Resumo A introdução de espécies exóticas invasoras (EEI) está entre as principais causas perda da biodiversidade no mundo. chegada dessas provoca vários desequilíbrios meio natural. O estabelecimento destas depende do transporte, entrada, sucesso adaptativo e interações ambiente. Este trabalho tem como propósito apresentar 12 peixes exóticos invasores que ocorrem em ambientes naturais Brasil na...

A study was conducted to determine the growth performance and bioaccumulation and tolerance of metal mixture toxins in five fish species including Labeo rohita, Catla catla, Cirrhina mrigala, Hypophthalmichthys molitrix and Ctenopharyngodon idella separately, under chronic exposure of metal mixture (Fe + Zn + Pb) at sub-lethal concentrations (1/3 of LC50) for 12 weeks period. Moreover, response...

Genetic variation and inheritance of randomly amplified polymorphic DNA (RAPD) markers in female grass carp (Ctenopharyngodon idella) and male bighead carp (Hypophthalmichthys nobilis) and their F1 offspring hybrid have been studied. For this purpose, genomic DNA was extracted from muscle tissue according to phenol-chloroform method, and six decamer primers were used for amplifying polymorphic ...
