Abstract: Se analizan los cambios observados en la frecuencia, abundancia y distribución del copépodo calanoideo Centropages brachiatus, especie indicadora de aguas costeras frías (ACF), antes, durante y después del evento El Niño Costero 2017. Entre marzo 2016 y noviembre 2017 se realizaron 12 muestreos bio-oceanográficos frente a la zona costera de Lambayeque, se obtuvieron 84 muestras de zooplancton recolectadas con red Wp2 a nivel superficial en una sección perpendicular a la línea costera, hasta 50 mn, entre la cal… Show more

Torres et al (2021) report the disappearance off the north coast, at least between February and October 2017 (i. e. up to 5 months after the end of the event) of the copepod Centropages brachiatus, a species characteristic of CCW (Gutiérrez et al, 2005). This disappearance was followed by the occurrence of the copepods Centropages furcatus (SEW indicator), Acartia danae, and Oncaea conifera (SSW) off the coasts of Lambayeque and Chicama.…”
