Weight Relationship

This work presents the length-weight relationships of 14 species of fish of the Napo River basin. Fish collections were carried out between 2012 and 2014, using gill nets and seine. A total of 1896 specimens, belonging to 14 species and five orders were analyzed. The allometric coefficient b ranged from 2.69 to 3.78. A new record of length-weight relationship is presented for Curimata cisandina (Allen, 1942). The comparisons with other Amazonian studies indicated differences in the parameters a and b of LWR with this study for the species Triportheus angulatus (Spix & Agassiz, 1829), Mylossoma duriventre (Cuvier, 1818), Roeboides myersii Gill, 1870 and Pellona castenaena Valenciennes, 1847 and only parameter b for Psectrogaster amazonica. The results presented in this work contribute to a better knowledge of fish resources in the region of the Peruvian Amazon, especially in the Napo River basin.

Fish Species Composition

Abstract: Knowledge of the fish species in river basins is among the minimum requirements for the management of water and fish resources. Therefore, the aim of this study was to update the fish species composition of the Piquiri River basin, upper Paraná River basin. Data were gathered from recent information published in specialized literature and records for ichthyology collections. This update reports the occurrence of 152 fish species distributed in 8 orders, 31 families, and 89 genera. Non-native species accounted for 20% of all species, and the construction of the Itaipu Power Plant and its fish ladder were the main vectors of introduction. Three percent of the species were endangered, and 11% were classified as migratory. The Piquiri River basin harbors a large number of species, some of which are rare, endangered, migratory, endemic, and even unknown by science. Because of this, maintaining the integrity of this river basin will support the persistence of regional biodiversity.

High Diversity

The Tatuí river hydrographic basin locates in low Sorocaba river basin in São Paulo state, Brazil. A relatively high diversity of fish species was noticed at that place, whose habitats are also presumed to be diversified. The Tatuí river is an important tributary of Sorocaba river, with great number of smaller streams and marginal lagoons. Fishes were collected using gill-nets, purse seines, sieves and traps, line and hook, every month during one year (from May 2009 to April 2010). Fish species were 51, including seven orders and 18 families. Characiformes and Siluriformes were the most represented with respectively 26 and 14 species.

First Time

Badis badis (Hamilton, 1822), a freshwater fish species, has been reported for the first time from the Godavari River basin of Telangana State, India.  One specimen of B. badis was collected from a stream near Mubarakpur Village in Sangareddy District (Manjeera sub-basin) and another from a stream near Sirpur (T) Town in Asifabad District (Wardha sub-basin), Telangana State, India.  This publication provides information about B. badis occurrence in India, a short description of the collected specimen, and a discussion on its habitat and threats.

The Sorocaba River hydrographic basin locates in a sub-area known as Superior Medium Tietê in São Paulo State. The study was made in the low Sorocaba River. A relatively high diversity of fish species was noticed at that place, whose habits are also presumed to be diversified. The river in this region shows some important tributaries, which are the Sarapuí, Tatuí and Guarapó, and also a great number of smaller streams and marginal lagoons. Fishes were collected using gill-nets, purse seines, sieves and traps, line and hook, every month during two years. Fish species were 55, including 7 orders and 18 families. Characiformes and Siluriformes were the most represented with respectively 28 and 17 species.

Iguaçu River

The Iguaçu River is a large tributary of the Paraná River, with a highly endemic ichthyofauna due to the geographic isolation imposed by the Iguaçu falls, located near its mouth. Fish were collected monthly in four sampling stations along the Salto Osório Reservoir, from July 2003 to June 2005, using gill nets, casting nets, and long lines. Considering the entire period, 41 fish species were colleted, which belong to six Orders, 17 Families, and 27 Genera. From these, 24 species are considered endemic. Comparisons with other surveys conducted in the Iguaçu River are provided, in addition to comments on the fish endemism, even within the basin.
