          Abstract

          ABSTRACT. In the north-central Chilean coast (25.5-31.5°S), zooplankton samples were analyzed in 100 oceanographic stations from six oceanographic cruises made in February of 2008, 2009, 2010, 2011, 2013 and 2014. Engraulis ringens eggs were separated and counted, thus providing data on distribution, abundance, interannual variation, and relationships with ocean surface temperature and chlorophyll-a. The egg distribution was preferentially coastal, with maximum concentrations at stations next to Esmeralda Cove (26°S) and Chañaral Cove (29°S). In this time series, which includes cold and warm periods, it was established the relationship of these biological variables with defined ranges of temperature (16,1°-18,0°C).

          RESUMEN. En la zona centro-norte de Chile (25,0°- 31,5°S), se analizaron muestras de zooplancton en 100 estaciones oceanográficas de seis cruceros oceanográficos efectuados en febrero de los años 2008, 2009, 2010, 2011, 2013 y 2014. De las muestras se separaron y contabilizaron los huevos de Engraulis ringens, para determinar su distribución, abundancia, variación interanual y la relación con la temperatura superficial del mar y concentración de clorofila-a. La distribución de los huevos fue preferentemente costera, con máximas concentraciones en estaciones ubicadas próximo a Caleta Esmeralda (26°S) y Caleta Chañaral (29°S). En esta serie de tiempo, que incluye periodos fríos y cálidos, se estableció la relación de estas variables biológicas con rangos definidos de temperatura (16,1°-18,0°C).
