Abstract
    Conversion factors are determined for 8 important South African trawled fish spp. The conversion factor for each sp was calculated as the ratio of total whole wt to total cleaned wt in each sample. The landed wts of selected spp caught from 1917-1974 have been converted to live wt by means of the conversion factors obtained from the study of the 8 fish spp.
