  abstract = {{C}onsidering the wide geographic distribution and the catches of #{S}ardinella aurita$, the observed allozyme diversity ({H} = 0.011) is strikingly small. {P}otential explanations for this low gene diversity, which include restrictions on effective population size owing to variance in reproductive success, demographic instability, historical bottlenecks in population size, selection, and technical artifacts are examined and quantified. {T}his quantification, though rough, shows that no single factor can account for the lack of diversity. {H}owever, demographic instability of #{S}. aurita$, especially if this instability has persisted over evolutionary time scales, together with much greater than {P}oisson variance in individual reproductive success, could account reasonably for the results. {P}leistocene reduction of population size seems also a necessary co-factor. {T}echnical artifacts, mostly scoring difficulties linked to liver autolysis, are considered also and analysed in different clupeid species.
