Abstract
The trend with length in parasite prevalence in sardine on the South Coast is modelled in a
manner that isolates behaviour at larger lengths to enable a determination of whether the trend
continues to increase from age one to ages of two and above. The results indicate that a
continued increase is robustly confirmed at the 5% level of significance, and hence that there
must be some movement of sardine of ages greater than one in at least one direction between
the West and the South Coasts under the hypothesis that infection by the parasite can occur
only on the West Coast.
