Abstract

 The growth parameters of the North Sea mackerel Scomber scombrus Linnaeus, 1758, like most other temperate species, are estimated  from length at age data. Ageing of mackerel is based on otolith reading. In this study, it was attempted to apply the latest versions of computerized length frequency analysis in order to estimate the growth parameters of the North Sea mackerel and also to compare the  results with those obtained using length at age data. The growth parameters, Loo and k values estimated by the length frequency analysis were considered very much acceptable when compared with the values from length at age data. The t0 value, however, could not be obtained through the length frequency analysis.
