Abstract
One approach to place the size of annual fishery catches of sardine and anchovy into perspective is to
contrast them with annual losses to natural mortality, which correspond to the amounts consumed by
natural predators. This is pursued here using results from the most recent assessments of these two
resources (de Moor and Butterworth 2009a,b). The methodology for computing consumption of anchovy
is set out in the Appendix; that for sardine is very similar.
