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...

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 ...

El presente trabajo tuvo como objetivo principal reportar la presencia del pentastómido Sebekia sp. colectados en Astronotus oscellatus (Agassiz, 1831) “Acarahuazu” adquiridos del mercado Belén, Iquitos, Perú, durante el mes de junio 2021. El trabajo se realizó mediante la observación, búsqueda, identificación, medición y cálculo de los índices parasitarios de Sebekia sp. colectados de la musculatura y del estómago de 30 ejemplares adultos de A. ocellatus analizados. De acuerdo a los resultados obtenidos del cálculo de los índices parasitarios, se reportó una prevalencia de 20%, intensidad media de 1,5 y una abundancia media de 0,3 de Sebekia sp. Las medidas morfométricas obtenidas muestran a ejemplares de Sebekia sp. con una longitud promedio del cuerpo de 156,29 µm y 65,78 µm de ancho. La presencia de este parásito en la musculatura de A. ocellatus despierta un ll...

The main objective of this work was to report the presence of the pentastomid Sebekia sp. collected from Astronotus oscellatus (Agassiz, 1831) "Oscar" acquired in the Belén market, in Iquitos, Peru during the month of June 2021. The work was carried out through the observation, search, identification, measurement and calculation of the parasitological indices of Sebekia sp. collected from the musculature and stomach of 30 adult specimens of A. ocellatus. A prevalence of 20 %, mean intensity of 1.5 and a mean abundance of 0.3 of Sebekia sp was reported. The morphometric measurements obtained show specimens of Sebekia sp. with a mean body length of 1560.29 µm and 650.78 µm in width. The presence of this parasite in the musculature of A. ocellatus raises an alert to the possibility of its accidental ingestion due to the consumption of its meat in preparations that use raw or undercooked ...

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...
