Abstract
The paper was developed in order to arrange the data gathered on this subject and to generate new hypotheses in connection with the trophic strategy of the northern stock of anchovy in the area between latitudes 35°-42°S. Such estimates were finally compared with the values of the gravimetric determinations of stomach contents- as converted to caloric values - of individuals grouped by total-length amd age classes, ecological areas, and seasons of the year. The set of results as obtained conforms the initial basis for developing Part IV of the Trophic Ecology of the Argentine anchovy as related to food consumption estimates, by stock biomass and annual classes, with back-calculations to age class 0, and for applying "regional patterns" that result from the "consumer-food" relationship.
