Abstract: The chub mackerel Scomber japonicus and anchovy Engraulis anchoita commercial landings at the Mar del Plata (Buenos Aires prov., Argentina) seaport during the September 1999-January 2000 period are studied. A total of 14 chub mackerel samples were taken for total length measurements exclusively and 5 anchovy sub-samples and 1 chub mackerel sub-sample were analyzed to record individual data total length, weight, sex, sexual stage, age from otoliths readings . Most of the fish caught for both species were adults and only a small fraction of chub mackerel juveniles was found in December 1999. Length-at-fifty-percent-maturity was calculated, length-weight and length-age relationships were fitted and length growth parameters estimated. Sea surface temperature SST in the fishing area was recorded on board of a sampling boat. Chub mackerel CPUE, that showed a decrease when SST increased, was calculated. Data from landings of the different fleets for both species as well as the significance of these resources to the small purse-seine fleet economy were analyzed.
