The “gamitana” Colossoma macropomum is one of the most important species of the Amazonian ichthyofauna, highly demanded and with significant potential for fish farming and Amazonian development. This species, like others in the Amazon, are affected by parasitic infestations and infections, highlighting infestations by branchial monogenoids, for which, over the years, different chemical products based on various components have been used as treatments. Currently there is a trend for the use of low-cost, easily accessible products that are in harmony with the environment and that also provide good results to combat parasites in farmed fish. Thus, the present work evaluates the efficacy of common salt and garlic extract to reduce the parasitic load of branchial monogenoids present in the “gamitana” C. macropomum. This study was carried out with fish collected from fish ponds at the ...

Colossoma macropomum popularly known as gamitana is one of the most important species of the Amazon ichthyofauna, highly demanded and with significant potential for Amazon fish farming and development. The “Instituto de Investigaciones de la Amazonía Peruana” (IIAP) incentives sustentable pisciculture through tecnological transference of native amazonian fish species, manily the gamitana. These fish are stocked in culture ponds of different owners, who in turn have to consider certain prophylactic measures to guarantee the adequate growth of the fish for subsequent commercialization in the markets of our city. In this sense, the present work aims to contribute to the knowledge of the species of parasites present in the gamitana, in order to obtain the necessary information for the proper management of this resource. In the present study, 60 specimens (30 fingerlings and 30 juveniles...

El estudio se realizó en las instalaciones del Centro de Investigaciones Fernando Alcántara Bocanegra (CIFAB) del Instituto de Investigaciones de la Amazonía Peruana (IIAP), Iquitos; con el objetivo de conocer el comportamiento parasitario de Dolops discoidalis (Bouvier, 1899) (Crustacea: Branchiura) en tres especies de peces. El muestreo se realizó durante los meses de noviembre y diciembre del 2018. Para este estudio se extrajeron individuos de esta especie de parásitos de la superficie corporal de ejemplares adultos de Pseudoplatystoma punctifer (Castelnau, 1855), criados en cautiverio en las instalaciones del CIFAB. Los parásitos colectados fueron llevados al Laboratorio de Parasitología y Sanidad Acuícola del IIAP para ejecutar dos experimentos relacionados al comportamiento parasitario de D. discoidalis en tres especies de peces: P. punctifer, Colossoma macropomum (Cuvier, ...

This study was carried out at the facilities of the “Centro de Investigaciones Fernando Alcántara Bocanegra (CIFAB) of the “Instituto de Investigaciones de la Amazonía Peruana (IIAP), Iquitos; with the objective of knowing the parasitic behavior of Dolops discoidalis (Bouvier, 1899) (Crustacea: Branchiura) in three fish species. The sampling was carried out during the months of November and December 2018. For this study, individuals of this parasitic species were extracted from the body surface of adult specimens of Pseudoplatystoma punctifer (Castelnau, 1855), bred in captivity at the CIFAB facilities. The collected parasites were taken to the laboratory of “Parasitología y Sanidad Acuícola” of the institute (IIAP) to perform two experiments evaluating the parasitic behavior of D. discoidalis in three fish species: P. punctifer, Colossoma macropomum (Cuvier, 1816) and Brochi...
