El objetivo del presente trabajo fue evaluar la fauna parasitaria de dos especies de peces, Pseudoplatystoma punctifer “doncella” y Pseudoplatystoma tigrinum “tigre zungaro” procedentes del mercado Belén – Iquitos – Perú, entre los meses de enero a octubre del año 2019. Se realizó mediante la observación, búsqueda e identificación de la fauna endoparasitaria en estas dos especies (50 individuos por cada pez procedentes del mercado Belén). El análisis de los peces se llevó a cabo en el Laboratorio de Parasitología y Sanidad Acuícola del Instituto de investigaciones de la Amazonia Peruana (IIAP). En el presente estudio fueron identificadas 6 nemátodos (4 géneros y 2 especies) sin haber encontrado otros grupos parasitarios, siendo 4 de ellos endoparásitos con potencial zoonótico (Anisakis sp., Contracaecum sp., Eustrongylides sp. y Pseudoterranova sp.); así mism...

The aim of this study was to identify zoonotic parasites in the musculature and visceral cavity of Hoplias malabaricus "fasaco" from the Belén market in Iquitos, Peru. The visceral cavity was reviewed through a longitudinal cut from the opening of the anus to the height of the gills. Besides, fine cuts were made in the musculature of the fish to detect encysted or free parasites. Nematodes were clarified using lactic acid, Hoyer's medium was used for pentastomids, and trematodes were stained with Langeron's alcoholic carmine. The presence of zoonotic endoparasites was observed: L3 larvae of the nematode Eustrongylides sp Jagerskiold, 1909 (Dioctophymatidae), the trematode Ithyoclinostomum dimorphum Witenberg, 1925 (Clinostomidae) and the pentastomid Sebekia sp.

The Amazonian ichthyofauna is very important for the commercial development of the Peruvian Amazon, being fish meat the main source of animal protein consumed by the Amazonian population. Despite the high demand for fish in the city's markets, little is known about the parasites present in its meat, and there is a potential risk of acquiring a zoonotic parasite. In this sense, the present study aimed to identify endoparasites in fish sold in markets in the city of Iquitos, reporting the presence of zoonotic parasites in internal organs and the musculature of the fish. Fish samples were acquired from the “Modelo”, “Secada”, “Cardozo” and “Belén” markets, located in Iquitos, Loreto, Peru. In total, 29 species of fish were analyzed, examining the internal organs, cavity and musculature. The results obtained allowed the identification of 15 genera and 22 parasitic species (e...

En este trabajo se registra una nueva especie de Monogenoidea, Cosmetocleithrum amazonensis n. sp., parasitando las branquias del silurido Auchenipterichthys coracoideus (Eigenmann & Allen, 1942). Cosmetocleithrum amazonensis n. sp. se distingue de todas las demás especies congéneres por poseer un órgano copulador masculino (OCM) tubo alargado, esclerotizado y sinuoso, con espirales poco definidos, base con borde esclerotizado y con la región distal apoyada sobre la pieza accesoria. La pieza accesoria es una placa única, robusta y no articulada con el OCM. En este estudio se presenta el tercer registro de una especie de Monogenoidea en un hospedero Auchenipteridae (Siluriformes) del Perú. Publicación registrada en Zoobank/ZooBank article registered:LSIDurn:lsid:zoobank.org:pub:A2885133-CCFE-45FE-B97C-21C2C128FD5DActo nomenclatural/nomenclatural act:Cosmetocleithrum amazonensis...

Las tilapias son peces introducidos a América Latina y son considerados como perjudiciales para los ecosistemas naturales. Se ha detectado la presencia de estos peces en cuerpos de agua naturales y en estanques de cría en la Región de Loreto, Perú. En el presente estudio se analizaron las branquias de Oreochromis niloticus “tilapia” procedentes de un estanque de cultivo del eje carretero Iquitos-Nauta, pudiendo identificar al monogenoideo Cichlidogyrus tilapiae parasitando a O. niloticus. Este sería el primer reporte en la región de una especie de Monogenoidea colectada de las branquias de un pez exótico.

In the rearing of native fish of the Peruvian Amazon such as Colossoma macropomum, Piaractus brachypomus, Brycon amazonicus, Prochilodus nigricans and Arapaima gigas, balanced feed is used, in whose formulation fishmeal and other non‑local inputs predominate. This makes its acquisition more expensive and difficult, mainly by rural Amazonian producers who are far from the urban area. Worldwide, there are experiences of alternatives for raising fish based on the use of vegetables, fruits and insects, taking advantage of the biological diversity of the environment. Thus, the use of insect larvae constitutes a promising alternative for the aquaculture sector on a global scale. The present study shows the semi‑captivity breeding of Hermetia illucens "black soldier fly" using organic waste (citrus) collected from urban and rural areas, highlighting the use of orange bagasse and grapefruit ...
