Abstract It is well known that the early life cycle stages of fishes are highly sensitive to chemical exposure. However, little is known about the effects of pollutants on the other life stages, due the difficulty of experimental/empirical approaches.

Five Imparfinis mirini and one Imparfinis minutus populations were studied using basic cytogenetic and molecular techniques. Cytogenetic analysis showed that I. mirini individuals presented the same diploid number 2n=58 (FN=116). However, they presented two distinct karyomorphs: karyomorph A (36m+18sm+4st) for the Mogi-Guaçu and Paranapanema basin ...

Rhamdiopsis é um gênero de bagres heptapterídeos ainda pouco exploradodo ponto de vista taxonômico. Atualmente, o gênero é composto por apenas três espéciesreconhecidas: Rhamdiopsis krugi, Rhamdiopsis microcephala e Rhamdiopsis moreirai. Oconhecimento sobre o gênero é limitado pela escassez de exemplares em coleçõescientíficas e pela ausência de ...

Here we describe anomalies in two Neotropical freshwater fishes. Case 1 refers to a tumour above the left pectoral fin near the operculum of a specimen of Rhamdia quelen (Heptapteridae). Case 2 is a horizontal plane dichotomy of the caudal filament of an individual of Gymnotus cf. sylvius (Gymnotidae).
