Resumen:
The relation between the feeding and mortality of fish larvae is mediated not only by starvation but also by
their growth . In this work, daily otolith ring deposition was analysed in laboratory-reared larvae of Odontesthes
microlepidotus (Jenyns), and their growth was studied in relation to ring number and otolith diameter .
The nutritional condition of these larvae was assessed by means of morphometric comparisons between fed
and starved larvae in order to develop a tool to evaluate the nutritional status of larvae in breeding areas .
Changes in body shape have been found as a consequence of starvation . No dependence was found between
mean hepatocyte nuclear area and fasting .
