| Résumé: | Whitemouth croaker Micropogonias furnieri fishery during three intensive fishing seasons in the outer area of the La Plata River (Argentina-Uruguay) is analyzed. Resource exploitation in the South Atlantic area shows a general retraction of the distribution range and an isolation of the La Plata River stock where most of the fishing effort concentrates. The species market evolution brought about, for Argentina and Uruguay, an important shift in its dynamics as of 1992, when the product insertion in Asiatic markets generated an important commercial attraction and a subsequent increase in the fishing effort by the argentine inshore coastal fleet. This caused a change in the fishery development in Argentina and the establishment, in winter, of a fleet oriented to this species in the River Salado area in the Samborombón Bay. On board and landed size samplings evidenced a decrease in the mean length in the last fishing season. Juvenile percentage in catch peaks during September, when the adult stock shows lower concentrations. However, absolute values of the juvenile catches are higher in August both years, with over 1000 t of landed juveniles. Finally, an overview of provincial and national regulatory measures taken on whitemouth croaker resource administration is included. |
