The aim of this study was to evaluate the prevalence, abundance and average intensity of plerocercoids (PLs) of Adenocephalus pacificus in the most important commercial fish species from the Peruvian coast. A total of 28 species of fish were sampled and 12 017 specimens were analysed. The presence of PLs of A. pacificus were determined from Peruvian anchovy (Engraulis ringens), lorna drum (Sciaena deliciosa), striped mullet (Mugil cephalus), horse mackerel (Scomber japonicus), Peruvian rock sea bass (Paralabrax humeralis) and cabinza grunt (Isacia conceptionis) with a prevalence of 0.55, 24.96, 0.56, 1.79, 1.53 y 3.94%, respectively. Three different types of scolex of A. pacificus PLs, like as spherical, lanceolate, heart-shaped were identified, regardless of the host, area and sampling period.

Engraulis ringens (Jenyns, 1842) “anchoveta”, es un recurso hidrobiológico de gran importancia en el mar peruano, por ser el alimento para diversas especies marinas. El objetivo del presente estudio fue determinar los descriptores ecológicos parasitarios de Adenocephalus pacificus (Nybelin, 1031) en E. ringens en las zonas de Pisco, Paracas y Callao, Perú. Se analizaron 3519 hospederos durante agosto 2014 a julio 2015. Se encontró el cestodo zoonótico A. pacificus, en estado plerocercoide en la cavidad celómica, con una prevalencia, abundancia media e intensidad media de 1,35%, 0,01 y 1,02, respectivamente. No se observaron diferencias significativas entre la prevalencia, abundancia e intensidad media de infección por A. pacificus para las zonas evaluadas y para la estacionalidad anual. La prevalencia de infección por A. pacificus fue mayor durante el 2014 en comparación al ...
