ABSTRACT: From February 12 to March 27, 2019, a hydroacoustic assessment cruise for pelagic resources (1902-03) was conducted aboard the R/Vs Olaya and Humboldt along the Peruvian coast. The cruise aimed to study the ichthyoplankton, euphausiids, and zooplankton biovolumes. A total of 32 families and 64 species of ichthyoplankton were identified, with Engraulis ringens eggs and larvae being the most abundant, ranging from 3 to 17,952 eggs.m-2 and from 3 to 1,500 larvae.m-2. The highest spawning concentrations were found in the coastal area between Talara and Cerro Azul. Eggs and larvae of Vinciguerria also showed significant concentrations, with values of 3 to 2,553 eggs.m-2 and from 3 to 222 larvae.m-2, distributed outside the continental shelf. Thirteen species of euphausiids were also identified, with Euphausia mucronata being the most abundant. Zooplankton biovolumes ranged from 0.01 to 8.78 mL.m-3, with values >0.5 mL.m-3 distributed mainly outside the 10 nm zone.
A bordo de los BIC Olaya y Humboldt, del 12 de febrero al 27 de marzo 2019 se realizó el Crucero de Evaluación Hidroacústica de Recursos Pelágicos 1902-03. Fueron determinados huevos y larvas de 32 familias y 64 especies de ictioplancton. Los huevos y larvas de anchoveta fueron más abundantes, variando de 3 a 17 952 huevos.m-2 y de 3 a 1 500 larvas.m-2. Desde Talara hasta Cerro Azul, en la zona costera fueron localizados mayores desoves. Los huevos y larvas de Vinciguerria también presentaron importantes concentraciones con valores de 3 a 2 553 huevos.m-2 y de 3 a 222 larvas.m-2, distribuidos por fuera de la plataforma continental. Además del ictioplancton, fueron determinadas 13 especies de eufáusidos, siendo Euphausia mucronata más abundante. Los biovolúmenes de zooplancton oscilaron entre 0,01 y 8,78 mL.m-3, con valores >0,5 mL.m-3 distribuidos principalmente por fuera de las 10 mn.
