Summary

Synoptic mapping of macrobenthos related with diet of white croaker Micropogonias furnieri in El Rincón. November, 1994. The faunistic characteristics in feeding grounds of Micropogonias furnieri, considering many relationships with the diet of the species in the Argentine-Uruguayan Common Fishing Zone, are studied. Benthos was collected in 33 sampling stations during the reseach cruise H-13/94, between 9-44 meters depth in the area El Rincón (Buenos Aires Prov., Argentina), with hard bottom and Picard dredges. Cluster analysis (Q mode, Sorensen index) was applied to these data and to the invertebrate by-catch obtained in 58 demersal hauls. Frequency size distribution of mussels in its distribution area is also presented. Stomach contents of 177 specimens of white croaker were studied from the percentage of ocurrence frequence of every alimentary item. Present results and previous information from the area of Río de la Plata suggest that traditional fishing areas of white croaker in the Argentine-Uruguayan Common Fishing Zone constitute feeding grounds for this commercial resource.
