Physiological effects of gasoline on the freshwater fish Prochilodus lineatus (Characiformes: Prochilodontidae)
The purpose of this work was to evaluate the effects of the water-soluble fraction of gasoline (WSFG) on the Neotropical freshwater fish Prochilodus lineatus. The WSFG was prepared by mixing gasoline in water (1:4) and animals were exposed for 6, 24 and 96h to 5% diluted WSFG or only to water.

15 صفحه اولTransmission rate variation among three B chromosome variants in the fish Prochilodus lineatus (Characiformes, Prochilodontidae).
Cytogenetic studies were developed in Prochilodus lineatus (Valenciennes 1836), describing an interesting system of small supernumerary chromosomes. The purpose of this work is to study the frequency and morphology of B chromosomes in individuals from the parental line and the inheritance patterns of these elements in individuals obtained from controlled crosses in the species P. lineatus. The ...
