Se estudió la actividad pesquera sobre el stock bonaerense de anchoíta (34º S-41º S) entre 1993 y 2011 (Atlántico SO, Mar Argentino). Los datos básicos fueron los registros de captura de la flota comercial. Los desembarques anuales alcanzaron un mínimo de 5.900 t en 1999 y un máximo de 36.300 t en 2004. Las mayores capturas fueron realizadas por la flota de altura fresquera: 11.800 t en promedio. Los barcos costeros aumentaron su participación a partir de 2003, al mismo tiempo que disminuyó la de las lanchas de rada hasta valores muy modestos, desembarcando desde 2004 hasta 2011 menos de 3% del volumen total. La mayor actividad pesquera se desarrolló entre 37º S y 41º de latitud, y desde agosto hasta noviembre, siendo Mar del Plata el principal puerto de descarga. La captura media por viaje de pesca, así como el HP medio de las embarcaciones, aumentaron a partir de 1999 en la flota costera, manteniéndose en las otras dos flotas aproximadamente estables durante el período.
The fishing activity on Argentine anchovy Northern stock (34º S-41º S) during the 1993-2011 period was studied (SW Atlantic Ocean, Argentine Sea). The basic data derived from the commercial fleet catch records. Annual landings reached a minimum of 5,900 t in 1999 and a maximum of 36,300 t in 2004. The largest catches, performed by the offshore ice chilling fleet, averaged 11,800 t. As of 2003 it was observed an increase in the coastal ships share and a decrease in that of the inshore fleet that in 2004-2011 represented less than 3% of total landings. The major activity, developed between 37º S-41º S in the August-November period, had Mar del Plata as the main port of landing. The average catch per trip and the mean HP of ships, that as of 1999 increased in the inshore fleet, remained constant in the other two.
