DNA barcoding is a useful complementary tool for use in traditional taxonomic studies due to its ability detect cryptic species, and may be particularly efficient the identification of fish species. The fauna Itapecuru River represents an important fishery resource Brazilian State Maranhão, although it currently suffering increasing degradation as result anthropogenic impacts. Therefore, was used present study identify species establish database rich freshwater Maranhão. A total 440...
Uncertainty regarding the age determination of Brazilian codling Urophycis brasiliensis has hampered its stock assessment. Transverse sections otoliths displayed up to seven (in males) and 12 females) alternate opaque translucent bands that could not be conclusively validated as annuli, resulting in unrealistically high ages first maturity ( A 50 ) 50male = 4·5 years 50female 6 years). Therefore, growth was described by von Bertalanffy (VB) model using an alternative approach combined...
Abstract The “piaussu”, Megaleporinus macrocephalus is an anostomatid fish species native to the basin of Paraguay River, in Pantanal biome western Brazil. However, this has now been recorded a number other drainages, including those upper Paraná, Uruguay, Jacuí, Doce, Mucuri, and Paraíba do Sulrivers. This study presents two new records occurrence M. macrocephalus, basins Itapecuru Mearim rivers state Maranhão, Brazilian Northeast. piaussu large-bodied commercial interest that widely raised...
Astyanax bimaculatus are small characids known as piabas or lambaris that form a complex encompassing 18 species, including cryptic species. The present study aimed to use DNA barcode analyze populations of A. found in Maranhão hydrographic basins, comparing molecular diversity indices between from the other Brazilian basins. results revealed formation 32 haplotypes (h = 0.9289; π 0.0523). Seven haplogroups were formed with intrapopulation genetic distance ranging 0 2%. Western Northeast...
Abstract The Baixada Maranhense Environmental Protection Area of the Brazilian state Maranhão encompasses a biologically rich region that includes basins four principal rivers, Mearim, Pericumã, Pindaré, and Turiaçu, which form complex wetlands. present study provides comprehensive inventory fish fauna rivers drain based on identification voucher specimens were deposited in scientific collection. Expeditions conducted between 2014 2020. identified total 100 species representing 79 genera, 34...
