Copeia, 1983
Energy compartmentalization in migrating and nonmigratingProchilodus mariae was monitored throughout the season of gonad maturation. Both migrating and nonmigrating individuals matured sexually. Rates of maturation were similar for migrating and nonmigrating individuals of both sexes. The overall caloric density of P.

Veterinary Parasitology, 2005
This work evaluated parasitic infections by Neoechinorhynchus curemai (Acanthocephala: Neoechinorhynchidae) in Prochilodus lineatus captured between August 2000 and August 2001 in the Paraná River, Presidente Epitácio, São Paulo, Brazil. Of 87 fishes examined, 59 were infected (25 males and 34 females). High mean intensities occurred in August 2000 (45.

The coexistence of individuals in the same river and their ability to make long-distance migrations suggest that they constitute a single panmictic population; however, several studies have indicated population genetic structuring in freshwater migratory fish species.

NOVA METODOLOGIA DE HIPOFISECTOMIA EM CURIMATÃ Prochilodus brevis (PISCES, PROCHILODONTIDAE)
Revista Brasileira de Engenharia de Pesca, 2009No nordeste de Brasil, peixes reofilicos total são usados como doadores de hipófises. O presente trabalho descreve uma nova metodologia de hipofisectomia em curimatãs, Prochilodus brevis desenvolvida na Estação de Piscicultura de Paulo Afonso EPPA), da Companhia Hidro Elétrica de São Francisco (CHESF) buscando melhor utilização do peixe ...
