Abstract
    In these investigations the potential total fecundity of horse mackerel was estimated, using both a volumetric and a histometric method. The traditional standard volumetric method was used for estimating the total fecundity and ovaries in prespawning condition were digested in Gilson's fluid. The histometric method, which has been developed at the Fisheries Laboratory Lowestoft (UK), has a number of advantages. The use of Gilson's fluid, a persistent poison, is avoided and maturity stages can be confirmed by identifying post-ovulatory follicles. In addition, the size at which oocytes become vitellogenic can be measured and largely because digestion in Gilson's fluid is unnecessary, the method is much quicker.
