Resumen:
Nutritional condition studies allow the assessment of physiological state of larva and thus, the detection of favourable nursery areas which provide good survival and growth opportunities. The main objective of the present work was to assess nutritional condition of Engraulis anchoita larvae collected in Northern Argentinean coasts by means of morphometrics, histology and RNA/DNA index. Larval condition was compared between areas characterized by dissimilar oceanographic scenarios. In general terms, larval condition was relatively high at all stations, but our results suggested that it was slightly better in frontal areas characterized by water masses with intermediate salinities.
