis et al 2003, Buckup et al 2007) with few reported records for the northeastern Brazil (Teixeira et al 2017).…”

Continental ichthyofauna from the Paraíba do Norte River basin pre-transposition of the São Francisco River, Northeastern Brazil

“…This paradigm has recently changed with the publication of a book chapter entitled "Diversity, patterns of distribution and conservation of fishes from Caatinga" in Rosa et al (2003) listed 240 species of freshwater fishes for the Caatinga biome, comprising the broadest evaluation about the freshwater ichthyofauna from this region to date. Various studies have since been undertaken which the understanding of the regional ichthyofauna through publications, including: Ramos et al (2005), Alves et al (2008), Nascimento et al (2011), Cardoso (2012), Gurgel-Lourenço et al (2013), Novaes et al (2013, Camelier & Zanata (2014), Nascimento et al (2014), Paiva et al (2014), Silva et al (2014), Ramos et al (2014), Silva et al (2015), Gurgel-Lourenço et al (2015), Rodrigues-Filho et al (2016), Costa et al (2017), Teixeira et al (2017) and Oliveira-Silva et al (2018).…”

Geographic distribution and conservation of seasonal killifishes (Cyprinodontiformes, Rivulidae) from the Mid-Northeastern Caatinga ecoregion, northeastern Brazil

“…A detailed integrative analysis using both molecular and morphological data, including more specimens, especially males, may confirm the identity of the species from the Mundaú river basin. Moreover, the occurrence of the critically endangered non-annual rivulid, Anablepsoides cearensis (Costa & Vono, 2009) in the coastal plains of this basin (Teixeira et al 2017, ICMBio 2018 corroborates it as an extremely high priority area for the Caatinga's fish conservation (MMA 2018).…”
