SUMMARY
Daily changes in the microestructure of the sagitta otolith growth rings of Sardinella aurita larvae were related to soma'c and biochemical growth. Somatic and biochemical growth were expressed as length/age and RNA/DNA ratio, respectively. Age and the growth of 221 sardine larvae from Morro de Puerto Santo, Venezuela were estimated measuring daily increments in sagitta otoliths and morfometric characters. The nucleic acids and the RNA/DNA ratio were determined by fluorescence. The larval size structure from days 1 to 23 ranged from 2.2 to 17.0mm LS. The increase in size (SL, standard length in mm) as a function of age is expressed by LS= 2.76+0.60xage ...
