  abstract = {{S}ix indicators were investigated for {S}outh {A}frican sardine {S}ardinops sagax and anchovy {E}ngraulis encrasicolus: mean length of catch, length-at-50% maturity, total mortality, exploitation rate, ratio of bycatch, and centre of gravity of commercial catches. {S}ardine length-at-50% maturity is the most promising as a descriptive indicator because it is positively correlated with population size for an extensive time period (1953-2005). {T}he remaining indicators were limited by shorter data-series (1984-2005). {H}owever, mean length of catch, ratio of bycatch and exploitation rate were found to be useful when considered in conjunction with other indicators. {T}he centre of gravity of commercial sardine catches has shown a significant eastward shift from the {W}est {C}oast, whereas that of anchovy has remained off that coast. {R}atio of bycatch indicates that school composition is a reliable descriptive indicator of relative abundance in the two species. {F}ewer indicators for anchovy were useful, which is attributed to this species' flexible life-history pattern.},
