Pirarucu ( Arapaima gigas) has been one of the most important economic resources among all the fish species of the Brazilian Amazon for more than three centuries. The introduction of modern technologies of exploitation brought serious threats to the preservation of this species. Adequate management strategies have to be urgently introduced in order to prevent extinction. The aim of this work is to present a mathematical model for the pirarucu population dynamics considering the species peculiarities and the different fishing rates to supply subsides for its conservation. In order to differentiate its respective role in breeding, the population is divided into two groups: female and male. The parameters introduced in this paper are derived from limited but reliable field data collected at the Mamirauá Sustainable Development Reserve (MSDR) in the Brazilian Amazonian Region. Complementary parameters are estimated from biological considerations and commonsense.
