    espanolEl objetivo de este estudio fue estimar la mortalidad natural en los estados embrionarios y larvales de la sardina europea Sardina pilchardus a largo de la Costa Atlantica del Noroeste de Africa entre el Cabo Barbas (22°30'N) y el Cabo Bojador (26°N) durante noviembre de 2007. Se utilizaron datos planctonicos seleccionados de un estudio realizado en noviembre 2007 y ajustados a un modelo exponencial; el indice de mortalidad de huevos de sardina (Z) fue estimado en 0,07 (por hora), siendo el indice de mortalidad diario del 83,5%. Por otra parte, para larvas de sardina, Z fue estimada en 0,1 (por hora), correspondiente a un indice de mortalidad diario igual al 21,4%. Migraciones hacia el sur y costa afuera pueden ser consideradas como una causa de la variabilidad en la deriva y condiciones de sobrevivencia de larvas de sardina. Analisis adicionales de serie de tiempo de las primeras etapas del ciclo vital de las sardinas y la futura supervision con programas de monitoreo adaptativo deberian ser conducidos para un mejor manejo de la industria pesquera de esta especie en Marruecos. EnglishThe purpose of this study was to estimate the natural mortality of embryonic and larval stages of European pilchard Sardina pilchardus along the Atlantic Coast of Northwest Africa between Cape Barbas (22°30'N) and Cape Bojador (26°N) during November 2007. Using planktonic data that were fitted to an exponential model, sardine eggs hourly mortality rate (Z) was estimated in 0.07 (per hour) corresponding to 83.5% of daily mortality rate. On the other hand, for sardine larvae, Z was estimated in 0.01 (per hour), corresponding to a daily mortality rate of 21.4%. Southward and offshore transport can be considered as causes of variability in drifting scenario and survival condition of sardine larvae. Additional analyses of time series of the early life history data of sardines and future adaptive monitoring should be conducted to better manage sardine fisheries in Morocco.
