This contribution presents von Bertalanffy growth parameter estimates for species/stocks of jack mackerels of the genus Trachurus from around the world, and compares them with growth parameters for T. symmetricus murphyi caught off central-Chile (33 super(o)S-39 super(o)S). It is found that Trachurus stocks inhabiting upwelling areas such as the Humboldt and Benguela current systems grow better than their ecological equivalents in temperate waters, such as the North Sea. The von Bertalanffy growth paramters estimated from Chilean horse mackerel are: FL = 65.2 cm (TL = 71.6 cm) and K = 0.138 year super(-1).
