Abstract

The gamitana is a species of socio-economic importance in the Peruvian Amazon, often intensively produced locally for human consumption. Because of this, more studies concerning parasite populations affecting this species’ culture are necessary. In this study, a heavy copepod infestation of Perulernaea gamitanae is reported in a managed culture of gamitana. The prevalence of infection was 100% and mortality of the fish population was complete. The average intensity and abundance of the parasite was 268.8 parasites per individual.
